My build process goes in phases (usually), especially when it comes to enclosures, which is what I've been focused on lately - I usually work on drilling/finishing 3-4 cases at a time. The Electrovibe is in this batch - I started drilling, then saw the LED holes in the faceplate.
I haven't started the PCB build yet, but I'm likely going to use a prescription pill bottle (cut down) with something reflective adhered to the inside, as a light shield.
My previous vibe was a Hollis Easyvibe, which uses four individual LED+photocell couplers. I'm rebuilding that for my cousin.
I'll post something when it's done.
Thx!
