My hobby is to fly rc planes and drone, I was wandering if it's possible to hack an fpv osd.
What I think will be interesting is if I can make the osd with the help of an arduino to talk to me in critical conditions, for example when I'm flying low under 50meters, or when I have an over speed, or no gps signal etc.
I want to hear a voice saying OVER SPEED, FLYING LOW, NO GPS etc.
I want to know how will it be possible to get the data from the OSD in to the arduino and have a sketch that will identify the low altitude, over speed (over 50km), no gps signal etc. and when it dose to play a corresponding mp3 file .
Thank you for your time !!!
