The AI designed his fan controller circuit, board, and software. The boards are ordered and still untested.
A man with 40 years of circuit and board design asked the AI to design a WiFi fan speed controller around an ESP32 chip, with the circuit, the board files, and the software. The first design took about 15 or 20 minutes. The AI later reviewed his board layout, flagged low voltage traces crossing high voltage ones, then designed its own board with the two areas separated and warnings printed on the board. He bought the parts himself. The boards are on their way and have not been powered up yet.
This only partly worked. Read what happened before you try it.
How it works
- He names the chip, the circuit shape, and the tools to use
- The AI designs the circuit and picks the parts in about 15 or 20 minutes
- He gives the AI photos of the project case from a store page and the AI makes the board outline with mounting holes
- The AI reviews his board layout and flags mains safety problems
- At his direction the AI designs its own board with high and low voltage areas separated and warnings printed on it
- The AI writes all the controller software, including a web page to set fan speed
- He buys the parts himself
Why it’s worth knowing
The agent's own board layout beat the layout of a man who has done this work for 40 years, on the safety point that matters most with mains power.
