This is a Pretty simple project for Double-Double and or Triple-Triple-Triple checking a PCB layout.

I Recessed Magnets make it so you can stick it too any Whiteboard for storage. Make a few and colour coat them with electrical tape. I find it useful to have more then one when I have more then one ongoing project.

It kinda looks like how scientists used to pin up Dead Bugs for specifying differences in species, but it is a pinned circuit. I find that it is very useful not just for designing. But being able to Visual the circuit board.

Learned this Tip from Ben Heck a YouTube Console modded “DO it on paper first, PCB material ain’t cheap”
