    Do they really have a product coming to market? From what I see on their website, they are trying to make this work since 2015, with little information about any progress... Would be great if they managed to pull it off!

    Way back when, we (at laserium) shared with each other things that worked and didn’t work - at all. (because - well - there was this thing called an audience - way back when...) Pretty much, we all came to believe that strobing the audience was a bad f...ing thing to do, if you think it’s just...

    I hate to feed the trolls and have yet another thread derailed by the "artist" formerly known as but... The tools don't make the artist. Any artist can use any tool. Some are dismal at it, others are amazing. I've seen sheet-metal art that dispels the hammer bit but it's hyperbole, I know. ...

    Okay, can I just say that ILDA was the F...ing worst thing that ever happened to laser shows? If all you have is a hammer, everything looks like a nail. I’ve seen two different “lumia” “shows” here in the last two weeks where the “choreographer” thought strobing the lumia was a good idea....

    Looks like a fun piece of gear. Just pledged my $. Any plans to make it 19" rack mount? The ILDA input sounds like a good idea too.

    kecked replied to a thread Combining beams in The Lounge
    The cube acts as the knife edge mirrors. Yes you set up the beams so they are knife edged prior to the cube but they are just aligned in a metal housing without the mirror. The mirror is the center of the PBS cube. and yes each stacked side is P or S and yes rotated with a waveplate. The result...

    No matter how you "stack" the input beams, you are still using the knife-edge mirror technique. You need the degrees of freedom to ensure the beams are parallel and as close as possible to one another. Adam

    kecked replied to a thread Combining beams in The Lounge
    Its pretty simple but easier to see if drawn. essentially you stack the beams into the cube, combine them and then dichro combine the result. Only advantage is less moving parts but much higher tolerance needed in machining to align beams to start. Once done though nothing should move. If you...

    buffo replied to a thread Combining beams in The Lounge
    Common suggestion, with an equally common caveat that makes it a non-starter. Here's the point that most everyone forgets: The output beam from a PBS cube is randomly-polarized (assuming H and V polarized beams at the inputs). So now if you feed that randomly-polarized output beam into...

    I don't personally own any 3d printers because I just mooch off of the ones at work *retardo . That being said: Stratasys Objet Eden 360V; formlabs; and a tazbot for quick FDM jobs. A few years ago, I built a beam table where almost all of the optomechanics and adapter plates were 3d printed. Gave...

    I think I need to see a diagram regarding how you'd align three colors with a standard broad-spectrum polarized beam splitter/combiner cube. I also can't visualize how'd you'd stack without mirrors. Buffo combined RGB with a RGB combining prism from a video projector several years back but...

    Will the finished model have ilda in? That would be awesome. To be able to take in an ilda signal and them mess with it in Radiator. I suppose you could do that with the audio in for X an Y but you would lose the ilda color modulation. That way you can do a mix of a canned show or frame and...

    A discussion was going on on LP about combining beams. It was the usual let’s serial several pbs cubes to make ridiculous energies. However it got me to think and here is what I thought. we use one cube to combine two beams. There is no reason you could not send multiple beams through the...

    Use black colored screen material. This is surprisingly amazing. Increases contract too as it attenuated all stray light.
