How to Modify a Laser Light Pen
Laser light pens can be purchased legally from such diverse places as hobby shops and drugstores. The laser beam within inexpensive laser light pens has been deliberately adjusted to a weak setting, so as to compel you to buy a more expensive model. You can modify an inexpensive laser light pen by adjusting the screw that regulates its intensity. You will have to disassemble the laser light pen to modify it, but you will not need any experience with electronics, nor will you need to use a soldering iron.
