[Laser] Sky illumination experiment

[F1AVYopto at aol.com]

Hi  all 
May be  a simplest system could be used. 
Why not  a simple mechanical rotating shutter associates with a powerful 
halogen  lamp? 
A  synchronic motor powered by a simple audio amplifier with an up 
transformer  should be adapted. 
One can  find 240 V small synchronic motor in all the low cost AC automatic  
timers. 
A PC  with LASERSCATTER or JASON in the 70 to 90 Hz range should drive the  
motor.
