I got my Mobula7 1s about a week ago, and I've spent every waking hour trying to get it to work. I finally got it up and flying and I flew about 40 packs, broke 2 motors off the frame and broke the antenna. I have more screws and a replacement antenna in the mail. It is even more fun than I was expecting.
If I was more weak of heart, I would have given up on the setup process. I am in IT and my job requires a lot of research, trial and error, and tech research. I was following YouTube videos, but so many settings and things have changed on new updates, I wanted to give my exact setup directions so someone like me can find this and see what I did to get mine to work. Looking back I probably spent...15-18 hours trying to get it all right. I set up and re-set up a lot of things.
**Starting out in FPV Takes a LOT of knowledge and setup of equipment. Follow along and watch ALL of the videos, sometimes multiple times. I found myself finding an answer by re-watching and going over the steps multiple times and catching something I'd missed. This is a time commitment, setting up your quad and your radio is going to take A COUPLE OF HOURS AT LEAST! So get comfortable.
Here's what I started with:
Happymodel Mobula7 1s - Analog 0802 20k X12 ELRS
Radiomaster Pocket (I wish now I had started with a Boxer, but I will probably save for a Boxer Max. For $65, the Pocket has been great, and now I'll have two when I get the one I want, sweet)
EV800D Goggles - For $100, these are useable to start out
BetaFPV BT2.0 Pigtails - get that juice
Soldering Iron (I got a 60w all in one kit and I wish I got the TS100
8x Tattu 1s BT2.0 450mah HV batteries - charge to 4.35v
ViFly Whoopstor 3 - highly recommend, charges 6 batteries quickly
64gb SD card for goggles
Skyzone USB OTA Receiver - does every new fpv pilot buy one of these so other people can watch?
2x Meteor75 Pro Frames (everyone and their dog recommends the M75P frame as the most durable, I got extra to build a slightly "larger" build for outdoor - You can use 45mm props with the Meteor75 Pro
Gemfan blades - mine have chipped already, but these don't really break
**After flying for 2 days, I'm ordering 100 M1.4x3 screws ($7) because the motor screws break off from the frame when flying/crashing. They give you extra but I've used them up and I'm on the last ones. I'm also ordering these 75mm u.fl antennas because I've broken the ceramic tip off of the antenna and if I go behind a wall I lose signal. No big deal, a few bucks. UPDATE - after flying about 20 packs, the antenna is better than nothing but not as good as the flimsy original one, but i did bend it a lot. I have a truerc singularity in the mail.
Lets start with the radio:
Radiomaster Pocket - (I'm sure this same thing works with Radiomaster brand radios, I followed along with people on the boxer and zorro - also if you don't have a radio I have to vote against the zorro for the small batteries)
Follow Captain Drone explain and setup switches (STOP at 8:30, where he starts binding. Betaflight update lets you bind from your computer. Start watching again when your drone is connected and the firmware is updated. Later he will walk you through setting up the "arm" switch and flight modes.
Download the ExpressLRS Configurator from Github
**I struggled to bind my Mobula for a long time until I realized that the video and the walkthrough on Github both failed to mention the "packet rate" setting in the radio menu when you press the ELRS lua script. The default is D500, and MOBULA WILL ONLY BIND on the 500hz setting. Anything with a letter in front and you will wonder what is wrong.
Update your Radiomaster internal ELRS lua script to have your binding phrase. Follow these exact instructions, but set the correct packet rate!
Plug in your quad and connect to betaflight (explained in Mobula section)
Go to the Receivers tab, set SPI reciever mode, with CRSF, and the binding phrase you put in the lua script. Save and reboot
Either press "bind" or go to the CLI and type "bind_rx"
Run ELRS lua script and press Bind. There should be a C in the top right corner. Your radio is bound.
Mobula7 1s - Setup and bind to Betaflight
Soldering BT2.0 connector - (gives you more power and more amps, highly recommend) This was my first attempt with a soldering iron. I watched Bardwells 30 minute tutorial and it helped tremendously. I started at 300C and it was too cold, I got the positive off but not the negative. The thru holes are difficult and so small. You have to hold the ground for quite a while for it to come out. I was holding the board and it got very hot, to the point I thought I messed it up. I tried again later with a hotter iron and doing quick 1-2 second bursts and it went much smoother. Take your time, line everything up. I successfully did it, but I should have practiced first.
Download Betaflight configurator (the web version didn't work for me on my Windows machine)
Plug in your quad and let Betaflight (BF) find it.
**SAVE YOUR CONFIG - go to the "presets" tab and Save Backup to someplace you will remember. After you flash the firmware, you have to reload the backup
Go to firmware flasher - Auto detect or the Mobula7 is CRAZYBEEF4SX1280. It should match the target in the top left.
Load Firmware (Online) and then Flash Firmware. You might have to save and reboot or unplug and plug back in.
**This is a huge part where I got stuck (I don't remember if it was before or after firmware). The radio and quad weren't binding. Finally, on the BF Welcome tab there are links to drivers. Download the ImpulseRC Driver Fixer. It is a tool which automatically fixes the incorrectly assigned driver for STM32 BOOTLOADER (FC in firmware update mode)
Move your quad around and make sure the model on the screen matches with what you're doing, and that the arrow points to the front of the quad.
Go to the Receiver tab and make sure your radio is bound with your quad. Move the sticks and make sure they correlate with throttle, yaw etc.
Betaflight Setup - go back to the Radiomaster section to the Captain Drone video. Start after he binds at 8:30. (You will use "bind_rx" in cli tab) It walks you through setting up arm switch and flight modes, etc.
Presets - this is especially useful because you can use someone else's information to get you started. I used the UAVTech Whoop preset, I believe it sets the master multiplier at 1.6x, and it works for me.
Bluejay Firmware - Everyone should have this. It enables bidirectional dshot and rpm filtering and makes the quad run way better with longer flight times. It's an online configurator that flashes the flight controller built into the Mobula
This OscarLiang post describes how to flash your Mobula perfectly. The only changes I made were: both common parameter sliders I moved ALL the way up. I saw 2-3 YouTube videos and posts where they upped the startup power min and max to the most allowed and it runs perfectly. (When you are on the "select target" page, the default leaves it at BLHeli_S, you have to choose the drop down of "Bluejay")
I chose the latest version firmware, and 96khz pwm frequency is recommended for tinywhoops and that it what I used. Definitely play with the startup melody, they have super mario and star wars tones that your quad will make every time you power up. Every time I plug in a new battery I get the super mario bros theme song.
Go back to BF, on the Configuration tab, my gyro update was 8khz and pid loop frequency was 8khz. After I setup the OSD, my controller was running at about 75%+ (you can see the cpu load in bf) which is about the cutoff for being too high, according to my research. Setting it at 8khz gyro and 4khz pid loop was the smoothest running for me.
**Please setup your BUZZER - I did, and the captain drone video he walks you through setting it as a switch. This saved my drone countless times already. Once you crash into a bush and take your goggles off, you completely forget where you were flying. The buzzer helps track it down more than you would expect. Flip over turtle mode is a lifesaver also, that is mandatory.
On the Motors tab, turn on Bidirectional DShot, make sure dshot300 is selected. The mobula7 has 12 motor poles. You can test each motor individually to make sure they are spinning the right direction.
**At this point, I could see the video in my goggles, and I could power up and arm the quad, but it kept jumping, twitching, and cutting power every time I gave it throttle. After lots of things, I checked each motor. Run each one individually and feel if air is blowing above or below, if it's not below, then it's the wrong direction. The solution to this was the checkbox under quad x "motor direction is reversed". I turned that on, and it worked perfectly.
I moved throttle expo to .30 and I like it quite a bit, everything else I left the same.
Closing - I'm sure I forgot/confused a few crucial steps, I'm going to be updating and fact checking these steps to hopefully help someone who was stuck like me. I hope I described each problem I had well enough so that if it happens to someone else, they can figure it out.
Since starting to write this two days ago, I've ordered a couple more things:
TrueRC Singularity 20mm locking u.fl antenna (best antenna, fits under canopy)
Extra set of HM RS0802 20k motors. Mine are champs but if one breaks I want to swap it.
TBS Trimph Antenna RP-SMA male ($20) - Huge upgrade to omni antenna on EV800D, if I find a cheap patch cable that would be cool but I'm saving for digital
Extra Runcam Nano 3 Camera (I want to try the TW Pinch)
2x Mob7 v4 frames - mine has pretty bad road rash (tinywhoop.com has cool colors)
New canopy with camera mount (the first few times you take it apart, the tiny foam piece is a pain to keep under the camera
Have fun flying!!

I've played a ton of final fantasy games, but I've never actually gone through any of FF7. So, with the newest release of Rebirth I've decided to go through and play FF7->CC->the remakes.
Got the OG FF7 on Switch and started playing. My God, almost nothing of this game aged well.
Combat seems okay and Materia seems fun enough - but my bias is definitely towards class systems and more complex combinations.
Story is the only real outstanding point. It's very compelling and the emotional parts definitely hit (for the most part, sometimes the more serious parts come off as really goofy- like when Sephiroth floats like a goon out of the Shinra Mansion). The more campy parts are great and some of the humor hits, but sometimes the dialogue feels off.
Music's pretty good so no complaints there.
Everything else - though, sucks.
The graphics, for one, are really bad. I understand that this was the Franchises jump from 2D to 3D, but my God do the character models look horrible. A lot of the backgrounds are really ugly as well.
The overworld is lame looking and you're constantly fighting with the game on where to go on your screen. Luckily, this is negated by modern ports having a button that shows what you can interact with (sometimes, though, it doesn't work at all).
Now for my least favorite thing: the minigames. I don't think I played a single one that was enjoyable. They were all super janky (such as the initial bike escape, where Cloud swinging barely functions) or they don't even give the correct instructions (the marching one in Junon is the best example of this).
There's also various "platforming-esc" sections, such as in the Temple with the boulders. In this one in particular, there's no great indicator of where you're "safe" and so it's just annoying to sit through messing it up.
I've also had a ton of crashes and freezes, causing me to reset. Luckily, I constantly save but it's still frustrating.
I completely understand why it was considered groundbreaking back then, but, outside of nostalgia, you're probably better off just watching a YouTube summary/walkthrough of the OG game for the story than actually playing it if you want to get a better understanding of the story.
Edit: to make this more clear, this is coming into the game for the first time without ever playing it before. Remove the nostalgia for a second and approach the perspective with that.
Edit 2: I've been downvoted for spitting facts, may Allah praise me for my resilience.

I took the OSCP in late November and passed with a 90/110 in 6 hours. After two hours with no progress, I was sure I was going to fail. I skipped some enumeration and was on a rabbit hole. I took a break and restarted my methodology to get 80+10 in the next 4 hours. Take a ton of breaks and have plenty of snacks/water ready.
I'm sure I could have finished the last two proofs but I valued making sure I had all my pictures and documentation for the report before I would lose access to the machines. I spent the next 7 hours making the report, retaking pictures I was missing, and rerunning through the exploit path to make sure I had everything detailed out.
Before enrolling for the OSCP, I highly recommend the following resources:

• HTB CPTS - Do as much as you can. It is more advanced than OSCP but is a solid source for $8 a month if you have student email.
• TCM - $30 for a month to watch all the videos in `Practical Ethical Hacking` and `Windows/Linux Priv Esc` about 30ish hours of videos that I found help getting started with PEN-200.
• Tiberius course on Udemy for Linux/Windows priv esc. I picked them up for like $10.

I used Obsidian to create my methodology notes. These are the notes that you will use while taking the OSCP. I had the following sections each having a checklist of information or commands to run:

• Enumeration
  • Network Enumeration
    • Port 21 FTP
    • Port 22 SSH
    • Port 25 SMTP
    • and so forth including most common TCP/UDP ports
  • Web Enumeration
• Priv Esc
  • Windows
  • Linux
• Helpful commands (Windows/Linux file upload and download, Python http server, and more)
• Tools/scripts after fresh install

For network enumeration I had a list of port numbers and the protocols. Each port has it's own page where I put enumeration steps such as checking for anonymous access on FTP and checking for ability to upload files to FTP. HackTricks is where I got 90% of this information. This site is amazing for the exam.
For Priv Esc, it mostly referenced `PayloadsAllTheThings` found on GitHub. I also had a section for Helpful Commands. Commands for download/uploading files for Windows/Linux or setting up a python http server and more.

Challenge Labs and PG Practice
Medtech and Relia teach you the basics of initial access, maneuvering Active Directory, privilege escalation, and a few other key learning points. I personally had to use a ton of hints to get through them and I recommend the same after giving a solid 15-30 minutes when hitting each road block. If you don’t know by that point, then I say look it up because you obviously don’t know how to do it. The important thing is to start writing and updating your methodology asap while working through them.
Treat Labs A, B, and C as mock exams. Go into them without using any hints if possible. If you are struggling to complete these without hints, then you need to improve your methodology. I would recommend PG Practice and follow the TJNull list. IPPSEC also has some really good walkthrough videos on YouTube for the TJNull list.
I did about 5 HTB machines but they are more like a CTF. They had value for learning but I would strongly recommend PG Practice over HTB.

So recently I had issues with my brand new FPV drone. It’s a CL2 6s drone with dominator hd goggles from fatshark. Tx12 remote controller from radiomaster. Receiver is an rp1 2.4ghz from radiomaster. Idk what vtx this has. The fc and esc is t-motorF7. All parts came stock from rotor riot.
Well anyways I had 3 issues and many many questions.
First issue was dshot stopped working. My response? Bought another esc board. Same brand same everything… still doesn’t work
Second issue. Fc settings were fucked cause I don’t know what I’m doing. Flashing and erasing everything was my response. It’s updated to latest version(I think). Set everything up and motors won’t spin when I go to the motors tab in betaflight. And yes the “risk slider thingy” is on and they should spin but they don’t. I also have a new fc if I need to replace it.(same version)
Third issue is the most aggravating. My receiver and transmitter….. they don’t connect. I bought a new receiver(same type as before) and I have no clue how to set it up(I need a walkthrough for setting up and updating to latest firmware and pretty much everything). They also didn’t connect after the first 2 flights. And I didn’t even crash.
And everything is soldered correctly and all connected are good(tested with voltage meter thingy) and I tugged softly on the wires and nothing came loose.
But now I’m sitting here with a paperweight and idk what to do about it.

I’ve exited out and back in, and taken out my mods and put them back in but nothing is fixing it.

This is in the walkthrough with Geordie. "Locate the disturbance" When you press GO it beeps but nothing happens. The screen is grayed out and you can't do anything bur esc out. Any ideas? I have a support ticket in but could be 24-72 hrs. Running Windows 10. Video drivers up to date. Tried to re-install the game, no help. Thx

5 step walkthrough using free software for converting a Chromebook into a functional and usable Windows 10/11 PC with a $12 UEFI bootable U3 sdcard as the Windows C Drive. Kind of along the same lines of how Ubuntu Live works on a USB device, but with persistent changes.
Note- This can be done with whatever OS you want, but for me, I used a lite older build of Win10 customized for low spec Chromebooks. While you can do this will full Windows versions, it may be too much for a low spec Chromebook to handle. Anything under 4GB memory (like the CB3-131), I'd go with a lite OS.
Two things I'd do first:

• 1. See what is required to disable write protect on your Chromebook ​ ​
• 1. See if x64 Windows drivers are available for your Chromebook. You can see if they have them here, or Google your model ​
  $12 U3 (V30) sdcard (Write speeds around 90 MB/s and read speeds around 200 MB/s), and the free Macrium clone/imaging software made it doable.
  

Another idea is an external SSD drive. Or even a U3 V90 sdcard (a 64GB one runs around $38, and will give the same read/write speeds as a eMMC with around 250/300 MB/s write and 280/300 MB/s read).
I briefly considering using an old USB 250GB WD Passport HDD that I just use for backups, but it just seemed like it would be a PITA to carry around.
U3 V30 speed. It's not quite as fast as the eMMC (around 330 and 200 MB/s read /write), but it still seems snappy enough for normal use.
For comparison, a typical 7200 RPM HDD will deliver a read/write speed of around 80-160MB/s.
The highest disk speeds I have seen on this CB3 were around 170MB/s or so, and that is when it was installing Galactic Civ. 2GB Memory is the bottleneck.
​
Step 1: Enable Developer Mode
esc key + refresh key + power key, then ctrl + d key then Enter to turn off OS verification. Chromebook will reboot and require setup.
​
Step 2: Remove write protect screw
https://youtu.be/R0KQwr6WQHc?si=9BtTrV92rsyDzZRv
(note- If you have a device other than the CB3, your method may be different to disable write protect. Google it)
​
Step 3: Flash UEFI Firmware
Firmware: https://mrchromebox.tech/
open a shell command ctrl + alt + t key , enter (copy/paste command, then push enter key):

Shell 

Then

cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh 

If you get something about curl not being installed, then install curl, and the do the above command again.

sudo apt install curl 

​
Step 4: Install OS and Install Drivers (you basically want the x64 version of everything)
x64 Win10 Pro 1703 Potato OS
x64 Windows 11 21H2 Superlite OS
Official full Win10 OS
Official full Win11 OS
Windows 10 S Windows 10 S comes as a direct alternative to Google’s ChromeOS, and from what I understand, is a free license product. It is a lite version of Windows which will likely run better on a Chromebook (this is the upgrade installer, so install Win10, and then run this) Source
/////////
x64 Win10 and Win11 drivers: https://coolstar.org/chromebook/windows-install.html
I made the iso bootable on a USB thumb drive with https://unetbootin.github.io/
​
Step 5: Install Macrium, and follow prompts to clone drive Macrium Reflect Free Edition
First thing I would do is create the bootable USB recovery drive using a 2GB thumb drive.
Clone the 16GB drive containing your installed OS, boot EFI, the unformatted partition between the two, (and recovery partition if you want, the Potato edition OS recovery has nothing in it though) to your external media.
One thing I like about Macrium is you can drag and drop and reorder partitions. It'll also resize to fit space.
(after you reboot, access your boot menu usually 'esc' after restart, just keep tapping it, and boot off sd (if that is your cloned card/device). I'd change the boot order, and save it so sd (or whatever you used) is first boot device)
If for some reason it won't boot off the external drive after clone, then reboot from the Macruim recovery USB that you created, and select 'repair boot' option (you can also use this recovery USB to create and restore backup images).
You can also wipe the old OS on the internal drive. After successful boot off removable drive, open up the diskpart in cmd, and enter 'list disk', and then select the 14GB disk (e.g., 'select disk 0' if disk 0 is the 14GB one), then enter 'clean'.
I set the SDcard as gpt in diskpart prior to cloning.
Once the volume is selected
Enter:

clean 

Then enter:

convert gpt 

Then format it as 'ntfs'.

Now on to my new toy...a class 3 midrange V14 G4 AMN, Ryzen 5 7520U, Radeon 610M, 8GB memory, 250GB SSD, Lenovo Win 11 Pro laptop for $299 new. Giving away the Acer CB3-131.

My background: I have a BBA in Management Info Systems from back in 2003. I got certified in A+ and Microsoft certified Professional back then. Never worked in IT, I have some experience in web development, mysql, php apache. Worked as a computer programming teacher at the high school for 8 yrs. Left teaching 9 yrs ago went to the restaurant industry, but now I want to get back to the technology field and Cybersecurity interests me. So I am not totally new to this, I will be taking the Security+ soon.
I have done 10 HTB easy with walkthroughs and understood what was happening on those walkthroughs. I have done TCM's PEH course. So, I was thinking of doing their PJPT and then PNPT certifications($600 for both) before attempting OSCP, BUT it is going to take me about 6 months to save for the 1499 for OSCP(I have bills and a family :)
My question is, should I take those TCMs certs before OSCP or should I take their priv esc courses, pivoting courser, learn tools etc. do more boxes and save that cash to fund the OSCP cert and do some more prepping for the next 6 months? Will the PNPT help me advance my skills to attempt the OSCP? I was thinking that maybe a year to learn a good methodology so I can absorb it all.

Unsure if anyone has had this but interestingly after checking walkthroughs, I haven't noticed anyone have this...
The machine I was doing had a priv esc which meant I needed to use nano in order to execute a root shell...
When i load nano and press CTRL+R, I get ^R appear and the command isn't used. I hit enter and end up with text over lapping and all sorts of random mess. I've tried on different VMs and get the same issue. I have also even tried on a VM on a different computer. Does anyone know what causes this? In all the walkthroughs I've watched these commands work and there is no dfifference to the route taken to get here.

Platform(s): dont know seems like a gamecube ps2 early ps3 game
Genre: somewhat fixated camera somewhat free camera action game if i remember
Estimated year of release: early 2000's
Graphics/art style: similar to re4 is how I describe it
Notable characters: white haired lady badass main character type
Notable gameplay mechanics: there's a clock ticking in the top left going down and down you can add time to it but the main purpose is to find out what's causing the end of the world (I think)
Other details: I'm pretty sure there was a street level and a place mostly white where you could add time and a mgs3 esc menu where I think you could add time I remember watching vids of this game on YouTube a while ago and I thought it was really cool (at the time I was watching a lot of walkthroughs from early 2000's games)

I've completed most of the module but been stuck on the last part of the section. I understand the module and what its trying to teach but I keep running into typos. I've gotten help on the section and worked on it for several weeks. I keep on having typos with the PrivEsc walkthrough of Nibbles HTB Box on HTB Academy.
I looked for a good walkthrough on YouTube of Getting Started Module and I couldn't find an up to date official IppSec video of it so I'm looking for a high quality YouTube walkthrough of Getting Started Module to take notes on.
The section I'm stuck on is Nibbles - Privilege Escalation section.
Please advise.
