Dear Mr. Hart,

When I read about your reverse geocaching puzzle I was amazed. Not only by the articles on it and you by many websites that I follow, but by the amount of thought you put into the project. I would very much like to continue a conversation about the project and the use I may have for it in my future plans. If you would be willing to discuss this further, please email me at either timothy.j.engler08@business.colostate.edu or at noodlengler@hotmail.com. Thank you for your time and consideration. Good luck with any future projects!

Sincerely,

Tim Engler

Some GPS modules seem to have the option of a wire antenna, typically just a couple of inches, I think. It seems to me that this would give a nicer appearance especially if the antenna were glued into a small slot routed into the box at a corner or something. On the original box with the elephant I suppose it could go in the carved depression above or below the elephant.

Very intriguing project and story! Thank you for the great libraries, as well.

recently i started trying to make my own. i have a gps module and am able to get a signal and my coordinates. i was wondering what calculation you used to determine the distance. my basic code is from this website http://www.arduino.cc/playground/Tutorials/GPS which i have modified to store the lat and lon as floats. any help would be greatly appreciated.

Mikal,
Could you possibly email me some further details for the construction of the reverse geocache please. I want to construct one for use in expedition and orienteering exercises with a cadet unit i work with.
Thanks
Ian

Mikal
I would love to build one of these as well. Could you please email me some info on what to do with the parts you have listed on The Reverse Geocache™ Puzzle Box page? I would like to know just how complicated this is before I commit to buying the hardware.

Thanks

Is there anywhere/one in Australia making these boxes that we could purchase

Hi Mikal I plan on building one of your puzzle boxes as a gift for my friends wedding. I would very much like to buy one of your custom shields

Mikal,

Thanks for the several great libraries. I made some mods to TinyGPS to enable fix notifications.

I needed this for consistant GPS time syncing.

The mods are published here:

Thanks again,

WOW, your reverse geocache puzzle is such a dazzling idea, AND you had the brains to build it. I think your mind is the biggest “gem” of this page!!!!

Thanks for the great work you develop, I was wondering if you have not thinking about developing the library TinyGPS for a Chipkit, would appreciate it fully.

Thank you.
