Hacking an LED drape? Chauvet Sparklite
« on: December 30, 2016, 11:47:38 AM »

We have Chauvet Sparklite LED drape installed on a multi day show. The driver unit died. Probably the main power supply. Can't get a replacement fast. Anyone have a guess how to hotwire the drapes themselves? 5pin xlr goes from the driver to each drape panel. I'm guessing DC low voltage current is sent on different pins to make different intensity for the Red, Green, Blue LEDs. Seems like we could use a power supply to get at least a single color going just to finish the show. Any ideas? Thanks.

I see on the IEC power connector a place for the fuse on the power supply was this checked and replaced with a known good fuse ?

Yes, I confirmed mains power is present beyond the fuse and power switch. No fan, no menu, I will have it checked next chance I have. Hoping for a way to power the LEDs so our drape is not dark the next 3 show days.

Most LEDs are not driven with pure D.C.  Usually it is a pulsed signal with the duty cycle variable for intensity. If you try D.C. , then be sure to current limit or you may fry it.

Thanks. did not end up experimenting with this. The controller is in the shop. Hopefully it can be repaired. I was hoping for a simple solution to get a static scene on those drapes. They were dark through the whole show...

Perhaps it would be worthwhile to see how much a spare/backup controller-power supply costs. (Depending on how important the LED drapes are to the show.) YMMV.

Yes.. looking into the cost of a spare controller. So far no luck as these were discontinued in 2014.

It DIED again! first day of a 5 day event and no sparklite in my drapes... Anyone in NYC area have a Chauvet Sparklite drape controller we can rent or buy? ANyone have an old unit collecting dust somewhere. Would love to have a spare. Chauvet is no help since it's a discontinued fixture. Thanks.

Can you see if all 5 wires are actually being used coming out of the controller to the LED panels? LED ropes/strips operate on a 4 or 5-wire setup, so you might be able to get a generic PSU (that matches the output of the ADJ unit) and DMX decoder (Probably about $50 total) that could power everything relatively easily.

If you can find a pinout diagram that would be even better, I wouldn't recommend going full power as you can easily burn out emitters if they're wired incorrectly.
