great video. However, I read that the protection against excessive voltages is bypassed by supplying it via GPIO. How risky is supply via the GPIO pins?
I have U100 ups board, and if batteries are discharged, voltage drops to levels that don't allow rpi to boot. Could be the same in your case. People overcome it by increasing voltage to 5.2v or 5.3v

I bought geekworm 728x, so ac led fail is turn in red, what could be the problem?
