An “USB” charged hair clipper with some quite unusual circuitry …
↓↓↓ Complete description, time index and links below ↓↓↓

I’m still working on the code of the RS-485 protocol for my full fly by wire electric outboard project (link below). So in between I took my old hair clipper apart. It has two power settings, but the PCB has only diodes and resistors on it.

00:00 Intro – busy with coding, so we do a teardown
00:47 Walk around – an oddity and an annoyance
03:36 Teardown – a housing within a shell
14:02 Parts – motor, two PCBs and two NiMH batteries
19:34 PCB reverse engineered – just diodes and resistors
23:03 Wrap-up – next week we’re back to RS-485, bye
