I have never seen a slotted can galvo, but the thing in the photo is what I imagine one would look like. Or is that the round aluminum disk about an inch in diameter with a 1/4 inch hole on axis that is part of the joystick? Shown in the photo is as much as I can get of the joystick together. I...

What ever came stock in them. C

What galvo and scanner amp is installed? Steve

Well done… amazing.

Wow! Absolutely mindblowing.

Superb! Absolutely superb!

two radiators and lsx... all being driven from the lsx timeline.

I'm sorry I missed this, otherwise I would have been more prepared for Gabby & Nick. Vegans require a bit more planning while shopping and are hard to do on the fly. Especially to ensure they're getting adequate protein & macronutrients. I'm not a dietician so I'm not as well versed in what to...

Price reduced for quick sale

This is still available for sale.

My approach from the beginning was to create my own set of data types in C++. Since each and every aspect of a frame_set is made of C++ classes (objects) each one can have a set of functions and overloaded arithmetic operators defined on it. So apart from the actual data itself of each frame in a...

Determining where to start and stop a laser scanned, rendered line drawing that has blanking between line segments has always been the challenge and the 'artful' aspect. The more line segments the harder and more complicated the task at hand. The bigger the "jump" between segment end-points and...

That looks really nice, Adam! Can't wait to see some "action videos". The size of my "original box" was dictated by how large of a diameter hole my drill press's sliding-arm circle cutter could cut. I would agree that the bigger the "box" the more exponential the work to make it is, along with...

Something else that comes into play is where to start. You have to start somewhere, so for the first frame in a set, I thought the end of any lit segment that is closest to the origin. But once you have committed to that, then it's a matter of what is closest to the other end of that lit segment...

the traveling salesman is doing the drunkard's walk... just to make things even more of a challenge.

Delicious and appropriate are the words that come to mind. Good Job Brad...

So the Echoes show, if there is one, would be Saturday the 5th?

Hi Adam From what I could tell from singlemode's stream, SELEM was an incredible event, so I'm planning to attend next year's event, if'n the creek don't rise. Is there a site where we can find uploaded videos of this year's event? Thanks to all who are willing to share.🙏 😎

Indeed. You are essentially trying to solve the traveling salesman problem over and over with each frame, in real time... (And of course, the traveling salesman problem is NP-complete.) So, yeah, it's already a computationally-intensive problem, even before you start thinking about advanced...

Another SELEM has come and gone! If only I had gotten more sleep... :rolleyes: I finally unloaded my gear last night. I was just too tired to do it on Monday. (I thought this stuff was supposed to get lighter now that we're all using diodes - sheesh!) Thanks again to everyone who helped...

I build one of these for my son (Dan) last fall and gave it to him as a Christmas present. I've been meaning to put up a post detailing the construction process, but I haven't found the time. Here is a picture of the completed project: Direct link: https://i.imgur.com/dDmqG0a.jpeg I...

I don't remember seeing fringing like that on any of my Plutos. It's almost got to be contamination on the lens. Here is a side-by-side shot of two Plutos: On the left you have 463 nm blue and 520 nm green, and on the right you have 445 nm blue and 532 green. No fringing on either...

I watched this at SELEM this year, and I was really impressed. I guess I didn't know what to expect going into it, but I very much enjoyed the documentary. I think most laser enthusiast's have at least a vague understanding of what Laserium was, but this film dives deep into the history of...

Both I and Dale have the isotopic neon and helium. Start with Dale and then call me if he cannot help you. Looking at a 132 picture, the advice of dropping in a new tube is a bit more appropriate, due to the way the soft mirror seals are sealed on a glass tube with the flat ends precision ground...

Thanks Ron, That is more than enough. This amplifier is a work of art. The output topology is amazing. What more can I say, I stared at the schematic for a full hour and then said a Prayer of Thanks for the beauty! I shipped a little something surplus to Greg. He's going to need quite a...

That was a "gentleman" I could have done without meeting. We'll leave it at that. Steve

Not practical. Waaaaay cheaper to just replace the laser with modern He-Ne, and keep the old heads in a display cabinet (with cover off?).

dale harder or steve Robert’s. I just gave them each a 1000 liters of neon. Dale has direct experience repumping both.

The guys in R&D were developing those after The Beatles show premiered. Ivan brought Sam M. in as president, and Sam negotiated the Beatles licensing deal. Looking back that was pivotal time for Laserium, but Sam didn't have the slightest idea what Laserium was about, was profoundly hard of...
