JohnYayas started a poll Anyone using anything older than Windows 10 these days? in Programming and other assorted Bit-level Alchemy

There has historically been a good bit of people clinging to older OSes on here in order to support older hardware and software. I still support Windows 7 for Spaghetti which prevents certain new functionality. I'm curious how many on here are still using anything older than Windows 10 for daily...

nulltrope started a thread Recommend an RGB Analog module for DIY system in Lasers, All Kinds.

Hey there! I started this hobby a few months ago by building a DIY kit mostly with cheap parts from Aliexpress. A no-name 30k galvo scanner kit (with controller/driver, SD, DMX, ILDA input) and one of those all-in-one 500mw TTL RGB modules. While things are working decently well, i'm looking...

I think this maybe the first video I've watched from start to finish here. Much more successfully tied to the musical cues than the rest of modern stuff I've seen. Nice work.

buffo replied to a thread Advice Needed – Safe Laser Setup for Interactive Art Installation (on a budget) in Help!

That does change things, from a regulatory standpoint at least. I'm not familiar with Canadian law in the slightest, but I've heard people explain that the regulations for lasers in Canada are similar to those in Europe, which is to say that they're not nearly as restrictive as the US regulations...

Here's a new show. It's a combination of LSX and Radiators. It's a three projector show with two 30k projectors on Radiators and a 60k projector for LSX native content. The Radiators are being driven via midi from the LSX timeline. Hope you like it!

blueUni replied to a thread Advice Needed – Safe Laser Setup for Interactive Art Installation (on a budget) in Help!

I’m not really worried about the CDRH. Even if I want to follow U.S. guidance on laser safety, I’m in Canada—so as far as I know, I’m completely outside the CDRH’s jurisdiction. 🙂 From my research, the process of acquiring and using a laser in Canada seems much more relaxed. That said, I’m happy to...

Cool. In case you haven't noticed, bottom center of all their product pictures that are inside a box, is a hidden mouseover link to more details. You're probably getting a chat panel popping out for assistance. That's probably Phillip, CEO & very approachable tech support. Don't avoid asking him...

Ever since you posted that Sparrow URL, I have been looking at their stuff. I have been considering buying modules from them. I'm sure my alignment drift is not just the kinematics. The diode mounts are probably not great and I have no idea what alloy the aluminum base plate is. I'm sure there...

Slide replied to a thread Source for Lenticular and "Fuzz" scan through materials? in Lumia

Cutting with a tube is a great idea. I drilled the centre out of an old school 1&1/2" thick mirror blank to have the option of turning a Newtonian into a Cassegrain. It worked well, bit slow going but did the job. Thanks for the source. Craig

TheHermit replied to a thread Hypothetical white light diode in Advanced Technical Discussion

I agree on all points, without disputing Brian's suggestions for creating an optimal beam profile, if starting a projector build from scratch. But, all of those components probably won't fit inside most production projectors. Yeah, who doesn't love TEM00 beams from ion lasers? I love just watching...

absolom7691 replied to a thread Hypothetical white light diode in Advanced Technical Discussion

While I love the idea of adding a spatial filter and corrective optics, adding more elements to the optical train would add complexity to alignment for sure. But, to homogenize the beams, this would be a great way to do. I was just hoping for something better to exist. Don't get me wrong,...

laserist replied to a thread Hypothetical white light diode in Advanced Technical Discussion

Design/adjust the individual diode collimators to have the same divergence. Mix the the beams, run the mix through an apochromatic spatial filter with a input aperture to limit the incoming superimposed beam diameters to the smallest present and then through the spatial filter aperture to clean up...

absolom7691 replied to a thread Hypothetical white light diode in Advanced Technical Discussion

Constant tweaks of alignment aside, the thing that really sparked this was Pangolin's Beam Bush. It's such an awesome looking tool until you see the different beam profiles exaggerated by the Beam Brush optics. Now, I'm sure in some instances, that effect is cool but I would rather see one...

I am *very* grateful that you take the time to make these available, Chris. As for the price, I seem to recall that the first year you made these I suggested you charge a bit more for your time, considering all the effort that goes into making them. Back then, you said that you wanted to keep...

buffo replied to a thread Advice Needed – Safe Laser Setup for Interactive Art Installation (on a budget) in Help!

The problem is the strict US Regulations governing laser products and laser light shows. This adds cost and legal liability to any public laser display. The projector itself must be certified compliant under a laser product manufacturer's variance (which is rather painstaking), and then you...
