    "...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!

    The poly 20 is nice but they also have others here that should suit your needs. http://www.creativelaser.de/hardware/grating_page_frame/Poly-Gratings/Poly20sector/poly20sector.html There are some of the poly20 examples in the videos here;...

    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...

    The source code and the libs or environment that are linked to it would all need to be compiled in Linux.

    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 only run MS Windows 10 in a virtual machine and I hate in there too. This my first post here in 10 years and I am...

    Trying to clear an interlock fault during boot up on a t40-8ss power supply. The head is attached, and all interlocks have been closed and checked for shorts with a meter. The controller doesn’t show any data at any point during selfcheck sequence. Can the fault be cleared some other way? Maybe...

    I checked Edmundoptics.com and Thorlabs.com but none of the diffraction gratings they have are what I'm seeking. 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...
