Adding LED firing switch to DNA 250

Recommended Posts

what color is your LED?  I'm gonna guess blue???? you need a 100 ohm resistor. red, yellow or green - 75 ohm. got a radio shack near by (?) or just go on ebay and type in "100 ohm 1/10 watt resistor" depending on your soldering skills, maybe get through hole resistors rather than SMD ones. check to see if the switch you're buying already has a resistor inside, you may not need to buy one separately.

Easy until you try it and those tabs snap of if you breath in them.  Worst designed part of this board.  I would like to know if anyone has the schematic for a battery direct connection for the led since i now have no pads to solder to.  Also using white LED and a 4 pin button.
