Short demo of GDEMU v4 prototype in action.

[cybdyn]

possible. try use DC-DC converter ic "7805" , there is model w/ 1A output current.
a similar one is used on the native gd-drive board. so we can use 12v to get 5v , as power supply of HDD.
but better use some kind of heat shield to dissipate of heat from convertor
(it's in theory, i'm only going to use such scheme in future)
