	   The following plans are for a light laser.This laser can be used for
many things,mainly for security systems.All parts are fairly easy to obtain...
if you can't find a part then you can order it from the following address:

		      Information Unlimited Inc.
		      P.O. Box 716
		      Amherst NH 03031
		      -or- (603)673-4730

If you want a different colored laser then order the following parts:

  Hewlett Packard #HLMP3750 for red, #HLMP3850 for yellow, #3950 for green,and
  XCITON XC880-A for infrared.Before I give you the schematics I'll tell you
I'm planning on making another g-file on how to make a laser detector to finish
off a security system.I don't know when I will get aroud to doing it though.

    Way to place in tubing:


	  circuit board
	 / _________________	   pot/switch combo
	| |		    |  __ /  (to set power)
       /|-| battery pack    |_|  |_|\
       \| |		    | |__| |/
	| |_________________|

	You overlap the two tubes so you can move them back and forth to set
       the lense to hit your target right.
