He let Claude design a complete e-ink business card, from schematic to product page
isaul32 · reddit · 2026-10-27
The author had Claude do the schematic, PCB layout, 3D-printed case, product video and product page for a credit-card-size e-ink business card (RP2040, USB-C, 2.9" e-ink, optional LiPo with charger), only specifying requirements and reviewing the work. The board hasn't been fabricated yet. The product page publishes the schematic, layers, BOM and Gerbers, plus a how-it-was-made section with time, tokens and cost — a rare look at an AI agent's limits in real hardware engineering.
