    If still available I'll take everything minus the galvo and amps if possible. Let me know how much you were thinking and I can probably send over a payment today.

    So I am located in Key West Florida. My interest revolve around the design aspects of shows. Most recently I have found myself lost in the concept of coordinating live show design using SMPTE.

    Hi all. I stumbled onto this forum and wanted to take a moment to introduce myself. I am very new to the laser game but have been certainly been enjoying the journey!

    Would a 60W MOPA work like the video I posted, or, does that look more powerful?

    I'll send the BurrBrown chip with my next shipment of Laserium artifacts. It just occured to me that it might be a cool effect if you used the ramp shaper on just one axis. It might be similar to the KQO symmetry effect.

    laserist replied to a thread CYGN-A in The Lounge
    The dual transistor in the spiral ramp circuit is similar to the 2QMM circuit. I'm guessing, but I believe it was to get a log frequency response from the 0-10 volt up down ramp control voltages. You see it in audio synthesizer circuits where they're after one octave per volt VCOs.

    An error causing the low amplitude of the CYGN-A oscillator was found. Photo shows the three oscillators. Other photo shows the collection of the less common semiconductors which should be able to become the SPGN, except for the Burr Brown, with which this build will have to do without. If I may...

    I used these. https://www.rfparts.com/r161075040.html You will need a crimper to use these connections. There are crimpless types of connectors too, just more expensive.

    Hello, I made a bash script, that, when executed, selects the next preset from a list, and drives the radiator via MIDI. On every invocation of the script, by command line, a cron, launchd or atd system, or even the return code of another script, it will launch the next preset. The list is in a...

    In menu K, you will see that there are vertex cursors. One looks like a square and the other looks like an 8 way cross. I call them the egg and the spider. You can move them around the vertices using the } keys. You'll notice you cannot move past either end of the vector set and you cannot move the...

    Ok, so using the NanoVNA I put a connector on one end of the cable and started cutting pieces of cable off till I got to what appeared to be a perfect open at 100MHZ on the smith chart. Cut a touch more off to compensate for the center pin and crimped it all up. And it works. Finally. This is using...

    The spiral card had 3, 0 to 10 volt inputs from the 351 data, and two digital inputs. Out rate, in rate and sweep were the analog signals, spiral reset and diamond spirals were the digital inputs. So you could control how fast the ramp generator ramped up and down, reset the ramp, and the sweep was...

    And thus, a slice of history is revealed in a log book entry. The photo shows this circuit built using a KIA324P quad op amp. The output is a beautifully tunable quadrature. But the output amplitude is only slightly over +-1V. Is this correct? I notice the 10K in the summing amps suggests some gain...

    Since I have been building lasers I always thought that diode mounts missed something. Some one can be fixed from below, some allow the diode to rotate to find the sweet spot when using prisms or cylindricals, .... So I thought to try and design a mount that overcomes some of those disadvantages....
