    Hi Chris, As you know, I've been interested in your work for over a year, which has inspired me to get back into lasers. Thank you for that. In fact, I've been following in your foot steps and now I'm building my own control desk, just as you have with the Radiator. Different strokes for different...

    Hey Ron! Thanks for invoking me ;) Pretty much every control on the Radiator can be operated via external midi commands. This includes toggling presets. One of the things I've been doing lately is sequencing Radiator shows by using LSX timelines to send midi data to Radiators. Here are a...

    Well. Du~uH. I should have read the caption above the photo. Since I don't have a facebook account, half of the page was blocked by a sign-up popup nd I was focused upon the photo. So, Ivan and these laserists are actually pictured 20 years older than when I knew them. Now, I recognize Scott and...

    Unless I'm mistaken Scott Anderson is the guy behind that account. In the photo from the 25th anniversary he's the guy seated to the Right of Glenn Thomas.

    Of course, the tall gentleman on the left is Ivan, but much older than I remember. The Laser Rock reference makes me assume that the photo must be at the launch of the show, which would have been late 1970's. We started running LaserRock in London ~1979, but Ivan looked ten years younger then....

    Actually, the Aries only had 2 rows of preset buttons in 4 banks, plus UDLR control buttons and the 4 output assignment buttons. But without knobs, it was far from perfect. Was that English desk a flat panel, about 2 ft square? That probably would have been the Laser Systems' desk, from Wales....

    I don't know who this is, but this Facebook page has loads of rare Laserium photos and knowledgeable comments: https://www.facebook.com/pg/LaserockLaserConcerts/posts/ Perhaps the individual involved would be interested in what we do in this thread.

    One of the best live show laser desks that I've ever used, back in the days of live laser shows, was the Aries, by Laserpoint, UK. It was a 3 scan head, full color Krypton/Argon projector, with a desk of preset images and sequences that could be routed out to any of the scanners by pressing the...

    Steve, I completely agree. If I had to control the entire Laserium show manually, I would have melted down into a shallow puddle by the time the show was over. The basic choreography produced in our studios was essential. As laserists, we could always override what was sent us, but rarely did....

    Yessiree ;-). Interesting about the lumia patent. I just cannot bring myself to imagine how on earth that patent could even be defended from the "front or back", to wit, sunlight bouncing on rippling water or snowflakes = well known.

    "...in a well known fashion" or "Such recording techniques are well known" is legalese for "this part ain't patentable, ain't part of our patent application, tis in the domain of common knowledge". Thanks for posting the patent, Steve!

    I would not try to do a modern planetarium show without a data track. Z-5 with the color box is awesome, but you'd need something to record and edit on. Radiator requires immense practice and memorization to be effective outside of a Rave. . To really do something with it I'd be using the"Save...

    I believe "well known fashion" refers to "voltage controlled"... Perhaps the lawyer was paid by the word. Actually Ivan once told me that when their original lawyer died the new lawyer said he hoped they never had to defend this patent because he had no idea how to do it. Another interesting bit of...

    In section 7 (p.11) of the patent Steve posted, is stated: "A voltage controlled spiral generator 146 may be controlled, in a well known fashion, from the output of the data acquisition system 140..." I wonder what was meant by "in a well known fashion". Was that something the teenagers were...

    Appreciate the info, I am surprised this company has such an old tech looking web site which is difficult to find examples of what each pattern is, but that is what I am seeking, diffraction gratings in glass and not plastic. Thanks!

    Yes, that was our London Laserium projector in 1978. Great to see those mechanical drawings, as well as the modular electronics drawings of the waveform generators, mixers, & multipliers. See if you can spot the similarities with my current Teensy modular connections on my latest controller...

    Glad to still be here, all things considered. TBH, I didn't really understand the question from the get-go. RYGB gains? So, instead of solenoid beam shutoff flags, each scanning head had it's own intensity scanner? R= 0 phase, Y=90 phase, G= inverted 0/180 phase, B= 270 phase for colormod, perhaps?...

    Glad you're still here, TheHermit. Yeah, no, nothing to do with the colormod. That subject will come back up when the expansion of Brian's colormod signal to RGB circuit to include 4 RGB channels with fixed color offsets and beam torquer is imminent. I'm talking here specifically about the RYGB...

    Has anybody got LaserShowGen to run on Linux? It seems to be an exicutable, which is not a linux thing. Would consider another show maker if it worked with Helios AND was on Linux.

I'm looking for transmission gratings (as opposed to reflecting) which produce different patterns. The one pattern I am most interested in is a circle, I can find them on ebay cheap, but...
