Help with prop/device

[mjschmu]

Well, here's the idea:
This would be used in a scenario where you have to shoot the prop (essentially a small target) say, 50 times. The winning team would be the team to "activate" the enemy's target. the only thing is, I need a way to trigger a relay after the 50 bb's have entered the target. My solution now is to use a photoresistor and an LED at the top of a tube. when the 50th bb (or however many) gets to the top, it breaks the light connection between the LED and the photoresistor, triggering the relay to do whatever you want.
here is a simple diagram of what i'm talking about:

If you have any input, it would be greatly appreciated

Yeah what about using a metal plate that would be shot 50 times or however many times and it would get pushed back until it hits another metal plate that is exlactrified and it would lite up a bulb or somthing.
ill have a diagram of it later...

thats a good idea, but my only concern with it is that it wouldn't be 100% reliable. For example, people might shoot from different distances, with different guns, so the amount of force that would be hitting the plate each time would be different.

Most interesting mjschmu. Have you consider a switch based on weight or on both weight and count? Mjschmu, you design seems to be designed for a minimum of say 50 bbs to trigger your switch, but nothing to stop people from shooting more than 50 into the collector.

I suggest you make the target out of something cheap/easy and ESPECIALLY fragile. (I think I know what you want this effect for) If the opponents are shooting too hot or get too close with hot/high speed guns, then they would damage the device thus failing the objective of getting x amount of bbs in there and setting off the device. This limits the type and range of weapons that can shoot at the target.

Food for thought.
