There is so much to report that I hardly know where to begin. The biggest news is that I have begun actively delivering commissions! If you want to finally get your hands on a second-generation programmable Reverse Geocache™ puzzle, keep reading.
PCBs
This winter I began developing a new specialized PCB (“printed circuit board”) that greatly improves reliability and shortens build time. What this means is that it no longer takes me several days to create a new box, so those of you who were hoping to get one soon might actually be able to!
The new PCB has enabled me to build a number of samples. Large, small, ornate or restrained, they are all fun to build, and each has its own unique charm. Check out these samples:
MAKE Magazine article
In March I was contracted by MAKE to write a feature-length article on the Reverse Geocache™. It was a surprising pleasure to write down my experiences with puzzle boxes and to recreate amazing tale of the very first one (which still isn’t open, by the way…) Look for the article to appear in print in the Fall (October 26th) issue! (Edit: it actually came out in January, 2011.) Here’s one of the photos I took. That’s my nephew Nate solving a mini-quest using one of the “Elegant Black” boxes.
Travel Advisory
During Spring Break I took one of my “Engagement Ring” boxes to New York to show at the Arduino developers’ conference. On the trip I learned what (and what not) to do with a box at airport security. With the box stashed in my carry-on luggage, I jammed up the Portland (ME) security line for about five minutes and was subjected to some rather serious grilling. Once things quieted down, the security chief confided sternly that I was lucky my box was empty. Had any “mass” been detected alongside all those wires and electronic components, he warned, it would have “shut the place down”!
Lessons learned:
1. It’s probably not a good idea to send your friends on a quest that requires air travel. Don’t put them into the position of having to bring a suspicious box they can’t open onto an airplane.
2. If you do travel by air with a puzzle box, leave it unlocked in your checked luggage and remove the batteries. (This seems to work for me.)
3. (From the security chief) If you have to carry one through security, first remove any contents and the batteries, place it open on the conveyor belt, and alert the security officials beforehand.
Puzzle Box Movie?
While in New York I had a telephone meeting with a couple of guys who work at a Hollywood production company. They are actively developing a studio pitch for an adventure film based on a mysterious puzzle box that appears in the lead character’s mail. Wouldn’t it be fun if such a movie gets made?!
Mini-quests are fun
Towards the end of March I gave a short talk about my boxes to a crowd at SXSW (South by Southwest) and afterwards sent members of the audience on little mini-adventures to nearby bars and restaurants. One of the great (and frankly surprising) things I’ve learned is that while the first box was designed for a long, romantic adventure, it also works great for tiny ‘treks’ to nearby destinations with modest “treasures”. A short quest to a bookstore or restaurant is easy to put together and great fun for all ages.
Interview with geocaching.com
In April a video crew from Groundspeak (geocaching.com) flew down to Austin to interview Richard Garriott and me. A new website they’re building in honor of the 10th anniversary of the first geocache (5/3/00) will include about 20 short videos detailing great geocaching stories, of which mine is apparently one! (Garriott is most famous for having paid $25 million to ride the Space Shuttle in 2008, and while aloft hid a geocache on the Space Station.)
After we wrapped up our interview I surprised the crew with a fully armed puzzle box filled with candies and a gift certificate to a Mexican restaurant. They had a blast using the box’s guidance system to lead them to the restaurant, and of course, being plenty hungry after their lenghty search, were pleasantly surprised to discover its contents. If you want to see the route they took to get there, here’s the Google map generated by the box. Eventually, I hope to make it possible to publish any adventure this way.
The first commission
The last bit of news is that in May I mailed the very first commercial puzzle box to Seattle, fulfilling a commission from Jeremy Irish, the president of Groundspeak. I was actually a little sad to see it go. It was one of my pretty “Engagement Ring” model boxes, designed to comfortably hold a small payload in a felt-lined interior.
Commissioning a box
As I mentioned, I have started building commissioned boxes. If you would like one, I will build you either an “Engagement Ring” model for USD $699, or the “Painted Indian” model for USD $549 plus actual shipping. The “ring” boxes are handmade by my talented artist friend Andy Myers (see his website). The “Painted Indians” are funky modified World Market boxes.
Here’s what you’ll get:
- A handmade Reverse Geocache (requires 2 AA alkaline batteries)
- A one-year warranty
- (Free) Windows configuration software to program new destinations, greetings, number of attempts, and sensitivity radius.
Each box has its own serial number and password, which you need in order to reprogram it. There is already a backlog, so please be patient. I’ll mostly fill requests in the order received, although I know some of you are hoping for boxes for particular events. When you send your request, please send the date you need it (if any) and I’ll try to work that into the schedule.
I appreciate any feedback you may have. Thanks for being part of this fascinating community; I’ve received such interesting emails and letters. I particularly look forward to collecting more great stories of your own quests.

Looking good. I like the small box the best. I would very much like to see how you made that locking mechanism. I need something more reliable for my box then the clasps I was using. Do you have any trouble getting a GPS signal with the 406A sideways? I thought it had to remain upright.
Mikal

Jeff, the lock is a simple cabinet latch epoxy glued to the shaft of the servo. I was worried about the servo orientation on that box, but it seems to work fine. My recent designs, though, all have the GPS module placed flat against the box wall.

Very cool! I’m making my own version of your puzzle box and I had a question about the servo. On initial power up, does your servo move a little, about 45 degrees? Mine will move once power is applied, but once the code starts processing, it will move back to its specified position.

Hello,
I’ve been following your Reverse Geocache saga on and off for some time now.
Is it possible to get a kit? Say, the major electronics, a parts list, and a build suggestion? I would like to put together a box of my own.
Thanks in advance.

Mark, my servos “chirrup” a little bit at startup as well. I’d be surprised if it was 45 degrees, but a little, yes.

The servo issue is simple. Instead of wiring the servo power to the +5 line move it to a digital pin and only turn it on when you intend to move it.

The whole concept of your puzzle boxes is beyond awesome. I really like Alan’s suggestion about selling a kit so folks could build their own. If you ever make that a reality, I would be interested! I would love to put together a box of my own and make it truly unique.

Hi,great idea, and good luck! I’ve put together a gps puzzle like this, but with an analog user interface to make it more of a complete puzzle challenge. http://electricgeocaching.blogspot.com/2010/08/gps-puzzle-box.html
I ended up tinkering with the TinyGPS library so that I could specify a maximum DOP. Dont know why but I was often getting high DOPs making the readings too inacurate for nore precise games.

Jen, we are working on figuring out how to make a kit. It’s a time consuming process — we want it to be good! Stay tuned.

Reading this has really made my day. I’ve always been interested in geocaching, but this is several levels up from that. I wish I could afford one or know how to recreate it myself. One question though, you said you didn’t want it to become mass-produced and lose the sentimental feel to it, but I see many people have worked out out to make one themselves. Do you not worry about someone deciding to pitch the idea, or do you have full rights to it?
Mikal

Oh hey, thanks, Maria.
What we’re trying to do is encourage people to talk about the idea of the Reverse Geocache ™ and experiment with building their own devices. As you point out, there are a number of people who have been so captivated by the idea that they have created their own variations on the idea, some more successfully than others. This is nothing but good.
On the commercial side, we continue to work to refine and improve our designs and reduce costs. My goal is to make it possible to any group or person who really wants to experience the magic of a Reverse Geocache quest to do so with one of our boxes. And to answer your question, yes, we have filed a patent application and are trademarking the term “Reverse Geocache”.
Thanks for the kind words.

Hi Mike! I love your boxes and just finished reading the stories! I haven’t read all the comments, but I was wondering if there are plans for a kit or at least release of the code and schematics to build a custom box of our own! I love Geocaching and would really like to actually hand build this. If none of that is or will be available, can you point me towards the best place to learn the coding I would need and give me a few pointers?
Thanks,
Brian

Hi Brian.
I do hope someday soon to have a snippet of RG sample code to share. But I have to say that there are a number of people who started out by asking for schematics and code who went on to craft their own device anyway. Many of these report that an already rich project became richer and deeply satisfying by virtue of having been built and “invented” on their own.
Start off at the “mothership”: http://arduino.cc. Check out tutorials also on ladyada’s great site: http://www.ladyada.net/learn/arduino/.
Keep in touch!

This is such an awesome project. I keep coming back to check for updates once a month.
In regards to others making their own, has anyone seen the one that a guy did with a Parallax Propeller? It’s a really nice job also.

Is there any chance of there being a DIY kit for this? A PCB and parts or perhaps just the PCB? I know in one post you said you dont want to see plastic copies out there but I want to make one of these from ultra high molecular weight polyethylene. I think it would make a cool looking box.

I noticed on the YouTube video that you used a piston actuator rather than a servo to lock the box.
I have struggled with the originally recommended servo but it seems to have a mind of its own regarding where it should turn to. I already only power it if I am ready to control it and store the last controlled position in EEPROM.
A linear actuator, especially if we only have to send an IN or OUT signal to it would make life a lot simpler.
Can you give the make and model of the linear servo you used in the YouTube video.
Mikal
13 years ago
Lew,
All of my designs (so far) have used servo motors. What you probably saw in the video was a Hitec HS-311 servo attached to a hand-made piston of sorts. The piston is just a dowel rod inserted into a sleeve I made by drilling a hole through a block of wood. If you fasten the servo to the end of the dowel with a paperclip or other clasp, you can get that linear motion you describe.
Programming is not much harder than sending a IN or OUT signal. You have to calculate where to position the servo for “IN” or “OUT” and then just write code like
servo.write(45); // open latch
servo.write(135); // close latch
One other thing to note is that the revised Servo library which appeared with Arduino 16+ is incompatible with NewSoftSerial. I get around this problem rather easily — I just use the old Servo library. If your servo “has a mind of its own”, you might try this technique.
Mikal

Thanks for the reply. Since I have been using Arduino version 19 and the latest NewSoftSerial, it sounds like the incompatibility you mentioned has been causing my problems. I wish I had known that before.
On my project, I could get my code to move the servo like I wanted maybe 50% of the time but it frequently went past the point I “controlled it to”. I’ll try the older servo library.
After weeks of struggling with the servo code, the thought of an actuator with just an IN or OUT command sounded like something I would have given my arm for.
Thanks for the idea of the box. It took me three months to build mine. This time was spent venturing into areas of hardware and software and woodworking that had been completely unfamiliar to me.
I had just started to learn about the Arduino when I came across your description of the Puzzle Box. My previous simple activity of just lighting an LED immediately got shelved and I jumped into the deep end with this project.
Although at times I would have wanted a more detailed description about how to make the parts work together or the software to work, I had lots of fun stumbling through it all. The only tragedy was one ATMega328 that got trashed.

This is such a great idea, its a shame I found it so many years after you created it. I suppose you aren’t making new boxes anymore? I went to the website and it says “out of stock”. I would really love the ring box set up!
