Raspberry Pi Zero FPV and OSD system
IoT / Open SourceRaspberry Pi Zero and camera weigh 13 grams making it an ideal setup for data logging, HD video recording and custom On Screen Display for FPV.
I have created a full system that I put on one of my quadcopters and had a few successful flights, recording HD footage while seeing helpful OSD information on a display.
You can follow the project and get source code for it on Hackaday
