Ghost Hand
Public Unreviewedby John Lauer
A small battery gadget that keeps an automatic sink faucet running while you use the sink: it learns the faucet's timeout, re-arms with the shortest blip, and stops after 10 minutes or when picked up.

The roof follows the board's 12 degree nose-up pitch, so drips run off toward the back and the dark front window aims the IR up at the faucet's sensor, with separate transmit and receive openings and an opaque barrier between them. The board's four machine pins press into split printed collets that squeeze them, the same pins that seat it in an Adom workcell. The LiPo lies flat under the board on its own spacer, which also holds an optional steel ballast plate. A TPU gasket seals the seam, a tethered TPU stopper seals the USB-C tunnel, every screw enters from below through a TPU seal, and a TPU ring is the non-slip foot. Five clear-resin light pipes carry the WS2812 lights to the top: the main one is the Adom logo and four pills make the battery gauge. A UV fiber laser engraves the light names on the case.
