I made one too, it's really easy to do with the Arduino. Hope you can get enough resources to build your own, it's a fun project. (mine was slower than a normal POV so I could write in longer exposure photographs, but you can easily change the delay to make it faster/slower as you want). If you want code I can post it
k2pek2 - Liked your project... I would like to see your code if your willing?
