My agent listed every empty course before the semester and caught one open too early

He directs academic tech at a university. Every semester some instructors never set up their courses, so students walk into empty course pages. A day after signing up, he had the AI build a CSV of upcoming courses with no content, or where the instructor has never entered the course. The list also told him one course was already open to students when courses should not be open yet, so he closed it.

An agent reverse engineered his old modem and got modern OpenWRT running on it

A man had an obscure Alcatel modem with undocumented hardware. He soldered on serial pins, plugged it in, and asked an agent to reverse engineer the firmware. DeepSeek v4.1 Flash took about an hour to get a full OpenWRT build and flash pipeline running in an isolated container, the driver changes worked, and the whole job took under half a day and $0.86 in AI cost, work he says would have taken weeks or months.

The AI made my adapter bracket in one shot

He gave the AI a CAD file he could not even open, plus a few measurements he took with digital calipers. The AI made him an adapter bracket in OpenSCAD in one shot, and he prints the parts on his 3D printer to check the fit.
