Thingiverse
This is a high resolution rotary device. Powererd by a 32u4 (Pro Micro) microcontroller, which supports USB HID. This means the controller can be freely programmed via the Arduino IDE to work with any HID copatible device.Build cost around €10-15 (see component list)Video:https://youtube.com/shorts/Ty42Z4h6TcQThe device only works via cable. It would be possible to add a Bluetooth module and a battery, but in my opinion that makes the device far too complex for a DIY project. There would also be several technical challenges involved in making it wireless.As of now the device is configured as a surface dial device. This unlocks surface dial functionality in Windows.I have only tested this device in Windows!The dial can be reprogrammed easily for Linux or macOS, but it won’t support high‑resolution scrolling because I haven’t figured out how to set up the correct HID descriptors. I also don’t plan to invest much time in figuring that out.
