    I think you'll find the product line is new enough to not be "out there" enough for reviews. Steve

    I had a christie with mechanical shutter that would sometimes not open all the way. EDIT: opps didn't see your last post. I'm 99% sure the Panasonic doesn't have a mechanical shutter.

    I don't run them both at the same time. I guess I should have provided more of a back story. Our Panasonic D4000u, mounted on a lift in the ballroom, crapped out last fall. Basically there is probably a polyswitch or something causing it to shut down as soon as the splash screen comes up. I...

    Eidetic replied to a thread hand drawn hologram in Hologeekery
    People use e-beams to write surface relief fringes (scratches) into substrates to make masters for embossed hologram production. The resolution and complexity of the image comes with smaller and smaller fringes. Same thing with digital holography on LCoS. We're using 3 micron pixels and they're the...

    I guess no one has experience with these? Must be a new product line. Someone reached out to me thinking I was talking about Kvant ClubMax lasers available on Pangolin's site. I'm looking at the ones available at https://www.clublasers.com/ . Apparently they're Pangolin's own line of projectors.

    I like where your head's at! That would be really cool. It would be fairly precise too. Curious how small a spot the laser would have to be. I imagine pretty damn small.

    Now I like that. Wonder if you could do this with a laser cutter to make slight grooves. Much more complex possibilities. Write some code to take an image and convert to the scratches.

    May I suggests a bastad cheat.....pair of polarized filter gel to match them. Make the brighter dimmer. Maybe start in the eco mode for the bright one then a pair of polarizers to adjust it just right. It will work but you give something to get it.

    Thanks for the reply I am not educated on the history of holograms. It looked interesting so I thought I'd add a post to a quiet forum section.

    Bradfo69 replied to a thread DLP Projector question in The Lounge
    I'll check the eco mode. (Not patronizing) It actually has two bulbs and I think is running in dual mode. If it's something more severe than that like a potential burned DLP chip, then that's beyond my scope. It's also mounted 14 feet in the air in the ballroom so, not a whole lot I can do...

    Eidetic replied to a thread hand drawn hologram in Hologeekery
    The very first 3D holographic image was made by hand drawing the fringes to be expected from a simple image (three crossed wires). Transparencies of the drawings were viewed in a stereoscope as in-line Gabor type holograms. A paper about the technique is below. This was done before Leith &...

    or misalignment, or dirt(soot) burned dlp chip. ECO mode sounds like a good place to start. Then see if you can measure the output of the bulb in place in both projectors before the optics. The power supply might be weak too. Missing reflector?

    http://amasci.com/amateur/holo1.html Not sure this really qualifies as a hologram as it is not a diffraction pattern. "a three-dimensional image formed by the interference of light beams from a laser or other coherent light source." http://amasci.com/amateur/hand1.html verdict?

    I don't want to sound patronizing but you're sure one of them is not in "eco" mode?

    Two identical higher end ($7,000) DLP projectors. One appears dimmer than the other. Take the bulbs out of the bright one and put them in the dim one. Changed the actual lens too. Still dim. Ideas on what to check? It's not tremendously dimmer but, maybe 30%.

    yes there are freely available programs that allow you to test out IDN without having the hardware, such as an IDN viewer etc. Dirk posted some links on another IDN post on here, to Github, with the software and sourcecode etc. The university of Bonn have also released some tools to help. It...

    Ah yes, good idea, I've had that on the backburner for a while. Biggest problem was that I didn't have hardware to test it on, and the DexLogic units are a bit expensive for a budget hobby developer like me. Is there a program for loaning them for development purposes, or a software emulator, or...

    The glasses are PHMDs (projective head mounted display) also known as HMPDs (head-mounted projective display). These have existed since the 80s, but shrinking of reflective microdisplays into the sub-inch sizes and development of high power monochrome LEDs suitable for pico video projection has...

    I have the manuals and the software from RMI. It's the connection from marking head to PC that I need. Like I said, i dont have the DAQ card and cables that RMI originally provided with the system for the control interface.

    Can you show what's on the other side of that 37 way connector? If it's one of the common marking interface cards, you may be able to drive it with free software without too much additional hardware.

    I am currently looking at 3w RGB systems from Goldenstar, Lightspace, and Able. I called Pangolin to ask about how to control FB4 from the Virtual DJ plugin they have available and was made aware of their own Club Lasers line. I was told they would outperform what Lightspace offers, particularly...

    I hate that they use the term "gain" to describe how bright a screen is. They should be talking about reflectivity. Grrrr. To further complicate things, the "gain" that most screen manufacturers quote is actually a comparison to a standard coating, like titanium dioxide, and not a measurement...
