Jason LED Nameplate

A USB-C-powered desk decoration that spells JASON in green LEDs — twice the size of Scott's nameplate.

What's on the board

160 × 76 mm Adom molecule (2× Scott's footprint)
~56 green 0603 LEDs forming a 3×5 bitmap of each letter at 6 mm pixel pitch
One 300 Ω 0402 current-limit resistor per LED (≈10 mA each → ~560 mA / 2.8 W total)
USB-C TYPE-C-31-M-12 receptacle on the south edge (J1, JLCPCB C165948)
5.1 kΩ CC pulldowns (R_CC1, R_CC2)
10 µF X5R bulk decoupling cap (C_BULK)
4 corner machine-contact pins (MC1–MC4) for workcell fixturing

Powering it

Plug any USB-C cable into the south edge — phone charger, laptop charger, anything 5 V. The letters light up.

How it was built

Authored in tscircuit (TSX, see source bundle). Published to the wiki with adom-tsci export-wiki so the live 3D viewer (orbit, x-ray, walkthrough) is embedded right on this page.
