Main Question or Discussion Point

Hi everyone!
I am not sure if I am posting in right place, please correct me if needed.
I have an interesting project in my mind. And I need some help as I do not know how to implement it.
I need 400 suction cups and all of them have to be working independently.
Cups are supposed to be quite small (7-8mm in diameter). Kind of http://www.anver.com/images/components/f7-si.jpg".
Each cup has to lift a weight of ~15 grams (~0.5 ounces). It lifts like for 10 seconds and then releases.
They all have to be controlled by computer. And each of them has to be operated individually.
I was thinking of using 400 solenoids. But they appear to be not very cheap. Besides I do not know what other details are needed to be able to control them by computer.
Probably there is a better solution than solenoids. Maybe single big volume vacuum engine, and every suction cup controlled by valve.
I will be thankful for any information and help.
Regards,
Tony.

You could consider manifold solenoid valves. If you want to control each suction cup independently, you will need 400 valves. You would then need a PLC with 400 I/Os.

You could reduce your hardware if you group the suction cups. Could you run 10 per bank? This would reduce your valve and I/O count to 40.
