I'm adding the works to my Bixler 2 and have a few interference questions as ideally, I want to build a nice little pod that can fit all the electronics in it that can be dropped into the top through the normal canopy.
The electronics I have are:
I was planning on the pod having the following levels;
Was then planning on probably sticking the 2 radios on either side of the pod (if possible for compactness).
From flying my Naza quad, I know GoPro's are particularly noisy and cause interference with the GPS, but the question I have is how likely are the video tx (5.8Ghz) and telemetry tx/rx (433hz) to interfere with anything?
Do they need to be placed a certain distance away from anything else? or can I build them into the pod too?
If they are better further away, will using antenna extension cables be suitable? or do the actual electronics need to be further away? is there any shielding I should consider?
Thanks in advance,
Have no idea how you are going to fit all this into a Bixler2. I ditched APM plans for mine and bought a Finwin Penguin instead.
I am now having the problem of making sure that I have no ground loops. With the Penguin I can separate everything so radio interference should be no problem however I do not know how the ground is treated on the APM.
When I was considering the Bixler2 I thought I could use copper or aluminium mesh as a screen. Are you going to mount the 5.8G transmitter in the tail?
I've built a little cardboard version of my stack that seems to fit everything nicely as long as all the electronics play nicely with each other with the idea of using a friends cnc machine to cut a carbon fibre version of it. At this stage, I wasn't going to mount the 2 transmitters far from the APM (unless I have too) as I want to try and keep it as a single lift out pod.
I'll take some photos on the weekend to illustrate.
I used the following on a Bixler 2 with great success:
It worked fine. Flew great in stabilize mode and auto WP and RTL with no problems.
If you want to see a bunch of flights with this gear check out some of my vids on youtube. Just search for duffnyc
I agree with Stephen that the Finwing Penguin would be a lot easier to work with space-wise. Or a Skywalker. I have two Skywalkers and the Bix2 and I intend to get a Penguin eventually.
I don't understand what is being discussed regarding grounding issues??? I never have any grounding issues on either of my 2 APM 2.5 systems, both with telemetry, FPV gear and minimOSD...at least not that I am aware.
