A great little gift I got for Christmas was a persistence of vision kit from Make Magazine which has a simple micro controller that controls 8 LEDs. It comes completely unassembled and you need to solder all the pieces on the circuit board. This was my first time doing something like this, but I found it quite easy especially with my new soldering station. I programmed the kit to say “Julia” since my daughter wanted to show it off at school.
Then it occurred to me that it would be fun to try to build a lego mindstorms robot that spun the MiniPOV around fast enough to get the wanted effect. You can see the results in the photo album. It doesn’t work great since it does not rotate fast enough for the naked eye to see the effect, but the camera captured it. If I gear it up higher, then the motor does not have the torque to turn it. Still, it was a very fun project and we had a blast building this.
