1. Build / 制作

Materials Required / 材料

2x Thick-enough drumsticks
(The one I used: taobao link)
2x Piezo sensors (压电/蜂鸣陶瓷片)
2x 1MΩ resistors
1x Arduino Nano
(or any other dev board, just change the platformio config)
Many wires

Tools Required / 工具

Either a breadboard, SPL2 solder-less connectors, or a soldering kit
A computer

Connections / 连接

2. Run / 运行

Flash Firmware / 烧录固件

Install PlatformIO Core (Guide)
Connect the Arduino Nano to your computer
Upload firmware using platformio run --target upload

Run Backend / 运行后端

I'm too lazy to write a HID device driver, so I'm using a python script to read the serial output from the Arduino and send keystrokes to the computer.

Install Python 3.11+ (Guide)
Install dependencies using pip install -r requirements.txt
Run python reader.py
Use Ctrl+C to exit.

Note: If you're using osu-stable, you might want to change the key settings either in the python script or in the game. By default, the script uses F for don and D for ka.
