You're right, and, in addition to being the creator of this vacuum (which I designed in a few hours), I'm a core developer of the hacklab-reprap (https://github.com/hacklabto/Hacklab-RepRap; you can see my last update on it at http://christopherolah.wordpress.com/2011/01/24/hacklab-repr... ). Unfortunately, I can't focus on that 24/7 and occasionally work on other projects...
