Hey everybody.
I am working on a metal sign right now for my company and it will be set off from a backing board. I would love to throw some LED light strips behind the metal to shine on the backing board (bright green). Anyway, I was wondering if anyone could help me on the control unit.
The sign will only need to operate starting at dusk and for a few hours thereafter. I would like to run it off of a 12volt lead acid battery with a solar charger. Does anyone have any simple, efficient designs already in existence that I could use?
I think a simple PIC and a light sensor circuit with some mosfets will work fine for the operation of the LED's. The thing I'm mainly stumped on is the charging mechanism.
thanks much
