Electronics Lab: Lots of fun!
The Stupid Pet Trick plan:
A game board like the old Operation, but instead teaching you about where different cuts of meat come from in a cow. Ideally I could actually cut the holes over where different primals come from and put in labeled pieces.
Key elements: Metal tweezers and metal-coated game board work like an off/on switch, which will trigger a piezo and a light when the circuit is completed.
To do: Design a cow board, cut with laser cutter, make metal frame.
