Adding a custom built electronic lock somewhere in your living quarters can be viewed as a geek’s right of passage. The team over at Hack A Day decided to take this one step further and ditch the boring number keypad and replace it with a custom RGB backlit keypad.

Instead of typing numbers in to unlock the door, you use a unique set of colours as your combination. The guide includes step by step instructions with pictures for building the lock, as well as a full parts list and code to make it work.

You can find the Hack A Day guide here. Or part 2 of the guide where they go from prototype to fully functional dor lock.
