In this case, [Jeremy Cook] put one to work as the faceplate for his “742 Clock,” a name that plays on the fact that his seven-segment display is 42 mm tall, plus it’s “24/7” backward.

The circuit in Fig. 1 is a 12-V/5-A digital power converter that is easy to build and uses the parts list shown in Table 1. It has a minimum number of robust parts with simple interfaces.

The first is the clock circuit. The clock runs off a PIC microcontroller with a 4MHz crystal. All of the logic is performed via the PIC and only a handful of other components are required.

The Ground is odd, but the +/- 1.5V appears with your image that it makes a total 3V circuit/battery, but the board only needs 1.5V to function.
