Wooden Gift box (GPS and Date)

this may have been done before...
I want to make a wooden box that can only be opened on a certain date (may be over a year away) and at a certain GPS location. my plan is to use a GPS module for date and gps. not sure how to make the whole thing light on power consumption for this length of time. Everything I have made to date has had the ability to plug in. Given the advances in batteries, should i use a Lipo for this aplication? it will sit on a shelf for a long period of time. What are some methods to not consume lots of juice. can i put the propeller "to sleep" and wake periodically to check the date?
Who has some ideas on the matter?

Thank you.

    It doesn't need to be on all the time, does it? User turns it on, checks to see if it's the right day (or after), then turns it off if not.

    Phil,
    It dawned on me that all i would need to do is have a momentary button. once pressed, it would latch until program is complete and then turn back off.

    you are correct. this will work well

    What you are talking about is commonly referred to as a Reverse Geocache Box and I made a Propeller based one 6 years ago. I put a lot of work in the thread for it because it came out so well (not always common with my projects, lol). Check out this thread:

    It is currently sitting on one of my wife's shelves so if you have any questions, I can still fire it up.

    I still have "V2" about 80% done. It is a scavenger hunt box the gives you step by step clues to route you to several locations that are loaded off of SD so no programming necessary. I was going to sell a kit for it and I even have 300 enclosures already, but it has been sidelined several times over the last 2 years, so is still sitting......

    Just FYI, I noticed that the forum migration and OBEX updates have wreaked havoc on the links in my Reverse GeoCache thread, so I will look at fixing that soon and may end up moving all the content to standard HTML on my own site.
