I built a portable meshtastic terminal using Claude and a Pico 2. It's written 100% of the code in MicroPython and it works great. It even wrote the driver for the E-ink screen I'm using. I built a jig to hold a webcam and the e-ink screen, then had Claude write a script/MCP that takes a photo and crops just the screen out. Then I asked it to figure out a driver, and after a 20 minute loop of taking photos and updating it's driver, it was done.
