Colour changing 24Hr Binary clock using ping pong balls and full colour LED’s and a Funduino 88 matrix board. I have already built a small 12Hr binary clock and fitted it into a computer, this worked very well but was only really half a binary clock (no seconds). So I decided to build a full 24hour with second’s binary clock. As I was designing the clock I decided to try and make it very colourful and pleasant to look at, so I choose full colour LED’s and used ping pong balls to make a nice diffuser! At this stage I hadn’t really thought about how I was going to drive the LED’s I initially thought about using logic gates linked to the PWM pins of the Arduino, but the more I thought about it the more difficult it was. Basically I have 20 5mm full colour LED’s, meaning I have 60 LED’s in total. so at this point I had another think about how I was going to drive all the LED’s and then realised I had the solution in a 88 full colour matrix, I had already used a Funduino/colorduino when I made my Plasma box, so this was a logical solution.”
