Shortly after buying a 3D printer, I was browsing [Thingiverse](https://www.thingiverse.com/) and happened to come across this [Sherbet gaming keypad](https://www.thingiverse.com/thing:3744277). I decided to print and build it as a practice project. # Overview ## Frame I downloaded the STL files from the aforementioned [Sherbet gaming keypad](https://www.thingiverse.com/thing:3744277) and printed them. ## Microcontroller Although the Sherbet gaming keypad is designed to use a ProMicro, I opted to use the [Waveshare RP2040-Pico](https://www.waveshare.com/rp2040-zero.htm). I am very fond of this microcontroller. ## Programming Language [CircuitPython](https://circuitpython.org/) + [Adafruit HID](https://docs.circuitpython.org/projects/hid/en/latest/) ## Required Parts Most of the parts can be found on Amazon. - [Appropriate key switches](https://www.amazon.co.jp/gp/product/B08ZRWVKHS/) - [Appropriate diodes](https://www.amazon.co.jp/gp/product/B01ABQ5HQY/) - [Analog joystick](https://www.amazon.co.jp/gp/product/B0881LPFKR/) - [Flat cable socket](https://www.amazon.co.jp/gp/product/B07W6KKXCL/) - [Pitch conversion board](https://www.amazon.co.jp/gp/product/B07HQK7H3B/) I created the keycaps using the 3D printer.
