Door Lock
StudentRND has a cool door lock. It can be accessed by key, RFID, and Twitter!

History
Inspire
Normal doors are boring, entirely mechanical with no electronics at all. At StudentRND we love to add that little extra spark and learn something along the way.
The StudentRND staff and myself, Adam Ryman, felt very limited by what a standard office door offered us. Anyone who needed access to our space either had to have someone unlock it for them or needed a key, which could be copied. We wanted a better solution, we wanted the ability to unlock our door remotely, give a take access quickly, and reduce the number of keys to prevent unauthorized copying.
Create
StudentRND's front door now has an Adam's Rite electronic strike installed, which is connected to an Arduino to process all of our commands. The functions of the door includes, ability to be open via Twitter, switch to control if the door is forced open or closed, automatically unlocking if the open sign is on, and a key backup.
Learn
We learned about the involved process of purchasing parts for a very important piece of infrastructure. As our door is our most important piece of security, each piece has to be triple checked for compatibility and security.
Mounting our door lock and related equipment was a learned experience as well. Every piece has to be mounted in near perfect condition in order to achieve the maximum security.
And finally the electronics, our COO, Tyler Menezes, learned basic electrical engineering for this project. The circuit created took over eight hours of researching and testing.
Every student that touched this door lock project gained something, from learning about basic door/door lock mechanics, circuit design, and the importance of research to a important project.
How to Use
General Public
Contact Edward Jiang, Tyler Menezes, or Adam Ryman to request unlocking if priorly arranged.
Staff
Swipe RFID token if in person or Tweet @srnddoor "please open xyz" (Or anything, but the door will not like that).
