Mystery Box Out Of Lego

February 23, 2011 by Kevin Dady 8 Comments

[Todd] recently completed completed his biggest LEGO project, and its pretty wild. The Mystery Box is an 8 compartment LEGO brick puzzle box, covered in a psychedelic pattern of interconnecting question marks.

The question mark pattern was inspired by a few things, the book called “The Curious Incident of the Dog in the Nighttime” contained an illustration that looked sort of like a M.C. Escher painting, which with some looking around brought up tessellation. With the look in mind [Todd] sat down with a paint program, drew out a grid, and started flood filling blocks until the pattern was perfect.

In puzzle box tradition, to gain access to the contents you must remove each compartment in the specific mystery order, and to accomplish this was no easy task. Lego Digital Designer was used to prototype everything on the box and then once happy, [Todd] broke the model down for a parts count.

Nearly 8,000 parts, 35 brick orders, and some long waits, the box was finally completed and its definetly worth a look. If you’re not that extreme, they also make cool electronics enclosures.

Reverse Geocache Features UI And Is Reprogrammable

January 9, 2011 by Mike Szczys 7 Comments

Here is yet another offering in the Reverse Geocache puzzle arena. We’ve been getting a lot of tips about these projects but this one in particular stuck out from the others. [Mure] packed in a bunch of features, starting with the LCD screen seen above. You can just make out the single red button near the bottom of the image which is used to traverse the menu. The octagonal box has an octagonal PCB inside that includes a USB connector. As you can see in the video after the break, this can be used for charging the batteries, and communicating with the internals. An accompanying program is used to generate puzzle data, which can then be programmed via that USB connection to set a new puzzle location. This functionality certainly protects against accidental lock-outs which were a problem with the last puzzle we looked in on.

Great Interactive LED Puzzle

July 2, 2010 by Mike Szczys 13 Comments

The GLIP project takes the delight of blinking LEDs and combines it with the ingenuity of modular communications. This takes the Puzzlemation concept a few steps further. In that project the modules were programmed through a base station and could be removed and used as a puzzle from there. The GLIP project uses a master block that you can see tethered in the photo. But the blocks communicate with each other via an infrared protocol. This way they can be continuously updated as they are place next to each other. Each module includes an STM32F105 ARM Cortex-M3 processor, quite a punch for the little blocks. Take a look at what they can do after the break.

Reverse GeoCache Puzzle Gets Downsized

June 20, 2010 by Mike Szczys 17 Comments

[Markus] built his own reverse geocache puzzle box but on a smaller scale than the original. His is based around a PIC 18F2520 and powered by two AAA batteries. The user interface includes one button, a 16×2 character LCD, and a piezo speaker. The box unlocks itself when the GPS module inside detects the proper location on the globe. There is also a secret code that can be tapped on the button to unlock the box prematurely, and another to show the locations in which the user attempted to open the box. This build doesn’t leave much room for a payload, but [Markus] did a great job designing the board and making the components fit as efficiently as possible.

$30,000?

Is it art or is it a puzzle? Well, it functions as a game but it’s certainly a work of art and priced accordingly. The Superplexus was featured in Make Mazine and Hammacher Schlemmer sells it for thirty grand (you can’t just click to add it to your cart though). Think of the work that went into developing this!

Rollable Display Update

[SeBsZ] continues work on his rollable display matrix. He’s got twenty five controller boards now and has them working as a matrix. We originally covered this in January but now it’s much easier to see how this can be made portable by mounting it on fabric or canvas. Check out the demo video if your interested.

Security testing suite

BackTrack 4 final has been released. If you didn’t like it when it was rough around the edges, you should give it another try. This lean and mean Linux ditro is made for security testing and is approachable for noob and pro alike. [Thanks Steve]

Power on the go

[Csae] uses this portable power center to fire up some studio strobes outside. It consists of a case, an uninterruptible power supply, and a couple of extension cords all hacked together into one. At first you might think this is a bit ghetto but it’s portable and it does what is intended.

Happy Valentine’s Day

Giving this LED-heart adorned shirt as a gift is sure to make your Valentine head for the hills. This project’s a few year’s old, but gawdy T-shirts never go out of style, right?

Buzzle: A Morse Code Puzzle Box

January 21, 2010 by Caleb Kraft 11 Comments

[lucasfragomeni] built the Buzzle after being inspired by the reverse geocache puzzle. The Buzzle was built as a gift to a friend. It’s a tricky gift too. His friend can’t open it until he decodes the words being displayed in morse code via an LED. A word is chosen at random, so you would have to decode it each time you want to open the box. That’s a pretty neat security feature. Sure it’s not the most secure, but it would keep casual peepers out. Unfortunately, the box was empty when his friend received it.

Laser-cut Puzzle Box

January 3, 2010 by Mike Szczys 12 Comments

One of our fondest memories from the 1980’s is watching Magnum P.I. on television. Higgins, Magnum’s employer, had a puzzle box that Magnum could never figure out how to open. Now you can laser cut a puzzle box for yourself and recreate some scenes from television’s glory days.

The design for the box pictured above is not new. The plans for the Cubey 2 project have been around for a while but relied on your mad-woodworking-skills to turn out the pieces. Since we’re not great with a chisel we were happy to see vector graphic and encapsulated postscript files to robotically aid in production. Once the puzzle parts have been assembled a facade is adhered onto each side to hide the pieces. This means you can go for Higgins’ traditional puzzle-box look or sport the hellraiser.
