Now I want to build my own cap with 3 IR leds. I dont know anything about electricity and I dont understand much when people start to talk with ohm and Voltage. So I removed the IR filter from my webcam (Logitech Quickcam Chat) this evening. I have a cap. And this is what I have found so far. The IR led: http://shop.conrad.nl/componenten/opto-elektronica/infraroodtechniek/ir-componenten-osram/153831.html Something with resistance which I really dont understand: http://shop.conrad.nl/componenten/componenten-passief/weerstanden/koolfilmweerstanden/ and in another thread I found something here http://shop.conrad.nl/componenten/componenten-passief/weerstanden/koolfilmweerstanden/koolfilmweerstanden-0-1w/ the right battery holder? http://shop.conrad.nl/energie/batterijen-accu-accessoires/batterijhouders/651043.html And I am going to buy Wire Glue But how do I make an ON/OFF switch? Or where do I buy one? Someone knows where I can get the wires to wire it all up? Anything else I did wrong/missed? CAN YOU SEE/REAd THE LINKS? Did I do something wrong?

What I did was take apart a old dead transformer and used the casing and put my pcb board and resistor with a 9volt battery and the on/off switch coming off the top. if you need help or pictures just pm me.
