# Taiko-stick / 电子太鼓槌
|
|
|
|
A pair of drumsticks that can be used to play Taiko no Tatsujin on any surface.
|
|
|
|
一对可以在任何表面上打太鼓达人的鼓槌.
|
|
|
|
## 1. Build / 制作
|
|
|
|
### Materials Required / 材料
|
|
|
|
* 2x Thick-enough drumsticks [$16]
|
|
(The one I used: [taobao link](https://item.taobao.com/item.htm?id=665108049486))
|
|
* 2x Piezo sensors (压电/蜂鸣陶瓷片) [$2]
|
|
* 2x 1MΩ resistors [$0.3]
|
|
* 1x Arduino Nano 328p [$3]
|
|
(or any other dev board, just change the platformio config)
|
|
* Many wires
|
|
|
|
Note: The prices above are in CAD, but I bought many of them from China (e.g. drumsticks). If you don't understand Chinese or is not used to international shopping from Taobao, these components be more expensive to buy locally.
|
|
|
|
### Tools Required / 工具
|
|
|
|
* Either a breadboard, SPL2 solder-less connectors, or a soldering kit
|
|
* A computer
|
|
|
|
### Connections / 连接
|
|
|
|
1. Glue piezo sensors to the drumstick
|
|
2. Connect the ground of each sensor to the ground
|
|
3. Connect the output of one sensor to A0 and another to A1.
|
|
4. Connect 1M resistors between ground and the sensor outputs, one for each sensor.
|
|
|
|
> If you want to protect the ADC from high voltages that the sensor might generate, you can connect an extra 5.1v zener diode in reverse bias from ground to each sensor
|
|
> so that voltages flowing to the ADC will be at most 5.1v.
|
|
|
|
|
|
|
|
## 2. Run / 运行
|
|
|
|
### Flash Firmware / 烧录固件
|
|
|
|
1. Install PlatformIO Core ([Guide](https://platformio.org/install/cli))
|
|
2. Connect the Arduino Nano to your computer
|
|
3. 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.
|
|
|
|
1. Install Python 3.11+ ([Guide](https://www.python.org/downloads/))
|
|
2. Install dependencies using `pip install -r requirements.txt`
|
|
3. Run `python reader.py`
|
|
4. 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.
