Thanks for a great description, I've been thinking of doing something similar for quite a while and have the electronics and transformer. Do you have any idea if it's possible to use multiple windings of thinner wire in parallel for the secondary coil (e.g. 15A mains cable)?

Wasn't my intention at all, and I sorry if it was construed that way. I don't think it's a loose connection at all (especially since jprussack asked specifically for the force calculation). By spinning something around like this a force (greater than the force due to gravity) will be in effect on the water droplets allowing the surface tension to be overcome. Effectively, the water becomes 25 - 30 times heavier than normal.

If I recall correctly, the force is mass × angular velocity squared × radius. More interesting would be the acceleration (ignore the mass) - as this could be compared with acceleration due to gravity (9.8) to see how many times more effective this would be than 'drip drying'.

Absolutely fascinating! I've been considering learning about SDRs, so to see a usage including both the hardware and software side is great.

Very interesting instructable. Do you happen to know what torque you can achieve with this particular motor?
