Help Needed Guys
Hi guys. I really need some ideas on how to shield an IR detector board. The one I got from Nick is just the boared with the red LED's and the IR sensors. I need too make it portable also which makes things a litlle more complicated. If I wanted too bury it in the 88mm diarama it wouldn't be so hard but I have made a contol box for it so I can just pick up the gun and box and be off with it as too not have too take the whole monster diarama. Any Ideas? Thanks guys.

You can shield the IR dectector with any Non-transparent/Non-translucent medium, like cardboard or plasti-card.
Hiding the dectector would block sensing hits, not fair. If you hide it behind a semi-transparent medium (like a dark colored celulose sheet), you would still score hits.
You should not need to shield the circuit board, just hide it. Try making up a stack of ammo boxes (Made from balsa wood).
Hope i understood your question and provided a useful answer.

Semi-transparent medium can't be glass. IR doesn't pass through glass well. The glass attenuates the signal a lot.
Of course, that said, glass would probably be heavy and hard to work with anyways, huh?

Maybe you mean http://darkith.dyndns.org/~darkith/html/dbu_inst.shtml Goldenraven?
Panther G, what do you mean "shield" it. Do you mean shield it from IR shots from tanks (to make it harder to hit), or do you mean shield it from sunlight to stop false hits?
If it's sunlight, you could do as GoldenRaven suggest and build a baffle set for it. You could also try a piece of dark exposed film negative (if you can find any!). "A simple visible light filter can be made by cutting the dark portion off a developed 35mm film negative. This will absorb most of the visible light while passing the infrared signal through."
Even better is to do both...
Other solutions would be to scavenge a visible light filter from a TBU, HBU, or old remote control that has a dark "window" over the IR LED.

Yes darkith it was the light filtering I was concerned about, not hidding the IR detectors from hits. that woulnd't be sporty now would it LOL.
