I bought two ESP32 UWB DW3000. Those can use Ultra Wide Band to estimate with a very high level of accuracy the distance between them. UWB is used in Apple Air Tags and is seems to be a very good topic to cover in your videos.
I can already say that I approve this suggestion, because (a) it's been suggested before and (b) I also bought two modules, perhaps the same ones you did (the Makerfabs modules).
So you have a winner here!
