<DIV><FONT face=Arial size=2>Hi.</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm a fan of the old optigan organs, and after
despairing of finding one in Wales, have decided to have a go at building one.
The principle looks straight forward, and I can code a little, so I think I can
make something similar using a computer to generate the tracks.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Rather than attempting to make circular records, I
think it will be possible to print the waveforms onto transparent acetate with a
laser printer, and roll the resulting sheet around a clear plastic tube about 6"
in diameter.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I will then put the light source inside the tube,
use a motor to turn it, and use a single hand held photocell to select the
tracks.</FONT></DIV>
<DIV><FONT face=Arial size=2>With a 1400 dpi printer I reackon I could get about
2 seconds of 7k bandwidth with a pretty low amplitude resolution with about 10
tracks per sheet.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Anyone tried laser printing waveforms onto acetate?
I'm not expecting hi-fi results. :)</FONT></DIV>
<DIV><FONT face=Arial size=2>I guess the only way is to try it, but I would be
interested to see if anyone else has had a go, and if they had any
advice.</FONT></DIV>
<DIV><FONT face=Arial size=2>This list looks like a good place to
ask!</FONT></DIV>
