The matching and tuning cap for the RF load on most of the RF excited aluminum tube lasers is (well used to be) under the fill port in the laser head, so to tune it properly you have to let the tube up to air. It is RF, and the load does need to be impedance matched. They should be close, but...

So after a bit of messing about swapping RF modules around, I managed to get about 8W out of the spare tube. I think, if I fixed the driver that has the blown MRF150 in it, it would be a bi better, as I don't think the earlier revision drivers do quite so well. Anyway, it's back on the machine...

Is a page found searching for high speed DAC of any relevance? Example: https://www.digikey.ca/en/product-highlight/l/linear-tech/high-speed-dacs

I think I see what you mean. For laser scanners, a ridiculously high sample rate has no value, but laser diodes are instantaneous so you can modulate colors into the RF range. Think of how an analog TV works- the scan rates are not all that high, but it takes several MHz of BW to get a sharp image.

Nuisances I’m talking about are purely hardware; the software works great and it’s clear that the hardware is operating at a full 192 kHz. It’s not a generic USB audio device, it has its own drivers, including ASIO drivers, and there’s not any difference between WASAPI Exclusive Mode and ASIO in...

Nope. What I was looking for was an app called Laseriods posted by Zoof on this forum back in 2008. Laseriods was written for use with the EasyLase laser DAC which is now obsolete, but you can swap out a dll file and fake it into running on a DC modified multi-ch soundcard. ...

Is this the one you were thinking about? I actually used some of Seb Lee-Delisle's thoughts about sorting objects to reduce the travel time between shapes in my oscilloscope rendering engine, but found out this was a bad idea in practice. I'll describe why: Let's say you draw four objects in...

Hey Allen! Thanks for sharing your info. I was amazed by the Oscilloscope Music site- the idea of hearing and seeing the XY is something I have always enjoyed and I incorporate it in my own apps. Most laser shows are choreographed around real music, but if you are generating abstracts with...

Hi Tommy, Generally I have seen the dichro's specificed as reflect X pass X so you will need to find one that reflects blue and passes red/green as you say (I might be wrong about this... someone for sure will correct me :) ) I found all of the ones I have currently in junk LCD projectors that...

Hi Dean, it's great to e-meet you and exciting to find someone else who is working with the same technology! Here's a bunch of info about my project(s): I took inspiration from Ocilloscope Music and old vector display arcade cabinets. The idea is to use modern computing and DACs to create smooth...

Ah, it´s out of one of these! Interesting tech! https://www.christiedigital.com/products/projectors/all-projectors/

1.4742 ist ferritic, but has a very high amount of chrome (17-19%), so the possible magnetic flux could be less than using ordinary cold rolled steel. Just use simple cold rolled steel (or for example 1.0715) for the stator and your scanner will be much faster.

Welcome to the Forum, Allen! I'm interested in learning more about your project, and I'm looking for a better DAC as well. I recently acquired a vintage Tektronix 100Mhz scope in mint condition and I'm sending laser graphics to it using a cheap DC modified 8ch USB audio adapter, but it's limited...

Greetings, all; Remember when I wrote that I won two ILDA awards at this year’s conference in Poland? Due to a mis-communication, it turns out I didn’t win two awards. I won three! A personal best. The additional award was for the Alien Black Box, visible here: ...

The whimsy is strong with this one...

Steve started a new job after an unfortunate incident defending a female foreign student from a known sexual predator on campus. She's fine, he fled the country. Steve is exhausted. And after nearly getting kicked off his other favorite forum for stressing laser safety... He's weary of BS> ...

Actually I just heard back from Pangolin that they may be able to to provide something custom, so fortunately there seem to be options.

Much lower price, .9mrad divergence, 40kpps, German made so the specs are likely legit. Wonder whose galvos they use.🤔 I also like their FX GOBO wheel, with rotating wheels & 4 position carousel. FX selection looks pretty slow and DMX controlled, which isn't a deal breaker. But, I'm wondering...

That's helpful! Thanks, Roj. I was also looking at the Laserworld DS-2000RGB.

I went looking to buy a fifth projector as a backup for a hopefully upcoming show. Unfortunately, I found that Pangolin no longer sells projectors that have ILDA interface capability. Suggestions for an alternative manufacturer for an aprox. 2 Watt RGB projector with analog color modulation and...

congrats !!!!!!!!!!!!!

Of course Steve knows that...Not sure if he is gonna help you set your house on fire. A lab bench power supply 0-60VDC 0-5V will help you determine why you got your hands on it so cheaply...

do you know how can I determine the power of each laser diode to built the power supply ?
