Can Throwing Fridge - Part 1

I finally started my project to build a soda-can-throwing-mini-fridge.  I've talked about it for a year or so, but now, I have actually ordered parts AND stated assembling. While I do not have the actual mini-fridge yet, there is much I can do without it. For instance: assembling the electronics, computing multiple throwing distances/angles and the necessary springs and motors necessary to make them. (Continued...)

The first part I have made is a ciruit that will control the 2-3 motors I'll be using: 1 to life the can to the top of the fridge, one to cock the catapult arm, and one to rotate the catapult base.  There is a picture of it below.
