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 ?

I use a 3DLP xenon projector, I remove the lamp and power supply, digital porjection 30sx model; I use set xy scanner to scan inside the light integrator to get a full distribution of light in the screen , fiber optic works too

Wait, you did what?! Did you use a 6W laser as light source for a DLP video projector? And it held up for that kind of power? Super cool, I want to try it!

Yeah, I got this 48-2 with the dead RF drive the same way, I kept it thinking when the tube in this eventually gives out, I always have the other one to swap the bits into. I don't remember if I ever tested it before hiding it on a shelf. The machine (an ancient Universal Laser I picked up on...

I can test it when I find the PSU that came with it! I have a few 48-1's too in the same box, I sniped them for 100USD on eBay back in the days, pulls from medical equipment it seems since they have the auto power sensor accessory.

Just as a quick question, does yours produce roughly half power with one drive stage running? With one of the drive stages blown it *should* produce some output afaik, if the gas is good. The one I have with a blown stage was supposed to be a good tube too, but ...

That could be interesting, I am in the UK ... UPS works fine between the two ...

Hi, I have a supposedly good (at least gas-wise) 25W that blew one of the FETs, the previous owner then changed the FET but it blew again when he turned it to full power so he suspected some tuning was off. I´m probably not ever getting around to fixing it so I´m open for trades. Where are you...

Well, scratch that. I fired up the "weak but two good RF drives" tube, it pulled 13.5A, showing both drivers are alive ... it is weaker than expected. A slight burn on cardboard that becomes non existent after about 30 seconds CW, the tube is close to dead. The second tube, I fired up with...

Glad to hear the AD633 rotation circuit is working. That is a fun and exciting circuit, not previously available, to my knowledge. Thank you laserist. You should get an award for your drawing. Kevint: Did you get the continuous turn sin cos pot supplying the rotation signal? I haven't tried using...

To the best of my knowledge that is the first picture of the inside of one on the internet. Steve..
