Introduction
One of my sons recently started to nag me. He wanted to solder something. Initially I had no idea what he could solder and I thought he was simply bored. But he kept going and I knew I had to find something. Finally I remembered that it would be "Blue Night" soon and that I wanted to take my kids there. So we could build some coloured light object to be worn at the event.
I looked through my unused hoard of components and found the bag with one hundred rainbow LEDs (i.e. slow colour changing LEDs). I had ordered them from China for little money - for no good reason really...
And so was born the idea to build a little pendant of 3x3 LEDs.
