Brilliant! I've managed to glean this much, the yellow wire is the common positive & the others are all negative (Many thanks to Matt Thorn for figuring that out ;)). I'd assume some will be to control the steps of the LED string & the rest will be for the impact activated flash effect. Best to wait for details from the source though. Thanks for your help Subvirtua, I look forward to hearing the results of your enquiry. :)
Edit - You're right about the accent LED's, perhaps I could run them off the rumble motor output? Failing that a micro LED driver like the ones JQ Sabers sell could do the trick wired in parallel to the main board input. I just want to run a pair of flickering 3mm LED's to give the inside of the Graflex clamp a furnace type effect which would be visible through the mesh of the blingstrip.
I wonder if 1.5A would be enough to run 2 dies on a Ledengin 10W amber either in series or parallel?
