Hi Everyone !
So last week, searching for DJI FPV alternatives, I discovered OpenHD. I was thrilled !
Announced latency seems a little high for me as I’m flying mainly small quads (I have a light 6", a 4" and a 2,5"), but I’m diving into this now, betting that it can only get better. Feel free to break my expectations.
My goals are :
To get a grip on OpenHD with a “simple” setup, with only the digital video link on 5.8GHz, with minimal investment (time and money).
For this, I intend to equip my 6" quad with a Pi Zero, OV5647 Pi Zero Camera, and a TaoBao Wifi Module.
For the GroundPi, I’ll be repurposing a Pi 3B and another TaoBao module
When I succeed at goal #1, I intend to push the project further, to achieve something like this : https://www.youtube.com/watch?v=BEfj799LDbI
(Digital FPV with headtracking on a 1100mm plane, for aerobatics. In this video, the guy uses DJI Goggles Race Edition)
I have a few questions :
- I’ve just bought FPV Goggles with 1280*960 screen resolution (Sky04x with HDMI input). Will a Pi Zero on the Air side and a 3B on the ground side be able to stream at a suitable data rate to match that native resolution ?
- I’d like to keep my 2.4Ghz Frsky setup for RC control. Will I still be able to use the OSD ?
