What you'll build
Build a board that moves a hobby servo on command over PWM. The interesting part isn't the signal — it's the power: a stalling servo can brown out your microcontroller and reset it mid-move. You'll design around that with a separate supply rail, a bulk capacitor sized for the stall current, and wide, short high-current traces.
It sits on the ACT track: driving the physical world with motors, servos, and high-power lighting under precise control.
Tools for this build
Free calculators that do the math this board needs. Each is worked from a real OTD board, with the formula and a cited source.
The build pipeline
No steps skipped, no black boxes. Each stage is gated on real proof of work: a clean ERC, valid gerbers, a passing bring-up. You finish having actually done the engineering, not just watched it.
