This is an IRL Minecraft jukebox that plays 3D printed discs, powered by a Raspberry Pi Zero 2, an RC522 RFID board, and some really crappy Python code. This project is being made for and funded by Hack Club's Highway program.

A battle bot that uses plasma arcs to defeat its foes! It also has a easily replaceable/swappable horizontal spinner weapon and powerful motors all around. The plasma arcs won't do much to the opposing battlebot's electronics, but their main feature is melting and softening the outer shell. It has an adjustable length as well. I made this because I thought it was a really cool idea to see a plasma fire battle bot in action! I also wanted to get into RC more and battlebots overall are really cool and fun.

My personal macro pad for productivity, with 6 keys and a rotary encoder, as well as a MiniLED. As mentioned in the Repo, this was my first serious project on KiCad! Quite a jump from beginner to expert - I think it turned quite well; hopefully it works! This project took around ~8 hours of work, a day well spent!

4 way USB Hub this board is a usb hub that will extend the amount of usb-A ports I have on my computer so I can connect more things to it at the same time. I need this because my computer only has 2 usb ports be default and hubs are kinda expensive so I thought it would be cool to make one myself. $33.76 AUD One challenge was trying to find through hole versions of all the parts in the tutorial. I looked for about an hour before finding out that JLCPCB does an assembly service.

ESP32-powered smart doorbell with smart AI-powered detection, that automatically captures a picture that is sent to a Discord webhook via WiFi when the doorbell is rung, which triggers an integration that can set off a custom ringtone on a mobile app. Utilizes a pushbutton to actuate a buzzer and LEDs. Powered by a LiPo battery and enclosed in a PETG near waterproof case with TPU seals. Additionally, this module contains a temperature and humidity sensor that can be called through a Discord bot from anywhere in the world at any time to get precise temperature and humidity readings. Additionally, an ultrasonic sensor detects movement and wakes up the camera to take a picture and identify it through a simple ML algorithm. NOTE: This is a software-heavy project, I am aiming for this to be a Tier 4 project, but if it only makes Tier 5, I understand. I will try to supply as many of my own parts as possible to keep expenditures to a minimum.

This Weather station shows you the weather based on where the slider is. But the places to get the weather are all over the place! It could drive someone insane while trying to understand how it works.

PCB LAYOUT

This is a project made by me with the help of Hack Club - Blueprint Workshop

NOTE: This was once a tickets-only project, but due to a recent rule change I was unaware of, it has been updated to a grant project. NOTE 2: THIS SHOULD BE A DESIGN REVIEW, ALEX PLEASE CHANGE THIS TO DESIGN REVIEW I THINK IT MESSED IT UP WHEN I RETURNED IT!!! It's come time for me to make my first rp2040 devboard. Let's see how this goes! I'm so excited! To differentiate my project from other similar projects, I'll be adding an addressable LED and a simple temperature sensor. Later, if I have more time, I'll integrate a JST battery connector and charging system and then have this built with my own money.

This is my macropad. I spent a lot of time on it and i hope you accept it. the things I need: - 11 MX cherry red switches(or anything linear you have) - 12 1n4148 diodes - 1 ec11 rotary encoder with switch - 1 xiao rp2040 - 1 128x32 i2c oled 0.91 inch (pls dont solder this) - 1 pcb - 2 4.7k resistors - 1 usbA to usbC cable (pretty pls🥺) - cool stickers(im in #alex-containment-chamber) - can You print the case in Carmine red with black keycaps? - 1 encoder knob, same colour as keycaps - 4 of the insets you said to use on the hackpad website - 4 14 mm long m3 screws - any PCB colour all parts are through hole thank you.

The Goal of this project was to build a simpler datalogger for model rockets to collect the info needed for most rocketiers from multiple sensors including an IMU and Baro. We built this as a dev board so when we eventually finish designing the larger V1 board, we can weed out issues before spending $400.

This project is a pager powered by an Adafruit Feather HUZZAH ESP8266. It interfaces with Slack so that when you send a message in #pager in the Hack Club Slack, it notifies you by playing a little ringtone and then displaying the message and sender. It also has a quick response menu to send a few prewritten responses to messages you receive. I got the idea because Slack had been really glitchy on my phone recently, and it wasn't always sending me notifications, so I thought "What if I made a device that was just for Slack notifications?" My hope in the future is to expand it to not just #pager, but everywhere I'd typically receive a notification as well.

A cyberpunk-themed STM32 development board featuring Bluetooth 5.1 connectivity and integrated Li-ion/LiPo battery charging support.

This is a 75% keyboard fully designed by me, including the PCB, case, and firmware. It is designed to use KMK, a circuitpython-based firmware for keyboards! I included a rotary encoder, as well as a few "action" keys on the side of the keyboard which can be reprogrammed to anything you want, such as media controls, text controls, or any kind of shortcut you can think of!

I was inspired to make my printer based off the current problems I have with my A1 Mini. While the A1 Mini is a really fast printer and does its job, its still *mini*, so for my custom printer my number one goal was to have a large build volume and then add custom features like AMS system and build failure detection.

This is a custom, 4 key hackpad, with 2 LED's and a EC11 rotary encoder on it that can be set to do different actions like volume control which is written in KMK.

I made a tiny (33x18mm) development board that uses the ICE40UP5K FPGA paired with a CH552 MCU on board for programming the flash.

This project checks your acceleration and give a different colour output based on it. if you accelerate too fast then It starts beeping telling you to slow down

- name: "Kai Pereira" slack_handle: "@Kai Pereira" github_handle: "@KaiPereira" tutorial: https://jams.hackclub.com/jam/hacker-card --- # Hacker Card <!-- Describe your board in 2-3 sentences. What are you making? What will it do? --> I built my first PCB with the help of the hacker club tutorial. I added a qr code, urls and some designs. It transfers a url wirelessly on tap. <!-- How much is it going to cost? --> It costs $2 - $4 ($2 for me because I got the coupon code). <!-- Tell us a little bit about your design process. What were some challenges? What helped? ***Totally optional*** --> A little bit challenging to get started because there's so much going on. Sometimes only a few layers would be on and I'd be really confused. It was fun to make though!--

I didn't realize that you don't have to build EVERY project before the due date, so I decided to make a printer. This is a printer idea I've had since Undercity and have been wanting to execute on. It was made in 24 hours!

Powdy is an all-in-one power reader via USB-C! Just plug it in to your device, and watch as the power draw reading come onto the OLED screen. This device mostly uses one main component to read the power- The INA226, along with the MCU- the ATmega328P-A.

This is my first-ever hardware project. It is a nine-key macropad with an OLED and two LEDs.

A development board based around the VS1053B Audio Codec!

A controllable neopixel matrix with a rotary encoder! The controller can change the brightness. There is a buzzer that also buzzes Twinkle Twinkle if pressed twice :) A mini 0.91" oled for monitoring is also present and I hope that I can play cool animations with this display!

A tiny yet mighty, sturdy and swift 3D printer, designed and optimized to run at tremendous speeds.

--- name: "Max Kendall" slack_handle: "@Max Robotics" github_handle: "@maxsrobotics" --- Tiny4FSK Tiny4FSK aims to run on 1x AAA battery to transmit 4FSK signals on the amateur radio band, allowing for high-altitiude tracking systems for high-altitude systems. The board itself costs $7, with $17.80 shipping. In total, the board costs $26.35 with tax and shipping included. Ahh, I've been working on this since August, trying to use the SI4063 in code to get the drivers right.

This integration connects Lapse with Hack Club to create timelapses of your projects using programs within the Hack Club ecosystem. The primary purpose of this is to serve as a companion to the Lapse project, making it easy to create timelapses of your projects. Not just coding, but anything you build, design, craft, or create.

name: "Taran Mittal" slack_handle: "@Taran Mittal" github_handle: "@Overlord-Runt" tutorial: all original --- Ghost keycahin This is a project I made for trick or trace and is a ghost that you can use as a keychain. It has a bettery connector and green lightup led eyes. If you press the button on its nose it mades a lound noise to scare away your friends. It will cost $4.53 USD I wanted to make something spooky for trick or trace and was just messing around to find something that looks good until I found this. (also I dont really want to spend my funds on this, I just wanted to do trick or trace for the stickers)

Optimized Macropad

An optimized 17 key macropad with RGB

its a led matrix diplay with neopixels order total is 37 $ but will increase when i add the neopixels  as we need to preorder them so i can not get the price with all assembeled As for the challenges, this was my 1st pcb without any help. This one took me a bit of time as I learned about things like neopixels pull ups and pull down. but it was fun overall! also I will design a case for this pcb and will print that

PR1SM - Stacked Acrylic Keyboard

PR1SM is a minimalic, stacked fully backlit acrylic keyboard using a small 2 layer pcb. It's made out of laser cut acrylic, so combined with the neopixels, it'll have a really cool effect.
