The Countdown to Maker Faire Bay Area is On!


LED Binary Clock

LED Binary Clock

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.

    This is an interesting binary clock, but one of the most original ones I’ve seen in a long time was designed by Roman Black, an Australian. The details can be found over at with both pcb layout and code available for download. There’s even a version for Windows…
