Simple Spiro/Lumia Wheel Build

So after a bunch of messing around, I finally built my "Spiro/Lumia" projector ... I call it that because even though it has no spinning mirrors as a spiro does, the glass optic I used for the Lumia Wheel has layered pebbling that projects a spiro-like pattern, so the overall effect is that of a 3-D spiro rotating on all planes:

Sorry about the low quality video, as well as my not being able to figure out how to "embed" it - I was planning on shooting a nice one outside against the house last night but it rained like crazy (still is, as a matter of fact).

The build itself is based on 3 major components, an American DJ "Groove Wheel" fixture, an Aixiz 118mW green Labbie, and a "Water-Wheel" projection optic as used in the old design ADJ Topaz fixtures. The fixture is gutted, and after drilling out a few rivets and drilling some new mounting holes, the 3RPM motor is reversed in the fixture along with its' mounting plate. A few threaded nylon bushings and some easy light machining later, the glass "Water Wheel" is mounted on the motor (slightly offset and at about a 3-4deg angle from perpendicular to give it a bit of wobble and offset rotation) andthe laser module is installed. (In this build I mounted it high on a set of machined spacers to allow the addition of a couple of LPC reds in a custom heatsink to be mounted below it in the future):

The slick part of the setup is the "Water Wheel" - unlike normal pebbled glass, the pebbles are actually layered, which projects a simple "Spiro" image. As the beam tracks across the pebbling, it gives a twisting effect which gives the illusion of the spiro patterns rotating on many different axis - VERY cool.

The final build projects a roughly 12ft X 12ft image at 10ft, and is highly visible in darkness to about 30ft X 30ft, so it is more than adequate to cover a large portion of a dance floor, etc.

The build is a simple one, and almost any enclosure/module combination can be used, as well as a motor speed of 1-6RPM (after 6RPM it gets a bit squirrelly, and the patterns are nowhere near as defined). To order the
Water Wheel", contact the parts department at American DJ (or your local ADJ distributor) and purchase part # Z-CW/REF (around $16 shipped direct, or $22 through most ADJ retailers).

The next portion of the project is to reinstall the sound activation board that controls the motors' rotation (should be pretty simple, actually) and a simple 120VAC wireless control so I can turn it on and off without having to have it located near a DMX relay pack - but that's really no big deal...

Anyone that wants to contribute ideas or recommandations to make the project better, please feel free, and if you need any pointers on how to DIY, I'm just a PM away!

that is so bad ass, where did you get that perfect sized glass from. also to embed the video do this [.yt]videoid#here[./yt] don't put the periods though or the whole youtube.com com link like this http://www.youtube.com/watch?v=x73SduBIacI all you want is the last set of numbers after the = sign. good luck

here ya go brew

Can i give you a different idea ? (cause i'm specialized in crazy ideas, LOL)

put 2 (or also 3) modules one near the other, green, red and blue, but not joined as white beam, i mean just one near the other, and make them pass through the wheel ..... each one hit a different zone of the moving wheel, so you end with 2 or 3 different variable patterns at the same time, overlapping, with a single wheel.

Second crazy idea (you don't hope i've end them, right ? :D) ..... part of those lights are always reflected back, cause the glass isn't AR coated (and send it for have AR coating, at least here, it's a prohibitive cost) ..... so, just place a piece of that metalized plexiglass (those "plastic safety mirrors"), rear the wheel, with little holes for left pass only the beams, in this way, also the light that become reflexed back, become reflexed another time in front (see the attached draw) ..... more crazy effect (in my tests, anyway, it work better when the wheel is not too much, how i can say, "rugged" ? ..... too hard patterns ..... when it's partially transparent, sorry don't know how to explain better)

I'm also trying "net and oil" ..... some results, but have to find better combinations.

Dale, you did a FABULOUS job putting together a bunch of inexpensive parts. You then coupled your "creation" with an outstanding idea, to produce a "BAD-ASS" special effects machine, suitable for work (dj's) or play (at home). Nicely done, pal, NICELY DONE. You sure have a creative mind. +1 Rep for the whole deal.............rob
 
Thanks, guys! As to the multiple-beam setup, I have a buddy machining me a tri-mount for 3 Aixiz modules and a hole for the green beam to pass through, and I already have 2 LOC's and a 6X in modules with drivers ready to roll as well as a nice 10v 2A transformer ready to power them (I did a "down and dirty" pretest using one of my 6X's and a dilda and it's pretty cool, I just need to make sure everything is monted and secured correctly as I'll be using this at the shows)...

I tried the mirror idea with a few small mirrors glued together (just for fun, I didn't have any acrylic mirrors) and it really didn't reflect enough light back thru the wheel to increase the pattern, etc - then I tried a diffraction grating before the wheel and that definitely changed things, but not in a good way - the pattern got bigger but lost a lot of definition, oh well!
 
Yes, mirror works better with those glasses that have few waves and still transparence ..... your one probably is too "heavy pattern" for take any advantage from mirror, sorry.
 
You're right, it definitely IS a heavy pebbled pattern - I was planning on making my own acrylic wheel later this week if I get the time, that should be a bit more transparent so I'll definitely keep your idea in mind and give it a shot!
