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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
