Binary Clock


Short build-lapse video of building up the front panel “matrix” used in BinBoo.  This isn’t a true LED matrix.  Instead it combining all of the LEDs into a common Anode, since the Cathodes are all controlled by individual outputs of the TLC5940. I decided to wire up 16 LEDs, even though a binary clock only needs 11 or 12.  This gives some flexibility to other uses for the box, like a random sci-fi computer pattern.…

Several months ago I started a project to build a Binary Clock, using a Laser Cut enclosure.  The plan was to use Ponoko’s laser cutting service.  Looking through the materials available, I decided to use Bamboo.  Knowing I was going to build a Bamboo enclosure for a Binary clock, helped me come to the name BinBoo.  Even though I call it a Binary Clock, it is actually a BCD clock… There are still a few…

Control Board with LEDs by JamesC4S

The control board is up and running, with some re-work. Shown next to the working LEDs is my original inspiration.  Last Christmas my brother gave me the ThinkGeek Binary watch.  Since then I’ve been fascinated with binary clocks.  Finally I had an idea that can help with other projects.

Untitled, a photo by JamesC4S on Flickr. Assembled control board. The processor is an ATmega328, RTC is DS1307 RTC, and LED driver is a TLC5904. There is also a FT232RL on the back side for USB to Serial connection, however, it doesn’t appear to be working.Next I’ll need to turn on the RTC and make sure it can actually keep time.
