I built the control box I agreed to build today. My dad helped but I did most of it. I changed the design from a box to two switches the operator holds in his hands. I think it will be a lot easier to operate this way. I wasn't able to integrate a variable resistor into it because the one from Brian goes from 0 to 100 KOhms and the range we need is about 0-24 Ohms. This is because the motor will be about 1 Amp at 12 Volts. The big resistor worked but it didn't have the fine control we need.

Jamie:

just called Eric and the worm gear problem has made it nearly impossible to come down when at the top. I am wondering if we're actually going to make it to the challenge.
