Nicktaylor Posted July 28, 2006 Share Posted July 28, 2006 As I have loads of these projectors and disks, I wondered if anyone can point me in the direction of a controller for the speed. Obviously the current drawn is tiny compared with a lantern channel, and I am of course aware of the mechanical adjustments on the effects. It would be handy to vary the speed of the effect electrically. Link to comment Share on other sites More sharing options...
robloxley Posted July 28, 2006 Share Posted July 28, 2006 You could look at a VSFX to replace the Patt252 housing, for DMX control Link to comment Share on other sites More sharing options...
Brian Posted July 28, 2006 Share Posted July 28, 2006 Or replace the motor with a stepper motor and drive it from a Milford Instruments DMX-Stepper control board. Link to comment Share on other sites More sharing options...
dbuckley Posted July 28, 2006 Share Posted July 28, 2006 The standard 252 effects unit uses a small syncronous motor to drive the effect, as do some gobo rotators and mirror ball rotators. These motors lock to the mains frequency, and thus cant be speed controlled by any of the normal methods. The only way you can control them is by varying the frequency of the power supplied to them. One can purchase electronic motor speed controls (usually called inverters) that control motors (normally larger than a gobo motor though!), but I am not sure that this would work for this application, as I've seen what an inverter output looks like on a 'scope, and I'm not sure a little syncronous motor would run on that mess.

James S Posted July 28, 2006 Share Posted July 28, 2006 Usedlighting had a model train controller for sale a while back that had been adpated for this purpose IIRC Link to comment Share on other sites More sharing options...
