IR Pens / 782-tsal6200 Power Source?
« on: May 07, 2008, 09:40:35 AM »
I have a quick question that I can't seem to find the answer on.

After trying out the Radioshack LED's I've decided that they are probably too weak for this activity, most of the light is on the top of the LED and it's not extremely bright to begin with, so now I'm going to make a new pen with the 782-tsal6200 LEDs.

Now I noticed they have a higher voltage, so I'll probably need a resistor and a new battery (I was using 1.5 N sized) so I want to know what my options are, and what are the risks of not using a resistor?
