Steven's nameplate

A desk nameplate for Steven Moss of the Astera Institute, built three ways. Each revision is a small experiment with its own question, method, result and files, published the day it was made. The failures stay on the page next to the fixes.

This is Rev 2, loaded when it scrolls into view. The guided walkthrough starts on its own; the PCB, Schematic and Parts tabs are live. Open it full screen.

Why three revisions. Rev 1 worked electrically but its N read as an H. Rev 2 fixed the font and moved to real, stocked part numbers. Rev 3 asked a different question: skip the per-person circuit entirely, and laser the name into one standard LED-lit board. That is the plate Steven will hold at the NSF PCLNet Summit in DC.

The three revisions

Rev 1: 3 x 5 LED dot matrix

Rev 1: 3 x 5 LED dot matrixsuperseded

58 white LEDs spell STEVEN, powered from an iPhone charger. 0 DRC errors and every net connected after a layout sweep that is documented in full, including the router's silent opens. Failed as typography: three columns cannot draw an N.

Rev 2: 5 x 7 LED dot matrix

Rev 2: 5 x 7 LED dot matrixdesigned

94 white LEDs in a 5 x 7 font, so the N has a real diagonal. Every part is a stocked Adom Basic Part with an MPN, the draw is about 400 mA, and the board resizes itself from one line of text. 0 DRC errors, 98 of 98 nets connected.

Rev 3: name laser-ablated into the silkscreen

Rev 3: name laser-ablated into the silkscreenmade

The plate Steven receives. Adonis Lysandrou's standard blank board (Fusion 360, six side-firing LEDs), with "Steven Moss" on the first line and the Astera logo on the second, ablated into the soldermask by the workcell's UV laser from a Nameplate Generator job. Per-person work drops from a new PCB to a laser job.

Open science

This page is a worked example, for the Astera Institute, of how Adom's AI publishes an experiment as soon as it exists. The full scorecard lists every rule and where this page meets it, meets it partly, or does not yet.

Provenance

Requested by John Lauer (PI, Adom Industries, NSF PCL Test Bed node, Fort Worth). Revs 1 and 2 designed by Claude (Anthropic) in Adom's Hydrogen desktop with tscircuit and adom-tsci. Rev 3 board designed and ablated by Adonis Lysandrou; laser job generator by Aditya Angajala. The node is funded by the U.S. National Science Foundation (ROR 021nxhr62). Made for the Astera Institute (ROR 00ydx1s47), which did not fund it.
