The simplest way to control that motor is to use a single D cell to run it and a heafty pot to control the speed. [wire wound?] Dropping 27 volts down to about .5 volts so the motor will run slow enough dissipates a lot of heat and will kill your nines off in a hurry for no reason and toast most potentiometers. Flat wide motors have more torque at the lower speeds. Grab one out of an old CD rom drive. You'll want to run it very slowly to prevent silver/hydrogen bubble deposit buildups [the dread grey fuzzies] and the formation of 'chunks and sparklies'.
The best way is to get a $$$ pulse width modulation device. Where? I dunno. Ode

CSers and Patriots, Can someone please give me specs for the little stirring device? I'm interested for the generator that uses three nine volt batteries, producing half a liter of CS at a time. My undertanding is that one type of stirring device consists of a top mounted motor with rotating plastic shaft and a paddle at the bottom. What I need to know is the specs for the motor, and would there be a resistor, and how many ohms? And I assume a potentiometer, or better yet something that fixes the rate of stirring. All the details would be much obliged. I feel sure this information has been posted here before, but up to now it's something I would have ignored.
