Ask HN: What are some great ESP32 DIY pojects for Xmas gifts

I'm getting into electronic hobby projects. I would really like to learn how to design PCBs, and work with verilog and FPGA. For now, I've ordered a bunch of ESP32. I would like to take the Holidays as an opportunity to do a few beginner/intermediate projects using the ESP32, I would like the projects to help me learn to pinning in, soldering, using breakout boards ect ect. Are their any cool Christmas gifts I can DIY with ESP32 that would also be great learning opportunities?
