Our CPSfC Maker Team is starting a harmonograph project. We emailed Wayne Schmitt, a fellow maker who made the harmonograph we are going to replicate, and he emailed us back a list of parts and where to find them. Here is the video he created. http://www.youtube.com/watch?v=HJYvc-ISrf8
Meanwhile, Maggie and Joe are figuring out the parts to the Prusa i3 we are going to make. They are making a list of all the parts on the Prusa i3 so we can open source and build it.
