semi auto triggering system

[churrito_y2k]

I would like some ideas on the triggering system of materials and functions for self built "paintball gun" posted in http://www.spudfiles.com/forums/viewtopic.php?t=160&

what i need to do is use the basic system, to shoot a pin-pon ball across 6 to 8 meters to another identical machine, which catches it (i was thinking in using a net!), loads it, and shoots the ball back to the first one, as long as the machine keeps up this cycle the better the grade for my class. but once one machine is started there can't be any human intervention to activate the machine! i was thinking in using photo-sensors to trigger the machine with a motorwhen the pin-pon ball enters the loading chamber! what do you think? any other ideas? if you have any idea of how to make a compressed air system like in the link it would be much appreciated!
