At this year’s HOPE conference, German competitive lockpicker and security researcher [Ray] gave a talk about escaping high security handcuffs that are probably being used by your local police and other LEOs. He’s doing this with 3D printed and laser cut keys because, you know, security through obscurity never works.
Two years ago, [Ray] gave a talk at HOPE on 3D printing Dutch handcuff keys (you can listen to his conference as an .MP3 here). This time around, [Ray] copied the keys of Bonowi and Chubb handcuffs, very popular brands for American police. After obtaining a key from each of the two brands, [Ray] broke out the calipers and micrometer and designed his own versions that can be printed on a RepRap or Makerbot, or just laser cut from a piece of plastic; the perfect material for sneaking one through a metal detector.
The .DXF and .STL files for the handcuff keys will be available on Thingiverse shortly. We’d suggest watching
this Thingiverse account (nevermind), as they have the files for [Ray]’s earlier Dutch handcuff key.
Opening really old lock boxes
[Barry Wels] is a locksmith. One day, he got a call from a museum that had a few 17th century strong boxes that needed to be opened. After a little probing with an endoscope, he decided they could be picked with a little bit of spring steel. So, what’s in the box? [Barry] is going to send in an update in a month or two.
An awesome Geordi La Forge VISOR. But don’t take my word for it.
[DrewSmith007] made a replica of Geordi’s VISOR from Star Trek: The Next Generation. Bonus: it’s autographed by Levar Burton.
Free mirrors for your laser cutter
If you have a laser cutter, your mirrors will get damaged, and they’re very expensive to replace. [Phil] sent in a neat tip: make your own mirrors from hard drive platters.
A proper M.U.L.E. remake
Combine Settlers of Catan with M.U.L.E.. That’s what this Kickstarter is trying to do, and it sounds freakin’ awesome.
This game is so cool
A few months ago, I mapped the surface of a video game moon. Since then, Kerbal Space Program had a huge update with a brand new moon. Over on Reddit, [InsanityCore] started mapping this new moon, so I rendered it. Go give [InsanityCore] some karma. He did all the hard work.
This is why digital picture frames were invented
[Petros] sent in this video of his visualization of Van Gogh’s Starry Night. He did this with openFrameworks and also made a version that reacts to sound. Is anyone else reminded of that one scene in Vincent and the Doctor?
A boat’s a boat, but a mystery box can be anything
[Rick] wanted to build a lock pick training station for the Eugene Maker Space, but he needed a way to make it interesting. What could be better than a mystery box? When you pick the deadbolt, open the box up and you’ll get a prize. Just make sure you put something of yours in the box for the next person.
3D printer prints its own case
Because the 3d printer community isn’t segmented enough, [Sublime] decided to design a new one. Here’s where it gets cool: the Tantillus can print its own case, and can ‘daisy chain’ to another Tantillus so only one set of electronics are needed. Interesting ideas afoot.
A diamond says I love you, but a duct tape rose says I’ll fix that for you
Valentine’s Day is coming up, so if you haven’t already made dinner reservations, you’re probably up the creek. How about making a duct tape rose for that special person in your life. Bonus: a dozen costs $3, and they won’t die in a week.
Using keypads over serial or SPI
[Leniwiec] sent in a tutorial on connecting keypads to a microcontroller with a serial or SPI interface. If you want to build a calculator, this is your chance. We’d use this for an Apollo Guidance Computer, though.
The guys from Bloomington’s Fraternal Order of Lock Sport (FOOLS) sure know how to throw a party! At this year’s DerbyCon event down in Louisville, the group put on an awesome event that combined lockpicking and drinking – what could be better?
The Rumble Challenge is lock picking game where six people compete head to head for the best time. Whenever a competitor masters his lock, the competition is paused so that each player has a chance to take a shot from their air-powered shot dispensing machine. Once everyone has imbibed, the next round starts with the competitors picking up where they left off, in an effort to be the next to successfully open his lock.
The game is controlled by an Arduino, which both times the competition and senses when the locks have been opened. The Arduino relays this data to a computer, which uses a projector to display the contestant’s scores on a big screen. As an added bonus, FOOLS member [dosman] added loud rumble motors to the locking mechanisms in order to throw competitors off their game.
The contest sounds like a ton of fun – we’re bummed that we missed it. If you want to see how the game was put together, check out [dosman’s] build log over at the Bloominglabs wiki.
Hackers at the “RaumZeitLabor” hackerspace in Mannheim Germany have noticed that the locking mechanism on the thinkpad mini dock is extremely easy to circumvent. Sold as an additional layer of security, the mechanism itself is not really secured in any way. The button that actuates it is locked by a key, but the latch isn’t secured and can be accessed via a vent on the side. They are using a lockpicking tool in the video, but they say that even a long paperclip would suffice.
We know that no security device is perfect, and if someone really really wants it, they’ll take it, but this seems a bit too easy. Maybe the next version will have a little plastic wall protecting the latch from being actuated manually. Hopefully if security is your main concern you are using something a little more robust that a dock-lock.

This month’s Wired magazine has an extensive profile of [Marc Weber Tobias]. He’s a professional lock picker that delights in coming up with new techniques for taking on high security locks. In recent years, he’s run afoul of the US’s premier high security lock manufacturer, Medeco, by publishing Open in Thirty Seconds with [Tobias Bluzmanis]. Medeco still denies that this is even possible. Wired decided to to test the team by purchasing six new cylinders and timing them. Each one was open in under nine minutes. You can see a video of this on Wired’s site.
Last fall we covered a decoding attack against Medeco locks by [Jon King].
Sometimes describing how a lock actually works can be the hardest part of teaching someone about lockpicking. [Mike Gee] has designed an acrylic lock that may just be the ticket for these situations. All of the pieces are cut from clear acrylic. As you insert the key, you can see it raise the four pins up to the shear line. He says that it will definitely take some tweaking as you assemble it to get it to function smoothly. Embedded below is a video of the lock in use. You can find plans on Thingiverse.
