Bump for lowered price OBO.

that’s a weird request. Most people want 1mm not 1 “. What is the application?

1-inch diameter circular is enough. The output should be pretty well collimated. I have put together one with adjustable mirrors myself using Thorlabs parts but I need a more compact unit. All lasers should have the same polarization.

More detail. One inch square round rectangle. Power divergence use?

Greetings, all; I'm back and catching up on stuff. The other photos from Canal Convergence of my installation Soleri, So Laser, are to be found here: http://mondodyne.com/1SSLwww/

good work please send me ilda file at laserev@hotmail.fr Thankyou ! Best regards .

I know some companies are over the top creative in their marketing. Any suggestions what im actually is? If it is the real deal, it might be worth investigate. https://www.ebay.com/itm/Brand-New-Sharp-520nm-500mW-Green-Laser-Diode-500mW-TO5-9mm-Diode-1-pcs/264557183792 Datsurb

... today I've installed one of our laser engravers with a 30W MOPA and 300x300x200mm XYZ "marking range" (200x200x200mm and a 110x110mm galvoscanner head) at university Augsburg for the "materials research" group ;) Viktor

Great info on the color mod, I was just going to ask about that. Ron and Brian, thank you immensely for continuing to share your wealth of knowledge. The emulator now resembles the original circuit more closely than prior to this most interesting discussion. So... if anyone is interested in an...

how do I get it to go from chinese language to english? nvm, Found it... works well measured the values of the POTS and replicated it on the board i screwed up, hoping for a baseline to learn to tune from....

The angles in the image look consistent with the perspective and foreshortening effects you'd expect from an image of a long-distance laser projection. You lose a lot of perspective in a photograph versus seeing it in real life. That doesn't mean it isn't fake, but I don't see anything in the...

That image is a time exposure of an image that has two nodes, but was rotating over time. (Where your example has three nodes, and stable) I was playing with the mark 6 looking for different "stuff". The mark 6 had six switches in a horizontal row over the beam tourquer knob The first three summed...

Single scan pair... In which case I don't know how you did that. Did fm on an osc have an effect on the modulation signals provided BY that osc? For example, bottom osc is primary with am / fm by center osc. If then center osc fm depth is brought up, then top osc frequency modulates center,...

Look at the angle of projection. That looks like a fake to me. Isn’t that like one of the tallest buildings. How did they project at that angle? Oh and it’s on Windows so where is the back reflection....and what is the ufo in the top of the picture. And the other one on the left being hit by...

Smells like a fed looking for someone to earn his pay for him.

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...

^^^ What aberry said ^^^ but . . add high quality glow in the dark paint and . .

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.
