We are IoTalabs and we are a group of Internet of Things enthusiasts that love hacking together different devices. We've been working on many projects (check out our current project http://doteverything.co/) and we wanted to share our experience making a digitized drawing board!

Drawing on a computer can't match the ease and accuracy of moving around a pencil on paper in real life. A mouse or trackpad is far too cumbersome to maneuver, making even a stick figure hard to look good. But what if there was a way to map actual pencil strokes onto the computer so that you could still draw naturally AND have your creation on your screen? This is why we made Back to the Drawing Board!, a simple way to use a pen or pencil and draw on actual paper which translates your drawing on to a screen.

We utilize the power of a BeagleBone Black to do the core image processing of this project. Even though the processing power to convert physical drawings into digital ones is not intense, the power of the BeagleBone makes it a smooth and fast process.
