Gears

One of the things we've learned is that we need to reduce the rpm of the lumia down to .5 in order for it to feel slow enough. We'll be doing this 2 ways, by regulating the voltage to slow down the motor (without losing adequate torque) and then by using gears to further slow down to our end goal.

The picture below shows the motor on the right and our first prototype of gearing which results in .5 rpm. Dave has since acquired some really nice metal gears off ebay, and he's hoping to be able to make adjustments to be able to use the new gears.
