Hurrah! I’m very pleased to announce the first ever successful opening of a Reverse Geocache™ Puzzle Box. (If you don’t know what a Reverse Geocache is, you should read this first.) The event occurred Saturday night, January 30th, in Austin, Texas, USA.
Alas, it wasn’t the famous box that opened – that one is still sitting sadly on a Parisian bookshelf, waiting patiently for its newlywed owners to transport it to their romantic island. No, the box that was solved is the black floral-patterned one from a brand new collection of prototypes I’ve recently constructed. These new models have features that improve on the original without damaging its charm or mystique.
The new designs sport a discreet USB connector that provides the emergency “back door” access – for those that know the secret password. As the owner, you can open and close the box to your heart’s content and program your own destinations. When your recipient finishes his/her puzzle box adventure, you lock up a new “treasure” and begin another!
I was privileged to be in attendance at the big event, and when that little internal motor whirred to announce the opening, the car erupted with cheers. The experience taught me something interesting. I learned that besides hobbyists, geocachers, romantics, puzzle collectors, and artsy geeks, another population thinks puzzle boxing is pretty fun – kids!
The claimants to the title are in fact children — our two and one of their school friends. Here’s what happened.
I sealed a $20 bill in the “Black Floral” and programmed it to open at P. Terry’s, a slightly chic burger joint not too far from our house – 1.71 miles, in fact, according to the blue display. I modified the greeting to read “Your/dinner/is in/the box!” – customizing messages is another thing the owner can do – and handed it without a word of explanation to my 11-year-old son.
Well, my kids know what to do with a puzzle box, and soon a van full of youngsters was motoring about town hunting for their supper, yours truly acting as silent chauffeur. As we drove, I discovered that young folks take a vastly different approach to solving this kind of puzzle. Most of my adult readers like drawing circles on maps and performing calculations vaguely suggestive of what we call trilateration, but kids seem to have little patience for pencils and compasses. They prefer to just drive, drive, drive – repeatedly pressing the button and changing course when the distances start increasing. This semi-random-walk technique can quickly get you stuck on a dead-end street in the “wrong” part of town, but I have to say it’s no less exciting than the scientific approach.
After a few faulty turns and considerable head scratching, they finally found their dinner. At one point in the adventure we actually stopped at a light immediately opposite P. Terry’s. I thought the gig was surely up, but even though the display read “Distance 163 feet” – just barely outside the 150 foot radius I had set – the kids still managed to fritter away 20 more hungry minutes navigating a parking lot half a mile further down William Cannon Drive.
Now that I’ve experienced the dual joys of building and delivering Reverse Geocache Puzzles, it’s very nice to actually get to play with them. Today my little nephew Nate was looking a bit forlorn, so I put a tiny toy in one of the small maple boxes and sent him on his own private mission. To boost his spirits I personalized his name into the greeting – “Hi Nate!/ Can you/open the/box..?”. He’s not yet eight, so I just sent him to a neighbor’s house about 600 feet away. When after a few minutes he came trotting back, Piglet style, “his” box open and treasure in hand, the smile on his face belied his happiness.
The Reverse Geocache continues to prove an interesting little puzzle with broad appeal. Whether it’s a romantic engagement-ring trek to the summit of the Matterhorn or a little kid’s 20-minute “adventure” down the street, solving one is a rich and joyful experience.

Amazing and Congrats!!
The refinements sound fantastic. I’m on the mail list and I CAN’T WAIT to see options for the final product.
I’m planning on using it for my anniversary in November but I have no clue where I’ll send my wife or what I’ll put in the box. I can’t afford a really nice piece of jewelry right now and short of something of that nature I can’t imagine anything worthy enough to go into the box! What a dilemma. LOL!
Keep up the good work!!

So after you’ve gotten the process down, what do the numbers crunch down to? More/same/less than the original? Very cool idea.
Virgul

As a senior in high school I would love to get one of these for my parents when I leave for college. How customizable is the code?
Mikal

Hi Stepshep–
Not sure what you mean by ‘numbers’. Can you clarify?
M
Mikal

Hi Virgul. Bravo for you. Most of the time it’s the parents who want to give their graduating senior a box. :)
The ones we are making are customizable in the sense that you can program your own destination and radius. In other words, you select the spot at which the box will open and the radius of the circle around that spot. So for example, if you want the box to open on the French island, you’ll choose a radius of, say, 2000 meters. But if you want it to open at the tree where you first kissed your girlfriend, well, then it might be more like 40 feet.
You can also customize the greeting: “Hi Mom and Dad!” for example.
Is that what you mean?

Hi Mikal,
I’d like to firstly thank you for your advise earlier regarding setting up the GPS unit switching rx/tx lines did the trick… I was able to completely rebuild my own geo-puzzle box using a RFID reader/card combo to act as a secondary key.
I’ve found using Google Maps to get lat/lon of certain places can yield an inaccuracy of +/- 150m. I’d very much like to reduce that to ~30m. However that’s a little difficult to do when I can’t always travel to the unlock site and take a reading. How have you gotten around this issue?
Cheers,
Peter.
Mikal

@Peter,
Wow, 150m? I’ve probably participated in ~50 Puzzle Box adventures and have never encountered an error of that magnitude. They’ve all been spot on. I wonder if it’s related somehow to the part of the world your adventure took place in?

What is the chance of ordering one of these boxes. I would love to give it as a gift for my brother. I think it would also think it would be fun to circulate here around the Geocaching community here in Maine.

@Robert,
Thanks for your interest. I have started building a few of these on commission and anticipate making an announcement shortly about making more for the general public. Stay tuned! :)

Mikal,
Just finished reading the latest chapter, facinating, many congratulations. Several years ago we sailed our sail boat round the Ile de Brehat. A magical place, and well choosen target.
I just wondered if you had considered giving the ‘giver’ of the box some feed back, maybe by encorporating a mobile phone modem to send a text message of where and when the button had been pressed, etc. Probably someone else has suggested this, and/or the battery power might not be big enough. But it would be interesting, maybe, for longer ‘projects’
best rgds Jim
Mikal

Jim, thanks for the interesting suggestions. I agree that it would be much fun to give the box the power to “tweet” its location along the way. I haven’t yet worked out a good solution how this might happen within the power constraints you allude to, but agree it’s worth investigating.
Meanwhile, the design I am currently sending people does record the steps along the way so that when and if the “solved” box does make it back in to the hands of the original owner, he/she can capture these into a computer. I am currently building some software that displays the journey on a Google map. Eventually I hope to allow owners to publish their adventures. It’s all great fun.
Thanks for the note.

What if you put solar cells on the box to keep the battery charge up? It has to be outside to be used anyway and I’m sure the Arduino could be smart enough to only let the batteries charge if there was sufficient voltage coming in from the cells… Then you could greatly increase your battery life and be able to tweet the location.
Love the concept!!

@Scott–
Yep, that would be really cool. And a hand-cranked power design would be interesting as well. Or a combination of the two…

Greetings Mikal,
This is a great project, and it sounds like it was a lot of fun for you and your friend. I have heard of it through geocaching, and since it is a “reverse geocache puzzle”, I am wondering if there is a version that is an official geocache?
Cheers,
~Bob

Bob–
I am always working through interesting variants of the basic idea. You could have a reverse geocache lead you to a “real” one, or– find a reverse geocache in a real one. There are a number of interesting permutations. Thanks for sharing.

Why not START a website and have these move around like the now defunct “moving Geocaches”?

I built one of these boxes and gave it to a friend. I put the open location right next to the hedge labyrinth at the Mortain Arboretum and she spent an hour and a half trying to find a spot where it would open before she figured out it wouldn’t open inside the garden. Lots of fun.

Jeff! Thanks for sharing. It sounds like a great story, and since I’m collecting great stories, why don’t you send me some more details… mikal at arduiniana.org? I love your crafty labyrinth idea. I had thought of making the “magic destination” a position somewhere in a lake, but the “sensitivity radius” large enough so that it touches one tiny piece of shoreline. There are a number of good ideas floating around, but yours is one of the best! :)

Mikal,
Sir, this is truly one amazing item. I’ve come across this many months ago and never gave it a good second thought. Now, with my grandchildren and I into going on Geocaching experiences, I had to revisit this. This would really make a great gift and adventure for them. Unfortunately I don’t have any mechanical skills to even begin to build one of these. How excited I was to read your current posts that you may build some units. I certainly would be interested in finding out the costs for one. A very unique and reusable idea !!

Hi Mikal,
I see lots of people are ready to purchase one of your reverse puzzle boxes, that includes me!
Being on the geeky side, I would settle for the plans and give it a shot to build myself. Being a woodworker, the box wouldn’t be the problem, it is the electronic that may cause an issue, however I would still be intrested in the detailed plans if they are for sell.
Thanks,
Kent

Mikal, nice to see your comments about getting farther with “production units”. The new features you mention are rather interesting, especially being able to see where the box ventured as the recipient tried to solve it. Have you thought of logging data in the format of a KML file for Google Eaarth? I recently did that with the Parallax Propeller and because the KML file format is so easy to play with, you can make the “logs” pretty slick
I am working on similar GPS based projects, however, the second version of my propeller based box strays a bit from the original idea. (my original one still gets lots of views on the Parallax completed projects forum.)
Good luck with the continued success!

Awesome Idea. Once i heard about this my mind began to envision alternate uses. I want to make one that only opens at a specific time and location.then load the cache with the party favors, for example: a cache that only opens at the best place to view a meteor shower or eclipse, and include binoculars, etc..ooh or about build a camera into the box to capture the moment when the box is opened. I love it..now to make my own..

Hi Mikal
I love this invention, i’d love to give one to my girlfriend someday. From the number of posts on here i imagine you have quite a backlog of request buyt i’d be very grateful if i could be added to the waiting list for a finished box. I’m also going to attempt to make my own in the meantime, although i’m not the most technically minded person so it might take a while lol. It would really help if you would email me the designs as i see some others have requested.
Thanks a lot in anticipation
Gregg.

Hey Mikal,
Wow, this has to be one of the greatest inventions ever!
I have a few suggestions for you. Maybe have a plug on the back that plugs into the mains to charge up the batteries, it would be a major pain in the backside if the batteries ran out. I’m not sure if you already have it, but some sort of failsafe that you also plug into the back, like a plug that has a some sort of pulsing circuit, and if the box reads the pulses, it opens.
I know that you must have a backlog of requests for the schematics and code for this, but even for a small cost you could sell them to people who want to make it themselves. I am getting better with my electronics but not enough to make something of this magnitude!
