We like a Marvel prop, and we like knowing what time it is, so we love this clock built into an Iron Man-style arc reactor. Based heavily on the work of YR3Design, this clock by Jégé l’ingé is a masterpiece of 3D-printed snap-to-fit parts, held together with glue and a bit of decorative copper wire. It’s connected to the internet via an ESP32, and uses an RGB LED ring plus a pair of blue LEDs to light up the clock display in the centre of the ring.
It’ll take power either from a phone charger or from a computer’s USB port, and it flashes every time an hour passes. Marvel-lous!
