This unit is indeed water cooled. 1.5 GPM. It’s a lexel 85. I think this one was built in the 80’s, I have another that was built in 1977. I suspect the tube was replaced at one point since it still works to this day! It sat in a barn for about 5 years before I acquired it. Got it cleaned up and...

I haven't fired this beast up for about a year. Thought y'all might enjoy. Still pumping out just shy of 2.5W at full current.

Hi all, there will be a Florida Laser meet (FLEM) next weekend in Tavares, FL. This is an event that is similar to SELEM but MUCH smaller with a very small venue. There will be plenty of laser shows and shop talk. All laser freaks are invited to attend! For more information you can send me a PM...

Ghostgeek, I hope that you will consider attending FLEM or SELEM at some point. Both are laser Enthusiast get togethers that occur in the southeast and it sounds like you'd fit right in. SELEM is held once a year in North Carolina while FLEM is less formal and typically occurs a couple times a...

I've always wanted to play around with HeNe optics to see if I could get something other than red from one. I recently noticed that Sam G. sells HeNe optics of various colors on eBay so I figured I'd give it a shot. I ordered up a set of yellow HeNe optics and spent hours trying to get yellow...

Neat! Maybe I'll swing by and check it out! [/sarcasm] Looking forward to seeing everyone again, plus some new folks. SELEM just keeps growing! Wish you could make it Hakzaw!

I figured some of you pointer guys might get a kick out of this: 6khJLEGizdo

Don't neglect the gas!

You can hook up a set of scanners to just about anything as long as the signal doesn't over drive them. Sometimes I'll connect the X scanner to a ~30Hz ramp and the Y scanner to the 1/8th jack on my iPhone and you can see an oscilloscope type representation of the music. I had to google the...

The projector I use has 2 scan heads and a set of single mode rgb diodes for each scan head. The scanners are G-120's, very old but still kick butt! One scan head had a rotating piece of textured glass in front of it and the other set is being driven by an analog synthesizer to create the abstract.

Lumia with a side of abstracts!

4 weeks to go!

Damn. That doesn't sound good. How many hours are on the tube? I doubt it was my old one, I know who has that. It suffered from a problem called the "Red Blues". Lots of red and lots of blue but no green or yellow.

I wouldn't bother messing with the alignment unless I knew for sure it wasn't making rated power. The last 300wc I had was quite high pressure after sitting for years. It had a total of 72 hours on it after being rebuilt. Once I finally got it started all I remember seeing was a blue line...
