The Reverse Geocache™ Puzzle

This is absolutely fantastic! What a beautiful and thoughtful present. I’m sure it was well received. Thanks for the nice writeup, too – reading it now..

This is an *amazing* project. To repeat Nathan, it’s incredibly thoughtful and awesome. That would be such an incredible gift. Awesome simple design, too.

Very awesome writeup too!

Have they opened it yet? Or are you just hoping they won’t find this page? :P I’m curious how they ended up determining the location, and how many tries it took!

Do you have a diagram for the wiring of the shield?

I think this would be an awesome way to propose to my gf.

Only one question. How do I get one?

Hey I read about your “Reverse Geocache Puzzle” and was completely amazed. That was a pretty amazing box. Is there any way I could email you and ask a few questions on some specifics on the codeing and how you put it all together. I would like to try and make one and was wondering if you could help in any way. Thanks for the post, completely amazing.

Found your description through one Jeremy’s tweet (- the Jeremy from Geocaching.com-)

Amazingly cool idea. I guess you’ll find a lot of hits the next time from Geocachers around the world.
Thanks for sharing your idea and story with us.

That’s awesome. I want to buy one!

Hi Mikal,

It’s great to see how your project turned out after seeing your work in progress at the ActLab. Awesome! And wow with the press! Congrats.

Absolutely fascinating! Is there any chance you will be willing to make the schematic and code available so we can make one for ourselves?
Thanks, Jim

I would like to make one for myself.. where do i get the code and schema?

I admire the ingenuity: human, personal, intellectual, and mechanical. I admire those who wish to make such a box themselves, which I shall never do. I would very seriously like to commission several of these boxes for my use as gifts. Mikal Hart, I would prefer to buy them from you. If you are not inclined to make these (it may be tedious, for all I know) may I solicit such construction from others, for a price? It’s one thing to make such a box oneself. It is another to solicit their manufacture, and I don’t want to intrude on your property. Thanks.

Hi Mikal ! Congratulations for this amazing project !
I am willing to make one for myself. I have already all the hardware and libraries.
However it would be very helpful to have the code and schema, is there any chance that I can get it ?
Thanks a lot, Carlos

Mikal, I am blown away by this! Like Carlos, I have also gone and purchased all of the components to make my own for some loved ones. And like Carlos, I am also interested in the code and schema is available. Are you planning on “open sourcing” the box?
In any case, thank you for the inspiration and for the information and libraries that you have provided already! -thrashor

Hi Mikal !
I just wanted to tell you that yesterday I finished my box following your guidelines and I was using it to give some ‘tricky’ Christmas presents.
Thank you very much for sharing your idea. I have head lots of fun and I have learned a lot about Arduino and this interesting technology.
And as I read somewhere thanks also for NOT share all the details of the project, it is much more interesting and funny to it work after doing some research and development.
Thanks again !!
