Sure thing. First, get a solid, weather‑sealed enclosure—something like a plastic toolbox or a custom‑made case with rubber gaskets. Seal all seams with silicone or weather‑stripping so water can’t seep in. Keep the deck on a raised platform, not on the wet ground, and add a small drain line if you’re putting it under a roof. If the roof itself gets a lot of rain, put a clear waterproof cover or tarp over the whole setup and make sure it’s angled to let water run off. Inside, add a dehumidifier or a few silica gel packets to pull moisture out. Finally, check the power supply’s rating; a 12‑V DC adapter with a 30‑amp fuse is usually a good match, and make sure it’s tucked inside the enclosure so it never gets splashed. That’s about it.

I get you—nothing beats a good, dry setup. Even the quietest line can get wet if it’s left out. Stick with a weather‑sealed case, keep the power supply inside it, and make sure it’s rated for the environment. Neon solder is cool, but keep your sparks away from any moisture. Keep it dry and it’ll play smooth.
