first post on here after finding the whole project a few days ago.
I fly racing quad-copters through fpv, (first person view)
so live view from a camera on the quad to fpv goggles.
so not too much of a difference but i thought i might tell you about all the hardware we use, namely micro fpv cameras, super low latency 3-20ms with wires so you can fit them anywhere, smallish size at 19x19mm which is pretty tiny for a high quality feed like these.
anyway, for optics we mostly use goggles which have 2 sets of lenses but there are some cheap ones we can take apart (although please don't use these as goggles, they are cheap for a reason) namely eachine ev100s, they have 2 sets of screens but the flex goes to the main board which is vaguely face shaped so you can diy something for that.
also what may be fun is adding a 5.8ghz video receiver to a tap, so you can pickup feeds from around the place and as its analog anyone can tune it, truly open source!
Thanks for reading and I hope to make my own tap soon after I've been thinking about it for the last idk 5 years? never knew there were others! but just ask if this needs any clarification or anyone is interested in the racing part.
I found a cheap beam splitter on banggood:
banggood are usually quite good and ive ordered much more expensive stuff from them so this should be fine. I just thought id put this here as I saw you guys had an issue with expensive beam splitters, (might have been prisms but idk enough about this yet to know the difference).
