    Thank you for the educational PDF. Always wondered how that effect was SOOOOOO stable. Steve

    Seems cruel talking about the schematic and how it works without looking at it in front of you. So... for your edification, I present you with that schematic (I had to break up the PDF in 2 parts of less than 5MB each for the forum software...) Included is some pretty good documentation. Ron

    The Danube loops and eights were generated by clock/divider circuits. (2 pairs of divide by 16 and then divide by 2048/4096 counters. One had a pulse synchronizer that could insert a 0 to 20 KHz clock in one pair.) Those circuits sent square wave pulse trains through integrators to convert to...

    I wonder if anything further is known regarding that modification, as that sounds like a very useful modification. So that's a cat's meow. The project includes the original slotted can chopper. I certainly noticed the change from this to the aom. It was like an insanely fast chopper, but with no...

    The Danube board generated a slightly variable 100 Hz sine wave that was controlled by a 0-10V input voltage. It generated fixed 100 and 50 Hz sine waves. The combination of the fixed and variable wave forms generated Lissajous loops and "eights". When the 0-10V signal approached 10v the variable...

    One of the great Laserium choreography numbers was to the "Blue Danube" and consisted of slow, graceful variations of the classic rotating, RYGB, Lissajous figures and cycloids of slightly out-of phase 1:1 sine/cosine signals, coupled with quadrature DC RYGB movements, moving to the music. I'm...

    For the record the slotted can chopper was used on the Mark VI until the Beatles show mods.

    I pulled apart the module and it seems to be a diode lens issue not being centered on the diode with a short FL. It causes that smear coming off the diode itself before correction lens. I decide these are pretty much beam boxes and even on graphics after about 30 feet you do not see it, so for...

    Greg, that cylindrical can with the slots was the chopper mechanism from the original Mark 4 projector before the advent of AOM's or PCAOM's. We chopped the beam, which went through the two slots, mechanically. That cup was mounted on a big-ass, but slow, scanner. The one nice aspect of this type...

    The steel rod and the three pieces of brass tubing are for a scan glass mechanism. There are a number of old and new style scan glass mounts in the mess I sent. For the joystick: You need a one inch disk with a 1/4 inch hole in the center that also has a hole drilled and tapped radially to...

    I have never seen a slotted can galvo, but the thing in the photo is what I imagine one would look like. Or is that the round aluminum disk about an inch in diameter with a 1/4 inch hole on axis that is part of the joystick? Shown in the photo is as much as I can get of the joystick together. I...
