Hi All
I've been breaking some Martin Ego 3 lighting fixtures as the motors are still sought after for spares.
There is a main kaleidoscope assembly in them which comprises a fixed trianglular mirror tunnel, and a rotating tunnel, driven by a 50:1 geared 12V motor.
In action there was a gobo wheel too, and the combination of mirror tunnel and gobo was pretty good. Unfortunately the boards were fragile and uneconomical to repair (multi layer) and expensive to replace (~£180 for a board for a fixture that was ~£260 new)
As you will see from the picture, there is a space for another motor to be mounted, so this assembly could provide a platform for a counter rotating grating pair plus an additional wheel of some sort.
Anyway, I was going to put the motors up on eBay separately but I think they may have some use to people here as full assemblies.
Drop me a PM if you have questions.
Cheers
Adam
