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.

Rev 2 UV fiber laser engraving
laser_engrave.svg uses real millimetres and four independently registered face groups: top, front, right and bottom. Black filled paths are engraving. Red 0.05 mm lines and circles are registration guides only; disable red before firing. All lettering is converted to closed vector paths; no installed font is required by the laser software. No logo.
Top: five 1.5 mm dot registration circles, STATUS, 25/50/75/100 and a small GHOST HAND wordmark. Front: IR. Right: USB-C 5V. Bottom: product/revision, MIT, battery rating and the complete stop-condition statement split across two lines.
Engrave each face in its own jig. Top coordinates are a plan projection of the crowned roof; the crown changes focus across its 32 mm depth, so use the machine's height compensation or separately focus small fields. Confirm actual printed dot positions against the red registration layer. Front/right drawings are face-registration rectangles, not wraparound toolpaths. The SVG bottom is viewed from outside the bottom, after flipping the part about X; mirror the jig axes as required, never mirror the readable text.
Mask the optical faces and gasket seats. Use a matching material coupon to establish UV power, hatch and scan speed; the design does not prescribe universal laser settings. Engrave shallowly, clean away residue, and seal the printed exterior afterward if its coating process requires it. Do not engrave an assembled device containing a battery.
Interface rev B: STATUS at board (11, 7); gauge at X=11.3, 14.5, 17.7, 20.9 and Y=15.5, 3.2 mm pitch. Registration circles use the pitched pipe axes at the roof, including their shift with height.
