I made this together with a friend! as a birthday present. It counts down to the next big Steam sale. It is connected to wifi, so it will always request the right time. It is made using a NodeMCU microcontroller. 7 segment displays, Shift registers, a 3d printed case and a lot of wires. Took about 80 hours to design, make and test. And the whole thing is only 25 euro’s(30 dolars at the time of writing).

hope you like it.
