i'm also working on a pick and place -- can i ask what your 're using for your head machanism? they look like some kind of solenoid that allows vacuum suction, but you seem to have a pretty clever mechanism to allow the heads to change.

Two of the valves switch on the vacuum, the other two generate a short pulse (15ms) to blow off the part. You can buy these valves completely integrated (venturi vacuum generator and two valves in one block).
For the nozzle changer I just glued a neodym magnet ring to the pickup nozzle. The SMD nozzles are clipped to a toolholder with simple fuse clips.
The rotation is done by a hollow shaft stepper motor. If you need more details I could post a close-up picture.
