[@matthew04101]

@@luciduous are you talking about the wireless solution, from head tracker to radio ? that sounds nice, but i'm worry about latency. servo is already slow and adding wireless latency might make things worse. i guess it should be ok for rc plane and cars. i'm planning on using it with quadcopter, so latency is very critacal.

Thank you mate. You kinda just accidentally helped me out with another project. I have been wanting to put an artificial horizon and compass on 2.5" displays in the cockpit of my 1/4 scale 20cc affordaplane but put it on hold because the form factor was just too large. The 33 BLE seems to be the way to go. Thanks! PS, I'm still using Fatshark/Trinity.

[@fpvcrumudgeon4576]

Fantastic. Those kids that we complained about spending all their time in front of a computer are just killing it now! I noticed on the github link they also have a link for a wireless PWM module for the transmitter connection. (personally, the section for a TX16s is a gift!). These hobbyist single board computers have allowed us to programmatically interact with the physical world, e.g. head tracker. The 33 BLE Sense, in addition to the 9-axis IMU have pressure and temperature. All one needs to do a DIY flight controller is one was crazy enough to do it. (Going to be hard to beat Matek!)

[@Painless360]

Both work, stereo can be easier to find.

[@k.o.0]

Curious you mentioned Jumper and OpenTX. Does the protocol really matter? Based on your information I assume all you need is any radio that has PPM capability? Protocol is irrelevant. The bottom line is the pan/tilt are simply going to chew up 2 channels from your radio and that’s all. Am I correct? Thanks for making this video. I am seriously interested to do it considering the simplicity of this setup and low cost.

[@Painless360]

The protocol doesn't matter as long as there are a few spare channels for the head tracker stuff... Happy flying

[@DesertFernweh]

I can't help but wonder, with the invention of small 360 camera is the need for a motorized gimble is coming to an end. The Trick is in the processing, you can't send the entire 360 video stream over the air, there isn't enough bandwidth. So youll need to have the processing done on the camera end (aka in the Drone or plane) and only the footage from the viewing angle you want to see getting transmitted.

[@Painless360]

It is an interesting idea and something like that was in the excellent Parrot Disco. I hope we see cheaper options that would work with the FPV systems we use in the hobby..

[@y_us_12]

Great useful video!!!! Already ordered Arduino. Could you also teach us how to transmit live audio. And please don't say to use analog fpv for that

Firstly, apologies for commenting on a 3 year old video! I have a question about head trackers and pan/tilt gimbals. I noticed on my first flight trialling this exact kit that when I'm banking left or right, the gimbal stays in its original position and doesn't move with the aircraft. Ideally it would need to stay orientated to the direction of travel unless I move my head to look around. Would you know how to resolve this? Cheers

That is how head trackers work, they only move when you move your head. What you are looking for is a gimbal. Check out CAMSTAB mode in things like Betaflight and INAV... Best of luck!
