garyfunk Posted January 25, 2009 Share Posted January 25, 2009 I am really interested in what others use the LOR unit for, OTHER THAN automated lighting displays. So far, most everything is automated lighting. Link to comment Share on other sites More sharing options...

Paul C Posted January 25, 2009 Share Posted January 25, 2009 On cue, I mean sequenced to music. Using isolation relays, set off a Testers rocket igniter's that inturn set off fountains and stuff. Admittedly there is some timing issues to over come. LOLJust did a little shopping found that Testers does not make igniter's anymore. They are made by Estes and are about a buck a piece, ouch$. Still doesn't matter how it blows up just as long as it scares the heck out of some unsuspecting drunk neighbour.hee hee hee Link to comment Share on other sites More sharing options...

I have read myself where it hs been talked about where a diode should be used, but I dis so reguardless and luckily it worked out okay. Although that may not always be the case.Yes, a diode should be used on DC relays, DC solenoids, and anything that is a DC inductive load.Current flowing through a relay coil creates a magnetic field which collapses suddenly when the current is switched off. The sudden collapse of the magnetic field induces a brief high voltage across the relay coil which is very likely to damage transistors and ICs. The protection diode allows the induced voltage to drive a brief current through the coil (and diode) so the magnetic field dies away quickly rather than instantly. This prevents the induced voltage becoming high enough to cause damage to transistors and ICs.What you do is place the diode in reverse IN parallel whit the load;It is called a Protection diode or snuffing circuit.I have taken a 12vdc relay and have measured a 90 volt spike. :shock:A 10 cent diode VS ....

BadSCR Posted January 25, 2009 Share Posted January 25, 2009 Yha, it surprised me too, even more so after i grabed the wire before using a Meter.Keep in-mind it is for DC applications not AC.using a a Diode like that on a AC would not be goodhttp://www.allelectronics.com/http://www.goldmine-elec.com/http://www.nteinc.com/ Link to comment Share on other sites More sharing options...

BadSCR Posted January 25, 2009 Share Posted January 25, 2009 Yes, there is a few ways to.#1: I can't remimber what it is call; I think it starts with a "P" poaching?.Basicly you reverse the motor for a split second and it will stop the motor vary quickly.#2: Regenerative Braking Link to comment Share on other sites More sharing options...
Paul C Posted January 25, 2009 Share Posted January 25, 2009 I can remember a old Champion mixer that had a contactor that would pull in and short all three phases after the main contactor droped out, slowing the motor only a little.Anyway more uses for LOR, sorry.

BadSCR Posted January 25, 2009 Share Posted January 25, 2009 Here is a idea. LOLAdd to the LOR controller a clear window, some LEDs, neons, and a strobe. Link to comment Share on other sites More sharing options...
BadSCR Posted January 25, 2009 Share Posted January 25, 2009 Here is a good idea.Use the LOR in the Shower to control multiple shower headsthen you could use DMX to control the direction of each shower head (servo).http://www.bpesolutions.com/dmxproduct.html Link to comment Share on other sites More sharing options...

The problem with all of these ideas is they can't be used in real-time. Link to comment Share on other sites More sharing options...
Paul C Posted January 25, 2009 Share Posted January 25, 2009 You could use servos to drive the heads. Link to comment Share on other sites More sharing options...

Paul C Posted January 25, 2009 Share Posted January 25, 2009 It is my wish that LOR come out with a analog input card. Link to comment Share on other sites More sharing options...
BadSCR Posted January 25, 2009 Share Posted January 25, 2009 I like that idea of a LOR analog input card.Yha, every-thing has to be pre-programmed, so you can't control it in real-time, Buy it would be fine by me just to have pre-set patterns.Even with the idea of the "Home Theater Special Effects" doing each movie like you would a song for the Christmas light display.Have some Strobes, Lighting, Fog w/ chiller, Penumatic hooked to the couch (ie Motion Simulator), and more. It could be a completely immersive environment. Take the movies to new hights. Link to comment Share on other sites More sharing options...
