Wouldn't those motors be 1RPM? I like that they use a simple AA battery for portability. What I am less sure about is the speed. The motors I mess with are 1/3RPM and the way my lumia discs or bulbs are distorted anything faster would have the effect change too quickly. OF course they are 120V and have to be plugged in which kind of stinks. Could use one of those portable jump start units with a DC to AC converter either seperate or built in.
Wondering about a battery pack for your lab units. What about 3 18650 cells or a few Kongs in series? Just trying to figure out a way to keep it plug free. Then again, I don't know how the lab units will react to a drop in voltage. You could parallel a 100 3 packs of batteries maybe? lol DC to DC regulator?
I guess in general we would pretty much use a lumia setup indoors anyways so the plug thing isn't that big a deal. Still haven't tried my projector outside against the house yet.
Just me rambling... so many posibilities
