Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Electronics : so what's the furthest you've done a radio link with fleabay modules?

Quite an interesting read.

and, largely unrelated but a face-palm, this was linked from that article... https://www.theregister.com/2021/02/19/airspeeder_alauda_drone_investigation_with_photos/

the pictures of the quality of work are shocking.

Pictures are truly staggering - erk....  

Those prototyping boards should only ever be used to prove a concept on the bench IMHO.  Most of the prototype things I build, I still design an "A" variant PCB for them, then fix anything I find wrong in the "B" variant.  Point is, I get a professional PCB made even when I am prototyping anything.

I don't think I would be comfortable designing wireless links for a drone though, cos as this case has shown, one bad bit of design COULD potentially put commercial aircraft at risk - that could have ended REALLY BADLY if it strayed into the path of an aircraft....yikes....

In addition to the kill-switch, I would have liked to have seen at least some kind of altimeter kill-switch thing, so if you lost all wireless control, and it happened to climb higher then a certain height, the altimeter thing would kill the power, and the drone would fall out of the sky - but not be able to climb up into the habitat of the commercial aircraft.

But then, I would not be doing drone controls anyway!
