Do You Make things, like DIY projects for your photography? I was going to start a thread but this one is here?
I've seen some DIY stuff that does look professional. A friend of mine made a grid out of plastic drainage spouting pieces and blac straw. He sprayed the whole thing black and it looks like something from Honl.
Also, people like Gary Fong and David Honl are selling products that I'd bet on them originally starting off as DIY gear that they thought was good enough to refine and sell.
Fongs diffuser from the moment I saw it, is a fruit salad container or some whipped cream packaging. Yes, nice idea and it works.
OK what I wanted to do was start posting some of mine. I'm not selling anything and I make no claim that anything is more than modified "something else" in an effort to have some fun and make some photos. I can't say I have a favorite, but this one was useful and has been loads of fun, and I still carry it in the car. (which is a Minivan, or it wouldn't fit)
I'm on the left, taking the photo of the
camera on a stick 
which is the right half. In this case, it just happened to be a GoPro but there's a threaded mount on the top and I have put a DSLR with a Tele up there, over a catch fence at the races.
It's an ultimate selfie stick? No not really, it's a 40 foot hotstick, (a telescoping fiberglass pole) that I found in a dumpster. Free is good. Slightly less that 40 feet because the last section was broken off. I filled the hole with a wooden plug, which I epoxied in and then drilled and threaded a standard tripod 1/4-20, I have added a ball at times or just straight camera on the top.
No drones for me, I have the 35 foot, big yellow stick!
Still playing, not serious, this was one of the first test images. But you can see how the elevation is interesting. It is also a stitch image, which makes the 90 degree corner look like something else.
And finally, an IMSA race start, with the camera on the stick, set for intervals, as photographers aren't allowed to stand at this point of the track.
