    That cleared things up a bit. Now we can see that we have the essentials of a full 6b scan glass system. Brian again, for preserving so many unique and important specimens of an otherwise lost medium. What is missing is the rolled steel pins, the steel rods, the knurled screws for the clamps, and...

    All valid points, Brian. My gear usually works, too. ;-) As the feller says, "There's more than one way to skin a cat." The rotating linear diff wasn't an issue within the planetarium dome, but was a very diff matter when queuing a net of beams over the heads of audiences with a 5 watt laser...

    Interesting collection of sfx hardware, Greg. I see a few concentric shafts (for multiple sfx glass), arms for sf mounting and levers, springs for returns... But, there are no solenoid actuators to make it run, like pistons rotating a crankshaft, with rods & linkages. Are you needing to mount a...

    Laserenthusiast started a thread DFB vs DBR (or vs VCSEL vs other semiconductor lasers) in Lasers, All Kinds.
    Hi everyone! I’ve been reading into semiconductor lasers and came across DFB and DBR lasers and while I understand, superficially, the difference between them, I fail to find an application or necessity that would absolutely need a DBR laser and couldn’t be done with a DFB laser or VCSEL...

    laserist replied to a thread CYGN-B in The Lounge
    Laser Images’ scan through actuator technique worked. The Hermit commented that its rotation into the beam path was a questionable feature, but that didn’t bother me. The scan glass comes up on a musical cue – the rotation is to the cue – the cue is over and so is the rotation – but the scan glass...

    Hi everyone, I've got a set of ScannerMax 506s I ordered from Pangolin back in 2015 before Pangolin's amplifier was available. Since then I had a no-so-good experience purchasing amplifiers from a member here, in the end he sent me four small amps after the original pair of amps he sent didn't...

    Here, due to the triple whammy of a show tape, video footage, and the secrets recounted by a performer, is rock around the clock fairly close, probably, to what was originally intended. How clever to use spiral sweep and rotations in this way. I agree that losing this content to the dust of time...

    I see how what I said may have sounded critical. Honestly, I was just poking fun at myself. That is, I have always wanted to "hijack" something but a "thread" is as extreme as a polite Canadian is likely to get. *I* would like the freedom to prattle, though I assume readers are more interested in...

    With grateful humility, may I say I agree. It is amazing progress to have soldered this ridiculous tangle of wires together and out plops Laserium into my lap.
