Reclaimer Labs does some great USB-C work and posted a hack to power a child’s Easy Bake oven from a USB-C power port:
I modified an Easy Bake Oven to run off USB-C. The obvious question is “Why?”, but I prefer to ask, “Why Not?”. The USB-C spec allows for 100 Watts of power to be transferred through the connector, and that is the power rating for the oven, so it should work. I found one of the new models of the Easy Bake Oven on Amazon.
Reclaimer uses their USB-C breakout board to get the power broken out. Check out their Tindie store for this and a nifty USB-C Explorer board.
The code I used is the library I’ve been porting from Google’s Chromebook open source repository. I set the max allowed voltage for my board to 20V and the max power to 100,000,000 microWatts (100W), so it will request everything the charger can provide. I also programmed the Arduino to flash the light at startup, turn it off while USB-C negotiation was ongoing, then turn it on when it successfully negotiated for at least 75W.
