Great job on making the interuptor. I needed one for a bubble machine he got for Christmas. Cheers! john.
The plastic tripod that comes with it doesn't really hold it in position well. I have much better luck mounting it to a table or wheelchair with a "Manfrotto Magic Arm" (aka Universal Mount) with a clamp on each end.
There is more info on setting up and mounting these on my "Combat Wheelchair" project page here: http://www.gavinphilips.com/projects/combatwheelchair-1
The battery interrupt should work to fire. Maybe a couple of servos to aim. One for up\down, the other for left\right, wired to your chair's joysitck or an Arcade joystick.
