So there is a large parking lot across the street from my display. I have a donation box setup over there, and I want to run some 12 lights so people can see it. Since there is no way to get power over there, I'm going to use a car battery or a jump pack. Then use an $8 DMX module cycling through test mode run about 1 meter of RGB strip. I'll probably have to charge the battery every other day. Does any body know of a 12 volt timer that could work in a setup like this? I don't need it to run all day and night. Just during show times to conserve the battery. Has anyone tried using a simple AC timer on 12 volts? I didn't know if it would slow the clock in the timer, or if it would even work at all.
