If anyone is familiar with the video game console Wii, I'm having trouble trying building an infrared bar for the controller to work on my pc. For those who don't know, the IR bar works as a reference point by constantly emitting IR light.
Currently I'm getting a weak signal from the bar. I'm getting power through usb(5v I think), the leds are connected in parallel with 10 of them and tried 33 ohms, 47 ohms and 50 ohms.
I'm using these leds: http://www.goldmine-elec-products.com/prodinfo.asp?number=G13661&variation=
Can anyone tell me what resistor I should be using or if usb is not enough? I need it strong enough that I can see the light through a digital camera from a good distance(the same distance you'd sit from a TV)
