The LibeTech QR code-based entry system is a unique way to do away with traditional keys and swipe cards. Using a simple web interface, approved users are added to the system via their email addresses. Once added, these users are sent a QR code via Email, that when held up to the system, allows them to unlock the door.
LibeTech was a project that I developed a few months ago in my *free time* while I was a Senior at Cornell University. Three friends had entered the annual business plan competition with the idea to ease and customize the check-in process at hotels. Fascinated by the idea, I joined the team as a technical director. I had been looking for an opportunity to play with the beaglebone linux microcomputer for some time, and this was the perfect opportunity.
LibeTech ended up making it to the finals (top 5 out of over 30 teams) in the business plan competition, and we won both the Verizon and GE Innovation awards at BOOM 2012. After giving it a lot of thought and talking to industry professionals, we decided that attempting to bring this product to market would not be the way the go for a number of reasons. Instead, I’ve decided to release the project under open source licenses.
All the materials needed to recreate this system are now available on my LibeTech portfolio page. You’ll also find more photos, a video detailing the inner workings of the system, and more technical info. Go check it out!

Thanks for sharing this project! :)
Do you have a wiring diagram of this project? Especially from Beaglebone to the door strike via the diode?

Take a look at the source code here: https://github.com/sciguy14/LibeTech-QR-Entry/blob/master/entry.py
It lists the I/O pins that the LEDs and the door strike are hooked up to. The door strike is just a simple N-Channel MOSFET controlling the strike mechanism.
