Ghost Hand

Public Unreviewed

by 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.

   "description_full": "Ghost Hand rev 2's board: an Adom molecule (30 x 22 mm, 2 layers, parts on both sides, 4 corner machine pins) that keeps an automatic sink faucet running. Side-looking 850 and 940 nm IR emitters and two PIN photodiodes echo the faucet's own interrogation pulse; an ATtiny1616 learns the faucet's timeout; a 150 mAh LiPo charges over USB-C at 77 mA; five WS2812B-2020 dots show status and charge.\n\nEvery part of this board (from the Adom wiki and the board's project library): symbol, footprint and STEP model.
