I need some electronics help (PIC's)

How fast do they need to deflate? Could always design it so they shrink down when pulling a vaccume. Then spring back when you let air back in

Pretty much what im saying with an air chamber in a closed loop with the baloons. Then actuator driven

I'm with you there. Now to start looking for components

PIC chip might be overkill.

Perhaps a 555 IC with an RC circuit and a FET or relay driving a solenoid could work. No programming.
