@DillonB072Attempting to make a logo for my Hack Club - so far I’ve just ruined the official one :face_with_peeking_eye:
@awdev7+Got the buck converters working and powering the H bridge and microcontroller. Beeg battery with insanely high discharge rate. I've got some firmware on the microcontroller working with the H bridge, so it's almost time for some self-driving shenanigans. Just need to finish mounting my sensors. And I also burned like 5 of those stupid LEDs out yesterday. BRO THEY CAN'T EVEN RUN NICELY ON A DEAD 1S LIPO UGHHHHHHHHHHH
@ShauryaGupta1It is really amazing to work again with the basics…
@DillonB072Using Flasgger, and a lot of yaml docstrings 😭, I've written some docs for the Subsonic section of Rhea's API
@EvanGan7+Day 70 of #100-days-in-public.
New day, new video!
@KarthickArun1Wow , didn'y know scrapbooks storage for photos & videos was AWS S3 I use it for hosting images on html sites all the time been using it for a while and this was nice to see!
@cupcakes7+Trying to find an electret microphone for my project! 🎤
@Element-XP1I made my first electronic without a tutorial!
@awdev7+Custom 3D printed mount for my ultrasonic distance sensors. Brass inserts to bolt into the chassis.
@LuceHeinrich1Early development version of a dungeon crawler I’m making with some friends, all running in p5.js via electron@awdev7+Got my buck converters working! Voltage adjustments are in place. This is a 4S 3Ah LiPo with an XT60 connector. It connects the buck converters in parallel, meaning they don't have any voltage diminishment and extra current draw on one bus doesn't affect the other device. 12 volts from the buck converters is going to the H-bridge motor driver and 5 volts is going to the Arduino Mega (not pictured). Hope you guys like it!
@KarthickArun1Saw this license plate that was “CAMERAS” omw to school
@EvanGan7+Day 69 of #100-days-in-public.
Still in video!@pragyarajfb130Went to the lake nearby!! Back to hackclub after a long gap
@awdev7+Got some boards for a project. We have 5 ultrasonic distance sensors and 2 adjustable buck converters with voltage displays. Stay tuned for more developments soon 👀
@karmanyaahm0Chessbot can now follow a lichess game!@adammakesthings0Design day 1 went well! Next up is finishing Z- and "X"- axis belt coupler/tensioner systems
@awdev7+I finally made physics go brrrrrr woot woot
@awdev7+Got some basic collision working finally. If you look closely, the bounces downhill go further than the bounces uphill. The little red sticks coming off each face are the normal vectors.

Today is my last day in Houston. Today my robotics team (and many others) visited the Johnson space center. We got to see a space shuttle mock up and also the old mission control center which is over the new one. Overall, I had quite the time in Houston and look forwards to returning some day for robotics or rockets. Tomorrow should be back to normal updates, where I hope to improve my blot pathing planner.
@cupcakes7+Made idli(rice cakes) and rediscovered kitty cookie cutters, so here we are :kitty-awe:
@AriMastor05 months into this project and it's finally finished! This is a gadget geocache for my local maker space. Custom PCB (funded by Onboard) interfaced with an Arduino for controlling LEDs in the eyes, giving instructions on how to solve the puzzle through the speaker, checking the password entered, and controlling a solenoid to open the hatch on the bottom when the puzzle is solved. Hand crank on the side turns a geared stepper motor to charge supercapacitors that provide enough power to last a few minutes so nobody has to worry about charging or replacing batteries. The whole thing is covered in epoxy for weatherproofing. Hopefully, it will be up and running in a week or so!
@awdev7+I found out how to calculate the normal vector of a line and wrote my own algorithm to normalize it within (-1, 1). It may not be amazing or look great, but it's the small victories that count. Next step: getting this to work with a physics system.
@ArnnavKudale0working on some landing feet things for my 1kg tricopter, tpu clearly takes the win here after some quite hard landings on asphalt
@Tom0I don't think that line was meant to go into code
@RyanDiLorenzo-U04JGJN2B400I got the CH32V003F4U6 RISC-V microcontroller today and I wanted to program it with the USB protocol to make flashing a whole lot easier. To flash this microcontroller you need another microcontroller called the WCH-LinkE Mini. I plugged the WCH-LinkE flasher into my computer before installing custom drivers for it and got some cables to connect the flasher to the actual microcontroller. After this I tried to get the compiled binary file to flash after seeing they only have the C code, the instructions looked simple enough, just a simple "make build" command in the directory? I must have spent an hour and a half troubleshooting on why I was getting strange compilation errors and "SYNTAX ERROR IN LINE 502 OF FILE", it turns out that you have to copy another Github Repo's source code into a folder on the USB repo which contacts the C protocol file. Finally it compiled into a binary then I saw it wanted me to use the offical Wch-Link Programmer tool which I couldn't find a working website anywhere - the official website was down and there were no copies. I finally found and decided on using one built in Rust and after learning how to use the flash command, I kept getting the same generic "No microcontroller found". Another one and a half hours pass and on the readme file on the main repo, in small words it says to use the PD1 pin. Everywhere else I'd looked they said to connect to the SWIO pins or the UART pins and nowhere else said to use this specific PD1 pin only. At last, I finally got it to flash successfully, but upon connecting the USB-C cable right to the microcontroller, it wasn't showing up on Windows with the default pinouts. In the instructions though, it said to change the USB-C pin depending on what the microcontroller is connected to, seems simple right? Wrong, I purchased the microcontroller dev board off AliExpress and there was no mention anywhere of the pins or a pinout of where the USB-C data positive and negative lines are connected to. Not even any other github repos or anywhere had something that looked exactly as the PCB dev board I got. My next task is to reverse engineer the traces to figure out what exact GPIO pin the USB-C data lines are connected to, but this will prove to be tricky... Or maybe I can message the AliExpress seller but who knows when they'd reply.
TLDR: It still doesn't work after all the issues I've had, the problem I'm facing now is the proprietary PCB I got from AliExpress which they won't post the schematic to.
@awdev7+I am beginning my improvements on my JS physics engine, first with bounces. Now to implement surfaces with normals and normal reflections. This is quite fun!
@EvanGan7+Day 66 of #100-days-in-public.
Today was EPIC. My FRC team placed 6th in ranking and got to be the 5th alliance captain. We won our first match, but then lost our second and third. We had a really fun time though, and started rooting for a with one of our friends on it. During breaks between matches on the world stage, there were some fun half time like shows, one of my favorites being a game of Simon says, which some of my team members were in.
If you are around Huston next year around First worlds I would 1000% recommend visiting Thursday or Friday and all of Saturday. The event is amazing and has amazing production quality.@Charlie0needed a 32px version of the sprig fella for a thing, so i drew one :-)
