    The Xcaliber projectors could be of interest. I have a PCAOM & turbotrack amp with scanners already but... I can't speak for others. Who knows what may pique someone's interest.

    Should I bring the rest of the ion projector parts? Fibers with optics, PCAOM, scanner heads + amps, Xcaliber projectors... stuff like that? I was thinking of bring all of those kinds of things. I am still torn with getting a small mixed gas (or an umbilical for the Omnichrome I have) since...

    btw: Anyone need or want a Teac 3340? I have one available w/user manual. Send PM if interested.

    Laserium typically used a Teac 3340 four channel open reel tape deck for playback prior to ADAT. The Teac's had unbalanced outputs, and so did the dBX units the audio channels ran through. The Mark 6 had 600 ohm line balancing transformers for audio (for audio mod) and data mounted on the back of...

    I have a ILT Argon that does about 8 lines at about 500mw total. Colors are great and makes a nice space heater for the garage in the winter. ;)

    Really, I have had DI water in systems for years and no growth unless it gets contaminated by something. Bacteria can't grow if there are nutrients available. But it is easy to get a system contaminated and then it's all over with. Like I said earlier, we use Optishield Plus on all of our water...

    That's a good explanation. Attached is a redraw of the 352 card first three op amps schematic. Was DATA RETURN important? I'm putting together an order which includes the capacitors I need to build this. Success so far regarding the 5 channel XY-RGB recording of the 6B rebuild output with the...

    diwater is very corrosive to all metals. It will try to suck as many cations out of the surface as it can. The inhibitors are buffers that prevent this. Diwater is also wonderful media for growing bacteria. The fungicide bactericide stops that. No way around it.

    Thank you for critical info.. This chiller is originally designed for trumpf multi kw CO2 lasers but i want to use it with rofin SC x30 (head & rf psu) 300w and trumpf trudisk 6kw. For sure has more cooling capacity than these lasers want but that's not a problem.. Are the copper & aluminum...

    Ok, I just cancelled my Florida Keys diving trip (they're stuffing 30 divers on a dive boat these days, and that does not sound like fun at all), but I can still do an airport run to BWI on Friday morning if anyone needs that. I can also do a PHL run if people have flights in the afternoon on my...

    I built a DIY A-102 drive amp based on GS's schematic in their GS-100 series open-loop galvos, shown here that uses back EMF feedback to improve step response: Unless you are just wanting an exact duplicate of their original A-102 drive amp, layout isn't that critical. My version is shown...

    A typical AOM uses a fixed drive frequency to produce effectively a diffraction grating. By amplitude modulating the drive signal the intensity of the light transiting the AOM can be controlled in a pretty linear fashion. In an image setter you want to have multiple frequencies individually...

    If i understand well this aom was used to form a deflected way of ray into the half-round cavity to cure the ctp-offset plates in the ctp machine. I think it will be a pretty hard task to make it work

    You are light years ahead of me. I just know the very simple basics. I would just look into an existing driver for a single channel and try that. I imagine running 10 channels will have some complexity to it however. Should it not function as a single channel AOM as well?

    Yeah, i know how they work ;) but the problem is what kind of signal, voltage, freq and so on. Fir the every aom need their own pulse forming network as a proper driver. Just sending a random rf signal will not work on my opinion.

    Yes, I do, and will post shortly. (Oops, sorry. I thought I did but only have their A-600 driver board.) If interested, here is my version of an open-loop drive amp that I used on the GS-115 galvos back in 1977-1979 using the single uA791 op-amp driver. This could easily be modified to be a...

    Typically you would feed a RF signal into each of the channels. That in turn drives a piezo element that is bonded to the surface of the crystal. The RF signal turns into a acoustic wave in the crystal and the crystal changes index of refraction depending on where the peak and trough of the wave...

    Yeah, absolutely agreed! I think its a true 10ch AOM, but mr. Steve still not share some info about how to deal with this kind of AOMs, as he told before :)
