Night Hack × HeyPCB.
Ask your coding agent for a circuit board, and HeyPCB designs it as a real KiCad project. Attendees get a month of Starter free. The 3 winners get their boards made.

Starter is on your account. Your boards are in your dashboard.
Start in one paste.
Pick your agent, copy its line and paste it. Your agent can then design boards with HeyPCB.

Your first prompt
Then paste this into your agent.
Your agent sends the brief to HeyPCB, which picks real parts, places and routes the board, and checks it. You get a link to the files a board house needs.
Use HeyPCB to design a small ESP32-S3 sensor board: USB-C for power and programming, a BME280 temperature, humidity and pressure sensor, a status LED, and BOOT and RESET buttons. When it is built, check it until it is ready to order, then export the files for JLCPCB and give me the download link.
On October 27, Claude Code had this board ready to order in 25 minutes. Your agent may go quiet while it works.
Every client HeyPCB works with is on the MCP server page.
What you can build tonight.
