DIY Stomp Box / Foot Drum... NEW version 4.1!

A few years ago I made a stompbox / porchboard / foot percussion thingy. It worked but I kept tweaking and I think I'm ready to show off the new version (fourth version) since I've been pretty happy with it.

If you want to make something like this yourself, most of the components can be found easily on Amazon, but here's a link to the specific Electret Mic module I used:

None of the components are expensive, but if this is your first electrical engineering rodeo, then the cost of tools, etc. can add up.
