I wanted to make a little clock for my desk at work. A night I saw Iron Man 1 again and I thought : “great scott ! What about an Iron Man Arc Reactor clock ?!”

You can power it either with a phone power supply or directly from your computer’s USB port. The ESP32 I used is a standard micro-usb, so you can use a simple cble USB - Micro USB.
I used black and transparent PLA to make the differents parts.
Hope you’ll enjoy to make it !

The components :

- 1x Led ring
- 1x Mini ESP32
- 1x Blue display
- 2x blue leds
- 2x 47 Ohms resistors
- 10m Copper wire
- wires
- 3x screws 3x10 mm”
