Inside a ceiling fan/light with ARM Cortex MCU
Added 2025-09-19 23:44:19 +0000 UTCAfter seeing the BBC run a media campaign against these devices, I decided to get some to take apart. The circuitry is actually quite impressive.
This is the full length version of the video. I also made a shorter version for those who don't like the full schematics. It will be released around the same time.
Comments
Unrelated to the fan light but pertaining to the "USB lighter" you mentioned a little while ago, I ordered one and thought it didn't work until I took it apart and found a microphone like pressure sensor inside. Blowing into the lighter will turn it on to heat up. :-)
