I built a simple, single-portion programmable cat feeder in about four days using rapid prototyping. I describe the Fusion360 sizing, plywood shell, servo mechanism, electronics, and the issues I encountered with breakout boards. If you're curious, read the full post for parts list, wiring and source code.

I've just finished Part 2 of the Outmoded Sequencer project, sharing the journey from prototype to final device. I explain the custom PCB work, lessons learned (including unreliable steel-ball matrix switches), and practical recommendations. If you're curious, please read the full post for build tips and cautions.
