Here's a question why does a rotary machine need a special power supply, the Remote Control helicopter and speed boat guys have been using dc motors to power their gadgets for years with out any special power supply. I would be careful about being conned into buying the latest power supply just because some company says you need it. I want to see some stats first like adds extra torque to a standard motor, something that can be physically measured.

I know there is a guy from New Zealand that produces a pulse unit that plugs into your power supply. Then you can adjust the amount of pulses and length of the pulse this is great for smoothing out old power units or cheaper ones but this type of unit works best with a coil machine. If someone has some data on pulsing power to dc motor and its effect I would love to see it because I presume thats what this new power supply is all about.

One final word of warning the only people I have every heard referring to a stitch count are the Chinese because its kind of lost in translation but I found a lot of terms are different here in the US.

I think I might have to emigrate here, I am loving Texas so far.
