    Default Wave lumia tubes

    For sale , for the next two weeks, starting Jan 13th

    Wave Lumia tubes, 5$ each plus postage for a 2" 18 mm OD tube. You'll need to supply your own motor. No two will be alike, your choice of twist or poked. I can also fill one end with casting plastic if you need a way to make a mount that fits on a mother shaft. Larger or smaller diameters by special request.

    here is a really sped up example:

    http://www.youtube.com/watch?v=j1U8YFFY57A, note it repeats, so you can move the beam up and down the tube and have reasonable repeatable but different lumia. Video is 250 mW 658

    Pm me if interested

    I'm interested but would you be willing to take a picture of what the laser image will look like? I want to see how different it looks than a normal lumia wheel before I invest in it.

    May I suggest a nice, albeit, WAAAY-not 'exhaustive', 'ref. library' of a few lumia / grating fx...

    Uh, 'Professor' (Steve) this might be a good 'chalkboard' for us to refer guys to, for specific lumia refs... ie: Gary, I am pretty-sure THIS was done with a 'torture tube' (the 'Sun') ...

    Anyhoo, hope this helps...
    peace...

    You'd need a movie, its a motion effect, back and forth, back and forth in a line perpendicular to the tube axis.

    Invest? At five bucks I'd have one just to see what it looked like. Steve, I'll buy one if I can get that pair of optics coated. Chad at Meredith says it will be ok to send them to you if I buy, so the tube can cross the ocean with them.

    Those images look a lot like the output of a Laserpod.

    I have one and they're quite relaxing to look at.

    Interested!! you might get more hits if this were in the buy/sell trade section?

    Hmm larger and smaller diameters.. Would it work well to have concentric counter-rotating tubes, or would the light become too scattered and ruin the effect?

    Its really a art tuning the glass with the torch for a given divergence. ITs easy to get big splatter, hard to get a small beam. I Imagine its possible to do counter rotating tubes, I had not thought of that. Greg Makhov at LSDI has something he calls a Zoomia, with a big lens, so I suspect if you add a lens to get the divergence down, two disks or two tubes would work just fine.

    Never tried it.
