Hacking chinese USB volume controller into Arduino compatible board

Other Hardware Device Hacking

You can find pretty cheap devices like this and also this.

What makes them even more interesting is the fact that the built-in microcontroller is an ATmega32u2. You can get a bootloader for this chip here.

And to make it even simpler to mod these, I've created some helper library to support the built-in hardware:

All required libraries are already in the Arduino library manager.
My GitHub page has some instructions on how to mod the board.

My library comes with a few examples.

Please post your own "rotary encoder project ideas" here :slight_smile:

Somebody is going to ask this anyway soon, so... did ask a permission to use those pictures on your github site, or are they public domain?

Anyway, they are very useful devices. Dirty expensive too. Let's see where this goes.

I bought those devices, arranged them and took the photo with my camera.

So I think it's OK that I use my photo on my GitHub page.

Very cool! I might try to program one as a jog/shuttle knob for video cutting.
