At Gantom we have no intention of ever producing a moving head light. At the thought of this our mechanical engineering sense tingles and tells us that moving parts break so we should stick to solid state. Despite this, it is widely accepted that our fixtures would look adorable on a moving head. We were torn. We settled on 3d printing a prototype moving head that would fit a Gantom iQx micro gobo projector. We took this to USITT 2015 so folks could leer at it. Now, it belongs to you, the people, so you may share it with your friends and lovers.
Obviously, one major design constraint with any electronic systems integration is the various voltage requirements of the components. The iQx runs at 12v dc, and the Skulltronix board and servos it controls and powers run off 5v. When I realized this I fell into a deep state of despair, but then I remembered voltage conversion.
I used as a voltage conversion board that we already had lying around. I forgot the name of the board and I would look but someone stole it. (editor's note: i stole it and then usps lost it, sorry)
To get the servos moving using DMX input I used the Skulltronix Board of Chuckee ($90)
If you build this, find about the slowest servos you can.
I used the round servo horns that were included with the servos to attach the moving parts to the servos. I used screws that came with servos to screw all the other parts together too, including holding down the boards on the inside and screwing the lid down.
I made the model in Solidworks 2015, and I have made the files available in various formats.
I printed this on our PrintRBot Simple Metal with PLA filament.
