Pocket AOI finds assembly mistakes on a circuit board from one photo, and says what each mistake will break. In student labs, a reversed capacitor, a backwards IC or a missing resistor costs more debugging time than design errors, and factory inspection machines cost tens of thousands of dollars.

You photograph one correct board once, then compare each test photo with it. The report marks each fault on the photo, shows a safe-to-power banner, and gives each fault a card explaining its effect, written from the board's netlist.

On 134 real photos of four boards from the public VisA dataset, taken with a fixed camera, it flagged 60 of 70 defects on the board and named the right type for 46. A further 24 defects outside the board's outline are not counted, and 9 of those were flagged. About 2 false alarms per clean photo remain. In a separate test it confirmed only 8 of 24 reversed parts, so the report never calls a board safe. Handheld phone photos of through-hole kits are still untested.

All project code was built during the hackathon, with the first commit on 3 Nov 2026. The README lists what was built and what was not.
