radio shack sells 2 different ones. they have the 2pack that has the IR photoreceptor and the ir led and the led in that pack is 20ma i think.

the other is the high output IR at 100ma and thats what i am using on all my pens so far and it works great. just make sure you have the proper resistor to pump its max voltage. i always use 1.5 through my LEDs so when you plug your rig into the LED calc, tell it you want 1.5 forward voltage for each LED

Details, details. Things to do. Things to get done. Don't bother me with details, just tell me when they're done.

yeah.. I bought from radioshack the ones that come with the IR receiver and they're very very week. Prefer the ones from mouser.com. I used this calculator to calculate the resistor values: http://ledcalculator.net and they're working great :)
