A barebones guitar amp that should run on any device with audio input & output. See the "Note" section below before use.
This was just intended for a little side-project with my family, and I wouldn't recommend using it in the wild as-is. More specifically, this ran on a Raspberry Pi Zero W, connected to a Guitar (via USB) and speaker (via bluetooth) as described below.
If you do wish to adapt this to your own setup, feel free to open an issue if you need any help with it.
- Guitar (1/4 inch Jack) --> USB
- Using this adapter
- USB --> Micro USB
- Using this adapter
- Micro USB --> Raspberry Pi Zero W data port
- Raspberry Pi Zero W --> Speaker
- This bluetooth speaker was paired with the Pi for testing
- Could potentially be done via USB or GPIO pins as well
