I will support US/Can type A/B 110 - 120V, European type C 220 – 240 V, England type G 220 – 240 V and Australia/China Type I 220 - 240V power plugs. If your country doesn't support one of these you can power the clock with a 6V power adapter using your specific plug type.
The 15$ reward only includes the circuit board (PCB) with no components and no micro-controller. This is for the advanced makers who have access to the electronic components required to build the circuit.
