2024.05.18 16:31 AvailableAnteater341 Tethered powered drone - Voltage regulator system design
Hello,
I am building a tethered drone used in washing houses and solar panels, most important aspect being the overall drone system weight.
The overall use would be washing up to 15M high with a drone (Phantom 3 or similar modified). Overall consumption is around 200 W.
Now, i aim at designing a system that is going to be able to provide 15A at 15V over a length of wire of 15-18 meters, 1 to 1.5 mm section, while powered from a 24V 20A AC-DC power supply.
The drone will not have an installed battery, will run only from the tethered source. (This would remove around 400G weight on takeoff to be used by the water supply hose).
I don't want to run higher voltage, either AC or DC due to safety reason in operation.
I explored sending AC-AC and using and bridge rectifier setup + voltage regulator on drone to provide the voltage, but i cant find and suitable 220-24 AC-AC transformer that can supply 15-20-30A.
The big problem is the power loss in the DC-DC cable portion from the ground power supply to the drone where the voltage will be dependent on the drawn current. AT 15A over the full length of the wire with 1.5mm section the voltage loss would be around 5V for a total of almost 100W power loss in the wire, leaving me with a 20V 15A power supply at the end of the wire.
I plan on building an array of 20 1A linear regulators so i can provide an steady 15V-15A power supply in the drone(I want to build it like this for weight reason, as the overall voltage regulator would weight at around 60G, air cooled).
Would this be a suitable setup or there are better ideas to build the drone power supply?

2024.05.18 16:17 Snuffcan Hifi Engine Help
 | Happy Saturday morning from DC! I recently acquired a JVC 4vr-5446. I’m new to this hobby and am starting a restore on this unit. I was able to find the service manual and schematics on the internet archive but can only source the instructions/ owners manual at Hifi Engine. It seems like they are closed for new accounts so the docs aren’t available to download. Can anyone with an account help me access that document? I have included an obligatory (freshly relamped) picture of this green monster! submitted by Snuffcan to vintageaudio [link] [comments] |
2024.05.18 06:25 LowYak3 How does the input AC current flow through an amplifier?
 | Is there any schematic that has arrows showing the direction of the AC and not just the direction of the DC. Does the input signal flow through Rc? I can’t picture how the current of the signal travels through this circuit. It looks like the current coming from the input would only flow from base to emitter. submitted by LowYak3 to ElectricalEngineering [link] [comments] |

I changed the template, bullet points, and added some new things. I recently graduated last year with a bachelor's in ECET, and I have been applying for jobs for the past 5 or so months with little to no success, only getting around 3 interviews with 120 applications. Most of them have been silent. I would like the subreddit's advice on how to improve the resume or I should start over. I know the major I picked is not ideal and the job market is not great atm, I'm just trying to work with it. I've been applying to entry level electrical engineer jobs, where I do hit around 50-60% of the requirements, although it's tough finding one that doesn't need 5+ years of experience or an EIT certification. I would like the subreddit's advice on how to improve this resume, much appreciated. I apologize to the mod team for screwing up my past submissions. I think it was due to me changing the line spacing and font size of my past submission, as I wanted it to be more readable. Although I didn't move the sections as I was afraid of messing up the formatting. Notes:

2024.05.17 17:27 nuk3man Problem with smoothing caps & rectifier bridge
Hi. I'm following GreatScotts guide to build a function generator! and Circuit schematic is here!.
I've come accross a peculiar issue when scoping the lines going out from the rectifier to voltage regulators.
The issue is that the line that goes into the 7912 voltage regulator isn't smoothed out nearly as much as the line that goes into the 7812 voltage regulator. Here is an image comparing both on my scope!.
I have the exact same model of caps on both lines. My first thought was that one cap must be bad, so I simply switched them around to compare but it's still not smoothed out.
Any ideas what could be causing this?

2024.05.16 20:13 Rootthecause Exploding GaN Issue (Synchonous Rectification)
 | Hi, I'm looking for advice on a (hopefully soon to be) open source project I'm working on. It is an LLC converter that converts 400-600V to 24V and provides up to 750W. The old version works, but the synchronous rectification with MOSFETs gets too hot. So I switched to the NCP4305 with 4.5V clamp and use GAN3R2-100CBEAZ HEMETs. The rectification with GaN basically works and I have already been able to rectify 150W. submitted by Rootthecause to ElectricalEngineering [link] [comments] Center: GaN HEMETs, above them are the NCP4305s - pls ignore the \"GaNdalf Approved\" 🥲 However, a problem has arisen for the second time: At low load, the NCP4305 shortens the time during which the gate is high until it is completely deactivated (skipping). Gate-Source graph for one (half wave) SR. Gaps in the gate-source graph indicates cycle skipping at low loads. With a sufficiently high input voltage (approx. 200V primary side, secondary is regulated to constant 24V), this leads to the HEMETs heating up to over 200°C in 100ms - and permanently losing their function. My assumption is that the skipping causes a current to continue to flow through the HEMET (reverse conduction) and leads to overheating. However, this does not seem particularly logical to me either, because during the test approx. 50 mA flowed at the output and the source-drain voltage is 1.5 V → 75 mW (peak perhaps more). The data sheet of the NCP4305 mentions the optional use of the Light Load Detection pin. This reduces the gate voltage if the output voltage exceeds a certain value at light load conditions. The reasons given for using the LLD pin are better efficiency for FETs with large input capacitance and improved stability during load transients. The efficiency was secondary to me at this point, which is why I have pulled the LLD pin to GND (disabling LLD). The used schematic is mostly like the one provided in the datasheet. Note: Only one HEMET per side was used while testing. R68/R73 set the minimum ON-Time for the Gate (1k = 125 ns, 10k = 1000ns). Datasheet for the NCP4305: https://www.mouser.de/datasheet/2/308/1/NCP4305_D-2317117.pdf Now I got 3 questions:
Edit: Here are the V_DS vs. V_GS graphs: https://preview.redd.it/tylqfl7bz21d1.png?width=1280&format=png&auto=webp&s=78b93e47ad01468c02d0d06e8814781365da270a Yellow/Cyan: DS/GS Voltage for one half of the scondary winding Purple/Green: DS/GS Voltage for the other half of the scondary winding The output voltage in this diagram was 7.0 V, which almost matches the peak-to-peak voltage (Upp = 2 * U_out). https://preview.redd.it/4apw60k9031d1.png?width=1280&format=png&auto=webp&s=49fdd0bc1b0996b341a6d39acbc528fcc65a53db Same Setup, but for U_out = 14 V and lower switching frequency. Note: The time/div and U_ds/div is different from the previous figure. So far, it looked good, so I increased the input voltage. At 17V on the output I could hear some slight noise. When I just wanted to figure out, if gate turn on cycles are beeing skipped, I got the bang again :( Both HEMETs died and I got zero spares. New ones will take some days to deliver. I'm not quite sure if the little spikes on the gate curves are really there or just EMI from using 15cm alligator clips for grounding - or EMI has gotten into the gate from the probe. If it is really there, could that be the whole problem? It seems to be coming from the half bridge on the primary side. But the capacitance between prim and sec is only 8 pF and the Y-cap between the grounds is 3300 pF, which is plenty for compensating common mode interference (I did test this a while ago with different capacitances). |
2024.05.16 15:53 FineTechnician4966 Possible to use DC powersupply to power AC Mixerboard? (Behringer UB802 that has AC input)
Hi!
I have a behringer UB802 mixerboard without a powersupply. I'm wondering if it would be possible to use a DC-powersupply to power it?
The original AC-PSU outputs 2 * 17.5V (180 degree phase shift between the two) at 650mA + GND. I've found schematics for the board here, I was hoping to find a recitfier circuit and then simply be able to connect a DC-PSU after the rectifier - however all i see is the -15V and +15V points/rails. Does this mean that the board uses AC natively or is the powercircuitry not included in the schematics?
Would be grateful for any input or suggestion for where to post this if this is not the right sub.
Cheers

DC Next Proudly Presents:
Written by Dwright5252
Edited by Predaplant
< Prev. Next Issue > Coming Next Month
The Waverider
When she was growing up, Deirdre Harkness often thought about how things might’ve been different in her household if she had an older brother to take the brunt of her father’s attention. How her path through life could have been vastly different, her rap sheet a little more… non-existent.
Now that such a brother seemingly existed, albeit from another Earth altogether, she was starting to realize that maybe she was fine being an only child.
“Listen, this’ll go a lot faster if you stop being so obtuse, Deirdre,” Owen Mercer scowled, twirling one of his razor-sharp boomerangs deftly between his fingers as he paced the deck of the Waverider. Deirdre sat in the hot seat, the Linear Men staring at her on one side while her current and former romantic partners stood on the other. The multiversal children of Digger Harkness faced off in the middle, neither seeming to want to give any inch in their argument.
“Look, I’m just sayin’ I’d be able to find my friends better without some drongo stealing my schtick,” she responded casually, moving to take a boomerang of her own from her bandolier before remembering the new time cops had confiscated all her weapons. “Surely Jenny Sparks has someone better to send along.”
Was she being difficult? Absolutely. Was this petty argument preventing her from saving her missing teammates? Undoubtedly.
Did she want to take this pretender down a peg? You know it.
“Perhaps we can arrive at some kind of accord, beloved,” Ystin interjected, placing a hand on Deirdre’s shoulder. “I understand how jarring seeing this knave must be, but our comrades in arms are lost to time. Other priorities must take precedence.”
Sighing deeply, Deirdre fell back into the chair behind her, irked that this modified timeline removed all the progress she’d made in molding the chair to fit her form. She could see Liri wince at the force she had used to enter the chair, and felt a little bad about that.
God, she could be selfish sometimes.
“Fine. Fine, I’ll be a good sheila now. What is your plan, oh fearless brother o’ mine?” She felt the tension in the room let up slightly, and Ystin gave her a grateful smile.
Owen pulled out another boomerang of his and started pressing the buttons on it. A projection appeared, seemingly the timeline they were currently in. Biting back her instincts to make fun of her brother’s projecto-rang, she sat back and listened as he began to point at the timeline. “As you can see, this is the current stream that we’re in. You can see these discolorations,” he explained, pointing at the shades of red appearing in the mostly blue timeline, “that indicate the anomalies you’re normally after. Sure, they aren’t the best thing to have appear, but it’s within the Time Masters’ range of acceptable aberrations. From what Deirdre is saying, the kind of anomaly we’re looking for with this situation, with one team seemingly erased from time and another fully resurrected, should be lighting this up like a Christmas tree. That massive of a ripple effect from those changes would unmoor us into the Bleed, never to return.”
“But we’re clearly still here,” Rip Hunter said, scowling. “So you’re saying she’s full of it.”
“Not necessarily,” Owen replied, and Deirdre felt a slight pang in her chest as her brother came to her defense. He dialed in another setting and another hologram appeared, this time showing various circles floating around the timestream. “What do you know about time bubbles?”
Michael raised his hand, ever the teacher’s pet, apparently. “They’re basically pocket dimensions separated out from the timestream. The Time Masters use them sometimes to isolate threats to the stream or conduct experiments.”
“Gold star to you,” Owen said, and Deirdre rolled her eyes as Michael beamed. She missed Booster so much. “Yes, exactly that. So let’s say that these bubbles,” he circled a majority of them, “were made and accounted for. We’re left with a good dozen unsanctioned by the Time Masters.”
Deirdre’s hopes started to pick up before Rip dashed them. “But that’s also within parameters for a timestream. Nature abhors a vacuum and makes time bubbles naturally to fill in any blank spaces that appear. You’re grasping at straws.”
Owen turned toward the captain of the Waverider. “I’m sorry, did you want to run this presentation? I can go back to the Authority and leave y’all to your issues if you want.”
Before Rip could respond, Liri stepped in. “Rip, let the poor boy explain. You’re being an asshole.”
Deirdre blinked, surprised at Liri’s interjection. The AI she knew would never put the captain in his place like that. And even more shocking, she saw Rip pull back and motion for Owen to continue, clearly chastened by his crewmate.
Miracles did happen.
“You’re correct, the other bubbles not highlighted are indeed naturally occurring.” Owen pointed at them and expanded them. “But someone with enough access and know-how can commandeer these time bubbles and manipulate them for their own uses.”
Matthew Rider raised his hand. “So you’re saying our missing people could be inside these bubbles? But what about the damage to the timeline from removing them in the first place?”
“Good question. Like I said, this level of fuckery to the order of things should’ve made things completely unravel. That being said, it is possible for someone with a high degree of chronal knowledge and access to do it. It’d be damn risky, as one mistake could spell disaster. But… it's becoming more and more evident that whatever’s responsible for this isn’t an amateur.” Owen pulled up a blank file now, a glaring DATA NOT FOUND flashing in front of them. “You say you all saw Walker Gabriel vanish, and still have memories of him. He’s not in our databases anymore, and there’s not even a void left behind where he should be. This thing took him out and plastered over the timestream to remove any trace.”
Silence fell on the group as the idea of what they were up against sunk in. Deirdre pondered who or what could hate them enough to do something like this.
“So what’re our next steps?” Liri asked, typing away furiously at her datapad. “Should we search these time bubbles for our missing teammates?”
Deirdre smiled sadly as she heard Liri refer to her friends as teammates. This version didn’t even know these people, didn’t have any definitive proof that they even existed, and yet she took them in her heart as part of the team.
Owen shook his head. “That would take too long, and might tip off whatever’s doing this to our plan. We need more manpower for the search and a way to narrow down the field.” Roxy Rocket, who’d spent the entire conversation vlogging the control room with her camera, piped in. “Sciency stuff isn’t really my bag, but could you maybe look for people that interacted with these folks and trace them that way? Use their memories to bridge the gap or whatever?”
To Deirdre, it sounded like the kind of stupid thing that just might work. “I know someone that might be able to help us with that, and I can get some people together we could use.”
Hub City, Illinois
Something was wrong, of that Violet was certain.
Their journey had led them across the globe when they’d felt it happen, felt the universe attempting to steal another memory from them. Violet fought against the overwhelming vibrations that tried to steal the memory of their friend from them, using their powers to shield their mind and their heart. It took everything they had, rendering Violet unconscious for a day. But when they awoke, they still remembered Michael Jon Carter, Booster Gold. The first person in Violet’s memory that tried to help them.
It felt fitting, going from trying to discover their past to helping bring their friend back from oblivion.
The problem was, nothing was working.
“I’m sorry, I don’t know what you’re talking about,” Daniel Carter asserted, shifting on his crutches as he tried to close the door on Violet. They held their hand out to stop it, and felt fear trickle through Daniel’s aura.
“I do not mean to startle you, I am just trying to find some answers,” Violet explained, backing away from the door to give Daniel some space. “I know it sounds strange, but I am telling you only the truth.”
“Look, I wish you luck in… this whole thing you’ve got going,” Daniel said, “but I don’t have a clue about any future relatives of mine, whatever the hell that means. Now if you’ll excuse me, I need to get ready for a job interview.”
This time, Violet allowed him to slam the door in their face. It was no use. It seemed anyone they’d attempted to contact didn’t have any memories of their friend. Violet knew that if they could only use their aura to show Daniel the true way of things…
But no. That would be a trespass they were hesitant to employ. There had to be a way to bring Michael back without hurting anyone. They would find it, they were sure of it. “Well, if it isn’t the most colorful person I know,” a familiar voice said from behind them. Violet turned around to see Deirdre Harkness approaching them from across the street. Unconsciously adjusting their hijab, Violet ran towards their former teammate and enveloped her in a tight hug.
“You are truly a sight for sore eyes, Deirdre,” Violet said, tears running down their face as they took in their old friend’s presence. “I could really use a friendly ear at the moment. I feel as if I have gone insane.”
Deirdre pulled back from the hug to look Violet in the eye. After a moment of searching, she smiled. “You remember, don’t you?”
Violet’s eyes widened in shock and joy. “Tell me you are not humoring me. You truly remember our friend?”
A wave of relief washed over Violet, and it was all they could do to keep their aura in check as Deirdre spoke. “Not only do I remember Booster and Rip and the others, but I think I have a way to get them back.”
Radiance, Pennsylvania
Living in a mansion wasn’t all it was cracked up to be. For instance, the amount of upkeep required to keep it from becoming a dusty mountain of sadness was just completely unrealistic for one person to do. That meant hiring people to help maintain the grounds, sweep the floors, clean the bathrooms and bedrooms.
Mitch Shelley was not a fan of people.
“No, I said not to make the topiary look like a Soder Cola can,” Mitch insisted to his groundskeeper, an older man whose proximity to loud saws all his life made him hard of hearing. “It looks corny as fuck.”
The old man shook his head. “I think it looks fine, sir. Plus I know your corporate sponsors will appreciate it for that gala you’re holding next week.”
Goddammit. Mitch had been dreading that stupid party ever since he’d been asked to host it in honor of his latest sponsorship campaign for the Soder Cola company. Sure, he wasn’t too involved with the planning (at least, when he could dodge the phone calls and house visits of the party planner he’d hired) but it still took up way too much of his time. That wasn’t to mention the fact that he had to attend the thing.
In a suit.
Ugh.
“Maybe you’re right. Thanks, Joe,” Mitch said, handing the groundskeeper a generous tip. Joe was probably the most down-to-earth of his employees, and he wanted to make sure he was taken care of. Joe shook his hand appreciatively and walked out the door, brushing past a red haired woman dressed garishly in some sort of costume.
“You’re a week early for the gala, darlin’,” Mitch said, waving her away as he tried to escape to his theater room. “I’m sure whatever skill you have will be enough to entertain the suits coming to this shindig.”
“Har de har, asshole,” the woman said, her Australian accent giving him pause. What was an Aussie doing in Pennsylvania? “I’m actually here for Resurrection Man. Need his help.”
Mitch sighed, “Look, I’m sure whatever cat’s stuck in a tree will get itself out. If this is about Lazarus, tell that fucker he can come and face me himself rather than sending his new sidekick.”
The woman rolled her eyes. “Look, I know you. You’re a wild horse that can’t be reined in. You need adventure in your life, and I’m here to offer it. Ever time traveled before?”
Mitch stopped on the steps. “In a manner of speaking. What did you have in mind?” Maybe he’d hear this woman out. If anything it might last long enough to get him out of this fucking party.
Opal City
“Stargazer tipline, how can we help?” Jack Knight was surprised when the old phone line started to ring. Courtney had been right; most people used the app to ask for help. He’d almost forgotten the tipline was a thing, and it had startled him into dropping his tools as he worked on another upgrade to the Star Staff. His father’s laboratory made the ringing sound like it was coming from all over, so he’d almost missed the call when he couldn’t find the phone buried under all the schematics.
“Hello Starman, long time fan, first time caller,” a voice said from the receiver, the accent telling him this wasn’t an Opal citizen. “Need your assistance in a caper.” He was tempted to hang up the phone; no doubt this was some kind of crank call. “What’re the details of this… caper, ma’am?” He’d humor her for a little bit. Jennifer and Courtney had been on his case about crunch culture and making sure to take breaks, so maybe this could count as his allotted rest period.
“First off, I think I’m younger than you, so shove off with your ma’am,” the woman huffed. “Second, this isn’t a joke. Why don’t you come out of your little work shed and see what I mean.”
The line clicked, and Jack looked at the phone in confusion. What a weird call. There was no way anyone knew where he was at the moment, so he chalked it up to someone having a laugh at his expense. As he picked up his blowtorch to continue his welding, the intercom buzzed.
“Jack, can you please come up here and tell these yahoos to get their spaceship out of my backyard before they wreck my azaleas?” Jack heard his father’s voice resonate through the speaker. He jumped up to look at the outside cameras, and sure enough, there floated a spaceship of some sort.
He pulled out his phone and texted into the All Star Group Chat. “Hey, gang. Might need to be out of the city for a bit on a mission. I’ll keep you posted.”

The Linear Men
Issue Twenty:Family ReunionWritten by Dwright5252
Edited by Predaplant
< Prev. Next Issue > Coming Next Month
The Waverider
When she was growing up, Deirdre Harkness often thought about how things might’ve been different in her household if she had an older brother to take the brunt of her father’s attention. How her path through life could have been vastly different, her rap sheet a little more… non-existent.
Now that such a brother seemingly existed, albeit from another Earth altogether, she was starting to realize that maybe she was fine being an only child.
“Listen, this’ll go a lot faster if you stop being so obtuse, Deirdre,” Owen Mercer scowled, twirling one of his razor-sharp boomerangs deftly between his fingers as he paced the deck of the Waverider. Deirdre sat in the hot seat, the Linear Men staring at her on one side while her current and former romantic partners stood on the other. The multiversal children of Digger Harkness faced off in the middle, neither seeming to want to give any inch in their argument.
“Look, I’m just sayin’ I’d be able to find my friends better without some drongo stealing my schtick,” she responded casually, moving to take a boomerang of her own from her bandolier before remembering the new time cops had confiscated all her weapons. “Surely Jenny Sparks has someone better to send along.”
Was she being difficult? Absolutely. Was this petty argument preventing her from saving her missing teammates? Undoubtedly.
Did she want to take this pretender down a peg? You know it.
“Perhaps we can arrive at some kind of accord, beloved,” Ystin interjected, placing a hand on Deirdre’s shoulder. “I understand how jarring seeing this knave must be, but our comrades in arms are lost to time. Other priorities must take precedence.”
Sighing deeply, Deirdre fell back into the chair behind her, irked that this modified timeline removed all the progress she’d made in molding the chair to fit her form. She could see Liri wince at the force she had used to enter the chair, and felt a little bad about that.
God, she could be selfish sometimes.
“Fine. Fine, I’ll be a good sheila now. What is your plan, oh fearless brother o’ mine?” She felt the tension in the room let up slightly, and Ystin gave her a grateful smile.
Owen pulled out another boomerang of his and started pressing the buttons on it. A projection appeared, seemingly the timeline they were currently in. Biting back her instincts to make fun of her brother’s projecto-rang, she sat back and listened as he began to point at the timeline. “As you can see, this is the current stream that we’re in. You can see these discolorations,” he explained, pointing at the shades of red appearing in the mostly blue timeline, “that indicate the anomalies you’re normally after. Sure, they aren’t the best thing to have appear, but it’s within the Time Masters’ range of acceptable aberrations. From what Deirdre is saying, the kind of anomaly we’re looking for with this situation, with one team seemingly erased from time and another fully resurrected, should be lighting this up like a Christmas tree. That massive of a ripple effect from those changes would unmoor us into the Bleed, never to return.”
“But we’re clearly still here,” Rip Hunter said, scowling. “So you’re saying she’s full of it.”
“Not necessarily,” Owen replied, and Deirdre felt a slight pang in her chest as her brother came to her defense. He dialed in another setting and another hologram appeared, this time showing various circles floating around the timestream. “What do you know about time bubbles?”
Michael raised his hand, ever the teacher’s pet, apparently. “They’re basically pocket dimensions separated out from the timestream. The Time Masters use them sometimes to isolate threats to the stream or conduct experiments.”
“Gold star to you,” Owen said, and Deirdre rolled her eyes as Michael beamed. She missed Booster so much. “Yes, exactly that. So let’s say that these bubbles,” he circled a majority of them, “were made and accounted for. We’re left with a good dozen unsanctioned by the Time Masters.”
Deirdre’s hopes started to pick up before Rip dashed them. “But that’s also within parameters for a timestream. Nature abhors a vacuum and makes time bubbles naturally to fill in any blank spaces that appear. You’re grasping at straws.”
Owen turned toward the captain of the Waverider. “I’m sorry, did you want to run this presentation? I can go back to the Authority and leave y’all to your issues if you want.”
Before Rip could respond, Liri stepped in. “Rip, let the poor boy explain. You’re being an asshole.”
Deirdre blinked, surprised at Liri’s interjection. The AI she knew would never put the captain in his place like that. And even more shocking, she saw Rip pull back and motion for Owen to continue, clearly chastened by his crewmate.
Miracles did happen.
“You’re correct, the other bubbles not highlighted are indeed naturally occurring.” Owen pointed at them and expanded them. “But someone with enough access and know-how can commandeer these time bubbles and manipulate them for their own uses.”
Matthew Rider raised his hand. “So you’re saying our missing people could be inside these bubbles? But what about the damage to the timeline from removing them in the first place?”
“Good question. Like I said, this level of fuckery to the order of things should’ve made things completely unravel. That being said, it is possible for someone with a high degree of chronal knowledge and access to do it. It’d be damn risky, as one mistake could spell disaster. But… it's becoming more and more evident that whatever’s responsible for this isn’t an amateur.” Owen pulled up a blank file now, a glaring DATA NOT FOUND flashing in front of them. “You say you all saw Walker Gabriel vanish, and still have memories of him. He’s not in our databases anymore, and there’s not even a void left behind where he should be. This thing took him out and plastered over the timestream to remove any trace.”
Silence fell on the group as the idea of what they were up against sunk in. Deirdre pondered who or what could hate them enough to do something like this.
“So what’re our next steps?” Liri asked, typing away furiously at her datapad. “Should we search these time bubbles for our missing teammates?”
Deirdre smiled sadly as she heard Liri refer to her friends as teammates. This version didn’t even know these people, didn’t have any definitive proof that they even existed, and yet she took them in her heart as part of the team.
Owen shook his head. “That would take too long, and might tip off whatever’s doing this to our plan. We need more manpower for the search and a way to narrow down the field.” Roxy Rocket, who’d spent the entire conversation vlogging the control room with her camera, piped in. “Sciency stuff isn’t really my bag, but could you maybe look for people that interacted with these folks and trace them that way? Use their memories to bridge the gap or whatever?”
To Deirdre, it sounded like the kind of stupid thing that just might work. “I know someone that might be able to help us with that, and I can get some people together we could use.”
Something was wrong, of that Violet was certain.
Their journey had led them across the globe when they’d felt it happen, felt the universe attempting to steal another memory from them. Violet fought against the overwhelming vibrations that tried to steal the memory of their friend from them, using their powers to shield their mind and their heart. It took everything they had, rendering Violet unconscious for a day. But when they awoke, they still remembered Michael Jon Carter, Booster Gold. The first person in Violet’s memory that tried to help them.
It felt fitting, going from trying to discover their past to helping bring their friend back from oblivion.
The problem was, nothing was working.
“I’m sorry, I don’t know what you’re talking about,” Daniel Carter asserted, shifting on his crutches as he tried to close the door on Violet. They held their hand out to stop it, and felt fear trickle through Daniel’s aura.
“I do not mean to startle you, I am just trying to find some answers,” Violet explained, backing away from the door to give Daniel some space. “I know it sounds strange, but I am telling you only the truth.”
“Look, I wish you luck in… this whole thing you’ve got going,” Daniel said, “but I don’t have a clue about any future relatives of mine, whatever the hell that means. Now if you’ll excuse me, I need to get ready for a job interview.”
This time, Violet allowed him to slam the door in their face. It was no use. It seemed anyone they’d attempted to contact didn’t have any memories of their friend. Violet knew that if they could only use their aura to show Daniel the true way of things…
But no. That would be a trespass they were hesitant to employ. There had to be a way to bring Michael back without hurting anyone. They would find it, they were sure of it. “Well, if it isn’t the most colorful person I know,” a familiar voice said from behind them. Violet turned around to see Deirdre Harkness approaching them from across the street. Unconsciously adjusting their hijab, Violet ran towards their former teammate and enveloped her in a tight hug.
“You are truly a sight for sore eyes, Deirdre,” Violet said, tears running down their face as they took in their old friend’s presence. “I could really use a friendly ear at the moment. I feel as if I have gone insane.”
Deirdre pulled back from the hug to look Violet in the eye. After a moment of searching, she smiled. “You remember, don’t you?”
Violet’s eyes widened in shock and joy. “Tell me you are not humoring me. You truly remember our friend?”
A wave of relief washed over Violet, and it was all they could do to keep their aura in check as Deirdre spoke. “Not only do I remember Booster and Rip and the others, but I think I have a way to get them back.”
Living in a mansion wasn’t all it was cracked up to be. For instance, the amount of upkeep required to keep it from becoming a dusty mountain of sadness was just completely unrealistic for one person to do. That meant hiring people to help maintain the grounds, sweep the floors, clean the bathrooms and bedrooms.
Mitch Shelley was not a fan of people.
“No, I said not to make the topiary look like a Soder Cola can,” Mitch insisted to his groundskeeper, an older man whose proximity to loud saws all his life made him hard of hearing. “It looks corny as fuck.”
The old man shook his head. “I think it looks fine, sir. Plus I know your corporate sponsors will appreciate it for that gala you’re holding next week.”
Goddammit. Mitch had been dreading that stupid party ever since he’d been asked to host it in honor of his latest sponsorship campaign for the Soder Cola company. Sure, he wasn’t too involved with the planning (at least, when he could dodge the phone calls and house visits of the party planner he’d hired) but it still took up way too much of his time. That wasn’t to mention the fact that he had to attend the thing.
In a suit.
Ugh.
“Maybe you’re right. Thanks, Joe,” Mitch said, handing the groundskeeper a generous tip. Joe was probably the most down-to-earth of his employees, and he wanted to make sure he was taken care of. Joe shook his hand appreciatively and walked out the door, brushing past a red haired woman dressed garishly in some sort of costume.
“You’re a week early for the gala, darlin’,” Mitch said, waving her away as he tried to escape to his theater room. “I’m sure whatever skill you have will be enough to entertain the suits coming to this shindig.”
“Har de har, asshole,” the woman said, her Australian accent giving him pause. What was an Aussie doing in Pennsylvania? “I’m actually here for Resurrection Man. Need his help.”
Mitch sighed, “Look, I’m sure whatever cat’s stuck in a tree will get itself out. If this is about Lazarus, tell that fucker he can come and face me himself rather than sending his new sidekick.”
The woman rolled her eyes. “Look, I know you. You’re a wild horse that can’t be reined in. You need adventure in your life, and I’m here to offer it. Ever time traveled before?”
Mitch stopped on the steps. “In a manner of speaking. What did you have in mind?” Maybe he’d hear this woman out. If anything it might last long enough to get him out of this fucking party.
“Stargazer tipline, how can we help?” Jack Knight was surprised when the old phone line started to ring. Courtney had been right; most people used the app to ask for help.

2024.05.15 19:19 ShinySephiroth Question on Modern Power Girl
I dropped off of following the continuity after Death Metal/Infinite Frontier. I'm trying to catch up and am confused about Power Girl. Here is my understanding:
Golden Age Power Girl was one of the non-Earth-One survivors of CoIE to live on New Earth and (Watsonian, not Doylean) had a spell cast on her causing her to forget her Kryptonian origin until Psycho Pirate repaired her memories for Infinite Crisis. She and the JSA, from the perspective of New Earth (soon to become Earth 0), are eventually given the Wally West treatment by Dr. Manhattan and are scrubbed from existence for his New 52 experiment, post-Flashpoint.
Here's where it gets fun! iirc the last panels of the Convergence event hints that the New 52 Earth 2 heroes are the "reincarnations" of the pre-Flashpoint JSA so, taking that into account (which now seems to be wrong?), Kara Zor-L was put back on Earth 2 and was its Supergirl until a Boom Tube displaced her and Helena Wayne/Robin onto Earth 0 (main New 52 Earth). They have their adventures there, becoming Power Girl and Huntress respectively, before eventually returning to Earth 2 (leaving Tanya Spears and Helena Bertinelli of Earth 0 to take over those mantles, again respectively). Kara and Helena soon gain a new planet in their Earth 2 universe and seemingly live happily ever after, with Helena Wayne dropping the Huntress alias to become Batman while the comic insinuates that Kara returned to having "Super" in her name due to her updated costume.
Around the time they were wrapping this up Rebirth happened, with Wally West returning and slowly beginning the restoration of pre-Flashpoint memories and revealing that Earth 0 is actually a manipulated New Earth (with events like Superman Reborn and Milk Wars further warping this universe, inching it more and more to be like it was pre-New 52). During this time, Deathstroke created a short-lived Teen Titans alternative team (Defiance) that included Tanya Spears. The last issue of this team showed Tanya getting her consciousness stuck in another plane of existence with... a Kara/Power Girl. Perplexingly, she is wearing her pre-Flashpoint costume but the two seem to recognize each other.
All versions of Power Girl are then in limbo until Doomsday Clock. Dr. Manhattan during this arc is shown the light by Superman's goodness and undoes the final pieces of his universe manipulation, restoring the JSA... including Kara (I did not remember Huntress being in the mix). This leads the reader (at least me) to wonder if this is a return of the pre-Flashpoint Power Girl, or if these are the New 52 Earth 2 heroes placed "back" on Earth 0 with their "real" identities restored. This latter interpretation is an attempt to bring in that Convergence panel mentioned earlier, but as I write this I recall how Jay Garrick was able to burst through the Speed Force during "The Button" to try and anchor himself back on Earth 0/New Earth (though it doesn't work). This seems to be strong evidence that pre-Flashpoint Jay Garrick and New 52 Jay Garrick are, indeed, two different people and that the Convergence panel was either stating they are "in spirit" the reincarnations of their former selves, or they misunderstood what Geoff Johns had planned, or things changed behind the scenes (leaning toward the latter).
For Kara, this is heavily insinuates to me that the Doomsday Clock version of her is the actual pre-Flashpoint version and that her New 52 Earth 2 counterpart is just a separate "variant". The Kara from Doomsday Clock is then thrust into action during various events, including Infinite Frontier & Dark Crisis. This leads to her... interesting... interpretation (from what I've seen so far) in Dawn of DC that acknowledges her entire story arc pre-Flashpoint... but then has her acting more like Cartoon Network Starfire, sooo...?
I haven't gotten this far yet in the readings - apparently Dawn of DC Power Girl meets a Helena Wayne for Johns' JSA revival... For those who have read this, due to this Helena being from a potential future timeline, this is not the same Helena Wayne from New 52 Earth 2, correct? I can only guess that those versions are still out there because I heard that New 52 Earth 2 Val Zod appears in an early Dawn of DC Superman issue, so this causes me more confusion because Dawn of DC Power Girl #1 states that Kara Zor-L's current origin maintains her status being from Earth 2... does this mean there are two Earth 2s now?
I'm guessing they haven't directly addressed this, but I'm reaching out here to see if anyone knows because they've read more issues than someone should and they found hidden hints that help rectify all of this.
Here's a summary of sticking points for me:
1) New 52 Earth 2 Kara seemingly appears in a void wearing her pre-Flashpoint costume even though last we saw her very recently donning a "Super" costume so it is unclear which version of Kara we saw (perhaps Tanya thought it was "her" Kara?)
2) Pre-Flashpoint Kara seemingly returning as a separate character, leaving the status of the 2 other Power Girls shown post-Flashpoint up in the air
3) Evidence points to current Earth 2 still being the one shown in Multiversity and New 52, causing issues with current Power Girl stating she originated on Earth 2... so did they merge the two characters or are there now two Earth 2s?
I know the easy answer is "writers messed up", but I'd like to see if we can either find evidence of them knowing what they're doing or, if not, fancraft an answer.

2024.05.15 18:57 97cweb Magic is Electricity?! Part 20
First < Previous Next >
I snap my head back down, with renewed vigour and hope about communicating with everyone without needing to play charades. With the knowledge that this is a microphone, my mind swims with the possibilities. If they can grow quartz crystals, they may be able to refine and grow silicon crystals, effectively making computers. Getting back on track, I add a resistor above the tremorsense and attach a ground wire below it. Tapping off between the resistor and tremorsense, I look to Silvra and gesture towards the translator.
“And what do you think you are doing?” She remarks, eying the setup with a mix of scepticism and intrigue. Her arms were folded, her brow furrowed in concentration.
“Just because you may be able to overhaul our entire way of life, does not mean I will give you something worth half a year’s wage. You best get to explaining yourself.”
Taking a deep breath, I sketched a quick diagram on the paper between us. I outlined how the piezoelectric effect of the tremorsense could convert sound into electrical signals that the translator could interpret. “It’s like turning vibrations into voices,” I explained, hoping the simplicity of the analogy would bridge the gap my technical terms could not.
“It…should work. Why has no one thought of this before?!” Silvra asks eagerly, reaching for even more paper, with Thallion leaning in to take notes as we possibly cross the language barrier.
Silvra passes me the translator, and carefully I place the tap wire on the central nub, and the ground on the body, similar to how their hands work with the metallic pin and the rest of their hand. I then reach for my phone and attach the power to the resistor, and the ground to the body of the translator as well.
I speak.
“can you hear me?” I ask, apprehensively, hoping I did not just blow up the device. It’s faint whine either being a really good thing, or a very bad thing.
“What was that?!” Lena turns around, after staring off into space as we got technical.
“i said, can you hear me?”
“yes we can!” Lena exclaims, not through the device, but from across the table, her eyes wide with astonishment.
“I can too. it is a little dull, but we can hear you. and you can hear us! without us touching it!” Thallion remarks,
I notice that yes, I can hear them, but rather than being melodic and transferring all the intent behind the meaning of the word, translating the emphasis, it comes across as dull, flat and lifeless, like text to speech readers. I find it quite painful to listen to.
“Perhaps it's a minor calibration issue,” I suggested, already thinking about adjustments to enhance the voice modulation.
“maybe i can sound like a robot for now, but perhaps, you should continue playing hot potato with the translator?”
“forget that!” Silvra remarks. “i may sound flat, but i don’t have to pass the device around! i can just leave it on a desk somewhere and it will just work!”
“not only is this an overhaul in this device, but think of the implications. we can talk across species without needing to touch very complex systems. we may even be able to communicate with animals, Lena!”
Lena perks up at this, “if i could talk to them, then i may be able to convince the big ones to leave us alone, but I worry about what that means if they are truly intelligent.”
Looking back at the device, I think back to the little I remember for analog electronics. The device can pass emotion and translate it, so it is capable of doing so. Maybe there is an issue with the prefilter? I could possibly fix that.
“silvra, it is amazing that we can talk, but I find it painful to listen to all of you due to the robotic voice. i think i can fix it. do you have the schematics for the device?”
“i don’t know what robot is, but i am guessing the flat sound, i do have drawings, let me go get them”
Silvra heads out, and Tallion is writing down everything. Lena is leaning over his shoulder.
“i know you are upset, but what you did is monumental, communication without contact, translation without touch. just remember that you are using your phone for power!” Lena states. I cannot tell emotion but bittersweet is all I can get.
Silvra enters again, knocking the snow off her clothes carrying some yellowed paper. Placing them down before me, I look across them.
“maybe increase the power input? That usually works for us. More space for clarity, or something,” Thallion adds, trying to be helpful.
I shake my head no, trying to ignore what he just said, based on the fact that is how humanity killed the first transatlantic cables. It is not a power issue as the device turns on, but a warping or nonlinearity of the data itself.
After a few moments of staring at the schematics, I find the input and the first thing I see is the massive choke directly after the input.
“a ha! found it!” I exclaim, reaching for the toolkit that Silvra brought over a few days ago. “just need to remove the choke at the front!”
“before you go voiding the warranty on this, why would that solve anything? that is how we regulate the flow of power!”
“i make direct current from my phone, so i don’t need to regulate it, in fact, that choke is destroying all high frequencies. i will talk about it if this works.”
“ok, but i’ll dismantle it. just point out the part on the schematic, and provide a jumper to cross over the holes”
Sighing, I grab the cables from the toolbox, along with the soldering iron and candle. Silvra grabs the components from me, and carefully unscrews the ground bell from around the power pin. Finding the power pin’s input into the interior, there is a large coil. Silvra quickly removes the coil and puts the jumper in its place.
Reassembling it, she gestures for me to talk. Taking a deep breath, and reconnecting my phone, I talk.
“Good afternoon everyone! And welcome to a new era! One of power for all!”
“I can hear you loud and clear!” Silvra exclaims, jumping up from the table.
“Astounding! Decoding the schematic and removing the choke did solve the problem!” Thallion replies.
“It worked before, and now it works better, I still think the first is more important to document”, Lena interjects, clearly getting bored of all of this tech talk
“So, Silvra,” I mention, “removing the choke works due to the same way the coil of wire moves coins: magnetism. Over the next few days we’ll be going over this in a lot more detail, but the choke does not choke the current, it converts it into magnetism, which is then released later. A changing current results in a changing magnet inside. It is very weak but enough to smooth input ripples, and stretch out the input spike slightly, which is probably why it is there in the first place.”
“But it comes with a downside. It acts stronger on faster switching pulses than on slow ones. My dc power has only an on pulse, but the signal of my voice is made of many higher vibrations. The choke would have killed this high frequency, and would have only passed the lower, which would be the fundamental frequencies only, sounding flat. The translator would then only be able to act on this flattened signal.”
“Now, I only got about half of that, but it stores the current as something called magnetism, saving it for later, and smoothing out the input,” Thallion states, looking up from his notes.
“Exactly. Think of it like a dam. Takes the surges and smooths them out, but you lose the changes caused by individual rainfalls”
“So what exactly is magnetism?”
“That is a good question, and contains several fields, chemistry, physics, all of what we classify as science. It will look like magic to you, but any sufficiently advanced magic is indistinguishable from science. Just be ready to learn.
“Does this make the motor thing spin?” Lena asks.
“Yes, yes it does.” I reply, looking at my phone and the power slowly but steadily dropping.

I snap my head back down, with renewed vigour and hope about communicating with everyone without needing to play charades. With the knowledge that this is a microphone, my mind swims with the possibilities. If they can grow quartz crystals, they may be able to refine and grow silicon crystals, effectively making computers. Getting back on track, I add a resistor above the tremorsense and attach a ground wire below it. Tapping off between the resistor and tremorsense, I look to Silvra and gesture towards the translator.
“And what do you think you are doing?” She remarks, eying the setup with a mix of scepticism and intrigue. Her arms were folded, her brow furrowed in concentration.
“Just because you may be able to overhaul our entire way of life, does not mean I will give you something worth half a year’s wage. You best get to explaining yourself.”
Taking a deep breath, I sketched a quick diagram on the paper between us. I outlined how the piezoelectric effect of the tremorsense could convert sound into electrical signals that the translator could interpret. “It’s like turning vibrations into voices,” I explained, hoping the simplicity of the analogy would bridge the gap my technical terms could not.
“It…should work. Why has no one thought of this before?!” Silvra asks eagerly, reaching for even more paper, with Thallion leaning in to take notes as we possibly cross the language barrier.
Silvra passes me the translator, and carefully I place the tap wire on the central nub, and the ground on the body, similar to how their hands work with the metallic pin and the rest of their hand. I then reach for my phone and attach the power to the resistor, and the ground to the body of the translator as well.
I speak.
“can you hear me?” I ask, apprehensively, hoping I did not just blow up the device. It’s faint whine either being a really good thing, or a very bad thing.
“What was that?!” Lena turns around, after staring off into space as we got technical.
“i said, can you hear me?”
“yes we can!” Lena exclaims, not through the device, but from across the table, her eyes wide with astonishment.
“I can too. it is a little dull, but we can hear you. and you can hear us! without us touching it!” Thallion remarks,
I notice that yes, I can hear them, but rather than being melodic and transferring all the intent behind the meaning of the word, translating the emphasis, it comes across as dull, flat and lifeless, like text to speech readers. I find it quite painful to listen to.
“Perhaps it's a minor calibration issue,” I suggested, already thinking about adjustments to enhance the voice modulation.
“maybe i can sound like a robot for now, but perhaps, you should continue playing hot potato with the translator?”
“forget that!” Silvra remarks. “i may sound flat, but i don’t have to pass the device around! i can just leave it on a desk somewhere and it will just work!”
“not only is this an overhaul in this device, but think of the implications. we can talk across species without needing to touch very complex systems. we may even be able to communicate with animals, Lena!”
Lena perks up at this, “if i could talk to them, then i may be able to convince the big ones to leave us alone, but I worry about what that means if they are truly intelligent.”
Looking back at the device, I think back to the little I remember for analog electronics. The device can pass emotion and translate it, so it is capable of doing so. Maybe there is an issue with the prefilter? I could possibly fix that.
“silvra, it is amazing that we can talk, but I find it painful to listen to all of you due to the robotic voice. i think i can fix it. do you have the schematics for the device?”
“i don’t know what robot is, but i am guessing the flat sound, i do have drawings, let me go get them”
Silvra heads out, and Tallion is writing down everything. Lena is leaning over his shoulder.
“i know you are upset, but what you did is monumental, communication without contact, translation without touch. just remember that you are using your phone for power!” Lena states. I cannot tell emotion but bittersweet is all I can get.
Silvra enters again, knocking the snow off her clothes carrying some yellowed paper. Placing them down before me, I look across them.
“maybe increase the power input? That usually works for us. More space for clarity, or something,” Thallion adds, trying to be helpful.
I shake my head no, trying to ignore what he just said, based on the fact that is how humanity killed the first transatlantic cables. It is not a power issue as the device turns on, but a warping or nonlinearity of the data itself.
After a few moments of staring at the schematics, I find the input and the first thing I see is the massive choke directly after the input.
“a ha! found it!” I exclaim, reaching for the toolkit that Silvra brought over a few days ago. “just need to remove the choke at the front!”
“before you go voiding the warranty on this, why would that solve anything? that is how we regulate the flow of power!”
“i make direct current from my phone, so i don’t need to regulate it, in fact, that choke is destroying all high frequencies. i will talk about it if this works.”
“ok, but i’ll dismantle it. just point out the part on the schematic, and provide a jumper to cross over the holes”
Sighing, I grab the cables from the toolbox, along with the soldering iron and candle. Silvra grabs the components from me, and carefully unscrews the ground bell from around the power pin. Finding the power pin’s input into the interior, there is a large coil. Silvra quickly removes the coil and puts the jumper in its place.
Reassembling it, she gestures for me to talk. Taking a deep breath, and reconnecting my phone, I talk.
“Good afternoon everyone! And welcome to a new era! One of power for all!”
“I can hear you loud and clear!” Silvra exclaims, jumping up from the table.
“Astounding! Decoding the schematic and removing the choke did solve the problem!” Thallion replies.
“It worked before, and now it works better, I still think the first is more important to document”, Lena interjects, clearly getting bored of all of this tech talk
“So, Silvra,” I mention, “removing the choke works due to the same way the coil of wire moves coins: magnetism.

2024.05.15 18:03 _zeez_ Low EMI PCB Design: Review Request
 | Hello everyone, so for a project of mine I designed a PCB that consists of 3 DC DC cpnverters (28VDC to 12VDC, 28VDC to 5VDC, ) 2 GPIO expanders (SPI), 3 Dual motor drivers, 3 current monitors (I2C), 3 load switches (to turn on heaters) and an IMU (I2C). submitted by _zeez_ to PrintedCircuitBoard [link] [comments] All of these are connected to a Raspberry Pi which communicates with the PCB using both SPI and I2C. The layer stackup is as follows: 4 layers: Top layer : GND - Red Middle layer (Inner 1) : Signal / Power - Green Middle layer (Inner 2) : Signal / Power - Yellow Bottom layer : GND - Blue I have added TVS diodes for protection againt Electrostatic Discharge. As the board needs to be designed for Low EMI, I added an EMI filter (consisting of a ferrte bead, capacitors and a resistor) at the outputs of the DCDC converters, the design was based on a recommendation found here: https://www.analog.com/media/en/technical-documentation/application-notes/AN-1368.pdf If anyone has worked on PCBs where ESD protection using TVS diodes is implemented, or on PCBs that should have a low EMI signature, I would be really grateful for your advice. As I have designed PCBs before but not really a board with scrict EMI limitations, I would be grateful if you could have a look and give me some suggestions and recommendations to improve the design. I am not really sure about my approach regarding the EMI Filter, if it really is beneficial or not. The link to the repository with the entire project can be found here: https://github.com/ber2rv/fluidic Thank you!

2024.05.15 17:18 ddovod Cetus X hardware + bigger battery + custom frame = 14+ minutes cruising. I know you guys like 3d printed frames
 | TL;DR I've put Cetus X hardware + lollipop antenna + 850mah 2s battery into custom designed and 3d printed frame (carbon fiber reinforced PP) and got 14.5 minutes cruising time indoor. Will try to push it harder outside and will try 3-blade props later, waiting for the weekend. P.S.: The last image contains a bit outdated canopy design. submitted by ddovod to fpv [link] [comments] Long story. Newer Cetus X revision has pretty decent hardware for 2 inch drone (F4 2S 15A V1.0, not available for purchase separately). I've got 2 and decided to rework one of them. The main idea behind this build was to move the center of mass closer to the props plane to make it more efficient and responsive. Plus we can save a few grams by making it a toothpick style and removing ducts. Eventually after designing and printing a dozen of frames and trying different materials I came up with this design (I'll post all models later, I need a bit more tests). Btw you can still change the camera angle. The frame itself is 14 grams lighter than the original one, it bends kinda same as the original so the stiffness is very close, and I've also added XT30 plug, capacitor and lollipop antenna to it. It also has a mounting place for Runcam Thumb Pro W which also has a new lightweight housing. Some findings on materials. PLA is great, it's stiff, easy to print. But it has bad layer adhesion, heat resistance, and it's brittle. But the main concern here is its' density which is around 1.3 g/cm3. PETG is great, easy to print, not as stiff as PLA, but stiff enough. It has great layer adhesion, decent heat resistance, it's not brittle. Its density is a bit smaller than PLA, around 1.25 g/cm3. PC-ABS blend is awesome though it's harder to print than the previous two. It's as stiff as PLA (probably more stiff), great heat resistance, but its layer adhesion is on par with PLA. Also it's more brittle than PETG, but less than PLA. Also its density is around 1.15. This was my choice until I decided to try PP. PP is weird. It's very hard to print, it's not stiff at all. But it has excellent layer adhesion, even better than PETG, it's not brittle at all because it's too soft, BUT its density is around 0.75 g/cm3. The fact that it's 1/3 times lighter than the PC-ABS bothered me too much so I started to look further. And finally PP CF17 (17% carbon fiber infill). It's still very hard to print, the PP doesn't stick to anything except PP, and it has huge shrink. But it's stiffness is just a bit smaller than PETG (though still as stiff as the original frame), good layer adhesion (on par with PETG), great heat resistance, and it's still not brittle at all. From my calculation its density is arount 0.78 g/cm3. Other tech details. I've separated the camera and vtx and connected them with wires. Also I've soldered 25V 220uf capacitor in parallel with power lines. Apart from that I've soldered additional power line from the battery to power the Runcam Thumb Pro W camera. The idea is to use tiny switching DC-DC step-down converter powered directly by the battery, so far it works fine and it's no need to solder directly to the FC (I still cannot find the schematics of this FC, BetaFPV cannot give me one since this FC is not sold separately). It will deliver 5V 0.7A when the supply is 6.5v+ (at least they state so), but from my measurement this camera consumes around 300ma when shooting 2.7@60fps. Weight. Original Cetus X dry - 55.5g This drone dry - 46.2g 2 original batteries (BetaFPV 450mah x2) - 25.4g GNB 850mah 2s - 36.6g Runcam Thumb Pro W with custom housing, microsd and DC-DC converter - 15.5g So as you can see the original setup with 2x450mah batteries is around 81g. The new setup with 2s 850mah battery is around 83g. The new setup with 2s 850mah battery and Runcam camera is around 98g. Flight time. I've only tried indoor cruising flight so far. With GNB 2s 850mah it flies 14.5 minutes (disarm at 7V, it rebounds to 7.2V so I guess there's 30-40secs more if you drain it until it rebounds to 7V). If I add the camera and shoot 2.7k@60fps it flies 9.5 minutes under the same conditions. Any feedback is appreciated = ) |

It's still very hard to print, the PP doesn't stick to anything except PP, and it has huge shrink. But it's stiffness is just a bit smaller than PETG (though still as stiff as the original frame), good layer adhesion (on par with PETG), great heat resistance, and it's still not brittle at all. From my calculation its density is arount 0.78 g/cm3. Other tech details. I've separated the camera and vtx and connected them with wires. Also I've soldered 25V 220uf capacitor in parallel with power lines. Apart from that I've soldered additional power line from the battery to power the Runcam Thumb Pro W camera. The idea is to use tiny switching DC-DC step-down converter powered directly by the battery, so far it works fine and it's no need to solder directly to the FC (I still cannot find the schematics of this FC, BetaFPV cannot give me one since this FC is not sold separately). It will deliver 5V 0.7A when the supply is 6.5v+ (at least they state so), but from my measurement this camera consumes around 300ma when shooting 2.7@60fps. Weight. Original Cetus X dry - 55.5g This drone dry - 46.2g 2 original batteries (BetaFPV 450mah x2) - 25.4g GNB 850mah 2s - 36.6g Runcam Thumb Pro W with custom housing, microsd, ND filter and and DC-DC converter - 15.5g So as you can see the original setup with 2x450mah batteries is around 81g. The new setup with 2s 850mah battery is around 83g. The new setup with 2s 850mah battery and Runcam camera is around 98g. Flight time. I've only tried indoor cruising flight so far. With GNB 2s 850mah it flies 14.5 minutes (disarm at 7V, it rebounds to 7.2V so I guess there're 30-40secs more if you drain it until it rebounds to 7V). If I add the camera and shoot 2.7k@60fps it flies 9.5 minutes under the same conditions. Any feedback would be appreciated = ) |
2024.05.15 15:23 ncssrtnvnthm Silicon diode between gate and source of an n-ch mosfet
 | I came across with a very common PWM motor control circuit which is used to speed control dc motors with pwm signal. The module uses d4184 n-channel mosfet to do the job. I searched for the schematic of this module and most of it is easy and self explaining. Only thing I don't understand is the diode (circled with red on the picture) between the gate and the source of the mosfet. If ESP protection is the goal then i think it would be a TVS or Zener diode instead. Whats the purpose of this diode and why is it inserted in the circuit that way (anode terminal of the diode connected to the source of the mosfet)? submitted by ncssrtnvnthm to AskElectronics [link] [comments] https://preview.redd.it/b3ihpqik9l0d1.png?width=792&format=png&auto=webp&s=8349fabb0d2d04f1357b3140752ea3dad9ae076e |
2024.05.15 12:45 jjnfsk Issues with Renogy charge controller
 | Hi all, searching for some assistance/advice here. submitted by jjnfsk to VanLife [link] [comments] I recently purchased a converted van with a renogy charge controller. The van has a solar panel (unsure of wattage). It has two lead-acid house batteries totalling 225Ah. The starter battery is a brand new 95Ah unit. The solar panel is showing between 15-20V (confirmed with a voltmeter) but is producing virtually no current, either 0 or 0.01A. The starter battery is brand new as I said and produces around 14.2/3V, but again, the renogy unit is only receiving between 0-0.02A. The above screenshot is from the DC Home app whilst the van is running. Why is the charge controller, and thus house battery, receiving such a miniscule amount of current? What can I do to rectify this? Thank you, I appreciate any feedback and can provide additional photos/videos if needs be! |
2024.05.13 17:00 thatotherchicka April 2021 - Question #30
“30. What is the CLASSIFICATION of a power supply that is described as a 100-Watt medical grade power supply for use with a Portable Oxygen Concentrator (POC)? The power supply is a rectifying power supply and functions to convert input AC input voltage to 29 VDC electrical output that is supplied directly to the POC. The power supply is said to provide power exclusively to a POC and is permanently embossed stating its limited use as a medical AC/DC Adapter for a POC.
A. 8504.40.6007
B. 8504.40.8500
C. 8504.40.9520
D. 8504.40.9530
E. 9019.20.0000”
Ok, let’s start with our headings on this one.
8504 - Electrical transformers, static converters (for example, rectifiers) and inductors; parts thereof:
9019 - Mechano-therapy appliances; massage apparatus; psychological aptitude-testing apparatus; ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus; parts and accessories thereof:
Let’s first see if we can remove 9019 from the running. See chapter note 2(a):
2. Subject to note 1 above, parts and accessories for machines, apparatus, instruments or articles of this chapter are to be classified according to the following rules:
(a) Parts and accessories which are goods included in any of the headings of this chapter or of chapter 84, 85 or 91 (other than heading 8487, 8548 or 9033) are in all cases to be classified in their respective headings;
That tells me that we should not classify articles of 85 as parts or accessories under the 9019 provision. Let’s toss that out. Now, let’s look at our potential HTS codes since they all fall within the same subheading:
8504.40.6007 - Power supplies for automatic data processing machines or units thereof of heading 8471; power supplies for goods of subheading 8443.31 or 8443.32; power supplies for monitors of subheading 8528.42 or 8528.52 or projectors of subheading 8528.62: Suitable for physical incorporation into automatic data processing machines or units thereof of heading 8471
8504.40.8500 - For telecommunication apparatus
8504.40.9520 – Other: Rectifiers and rectifying apparatus: Power Supplies: With a power output exceeding 50 W but not exceeding 150 W
8504.40.9530 - Other: Rectifiers and rectifying apparatus: Power Supplies: With a power output exceeding 150 W but not exceeding 500 W
Our power supply is not for any of the items listed in 8504.40.6007. So it wouldn’t be classified there. This isn’t for a telecommunication apparatus so it wouldn’t go under 8504.40.8500. That just leaves the 8504.40.95 provisions. Ours is 100 watt. That would place it under 8504.40.9520. The answer is C.

2024.05.12 15:52 mashockie HermanMiller Nevi Desk & LogicData SmartNeo Controller Repair
My company (I work for a biotech company as their in-house lab engineer) moved into a new building last year. The office area is outfitted with ~100 HermanMiller Nevi sit-stand desks. They were working fine last year and then this year I started getting a couple complaints from colleagues that they weren't working properly (I am not a facilities manager, but my colleagues know I will try to fix anything and like to help out with this kind of stuff when I can). The HermanMiller Nevi is outfitted with a LogicData SMARTneo controller that drives two Bosch brushed DC motors within each desk leg. There is also a switch with two buttons (for up and down) available to the user to control the desk. The controller is powered via AC two prong power cord.
The two complaints I got were that the desk would only work in the down position, but not up. I took a closer look at one of the controllers and I couldn't find anything wrong with it. My only conclusion was that there was something wrong with the microcontroller. I tried to flash it so I could potentially replace it, but it is read-protected.
But I was not quite satisfied with that conclusion, so I decided to take a closer look at it again. I took a known working controller from an unoccupied desk to compare it. I kid you not, just the act of plugging in the AC power cord caused the same fault to start occurring in this controller!!! (at least that is what I suspected). The controller has no mains power switch so as soon as you plug it in, it turns on. I don't like this kind of design.
I mapped out the circuit and drew a schematic of the drive circuitry for the motors. I was sure I found how the controller was reversing the polarity of the voltage across the motor to change its direction. So I decided to remove a component (a 1k resistor) from this circuit to test this theory. And sure enough, the controller started working only in the up direction now, but not down! I then put the resistor back and it started working normally again!!! I then performed this same repair to the original controller and it worked again! So there might be a potential resolution to this strange fault? Only time will tell how long it works for (I tested it through several power cycles and still works). Maybe it is due to poor programming of the microcontroller by the manufacturer? I'm not sure. But just thought some of you might find this interesting.
I have a YouTube channel where I posted two videos on this repair:
Part 1 https://www.youtube.com/watch?v=C25SXKfC8Io&t=187s
Part 2 https://www.youtube.com/watch?v=ZLb9rDgd_Jg&t=1293s

2024.05.11 19:42 Rude-Collar-955 The Cheetah for MultiVersus? Hear me out...
 | https://preview.redd.it/08idvrsg2uzc1.jpg?width=568&format=pjpg&auto=webp&s=7f954ad262095d14622ae8a4d5aa76aae8662174 submitted by Rude-Collar-955 to MultiVersus [link] [comments] So, I've been thinking about how Wonder Woman often feels like the most shafted of DC's big 3, compared to Batman and Superman; She didn't get her own animated series, took the longest of them to get movies about her, and just generally doesn't tend to get as much representation compared to them. I was thinking about how MultiVersus could potentially rectify this, and I thought one way would be for them to eventually have an "anti-Big 3" lineup in the game's roster down the line. We obviously just got Joker revealed to parallel Batman, and I think it's highly likely we'll see one of Superman's rogues added at some point, most likely Lex with the new movie imo. So I think rounding that out with one of Wonder Woman's enemies would be neat to see, and Cheetah definitely seems like the best option for that. She's the closest thing she has to an outright nemesis, not counting Greek gods like Ares. I know DC already runs the risk of being oversaturated, and I don't think Cheetah's a top priority compared to characters like Flash or Green Lantern or whatnot, but I also think that would make her a more unexpected and "fresh" pick if that makes any sense. Plus it's easy to envision a moveset for her, just giving her a lot of wild cat style attacks and claw swipes to overwhelm opponents with. Dunno if she's a character the devs are considering or one that'd bring in much hype, just had these thoughts and wanted to share them. |
