wahoo!! this uses a Go server running on my computer, which interfaces with the arduino to get nunchuck data (pings the arduino, which returns binary data via serial), & as a proof of concept runs an http server which is being called by a lil html/js app to display joystick position

got a wii nunchuck hooked up to an arduino! thinking of using this for FRC control :>

Soldering male connectors to the headers on an Arduino Nano (We have to get Mr. Robot done next week and don't have time to order proper jumpers 🙃)

Now that my #droneproject & #hardware-party:winter-hardware-wonderland: have ended, I was thinking about starting something new!! So here it is! I'm going to develop a game #gamedev :tw_video_game:, But before that, can yoh all please tell me what this is? It looks like a sprig:sprig-party: ? And i got it as a Hackathon prize! Please tell me what it is? Thanks!

Greetings,:beatsaber: fellow Hackers, Hack Clubbers & hardware wizards! It's Day 12 of WHW #hardware-party, and I come bearing exciting news from our winter wonderland drone project. After weeks of hard work, late nights, and endless cups of hot water (Did not have cocoa:sadge:), we've finally done it! Our drone is complete!!!:aussieparrot: The drone has very cool attachments & features like a high-resolution camera and advanced sensors that can detect changes in temperature, humidity, and air pressure. It's highly adaptable and can fly in humid, fog, and terrain which is difficult to traverse! Along the road, we faced our fair share of difficulties, from debugging code to testing flight stability while being ill, but I overcame them all with the help of my trusty hot water and team spirit. It was all worthwhile in the end. We have developed a drone that is not only useful but also a tonne of fun. In the end, I would like to T:hackclub-slack:ANK @HackClubBank-U04SEGJ8WN5 for funding this project and @MelanieSmith for overseeing it, and @TanishqUpmanu-U04F0RWGARH for helping me so much! Now, let's raise a cup of hot water (cocoa for the rich people☕) to this fantastic journey of building a drone project and celebrating its end. This will be my last WHW post and #drone series. Thank you all for supporting! I'll see you all tomorrow! Bye, Goodnight! PS : Gonna get into all the #44-74 stuff going around! Gotta solve those mysteries YK!

Day 10 of WHW #hardware-party, Today I calibrate my fsi6s transmitter; binding it with the receiver, I was so sleepy that i also messed up the expo settings, but later got it right! I'm so tired rn that the only thing i can think about is sleep! And because of that I'll see you all tomorrow! Bye, Goodnight!

Day 9 of WHW #hardware-party, Ahh! Such a tiresome day! Had a lot of guests come over and the fact that I'm in my village makes posting even harder! Today I had a meet with my partner and we setup a local network to upload sensors output to local server and examine it through esp8266 WiFi module. Well, that was it for today! I'll see you all tomorrow! Bye, Goodnight!

Day 8 of WHW #hardware-party, I had to head out early because we had to go to our village :villager: for EID💫 . So, I woke up really early and did some wiring and assembled the bldc motor & tested the net thrust component, I got some reading around 1.1kg in net force, and then headed out. Rest of day was packed with EID preparation and i am awaiting tomorrow :akkoshrug: eagerly. Well, that was it for today! I'll see you all tomorrow! Bye, Goodnight! PS: After being yelled at by my father for driving:driftt: , (In his own words) "weirdly" :weirddude: i tried some cool art filters and edited some pictures.

I KNOW I AM LATE! But hear me out! Finally, the doctors let me go! After severe fever and dehydration, I finally present: Day 6 of WHW #hardware-party, I know I am late but my mum taught me not to leave things unfinished. So, today I looked up the satellite view of my location and marked up the mission point in mission planner! Well, that was it for today! I'll see you all tomorrow! Bye, Goodnight.

Ok guys, I used an Arduino and some jumpers from :winter-hardware-wonderland:, bought some parts and finally managed to finish a complete a hardware project without exploding anything:)

Restoring Mr Robot with Vex Cortex and ROBOTC milestone (with @Jaxzog)! The master brain is now talking to the follower and successfully sending values over UART!

Just got the plaque and stickers in my mail! :yay: (My sticker collection continues to grow) It looks (and smells) AMAZING! It's customized as well :O P.S. I think the short and lang bars next to the "Winter Hardware Wonderland" text is binary. It seems to be the first letter of my name :tw_thinking_face:

Ampli-Tie final day 5, March 25th - the day has arrived! - Solder the microcontroller (I'm just powering it off the mCu USB port, past me calculated a peak of 100mA would be reasonable, future me found out the whole thing only consumes 26mA). - Copy a whole bunch of code off Adafruit, but the mic doesn't work, turns out, for some reason, my painted mic is broken and always outputs 3.6v. Hurriedly swapped to another mic, unpainted, so it would have to hide under the collar (T-2hrs). - Still cannot get the mic to work (T-90m). Might as well get static effects working. Got timing on rainbow cycling adjustable from the app, and made sure static color worked. - (T-60m) it works! Now I actually gotta tie the tie and dress up.

Ampli-Tie backlog pt 2! Day 4, Friday, March 24th. Skipped school and the pressure was on, I have to get something working before tomorrow. I also have UIL this evening and tomorrow morning so just have ~9 to 4. - painted microphone - sewing, sewing, and sewing - I made the hard decision of splitting it into two halves, one above the name tag, and one below because connecting them was a nightmare. So, I used a wire to connect them (I got this really nice stranded 24AWG silicone wire that is extremely flexible and blends in perfectly). OTOH, connecting the two halves using an actual wire created a "highway" that reduced the resistance (conductive thread) from the microcontroller to any individual LED).

Ampli-Tie backlog! Day 3 (March 22) - sewing + acquired fray check to tie up loose ends Day 4 (March 23) - Hours and hours of sewing - After having to hold open these tight spaces gimme my surgery license already - first test, using alligator clips to connect the microcontroller and power 🎉

Small ship (bigger one coming soon hehe)! At #horizon I built an unnecessarily ~complicated~ hacky project involving Spotify + Neopixels. Basically, the web interface at horizonmusic.vercel.app allows everyone to add music to a Spotify playlist that I play (which means I have ultimate control I guess + yes you can technically still add music) without having to log in (especially if they don't have an account) + automatically filters out explicit songs in the search so nobody adds explicit songs. Waveform with p5.js and Tone.js record surround sound (coming from speakers and other close noise) and transform it into a cool waveform, while a set of LED lights (Neopixels) flash along to the music, utilizing an Adafruit Feather Huzzah to wirelessly communicate with a computer (computer mic -> computer -> computer processing -> send FPS to Adafruit -> flash Neopixels!) through the amazing audio-reactive-led-strip library. The Neopixels we got didn't work fully, but the result was still cool! github.com/jianmin-chen/spotify-collab (and I might be getting working Neopixels for another project!)

update on :winter-hardware-wonderland: macropads! almost fully assembled one — just need to buy screws and standoffs to attach the bottom — and they work!! the 3 rgb leds are individually addressable, and since it’s powered by a pico, the keys and leds are all customizable (here I have circuitpython loaded on the pico, running a rainbow animation) i think these would be fun hackathon prizes so if you want some for your hackathon reply/dm me ig?

Custom Ampli-Tie Day 2 - Step 2,3 1. Sizing and learning how to tie a tie 2. Placement tests (fewest lights that'll look decent) - 13 LEDs every 3 cm apart was optimal 3. Harvest Flora NeoPixels from an old non-functional project and then spend foreverrrrrr cleaning them (removing the superglued thread) 4. Ordered microphone and ribbon cable

Winter Hardware Wonderland #hardware-party There were complications in getting the Hack Club Bank to work and parts were slow to ship from overseas - but finally I got all the parts to work and here is the first prototype of the Triton Amphibious Rover! github.com/hackclub/winter/blob/main/thelouisgan.md The RC controlled rover features a LEGO Technic vehicle that I coupled with a motor, and for the water side of things I rigged an underwater motor and 3D printed rudder to a 25KG servo motor. All this is remotely controlled with an RC so that you can take it to explore different terrain and locations! It is also powered by a rechargeable LiPo battery and will be able to operate up to 15 minutes on a full charge in optimal conditions. Will update more photos and videos of it in action soon! Please do give feedback/suggestions as this is my first big scale project and thanks to @MelanieSmith and @belle for the support.

I forgot to show the #hardware-party people, but here’s my electronics cupboard The first circuit is a 16 bit flash ADC (the ICs are 741 operational amplifiers being used as comparators); it’s part of my bigger project The second circuit is my friend’s pulse oximeter (I’m wheezing because the CO2 levels were ridiculous (we had been in there with the door closed all day)

Day 2 of WHW #hardware-party So, today I am coding the GPS Module System, I added and altered the code to enable more precise locations for better navigation while flying the drone. Tomorrow I will start working on the hardware! Thanks.

Day 1 of WHW #hardware-party I was so busy with exams that I forgot to post! Sorry guys. So, Here I am Coding the altitude calculation system for my team's drone, A tip for others who are facing problems with APM, for example: so I was not getting the correct reading of altitude in APM so I used (True Altitude = Indicated Altitude + (ISA Deviation × 4/1000 × Indicated Altitude) to get the correct reading.

WHW day +6: after hours struggling with wifi connection, I have succeeded to get on hack club slack and make a post on the scrapbook. Here is what I did during my week without internet: • print time on serial monitor thanks to the RTC library that I've already install (i have also displayed them on my lcd screen but i forgot to take pictures) • read some books about C programming language to code my arduino better (don't have C++ books but it was the best I got without internet 🥲) this week I went finish my holidays to the mountains ... but I forgot to take my arduino 😭 no progress this week sorry if my project take a long time to get finished (I think i'll not be able to continue during school)
