Here is an update for the laser tube display/sculpture/monument/...
If you recall I tried sticking a strip of WS2812 LEDs behind it and the result seemed pretty good:
However this was laying on blanket in my workshop and probably not practical for the Space..
So I went about making something to mount it on...
But first I had to deal with the big honkin stickers on the tube:
Luckily they came off with some lacquer thinner, razor scraper and elbow grease:
I thought about various options for a mount and figured that it would look best displayed vertically as that hides the LED strip but allows the best viewing angle. I also wanted something minimal but offering some protection and support of the flimsy laser tube. I had some MDF scrap in my garage so started cutting it up:
Glued it up, clamped it together and fixed a botched cut in the wrong place:
Then I gave it a couple coats of white primer (which in reality will be the finish coat also):
I ended up with this:
This gave me a base for mounting it that had room for a power supply and electronics. Now I just had to make brackets to hold the tube. Unfortunately I got a bit carried away at this point and did not take any pictures. I made the brackets out of doubled up 1/2" plywood. I cut the round bit for the tube out with a jig saw and them trimmed it to shape with a small drum sander mounted in a drill press. Since I wanted the tube to be vertical I was worried about it sliding out of the brackets. So I added a couple metal L brackets on each end. The end result is this:
