1
00:00:00,150 --> 00:00:02,990
Hydrogen, with weekly usage at thirty-three percent.

2
00:00:03,040 --> 00:00:08,356
One prompt: build Ghost Hand, a gadget that keeps a sensor faucet running.

3
00:00:08,756 --> 00:00:11,887
Sensor faucets fire tiny infrared pulses.

4
00:00:11,937 --> 00:00:20,370
Ghost Hand echoes each one back on 850 and 940 nanometre LEDs, fooling almost any brand.

5
00:00:20,770 --> 00:00:25,088
Claude drew the architecture, with the echo path in pure hardware.

6
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.

7
00:00:31,958 --> 00:00:39,324
AI Flow builds the board, pulling parts like these tiny WS2812 LEDs from the Adom wiki.

8
00:00:39,724 --> 00:00:43,034
The main thread spun off a Codex thread for the case,

9
00:00:43,434 --> 00:00:46,552
and another Claude thread for the dashboard and the wiki.

10
00:00:46,952 --> 00:00:51,438
Placement lands live in KiCad, part by part, with no mouse.

11
00:00:51,838 --> 00:00:55,916
Then routing and copper pours, with zero DRC errors.

12
00:00:56,316 --> 00:00:59,482
Adom Fields checks every amp and every degree.

13
00:00:59,882 --> 00:01:04,320
The finished molecule: four corner pins seat it in an Adom workcell,

14
00:01:04,720 --> 00:01:09,926
and snap it into Codex's sealed pebble case, tilted twelve degrees at the faucet.

15
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.

16
00:01:17,324 --> 00:01:21,426
Clear resin light pipes, the main one shaped like the Adom logo,

17
00:01:21,826 --> 00:01:25,088
and every light named by our UV fiber laser.

18
00:01:25,488 --> 00:01:30,286
The lights speak only when it matters: set down, plugged in, or low.

19
00:01:30,686 --> 00:01:33,636
USB-C charges it in about three hours.

20
00:01:34,036 --> 00:01:37,111
One charge: about nine hundred ten-minute sessions.

21
00:01:37,161 --> 00:01:38,450
No power button.

22
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.

23
00:01:46,112 --> 00:01:48,572
Why an ATtiny over an STM32?

24
00:01:48,622 --> 00:01:51,918
It echoes in hardware and sleeps for years.

25
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.
