This looks cool (haha). Is it apparent to anyone how it's powered? The article says "The fan’s power cables are soldered on to the step-up converter. The step-up converter is powered by the USB power supply.", but it's not clear to me where the power supply gets the power it supplies.

- londons_explore 7y agoThe lamp is mains AC, and is only powered when the door is on.
- d2wa 7y agoI'm the author. I've updated the article to clarify. It's powered by a 220/110V USB power supply outside the fridge, USB micro cable in through the door seal, and then the 5V/12V-converter lives inside the fridge. The converter is also used to adjust the speed of the fan.
