John Lauer First AI PCB with Grok: clip 6, Grok's first molecule 426f6e0 5d ago
1
00:00:00,000 --> 00:00:03,400
One correction: Adom boards follow the
molecule standard.

2
00:00:03,610 --> 00:00:12,200
So Grok reworked its board on its own
computer: machine pins in all four
corners, machine contacts on the edges
instead of screw terminals, everything on
a 2 mm grid, and a 36 by 20 mm outline
with rounded corners.

3
00:00:12,440 --> 00:00:14,400
Grok added an enable contact so the
control panel can switch it off.

4
00:00:14,600 --> 00:00:22,700
Adom Fields found a real neck where the 5
V output entered its contact: 85 A/mm² on
a thin ring.

5
00:00:22,890 --> 00:00:30,600
Grok widened the copper and added vias,
and it dropped to 9.

6
00:00:30,770 --> 00:00:34,550
Here is the current flowing through the
new copper.

7
00:00:34,740 --> 00:00:39,000
With half the copper area, U1 now rises 24
°C, still under its 40 °C budget.

8
00:00:39,030 --> 00:00:46,100
EMC margin holds at 48 dB, and both rails
pass.

9
00:00:46,280 --> 00:00:47,800
Four low issues remain.

10
00:00:47,980 --> 00:00:51,050
Grok's first molecule.
