[Laser] San Diego laser communicator activity last weekend

Hi.

I have managed to strap an LED to the far end of my rifle sight. It only 
needs a small amount of current to be effective at night and Red seems to 
perform better than yellow / Green.

Positioning can be adjusted by holding the LED with an elastic band. An 
ultrabright LED running less than 1mA will give plenty of illumination and 
will last for many hours on a couple of AA cells or a 9V battery. The secret 
is to produce just enough light for the cross hairs while not reducing the 
visibility of the target area -which probably has a large spotlamp or laser 
pointing towards you anyway.

Congratulations on the 4 mile path.
