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...) 
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)

Comments
i dont think that there is a visca cmd to do what you ask
but you can program it for a specific ppm
featured on hackaday
Excellent work and documentation! A very useful project for the community.
I was wondering if there is a way to control the camera zoom level i.e. x2, x3…etc, by sending absolute PWM values for each zoom level. That would certainly be a huge added value.
Good work elad. I too was working on a similar unit (FCB-EX980SP) up to eighteen months ago. Other things took a greater priority as they do! Your post has prompted me to revisit this. Although I have not yet attached it, I also purchased a stabilization output module so I can use as much of the superb zoom these cameras have as possible!
Excellent work !
I have been looking for an implementation like this for some time now. I have a Sony FCB-EX1010 and by using the support PDF, I should not have much difficulty making it work with my setup. I was also thinking about a way to wrap some of these commands into a MAVlink stream and have access to some of the other features of my camera such as switching between NIR and full color, similar to the features I'm used to with the RQ-7b system I operate.
Thank you very much for this!!
many thanks
those kind of comments makes me continue building things and how to replicate them
also the visca pdf i used to make the code can be found here
also forgot to mention it but i used a 3.3v to save the use of another component
if i used a 5v version then i had to use a 3.3v level converter or couple of resistor to talk with the camera
I used one of these cams myself and they're great for surveillance applications on a multirotor/heli at a price of $300 or so plus the arduino and other electronics. The zoom really needn't (shouldn't?) be more than 6x, because the vibs and movements will interfere. I have the feeling your sketch here is going to be referenced by other builders in the future. Great work!
