Just finished up a simple test rig. I've put it off long enough and I'm terrible at troubleshooting, so I figure if I could at least get the finished PCB to work then the troubleshooting will be limited to the box or forgetting something obvious.
I used a box I had made up for a build that doesn't work (yet!) The wood is a $4 item from Michael's. Some stamps for labeling. I got to use one of the battery holders I bought before I stopped putting batteries in pedals. And...I left room for a breadboard! Just tested a Cave Dweller and an Egodriver...successfully :D
Very happy with how this build turned out.
