My intentions with this Instructable are more along the idea of giving other people a project idea, not so much laying out how exactly to do it, so bear with me, please =D
All credit goes to britknight for the idea (http://www.instructables.com/id/Wiichuck-Controlled-Turret/#step1).
I saw yours, was inspired, and thought I'd share what I did!
NOTE: I didn't have much time to put this Instructable together, and I won't have access to a computer until July 2015, so if you post questions, just know I won't be able to answer. =)
