I'm really interested in this new design, because the original design makes text on bright surfaces really hard to read. The DimOn and DimOff is nice, but if you dim to hard it obscures the image too much.
I'll bet SimpleOSD also gets quite hot if you run it with 4S and use the onboard regulator to drive GPS etc. The regulator on Arduino Nano is bigger as far as I remember, but I don't like me equipment getting too hot.

SimpleOSD also uses resistors for voltage-divider. Only difference is, on SimpleOSD they are already soldered on the board, here you have to do it yourself (see battery-circuit 1 and 2, no magic here).

MAX7456 is not DIY friendly, so I'm not quite sure what to do with the project..
