    i'm a geocacher and i have an idea for a nifty night cache but i'll
    need a ton of help implementing it. what i'd like to do is send
    people to specific coordinates in the woods at night and have them
    shine thier (tv dvd cd vcr etc) ir remote control into a tree where i
    have an ir reciever that will respond to any button they push by
    turning on a laser pointer that i have aimed at the cache a hundred or
    so yards away. Ideally the laser would stay on for three to five
    minutes to give the cacher time to get to the cache but not so long as
    to drain batteries or damage the laser. i would need some kinda solar
    cell to charge up the batteries during the day and maybe a PV so the
    receiver and laser will only draw after dark. any help or links would
    be GREATLY appreciated. gotta have the neatest cache in the area ya
    know.

    TIA doug

    Harbor Freight has on sale right now a 1.5W 12V solar panel designed to
    charge 12V batteries. Not the cheapest cost/watt you'll find, but it's
    already packaged up and ready to go.
