@EvanGan7+Day 69 of #100-days-in-public.
Still in video!@pragyarajfb131Went to the lake nearby!! Back to hackclub after a long gap
@awdev6Got 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 👀
@karmanyaahm1Chessbot can now follow a lichess game!@adammakesthings0Design day 1 went well! Next up is finishing Z- and "X"- axis belt coupler/tensioner systems
@awdev6I finally made physics go brrrrrr woot woot
@awdev6Got 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.
@EvanGan7+Day 67 of #100-days-in-public.
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!
@awdev6I 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.
@awdev6I 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 :-)
@HenHen0It was hard for sure, but at the end of the day, we made a really fun project!
@KarthickArun0Got the #the-trail postcard , though it’s to bad that that I will be busy during that time but sounds like it’s going to be fun hopefully a hack club from Arizona is able to go, also I wonder how Thomas got these printed , for context asking for #grandcanyonhacks
@AlwaysBusy0Just arrived and came out so gooooooddd!!!
@rivques0more proof of concept testing for #the-traildev-computer: seeing how a 320x240 screen feels in the console
@cupcakes7+Did some more soldering today! (also found out it's supposed to be ventilated because fumes, explains my allergies :oops-text:) Probably shoulda watched a tutorial the first time around :sungals:
@EvanGan7+Day 65 of #100-days-in-public.
Today apparently Mark Rober was at the competition, some of my fellow team mates saw him. I played a game for a free box of their new line of build boxes & won one for free. As I was walking around the venue got to see their life size version. I found this one a bit odd, but the CIA was there recruiting. Also, I got loads of ribbons for my name tag, unfortunately I only started today and if I had started yesterday I probably would have gotten a lot more.
@Tom0I started using graphics mode in my OS, so i have to render fonts now
@arav0working on a new waitlist endpoint for toriel and the slack
@awdev6I did a basic implementation of gravitational physics in one HTML file. I made it in 1 hour, and you can try it out here: aaronw-dev.github.io/physics-basics
I will work to improve it, but for the time being, I think it's pretty decent.
@Kokonico0working on shenanigans@EvanGan7+Day 64 of #100-days-in-public.
Today at FRC worlds I stopped by the hack club table, where I setup the demo blot and then ran off to scout matches for my team. I also saw a small HAAS 3 axis CNC, and some Disney imagineering stuff.
@awdev6Soldered two of my motors to the ESC. Did a test with battery, and it works amazingly! I got the du-du-du sound! Now to wait for the ESP32 (yes that's my FCU) and props to arrive.
@cupcakes7+Soldering stuff!! it’s so much funnn :roo-yay:
@DillonB070made a super simple website for the beta boba drops fund
very different style to what i normally do, but i’m pretty happy with it. it’s simple but it works well i think
@awdev6A major step towards the first test flight of automated bomb water bottle dropping bomb!
@AaravYadav0#100-days-in-public day16
i really want to make a chess ai, it seems like a fun idea and i want to make one that can beat me so something thats actually alright at the game. I think am sort of inspired by this youtube vid at 36 min in

@EvanGan7+Day 63 of #100-days-in-public.
Got up super early to fly to Houston for the first robotics world championship. Really incredible event, the venue is gigantic & there is also a First lego league and first tech challenge event going on there. Got to see some cool stuff, like a Haas F1 car among other things.
@rivques0Tested a driver for the raspberry pi that lets you put a matrix keyboard on the gpio pins as preliminary testing for #the-traildev-computer
