Just had a really crazy idea, use the laser cutter to create a CPU in fluidic logic!Fluidic logic has no moving parts except the fluid and looks to be really cool but may not be practical. More conventionalfluid logic with a moving part may work better but is rather more work to make.
I've seen physical designs (with identical equations actually) for
capacitors, resistors, inductors, and transistors. I think they could
probably all be made laser-cut with some additional components (e.g.
rubber sheet for capacitors), hinges for transistors.
