The Makers local 256 sent us this USB authenticated deadbolt prject. For roughly $60 these guys built an authentication system that reads the serial number off of the chip in a USB storage device. The actual content on the memory in the USB device is not used at all. They are using a Freeduino board to control its behavior. It has a magnetic sensor that keeps it from initiating the lock when the door is open. They mention that they are using Transparent Aluminum as an enclosure, we assume they mean the Star Trek variety, not Aluminium oxynitride. Be sure to check out the video after the break.
Congratulations to [John Keppel] for his winning t-shirt design. He wins a Dash Express, an in-car navigation device with both cellular and WiFi data support. It’s running Linux on top of the Openmoko FreeRunner’s hardware platform; yes, [John], we do expect you to hack it. We’ll let all of you know when we plan on putting the shirt into production. Thank you to everyone that entered!
It looks like Uhlmann & Zacher have developed a patch to keep locks from being opened using a ring of magnets. In addition, the lock now logs successful entries without credentials in case something like this comes up again.
Putting a custom designed electronic lock on your space seems like a geek right of passage. For our latest workspace, we decided to skip the boring numbered keypad and build a custom RGB backlit keypad powered by an Arduino. Instead of typing in numbers, your password is a unique set of colors. In today’s How-To, we’ll show you how to build your own and give you the code to make it all work.
