Argon video: review draft

The working cut of the YouTube video "Can Gemini 4 Argon Design a PCB?". It is complete except for John's voiceover, and it is here for review and for recording that voiceover. When the final video is ready it replaces this one in place.

  • Length: 5:51
  • On YouTube: unlisted draft, with the drafted title, description, chapters, thumbnail and English subtitles
  • Title: Can Gemini 4 Argon Design a PCB?

The drafted description

Our CEO John gave Gemini 4 Argon one sentence, and it designed a 12 V to 5 V, 1 A buck converter on the TI TPS54202 in KiCad, inside Adom Hydrogen, for about $2.59 of AI.

Argon runs in Google Antigravity inside Hydrogen and follows adom-aiflow's 25 steps: design rules, circuit math from the datasheet, in-stock parts, a 38-symbol schematic with 0 ERC errors, SPICE, then placement and routing through the Adom KiCad Bridge. The current and thermal checks sent it back 4 times to fix the copper, and Adom Fields solved the finished board, including an EMC screen with 56 dB of margin against FCC Class B. The result is a 28 x 20 mm 2-layer board with 0 DRC errors, from 1,169 model calls and 5.6 % of a week of Google AI Ultra.

The full description, with the project links, the prompt, the links to Parts 1 and 2 and the chapters, is on the YouTube draft.

Still to do

  1. Voiceover. John records his narration to replace the adom-tts voice.
  2. John's edits. Any other changes from John's review.
  3. Release. The plan is to publish on Friday, then premiere Noah's video on Saturday.
