Hi guy’s,
Just wondering if anyone has modified a Chinese 27 channel dumb RGB controller to run two separate voltages? In my case 24v and 17v for some custom light strings.
I’m thinking it might be as easy as cutting the +VE track and soldering on a separate supply wire to how ever many channels chosen, but are there any problems / issues with doing this?
Any help appreciated.
