Instructions for an adapted laser pointer for low tech communication

I have put together step by step instructions on how to create a laser
pointer for low tech augmentative communication. It is available in pdf
format, and can be downloaded from: 

http://www.ucsf.edu/brain/als/resources/resources.html

The instructions are designed to be simple, so that a non-techie person can
put it together.
