    Excellent point, Gary. I agree that the FB3 probably does not have much of a buffer, to say nothing of the firmware to sync to adjacent controllers at a per-point level of accuracy. Adam

    Found this one this morning... A lot of four used Star Tech USB-over-Ethernet extenders, each with 4 USB ports, for a total of $130. https://www.ebay.com/itm/274124452287 Unfortunately it's just the receiver ends - no sending units. (Got an e-mail back from the seller confirming this). ...

    External sync is just a way to set the clock time. Once set, sending data accurately is easy. But, that means being able to store the data until the precise time to send it. If the FB3 doesn't have the buffer space and the firmware for it isn't written in a way to take advantage of such a thing...

    That's an awesome build! 405nm is kind of disappointing in my opinion, except for glow-in-the-dark. Human M and L cone cells have a long tail in their response curves out towards 400nm, plus the S cone response is low to begin with in that part of the spectrum, so on its own 405 looks a bit...

    I wasn't planning on putting the 405nm in a projector. I'm just curious how it looks in person. - Building a little module around a low powered 405nm diode would also definitely make for a fun evening. The 506s definitely look great - I'm sure they're well worth their money - but they still cost...

    I do a lot of custom building with a focus on compact builds and high performing graphics. The Compact-506s with MachDSP amps and their 3.2A per channel PSU have the smallest footprint you can get for 40Kpps graphics. The 506's cost much more than what you put in there, but the ability to scan...

    If you're trying to emulate a 555 timer in code... As it was explained to me (by Carl Hannigan long ago) when two 555 are close to firing at the same time the first timer to transition will trigger the second timer to fire early.

    462nm is damn beautiful. Can,t wait to build the first 12 combiner in a 462nm/445nm combo. That with a 12x 520nm and a 12x638nm/700mw will be crazy *retardo

    skip the 405nm unless you plan to do glow in the dark. better to go 460/445 or something like that. below 445 is not useful. it upshifts to 460 or so anyways. get that 660 in there it matters. stay as far above 520 as you can 543 isn't common but its beautiful. a good dpss 532 will make...

    Thanks for the kind words, guys! Sounds beautiful! How would you implement the control logic for mixing all the different colors? Would this be handled by software? I also really like the deep red 660nm provides. I must admit I haven't seen 405nm in person yet, definitely have to get a few...

    laserist replied to a thread CYGN-B in The Lounge
    I looked at the wire lists and the center osc's AM and FM signals are the top osc's sine output. The bottom osc's AM and FM signals are from the center osc's tsin. The top osc's AM is from bottom osc bipolar squarewave, and its FM is the bottom osc's unipolar squarewave. Sorry for the confusion.

    Actually, your comment that a frequency could be driven to zero by fm may be part of the answer. I think I remember doing that. You'd have a dot that would sit there, and then whip around once. But you would adjust a frequency and synch it to the music, and that was a lick.

    Just for the record, a digital multi-meter is not going to give you an accurate reading of the voltage on the X and Y output pins of the Quickshow controller because those signals are constantly changing in time. (It's an analog signal with a varying time period that changes based on your...

    The Quickshow controller doesn't have any support for external sync, but the FB4 does. I've seen FB4s running off time-code, for example. So, yeah, I'm sure that Beyond is somehow syncing all the FB4s to each other. No idea what the exact method is though. I suspect that they could also...

    It's sometimes difficult to find the exact factory replacement parts for foggers and hazers, but I've had good luck with 3rd party suppliers in the past.

    I'm beginning to doubt my memory. I'll have to dig though the wire lists to check my memory of how it worked. If you look at the console and number the channels 1 to 3 bottom to top, the #1 AM/FM signal was definitely bipolar - in fact it would drive the frequency to zero at full gain and low base...

    I know this question is somewhat old, but may be this helps a bit. SL2-100 is a serial protocol, it no longer makes use of separate lines for X, Y, clock, and sync. This image is from the official manual: So the position data for X and Y (and perhaps Z) need to be transferred...

    Well, there are protocols that achieve high precision timing over network links, for example Precision Time Protocol (IEEE 1588). This is used in AVB, to achieve sub-microsecond sample alignment between channels, which matters for audio since human hearing is very sensitive to phasing. However...

    Yes, the duty cycles of the square waves in the emulator are at 50%. This leads into something I'm finding a bit puzzling: Using square waves as modulation signals doesn't seem to produce anything I remember seeing in the shows. Any recollection how a square wave, particularly as an fm signal,...

    How is that? With ethernet you have no guarantee of delivery time. With USB you more or less do.
