Our code shuts down the vacuum as our kicker is firing, and then starts it up again once we load the kicker (the kicker foot blocks the vacuum after firing). We even have feedback on if a ball is loaded by monitoring the draw of the motor. The vacuum works amazingly well, considering how simple it is: It's just a mini shop vac impeller on a fisher price attached with a short tube to a tupperware bowl.

Our kicker is powered by four 25 pound steel tension springs. It's on a ratchet assembly, and we use the same motor to load the kicker and release the pawl (CIM on a p80 gearbox). Also, to get a long range we found the shape of the kicker foot is *very* important.
