While it’s often thought of as a criminal activity, there’s actually a vibrant hobby community surrounding the art of lock picking. In the same way that white hat hackers try to break into information systems to learn the ways that they can be made stronger, so do those in the locksport arena try to assess the weaknesses of various locks. For the amateur, it can be exciting (and a little unnerving) to experience the ease at which a deadbolt can be picked, and if your concern is great enough, you can go a little farther and modify your locks to make them harder to defeat.
The lock in question was sent to [bosnianbill] by [Rallock67] with a device that [Rallock67] had installed using common tools. Known as a Murphy Ball, a larger-than-normal spring was inserted into one of the pins and held in place by a ball bearing. This makes the lock almost completely immune to bumping, and also made it much more difficult for [bosnianbill], an accomplished and skilled locksmith, to pick the lock due to the amount of force the spring exerted on the cylinder. The surprising thing here was that this modification seems to be relatively easy to do by tapping out some threads and inserting a set screw to hold in the spring.
Locksport and lockpicking are a great hobby to get into. Most people start out picking small padlocks due to their simplicity and ease. It’s even possible to pick some locks with a set of bobby pins. And, if you really want to see how easy it is to defeat some locks and/or how much good the TSA does for your overall security, you’ll want to take a look at this, too.
Thanks to [TheFinn] for the tip!

Lockpicking has become a trademark skill of hackers all across the world, and is regularly taught at hackerspaces and maker faires. But a lot of the time, the sets have already been made or bought online somewhere. However, [Sean] has demonstrated how to create a lock picking set with ordinary paperclips in the video embedded at the end of this post. Wikihow also has these awesome instructions on how to build them.
What’s great is that the material for these picks are easily found. There are other ways to fashion a set together. For example, street sweeper bristles can be used. And electrical metal tape is a good material as well, but these paperclip sets are, by far, the most accessible. Pretty much anywhere that has office stationary supplies will have mounds of these little metal clips lying around.
But how well do they work? Have you made a paperclip lock picking set before?
If so, let us know in the comments, and tell us how well they did.

The Stimmmopped is an electronic guitar tuner made to be used as a guitar pick. This uses two LEDs synchronized to blink at the exact frequency of the string you are tuning. Pluck the string with the corner of the PCB and then shine the light on the string you are tuning. As the vibrating string moves back and forth it will only pick up the spot of light when the frequency matches that of the blinking LED. Once in tune, both red lights will appear to be constantly illuminated and immobile on the string.
An Atmel ATmega8 is used to control the device, interfacing with two buttons and a seven-segment display to choose the pitch currently being tuned. Gibson has a robotic guitar that features an auto-tuning mode, but if you don’t want to shell that much this low cost and simple build is for you.
Speaking of laser engraving, the blackbag blog announced that Toool has designed 2 unique picksets for The Last HOPE this year. First is the credit card sized snap-off set seen above. They have named this one The Last HOPE emergency pickset. The other pickset is a new version of the ‘double sided pick’ series. This set consists of picks with the same tool on either end, but they are sized differently. This set will contain 8 picks with promised improvements.
