Not saber related, but I thought you folks might be interested. Those of you that are with me on Facebook have probably seen them.
Our local drive-in theater closed down in 2019. I managed to connect with the owners and buy up a bunch of the old speakers and junction boxes. I have been going through the process of restoring them, and making tabletop drive-in speaker stands with them. I put a Bluetooth receiver in them, and a white LED that shines through the downlight hole. They operate on 12V, so you can run them with a wall adaptor, or from your car's accessory plug. I have built a few full height ones as well. I'm working on a set for myself that will have an FM receiver as well, so I can take it to the drive-in that is still running in a nearby city, and stand it next to the car and listen to the movie through it.
Here are a few that I have made.
