I've been given the task of preparing a rig for a very harsh environment. I have to get 8 trackspots and 6 AF1000s to survive a week in a sandstorm. The AF1000s are weatherized, so i'm going to do very little about them. The trackspots, on the other hand, could be problematic. So far, I've come up with sticking car air filters on the front vent and gaffer taping all possible entry point of sand. I have not yet figured out how to seal the intake port. I will also be given a budget to replace the pan and tilt motors as they clog and die. But I really don't want to be replacing interior parts except lamps and I don't want to be cleaning the color wheels on a daily basis. Difficulty: the sand is a heavy alkaline and could be corrosive. It is also a very fine particle, similar to talcum powder. Bonus: Technobeams? Super Duper Bonus: Emulators. Finally, I'll be taking backup controllers, but really don't want to lose any vintage HES LCD controllers, as they're getting difficult to acquire. Any thoughts on protecting these?
