On one hand I think it would be great to have the fascinating collection of modules I've been entrusted with by the Elders here available as a laser analog synthesizer for those who appreciate this art form. I'd love to make public my carefully drawn and verified wiring maps so those interested could appreciate the bread sticks beside the noodles.
Two considerations stand in the way though. Almost all of these circuits involve components that have to be found in limited quantities on ebay or the like. However, I do have most of the modules functional on breadboard, so substitutions would be easy to check.
The bigger issue is that I'm not sure I want to attempt to contact Jon regarding something which he and I have already spoken about. I don't have a go ahead to share the full details of the IP. I trust that you would keep anything private that I requested you to. I have a bunch of breadboard that I'd like to free up that currently has a full working CYGN-B on it, but I hardly want to ask you to work your magic just for that, and on top say you can't share it.
I think your RGB to RYGB color mod converter with a color mod I, color mod II, chopper, and a beam torquer would be a good for a project. After all the VCAs would need to be faster for today's scanners. So not a cut and paste of Laserium Stuff. And nothing there that couldn't be done with available components...
You've learned enough on this thread for a redesign of the CYGN B. I'm sure I've mentioned replacing the Johnson counters with dual buffered D/A converters with a micro controller to load the next value for each DAC.
Then there's KQO. It needs to be redesigned for today's scanners too. I'd do it as a feature of a spiral circuit. If you had ramp shapers for each axis of the spiral it could look like KQO when you want.
And a console has to have a joystick, and fixed rotations when there's more than one scan pair, and, and, and...
Laser Images patented this way back when. Patents expire. And I agree that some old components are unobtainable and others uncertain supply. That makes it time for a redesign. Like you did with the matched transistors in the spiral circuit.
If Ivan was still alive this thread and some others wouldn't exist yet. There's a difference between respecting Ivan and respecting his memory. Getting this stuff out there is respecting his memory. Ivan loved a review where the writer said Laserium may just become a major art form of the future. If that's ever going to happen we all have to let go, and show the world what was on our palette.
