Here is an interesting LED binary clock by instructables user ElevenOf9. I really like the single sided PCB, and the way the LEDs are arranged. It just looks cool!
This is the second revision of my PIC based LED binary clock. The original version was the first PIC project I attempted, it used a PIC16F84A to do both the timekeeping and control the display matrix, unfortunately it didn’t keep good enough time and gained about a minute every week.
