using the RP2
and

as a power supply.
I have 90 leds connected.
Any idea why i have from while to while some flickering leds with random color? seems like it is an electrical problem but i cant figure it out why...
My next steps it trying to use an external usb hub with external power source .. maybe this is the problem?
Any idea what else can i do?
