   Laser diode module and audio amplifier tia sal2   
      
   Greetings All   
      
   I have a laser diode module with the datasheet of   
   output <5mw   
   wavelength 640-660nm   
   that is powered by 3Vdc I've created a simple laser communicator   
   following the instructions from   
   this site http://sci-toys.com/scitoys/scitoys/light/light.html   
      
      
   This works great but I was wondering if I   
   could power my laser module using just the output of a cheap audio   
   amplifier (like from radio shack) and not use the transformer   
   if so what calculations and changes to the circuit   
   would I need to make to prevent destroying the laser.
