Hi ho,
All this talk about hacking has made me interested in getting one of my pet
toys back on the bench to gain ascention to a new level of uselessness.
Background:
About a year ago I bought a trashed Pioneer LDV-1000 LaserDisc (the 35-Lb
monster in the Black case) player, and tore it apart to get at the HeNe tube,
and the scanning head. In a few hours I had chopped out the power supply,
defeated the interlock and had the tube running great. The next step was to
wire up the x-y scanning surface mirrors to a couple of simple audio amps
(LM386's for those in the know) and wired this unholy creation to my CD players
headphone output.
Wow! Read instant Laser Show! Ok, big deal a diagonal red line with fuzz
around it where the two halves of the stereo image differ. My next addtion
was a crate for the beast and borrowing the digital delay pedal,( and later
the flange pedal) from my guitar, I was able to turn out a slightly more
interesting light show.
Read squiggly figure eights, gyrating elipsoids, and more fuzz.
Now I would like to expand on this beast. Here are a few options I had
in mind, but if anyone could suggest more interesting possibilites, I would
like to hear them. If anyone else out there has been eyeing one of these
relics, and would like to know how to turn it into a toy, I can provide
the needed info to pull it off:
1: more analog circuts: filters, my analog is weak, but I can build filters, and
amps from diagrams...
2: simple cpu, digital-analog, etc...
3: A-D to CPU to DA for a more elaborate abstract music box...
4: leave it as is...
