Well, i finished my build.
It's a 3 IR-LEDs of 60º (in my country it's more difficult to get the 485p's IR-LEDs...). The leds are 2.1 v and 100 ma front. 2xAA batteries, and 6 resistors (in parallel, a pair for each led) of 15 ohms each. (That gives me 7.5 ohms for each LED).
My doubt's are this:
The switch must be in serial in the positive cable that comes out from the battery holder? (i didn't know that i had to buy the Battery carrier WITH a Switch). My setup didn't work until i took off the switch...
Second and most important:
The illumination that i'm getting from one of my LEDs (in daylight, with some shadow coming from my hand) is this:


Is that enough illumination?
