BenchSight is a hands-free AI copilot for laptop motherboard repair, built for Ray-Ban Meta glasses. My family runs a computer sales and repair shop in Suryapet, Telangana. In small shops like ours, a board that needs one cheap part is often scrapped because the technician can't trace the fault: there's no schematic, both hands hold multimeter probes, and the know-how lives in a few experienced heads.

The technician looks at the board. BenchSight reads the board ID and asks him to confirm it. Then it asks for one multimeter reading at a time, out loud, in Telugu, Tamil, Hindi or English: meter mode, where the probes go, power state and the expected range. Every reading is logged as evidence and rated normal or abnormal in code. Before any diagnosis, code checks the evidence and a separate Muse Spark judge reviews it. After three failed checks it escalates to a human instead of guessing, and nothing counts as fixed until the technician signs off.

Built during the hackathon: a Python diagnosis server, an Android glasses client (Meta Wearables Device Access Toolkit with the Mock Device Kit), a laptop test bench that logs every Meta model call live, and a judge mode that replays recorded sessions without an API key. Tested at a real repair shop on an HP board with no display: the technician said his own reading, "19.5 volts at the jack… skip the basics", and BenchSight logged it as normal and moved straight to the 3.3 V standby rail.
