    Default Where you in 1978? Have a good laugh at Laserman532! Where were you?

    I was applications engineer at Spectra-Physics at 22 years old. Thats me on the left. (Afros were big back then). I had been working with lasers since 1975 and had a degree in lasers and electo optics at this point. I was honored to be working on scientific laser systems (pico second & ring dye) that would not become public for another 5 years. I played with laser light shows in my spare time. I still love the light.

    This was my first laser light show projector 3/4" 2'x3' plywood box with a solid 1" allum. plate for mechanics. (all hand made & drilled) Zoom in and note the aperature flaps with warning labels! This thing weighed a TON!
    Two 50 mw air cooled argon lasers, 3-10 mw hene lasers, two full color three motor effects, ledex rotary solenoids to switch beam positions and to 4 different "bumpy glass" effects wheels mounted on clock motors. All manual control with switches and knobs.

    There were galvos, but I couldnt afford them, no digital cameras, no diode lasers, (not even red pointers) limited internet & PC's were very expensive if you could get one. A AO modulator was just being developed.

    DAMN I FEEL OLD...Thank you for letting me share! I think what you guys are doing now is absolutely amazing.

    That's pretty cool. That's the kind of shows I remember seeing at the state fair in NC when I was a kid.

    I had to chuckle because i read a thread somewhere here in pl where someone was talking about motors with off axis mirrors mounted to them. Thats what prompted me to dig up these pictures. Even after 30 years that random generated spirograph patterns are still popular...something very...analog and time less about it. My actual first projector that I built in 1975 i have no pictures of are a 5mw hene hitting a mirror mounted to a speaker coil...everyone starts there even after 35 years.
