for this demo I used 3.3v as power source for the receiver but in real life it will probably be a 5v power source so you'll need to figure a way how to do it (resistors, level converter...)
so let's start
what you need:
sony block camera (visca)
arduino (3.3v)
rc transmitter
rc receiver
monitor with av
fcb-ex11d
arduino mini 3.3v
rc transmitter - spektrum dx6i
ar6200
then you'll need to hook up the wires as so
camera rx to arduino tx
camera tx to arduino rx
camera gnd to arduino gnd
arduino digital pin 3 to reciever elev channel
then you left with video and power
power specs says 9v plus or minus 3v
and video is ntsc so any suitable
monitor will do the job
and of course the code :)

next thing will be to import it to attiny85
will release the code later tonight
**got really cool board that im using called attami (google it :) )
i was told that it will cost 1euro (not assembled)
and will be available at c31c (chaos communication congress #31)
code for attiny85 or attami :)
