That's a really interesting design... kinda wish I would have seen it over the summer. I had need for outdoor wireless
DMX with nothing close to a reasonable budget for it, so I ended up buying a kit of the
XLR dongle-style transmitter and receivers as an experiment. I took the guts out and put them into 3D printed cases (including the board from the
wall-wart style
power supplies). I also added a
button on the bottom of the case for
channel selection. Since these were bound for trees and such, the eye-hook was my idea for easy hanging.
The event ended up getting cancelled at the last minute, so they were only outside for a few weeks instead of the expected 2+ months, but they held up well to a couple good rain showers as well as spray from irrigation. I had some weird behavior with one specific transmitter, but once I
identified that one as the culprit, I had good performance even with about 200' to the farthest receiver. I don't know how much I would trust them for anything important in a more complex RF environment, but they are kind of surprisingly good for the price.
Not sure why I felt the need to take a picture before soldering that last
wire, but this is what I had handy on my phone...
