00:00:00.150 --> 00:00:02.990
Hydrogen, with weekly usage at thirty-three percent.

00:00:03.040 --> 00:00:08.356
One prompt: build Ghost Hand, a gadget that keeps a sensor faucet running.

00:00:08.756 --> 00:00:11.887
Sensor faucets fire tiny infrared pulses.

00:00:11.937 --> 00:00:20.370
Ghost Hand echoes each one back on 850 and 940 nanometre LEDs, fooling almost any brand.

00:00:20.770 --> 00:00:25.088
Claude drew the architecture, with the echo path in pure hardware.

00:00:25.488 --> 00:00:31.558
It learns each faucet's timeout, re-arms with the shortest blip, and stops after ten minutes.

00:00:31.958 --> 00:00:39.324
AI Flow builds the board, pulling parts like these tiny WS2812 LEDs from the Adom wiki.

00:00:39.724 --> 00:00:43.034
The main thread spun off a Codex thread for the case,

00:00:43.434 --> 00:00:46.552
and another Claude thread for the dashboard and the wiki.

00:00:46.952 --> 00:00:51.438
Placement lands live in KiCad, part by part, with no mouse.

00:00:51.838 --> 00:00:55.916
Then routing and copper pours, with zero DRC errors.

00:00:56.316 --> 00:00:59.482
Adom Fields checks every amp and every degree.

00:00:59.882 --> 00:01:04.320
The finished molecule: four corner pins seat it in an Adom workcell,

00:01:04.720 --> 00:01:09.926
and snap it into Codex's sealed pebble case, tilted twelve degrees at the faucet.

00:01:10.326 --> 00:01:16.924
The battery is a real Adafruit LiPo, leads plugged in, which caught a reversed connector, now fixed.

00:01:17.324 --> 00:01:21.426
Clear resin light pipes, the main one shaped like the Adom logo,

00:01:21.826 --> 00:01:25.088
and every light named by our UV fiber laser.

00:01:25.488 --> 00:01:30.286
The lights speak only when it matters: set down, plugged in, or low.

00:01:30.686 --> 00:01:33.636
USB-C charges it in about three hours.

00:01:34.036 --> 00:01:37.111
One charge: about nine hundred ten-minute sessions.

00:01:37.161 --> 00:01:38.450
No power button.

00:01:38.850 --> 00:01:45.712
Every part is priced on the public wiki page: about forty-nine dollars for one, twenty-two each for a hundred.

00:01:46.112 --> 00:01:48.572
Why an ATtiny over an STM32?

00:01:48.622 --> 00:01:51.918
It echoes in hardware and sleeps for years.

00:01:52.318 --> 00:01:59.636
Three AI threads, five fixes sent back to AI Flow, and usage went from thirty-three to forty percent.
