This is the obligatory "Why not spend 5 extra dollars and just buy one" response. I mean, seriously, you'll wind up saving yourself maybe 5-10 bucks by the time you buy all this stuff, plus you gotta put it together yourself. I might as well also mention that your hopper won't spin as fast as it would with regular batteries (Yes, yes, yes, I know, I know, I know, it spins with each shot, supposedly providing a more consistent ball flow, but it still spins slower since it's running off a 6v battery), and that you'll drain the Angel 6 volt battery much more quickly with the hopper powered. An Egg II or HALO B would be much more effective if you're looking for speed and/or steady ball flow. I am interested in finding out where you can get the board connectors though, that would come in handy for a variety of things.
