19-1-2009 UPDATED PICTURES (Beam photo's)
Today i finished my first laserprojector.
The goal for me was to use this project for practice basic electronics and working with alluminium etc.
The budget was SUB 500 dollars for the projector (not the DAC)
and i wanted a 3 analog laser setup in a "small" package.
If i would redesign the setup the projector could be 25% smaller.
I know its not the most smart/practical setup.. but hey i seemed the most logical.economical thing to do.
I keeps dust from falling on the dichros but make reallingment alot harder.
I think i am ready now for building a real projector with all the bells and wisles (safety and color).
It was a "educational" experience for me.
Thank you PL guys for all the nice information
special thanx to:
Jem (scanners for a budget price)
Stanwax/ROB (basic analog driver schematic)
DZ/dave (electronics) help
Xintrix (electronics)
Bill pangolin (electronics and schematics)
laserpowers (measured with synrad PW1 meter)
All safe levels for longer lifespan.
650nm 142mW
532nm 40mW
405nm 62mW (must get more power)
scanners: scanECO20's
videos extremely bad quality and shot quickly
note: 405nm wavelengt isn't recorded by my camera.
