I'm having trouble figuring out how to wire my saber without risking blowing out an led. does anyone have a schematic to show how to wire a 4 x AA battery pack with an a/v switch, 700 ma Buckpuck and a red seoul p4? I dont want to use trial and error and accidentally blow out the led in my a/v switch. Thanks all!

The key to this is making sure you have the correct resistor for your a/v switch led. The forward voltage of the switch led is mentioned on the store page. To know what resistor to use you can calculate it here (http://led.linear1.org/1led.wiz)
You'll enter in your battery pack voltage (source), the forward voltage of the led as mentioned on the store page, and the forward current, also on the store page. Then it will tell you what wattage/ohm resistor to use.

I've been working on the same thing for my saber this morning/afternoon. Just ordered some resistors a few minutes ago.
