Hacked Electric Toothbrush Defeats Locks With Ease

The movie version of lockpicking tends to emphasize the meticulous, delicate image of the craft. The hero or villain takes out a slim wallet of fine tools, applies them with skill and precision, and quickly defeats the lock.

This expedient electric toothbrush lockpick is a surprisingly effective example of the more brute force approach to lockpicking. As [Jolly Peanut] explains, pin tumbler locks work by lining up each pin with the shear line of the cylinder, which allows the …read more

Of all the ways to open up a lock, there are some tried and true methods. Keys, combinations, RFIDs, picks, and explosives have all had their time and place, but now someone else wants to try something new. [Erik] has come up with a lock that opens when it is shown a pattern of colors.

The lock in question uses a set of color coded cards as the “keys”. When the cards are inserted in the lock, a TCS230 color sensor interprets the pattern on the cards and sends the information over to an Arduino Uno. From there, the Arduino …read more

3D Printed Key Saves the Day

When [Odin917’s] parents went away on vacation, they took the apartment mailbox key with them. With the mail quickly piling up in the mailbox, he needed to get in there. He could have had the building super replace the lock, for a fee of course. Instead he had his parents email a photo of the key, which he used to 3D print his own copy.

Using a photograph as a template for a 3D printed copy is nothing new. We’ve covered it in-depth right here. However, this is the first time we’ve seen the technique put to use for good …read more
