Three digit binary clock

Here’s a three digit binary clock that [Viktor] designed. It uses a multiplexed display to drive one digit at a time with a PIC 16F628A. The video after the break shows it ticking away, display hours, minutes, and seconds in blue LEDs. You may be wondering why those LEDs are not flush to the board? [Viktor] took the project one step further than most binary clock projects, designing a PCB to fit into the enclosure of an old laptop PSU and then having the board manufactured. With options like DorkbotPDX groups orders its has become quite inexpensive to do this and it’s really good practice for when you need to design a highly complicated board for that super-fantastic project of the future.
