LT317AT, LT337AT Cadj help

2024.05.14 13:33 Darkmatter36 LT317AT, LT337AT Cadj help

LT317AT, LT337AT Cadj help
First time tackling a component rebuild and I'm replacing vregs, caps, opamps, etc. Adcom GDA-700 from 1995
I did my research but this last piece stumps me. If I could draw your attention to C115 and C116 in the center. These are, at least I think, the two Cadj capacitors for the LT317/337 in the circuit. They are currently tiny 0.1uf axial mlcc caps just like all the other 0.1uf caps on the board. I'm inclined to replace these with 10uf tantalum because it improves ripple rejection. I'm also replacing the 10uf output caps with 56uf rubycons.
Here's my confusion. The diagram I have states that this is a bipolar capacitor for the Cadj: the picture is all I have to go off. The vishay tantalum caps I bought are not bipolar and I'm not sure if I can use them. I'm unsuccessful in testing the currently installed caps for their polarity so I'm left to trusting the schematic and figuring out the best course of action.
From what I read on the 317/337 data sheet, it seems like the plus side of the capacitor points toward the output for the 317 and on the opposite 337, the minus points toward the output instead. I am new at this and this could very well be common knowledge. I'm also confused as to if the central line running between the two regulators is the ground plane or not.
Any and all help is greatly appreciated 👍

2024.05.14 04:03 Girthilles Small Light Gaming Laptops

Hello All,
Would like some recommendations on a small 10-13" laptop capable of running WoW and Diablo 3-4. Resolution is not really a concern. I'd be happy with the low preset running 60 frames. I don't really play anything new or intensive.
I like this form factor with the type of work I do. Cramped spaces, troubleshooting electronics, reading diagrams/schematics, where my hulking gaming laptop is a good old fashioned PIA.
Any recommendations?

Is this my check fluid transmission bolt or drain plug
Im trying to find the check fluid bolt on my 2012 chevy sonic manual transmission.
Thjs bolt doesn’t look like the drain bolt on the service manual, but the service manual also states “the fluid check bolt at the front of the transmission may not be opened” - what???
I’ve tried to find the schematic diagram but, no luck.
I’d hate to break this bolt loose and drain an my fluid.

2024.05.10 03:00 abysswalker_17th Schematics/diagram of the PS3 Super Slim

Is it available? I'm trying to fix a problem of my Wi-Fi/Bluetooth module. I know for sure, as I tested, that the component which has to function to convert 5 volts into 1.8 it is not working as it should. It is letting pass 2.60 volts. I know that the reparation of that problem involves de-soldering that tiny black square and soldering a 1.8 volts regulator, but I have to know if everything that is AFTER the regulator is okay. I should know if the SMD component I am watching is a capacitor or clog, for example. I should know with how much voltages those SMD components should work with, etcetera.

2024.05.09 23:14 shepherd_29 Power seat question

I have an 87 z31 2+2 with a powered drivers seat and i cannot for the life of me figure out whats wrong with it.
Ive tried looking at the diagrams and schematics in the fsm, but they are a little more complicated than what i can understand.
The previous owner of my z ripped out a lot of "unnecessary" things like the entire ac system, vacuum canister, egr, radiation fan shroud, and probably some other things im unaware of or have forgotten at this very moment.
In the diagrams of the power seat functions, i believe i saw an air pump, and vacuum lines but again dont quote me.
Are the seats electronically controlled, vacuum controlled, or a mixture of both, and if there is supposed to be an air pump for the seats, where would it be located if it hasnt been removed?

2024.05.08 21:48 iamjoel451 Looking for formatting advice

i don't like the bottom, but without some whittling down of information, that's the only way i can think of to get it to one page without crazy formatting or tiny type
Hi all. I'm in an unfortunate situation, and I haven't needed a resume in 10+ years. When i started researching on how stuff was done nowadays, i was amazed with the prevalence of ATS and so on, and it seems like half the advice i got back in the day is now actually counterproductive. As such, i humbly submit my resume to you good folk in an attempt to improve and brainstorm.
Thanks in advance for any feedback.
Background: I was laid off back in '22, and took some time off to help family with some issues. That mess passed, so i need to go back to work. It doesn't help that there is (almost) no demand for the typesetting skills i have in my area. I do have plenty of other skills, especially when it comes to working with my hands. I have a good breadth of experience from my days working with masons and general contractors, as well as getting a roughly 14 week welding course recently. I'd like to get my foot in the door at a machine shop or fabrication place (partly because i like it and partly because i think there should be some jobs in my area), but i haven't gotten any replies from applications submitted through online apps or from the "employment services" agency i'm registered with.
I went with this format because i'm trying to get into this field without direct employment experience, i've done a little related stuff on the side, but never actual welding or machining for pay.
I think part of my issue is the huge recent gap in employment, and i feel like i can make my case better for that in person, so i'm going to just make the rounds, drop off resumes, touch base, and see who i need to talk to if they aren't available. I'll also be taking along lists of references to go with the resumes.

2024.05.08 14:07 LazySnake7 From Under the Ice - Chapter 1

(After finishing NOP1 and reading a few fanfics I've decided to give writing one myself a try! This is my first time posting a fic like this, so please let me know what works and what doesn't. Thanks to SpacePaladin for creating NOP and to my girlfriend for helping me by proofreading this!)

Memory Transcription Subject: Elder Researcher Slira of the Vyr Exploration Initiative
For as long as Vyr have recorded history we have known that the ice above us stretches on forever and that there was nothing beyond. This was truth.
Yet it is in our nature to question impossible truths, for time and currents erode even the most solid foundations. Once we believed the Black Abyss would only ever be certain death to Vyr, and yet now a city sits at its lowest point, admittedly populated by religious madmen who worshipped the greatest horrors any Vyr has ever known.
Still, it was thanks to pioneers like them that I now sat curled up at my desk many kilometres above my home, within the first city ever built atop the ice of Rime, tapping away at a keyboard that commanded a distant drone soaring through the unimaginable void of Space.
To be honest, I was terrified. Flying through space felt like swimming over a deep rift, not knowing what was hiding in the darkness and if it was eyeing me up like some kind of tasty treat. My excitement overpowered my fear however and I chastised myself for humouring ideas better fit for a sci fi novella. A monster wasn’t going to suddenly pop out and eat the drone, the sensors would pick it up long before getting so close. If there even were monsters that swam between the stars looking for things to eat, which seemed unlikely.
As I grabbed a handful of snacks from a packet on my desk my computer beeped angrily at me. A message complaining about an odd energy spike. I huffed in annoyance as I tried to find the source in the sensor data. I swear if this was another ice geyser eruption that got through the exclusion…
Time seemed to slow to a crawl as I noted the strange white object in orbit around our neighbour planet, Turqo. It hadn’t been there a moment ago, and it never appeared on any of the previous scans we did around the planets. Surely we would have noticed it in the three months of studying the odd blue planet with 5 drones, 15 operators always watching the feeds, 100+ scientists studying the data officially and thousands more amateur astro-physicists and casual observers going over our findings every day, right?
No, it had just appeared, loud and blaring energy signatures we barely recognised. I scanned its shape and could come to only one conclusion.
It was a ship. An alien ship.
My colleagues started panicking over the comm channel as they too noticed the sudden appearance.
“What is that?” asked our geologist Dersan. “My drone is picking it up all the way from the surface, what in the abyss…?”
She was interrupted by our astronomer Seshan, voice filled with panic. “Huh? Where did that come from!? Celestial objects don’t just blink into existence!”
The poor dear was very anxious which made it a wonder why he decided to get into astronomy of all things, staring at the great open void all day…
My drone’s sensors pinged as it recognised a new signal coming from the alien ship. It… it’s sending out what were clearly communication signals towards my drone! We were being hailed!
Despite the adrenaline and scattered thoughts running through my mind I quickly set up my workstation for broadcast, making sure everything was still being recorded. First Contact! My mind buzzed with all the possibilities, theories proven and disproven in a mere moment! What would they be like? A small, selfish part of me hoped they liked audio dramas. I shook my head to clear my thoughts, checked to make sure I was presentable (scales all clean!) and established a connection.
A strange white creature appeared on my screen, incredibly fuzzy and with a long thin tail that ended in a puffy ball. They reminded me a bit of a few slugs my brother likes to keep as pets, though I quickly pushed such thoughts away. It wouldn’t do to compare sapient creatures to common animals. Still, something seemed odd to me. Not about the creature itself, but everything around it…
Almost immediately their little black eyes seem to double in size. The alien spoke, seeming a bit agitated at first but then getting progressively calmer as they continued. Suddenly it dawned on me what was so odd about it.
There’s no water! Does this alien not need to breathe?
I did my best to muster my voice and reply. “Sorry, I can’t understand you. Let me try something…”
I sent over a little stream of binary data, a small message to say hello mostly to convey I could hear them. They sent one in response, though I could make no sense of it.
The alien chittered excitedly and clicked away at a keyboard frighteningly similar to my own. His tone becomes slightly agitated, and then soft and… demure? Suddenly my console was awash with data, right before the alien squeaks something and waves a paw. Before I could react the alien ship became a blurry streak and disappeared once more, making me question if what I saw was even real.
However the messages from my colleagues were very real, and so was the data packet on my computer. As a precaution I quarantined it, my mother’s warnings given to me when I was a young pup to never trust data transfers from strangers ringing in my ears. I flicked them with annoyance and took a peak at the gift the alien gave us.
Inside were schematics, blueprint, a lot of files filled with what looked like code and a star chart with some marking on it. I recognised an anatomical diagram of the alien I had just seen, alongside instructions for some kind of chip. It looked like it was meant to be installed at the base of the neck. That along with pictures of strange creatures I didn’t recognise, seemingly talking with each other…
Oh! It’s a translator! I quickly forwarded the packet to my colleagues, the research facility’s main server and to our friends in the engineering department. Despite not knowing their language or even who they are, the aliens have sent us a clear message and the tools needed to solve the former problem!
-][- Fast Forwarding Transcription -][-
It took us a week, but we finally did it! Working together and setting aside all other projects we managed to get a working prototype of the Alien Language Translator working on one of our supercomputers. Technically the program could fit on a far simpler device but I couldn’t resist the urge to be a bit dramatic and almost no one had ever criticised my flair for the theatrical. All that was left was a last-minute test against some of our own languages to make sure it was working properly.
All of Vyrkind was abuzz with the news that alien life was confirmed to exist! Prominent reporters were interviewing any astrophysicists or xenologists they could get their hands on, administrators were discussing expanding our elevator that cut through Rime as well as building new ones and even the Second Church of the Abyss was joining in on the dialogue, even if it was to put forth new weapon designs meant to function in space. “To help put the newly discovered demons of Braru in their place” they explained. At least they were excited about something other than living in absolute darkness, I guess…
I grabbed a snack packet from the facility’s cafeteria and swam as quick as I could to the auditorium. Almost everyone was here, curled up in the seats or huddled up into groups and excitedly discussing what we were about to see.
I picked a seat as close to the front as I could get, eyeing the large screen we had rolled out for the occasion. I opened my packet and couldn’t help but sample some treats before the show began. I didn’t have to wait long before a technician gave the greenlight and the recording of my rather one-sided conversation with the alien played for all to hear.
“An arxur! Get us out…! Wait, their eyes… they aren’t forward facing. Oh! This is a new prey species! Hello?”
“Sorry, I can’t understand you. Let me try something…”
“I’m sorry, I don’t understand… what’s this? Oh, a transmission! That gives me an idea! Here, let me send you instructions on how to make a translator, along with a message for when you finish it.”
“I am Captain Deffin, a member of the Sivkit Grand Herd. Me and my kinsmen were hoping to scout out a small mining venture here, but it seems you already have a site operating in the system, so that gives you a claim over it I imagine. Still, maybe we can come to an arrangement! I’ll be back in [1 month] with some more members of my fleet so we can open diplomatic negotiations!”
“Oh gosh, your ships are so small, you must be even tinier than we are! I don’t know how big your civilization is, but stay away from those stars I marked on the chart! The Sapient Coalition resides there, a horrible farce of an ‘alliance’ created by the evil, meat-eating humans as a way to easier enslave prey like us! So many of our friends lost because they thought they could trust predators…”
They wave their paw
“Farewell friends! Stay safe and stay quiet, we’ll speak again soon!”
The transmission ends, leaving us all in silence.
For a moment the world hangs still, and I swore I heard a bubble pop somewhere. It didn’t last long though, as my colleagues burst into furious dialogue and confused rambling about the implications of the alien’s message.
I myself stayed silent and looked down at my snack packet, proudly branded as “100% genuine Fish Flakes! Free Range!”
Uh oh…

Help needed with DTI HV 550 - High Interlock Resistance (FSAE EV Team)
Has anyone running the DTI HV 550 encountered a high resistance through the interlocks? From our testing (using the kelvin four wire test and an ohmmeter) we measured a resistance of 3.6 ohms across the entire loop. We've previously had luck contacting DTI about other issues, but this time we can't get a good answer from them.

Two batteries so it has to be 24V right? Well that's what the guys in the yard thought. Lumberyard truck with a crane on the back.
Engine started and ran after replacement of a single relay. LUCK!
Now the Instrument Cluster is dead. The warning lights illuminate and the gauges sweep at power on but otherwise nada.
Using a Snappy scanner one time the BCM shows alive the next time dead. Huh, what?
Fried instrument cluster? Start by diagnosing the J1939?
Halp! I'm an auto electrical guy trying to help my heavy diesel buddy who's old school.
Gimme anything other than just mailing the IC off for refurb and praying. Thanks in advance.

2024.05.07 16:12 NoLight5088 Component Sourcing

Component Sourcing
I’m a total newcomer to this. I was trained in basic electronics, reading schematics and diagrams, and troubleshooting, but that was 30 years ago. Now I’m totally lost.
I bought a PCB from General Guitar Gadgets recently, but it did not come with the components. I figured it would be easy enough to follow their BOM and just order the right stuff. But that’s not the case.
For example, what wattage to use for the resistors? I found in this sub that 1/4 Watt may be the way to go. But what about the first diode in this list. When I search on Mouser, there are 41 different varieties of that one number. Then the ICs, the part number listed in the second row is obsolete, but I see several suitable subs, how to pick the right one?
What the heck?!? Am I missing something easy, or do I need to be an electrical engineer to be going down this road?

2024.05.07 15:00 ExilentVacation Captain America and the Avengers (from the ground up)

Hey all!
I'm building from the ground up, as the post says, a Captain America and The Avengers booth from parts. The goal is to have it use old tech with no LCD screen or Raspberry Pi, and be 1:1. I've run into several, to put it lightly, snags. I was hoping this community could point me in the right direction or have the info I'm looking for.
I'm constructing the wooden frame, and I don't know the actual diameters, angles, and side/control profile shape. Does anybody have this info, or at the very least have a cab in the Chicagoland area that I can measure to get the parameters? Also, I have now wiring diagrams or exploded parts view on what all else I need to buy to get this booth up and running.
What I do have is the PCB, decals, Jamma harness, controls, and I think the correct size monitor (but I'll need confirmation on the monitor size) a ton of patience, a hungry mind, and a wallet that can part out the pieces. I have tried the Arcade Museum forum, but that wasn't much help in the ways of wiring schematic and booth diameters.
Any help would be appreciated and if it wasn't flatly stated I want to build this and learn while building rather than buy a used or rebuilt arcade booth. Thanks in advance!

2024.05.07 10:03 NoHayNoticias These pcbs for DIY egs002 based inverters are everywhere, but where are the docs?

These pcbs for DIY egs002 based inverters are everywhere, but where are the docs?
I have stumbled across many Ali sellers carrying these bare Pcbs to build a 12v/24v/48v DC to AC inverter based on the popular egs002 sinewave generating module that goes soldered right in the middle.
Since links are not allowed according to the rules I will let the more experienced reassemble this s_click_aliexpress_com/e/_mMW3GeK
But the sellers provide just the bare pcb. With zero docs, not a diagram, not a parts list. When you ask, you are told "all the parts are listed in the silkscreen printing on the component side, no need for manual".
Yet, reading the buyers comments I see some buyers have managed to assemble them and make them work.
The boards have no model numbers, manufacturer or marking other than "10CMx10CM" (board dimension in cm) etched in the lower-left edge, making it very difficult to find who manufactures these or what design (schematics or part list must be out there somewhere, I'm sure) this pcb belongs too.
After a lot of googling I found other sellers that sell pre-assembled units of this very same board (I found out by noticing the same "10CMx10CM" inscription on one of its edges, and also the two electrolytic caps next to the heatsink).
These go by two different names, but the pcb and specs are the same. You need to search on Ali for
63ha inverter M7df inverter
That's as much as I was able to find. I still think I'm missing a part of the puzzle. There must be a forum thread somewhere describing the pcb, the parts list, and some more in depth description of this project, but I can't find it. Or maybe a manufacturer page in Chinese. H**k I would even take a Chinese language pdf if that's all there is.
One of the reviewers of the bare pcb from ruzzia says something about "Dmitry posted schematics in the wanderer forum". But if course I have no clue what Dmitry or what forum he might be referring to. Perhaps machine translation broke the actual meaning.
I did lots of googling for hours, and this is as much as I was able to find. So I come here to post this, hoping that someone else will say "oh, they meant this forum" and a magic link will be pasted where more information about this board will be available.
Thanks for reading....
