Jason Chua Yap has been working hard to make these kits available to those of you who don't have access to a 3D printer and who want to take advantage of bulk rates. He has just about all the parts ready to go (just waiting on the Arduinos and breadboards). He expects everything to be here by the end of the week and the kits to be shipped by the end of next week. He ordered enough parts for a few extra kits, so if you're interested, send him an email: jyapchua@gmail.com.
