Who knew the dogloids can be produced by simple pendulums. Not I. I found this video: https://www.youtube.com/shorts/Obo9Vb0dahs Hey, I'm always up for a weekend call with anyone here to chat about lasers, the universe, and everything. Steve, email or pm me a number and time, and I'll place...

crowd funding made the radiator possible. ymmv.

DIE-ONICs. Cute, I hadn't heard that one. No, this Laser Ionics Model 554 mixed-gas laser was for a static planetarium installation. I agree entirely on what a pain in the ass it must have been to service it. Luckily, the planetarium client bought the laser, I designed and built the 4-color, 3W...

Ok, I can't resist, starting a new thread

You performed shows with a DIE-ONICs ? You have my utmost respect... (Laser Ionics, notorious for broken gas reservoirs when traveling, but highly cost effective in use!) Not easy to change the tube, as it was glassed in through a hole in the resonator base. If I'm wrong, that is the other blue...

There are also plenty of people in this industry that have funds who would invest. I'd invest hardware and shop time, in a Heartbeat, as that is what I have. . You should not even think about crowd funding. It often doesn't end well. OK, well, sometimes it does, but not often. "Hey there...

Yes, its been done before, this from my design ~1983-1985.

this is where the small world thing comes into play. the person who made the post on metafilter (hippybear) is an old friend of mine and i just discovered his "about" page lists to some of my laser shows. crazy, man!

Thanks mixedgas for this insight into today's high quality mirror balls. It is a far cry better than those from the old days...square mirrors glued onto Styrofoam spheres. I loved seeing them form the aluminum shell halves.

Been busy with family and church. Started hardwiring stuff together. It is going to take a while to put all this stuff together, so my posts maybe infrequent. I am sill interested in adding rotation and other effects but that will come later. My goal now is to just get a stable working...

I have a job interview this afternoon. I'm not even hired yet and I already have a cheap shit recruiter out of DC data mining me for a position in the beltway. You might have got 990,000 hits from one URL trying to scarf what your doing. Steve

Greg, I have read this thread and the CYGB-A multiple times. It has been an inspiration and I have learned a great deal from them. Thank you. Regarding the video links. When I click them in the thread they are not working for me.

At this point in time you may want to keep the tech details of your software work product more closely held. There are some real vultures out there. Ask me on the phone some time about laser harp development, and who really did the work.

i am on this thread like a cheap suit.

I'm a bit puzzled by the number of views of this thread, which has shot up by the better part of a million since the last postings a couple of weeks ago. The samples of my work on youtube which I post links to here only get twenty or so views. I don't care a toss about getting views on youtube, but...

Hi Steve, The scan head we have came with a MicroMax ST-133 5MHz unit, which I believe they intended on using to drive the galvos. It's made for use with particular cameras, not for scan heads (which makes it odd that it came with the scanner). Have you ever seen something like this be used as a...

SELEM is not the same without you, Zak! Look into Amtrak from Richmond to Wilmington, DE. You can do round trip for about $84 (coach flexible fare).

Been 5 years since my last Selem Hoping to make it this year but I'm going to give it a 10% for me :/ Anyone happen to be driving through Richmond on their way? looking at my options to get there as I no longer trust my car for journeys longer than 30 miles LOL long story. Alternatively looking at...

Something different, open to suggestions. Displaser

I’m working a few today, will upload soon. Greg / Displaser

Company is here, and they make more then mirror balls. https://www.nissho-osk.jp/ The circular mirror on that ball makes it a lot easier to do the legal audience scanning calcs, hint, hint . Especillay if you just overfill it, Transfer Functions and ABCD Matrices are the key to Gaussian ...

Wow - those things are *BUILT*. I've only ever seen the styrofoam balls with the square mirrors. Obviously those are much easier to assemble though. Everything about these things is complicated, from the metal forming necessary to get the dome shapes, to the painstaking trimming of the...

I like the hybrid design from Shadow & Lazerjock, but I must admit that I also like the one from MixedGas, as it's a throwback to the original SELEM logo from 2007. Does anyone else have any submissions? Adam
