There are a lot of "plugin" capacitance sensors for prefab boards (the Teensy 3 even comes with 12 cap sensors built in). However, basically all of them look like they are using oscillators to measure which can take a longer than is desirable in this use case (the Teensy's take about 3ms to measure ...

Thanks! The linked pdf explains it pretty well.

I just started following this project today and read the project is currently developing this redesigned custom board. Here's a stupid question since I am a software dev and not an engineer: If the only necessary interface is 30pin -> logic -> usb, why not use a RPi zero instead of a custom board: h...
