Works for me....
i made it = 5 v for the core PIC, drivers, etc... ( i take off the 5v regulator too)
24 volts for the charge...
Why, because most of the wired strings leds on the market comes with 24 volts after the provided transformer and tricky command box....
So it runs perfectly for me....
Inconvenient : you need a PSU with 2 regulated voltages or better : small one 5V out and a big one 24v for the mosfet drain current...
In all cases, it was great, as i can use standard 10m led (100 led) strings from the market who cost around $7 unit including the shipment cost from CHINA....
I love DYI.....
