David Duffy Posted April 21, 2009 Share Posted April 21, 2009 A DMX controlled mirror ball motor is on my "to do" list. I have the motor unit and have already designed the PCB. Just have to write the code for the micro now. Ah too many projects, not enough time! Link to comment Share on other sites More sharing options...
Brian Posted April 21, 2009 Share Posted April 21, 2009 did you buy them then?Nope. ...Light Engineering advertise a DMX controllable rotator rated at 100kg SWL....As of when I was looking last year they'd never actually made one. Link to comment Share on other sites More sharing options...
Dmx512 Posted April 21, 2009 Share Posted April 21, 2009 We did this last year with our macs complete control Regards......Dave www.q-lights.co.uk Link to comment Share on other sites More sharing options...
Jivemaster Posted April 22, 2009 Share Posted April 22, 2009 PCB from http://www.milinst.com/DMX/dmxtext.htm stepper motor from RS (et al) and 500Kg rated bearing from your favourite rigging supplier. Link to comment Share on other sites More sharing options...
lxhipster Posted April 22, 2009 Share Posted April 22, 2009 yeah I had thought that mirror ball technology was probably not 100% ideal (even a vidiot like myself can see that mirror balls are not exactly precision engineered devices!) the robe banner rotator looks like it would be perfect if only it cost a bit less, don't suppose anyone knows of any cheaper alternatives to the robe? or... has anyone got any broken macs which still spin round? that could be the most affordable option for the proof of concept stage I could point you to chinese companies who manufacture Robe Spinner copies if you want.Not quite sure if it really does take 50kg or would spin at all.

sleepytom Posted April 22, 2009 Author Share Posted April 22, 2009 yeah I'd like to know about the dodgy Chinese copies, I don't normally think such things are worth using but I'd be interested in getting a price from them. if it is cheap then I could get a unit for development of the idea at least, though I doubt I'd want to use them on actual shows.

Kinell Posted April 23, 2009 Share Posted April 23, 2009 See if you can get a spares only mover and use the base unit and yoke as your control, in 16 bit you should get the control you need. A bit of re engineering might be needed to get full 360 rotation though but as you don't need the control cables going to the head you may be able to remove the stops and re direct the gobo control to the rotation motor. Sounds cheaper than other options. Shame you need control of where it stops else you could just run a standard motor off a dimmer. Link to comment Share on other sites More sharing options...
