Active Pickguard project for Kinetis Challenge

Eli Hughes made this awesome PCB pickguard for his entry in the Freescale Kinetis Make It Challenge. It contains a Freescale Kinetis ARM Cortex M4 processor with DSP extensions to process the guitar signal, providing both an analog and digital audio output.

He also release a video with the details of all the maths and physics explained, as well as the hardware design.

Code and schematics are available here.
