The guys over at Nootropic Design have created a cool version of the Etch A Sketch, the Hack A Sketch.
The Hack A Sketch was made using a Lenovo Thinkpad notebook, an Arduino board, and two potentiometers, to make a digital version of the Etch a Sketch. Check out the video of it in action below.
How the Hack A Sketch Works
An Arduino board reads the inputs from two potentiometers (the knobs), and sends the information via USB to a Processing sketch which displays the path of the stylus on the screen. This was extremely easy to build because the Arduino is just running the StandardFirmata firmware. No custom code on the board. The Processing sketch was surprisingly easy to write. Using this really did feel like using an Etch-a-Sketch.
The Arduino board serves as the brain of the Hack A Sketch, interpreting the movements of the potentiometers, which act as the knobs. These knobs control the X and Y axes, just like in a traditional Etch A Sketch. The data from the potentiometers is then sent to the Processing sketch, a flexible software sketchbook and a language for learning how to code within the context of the visual arts. This Processing sketch translates the data into visual output on the screen, mimicking the drawing experience of the original Etch A Sketch.
Applications and Future Potential
Very cool, it works just like a regular Etch A Sketch. This project not only brings a nostalgic toy into the digital age but also opens up a world of possibilities for further innovation. For instance, the Hack A Sketch could be expanded to include additional features such as saving and sharing drawings, adding color, or even integrating with other digital art tools.
Moreover, this project serves as an excellent educational tool. It introduces users to the basics of electronics, coding, and digital art. By building their own Hack A Sketch, individuals can learn about the Arduino platform, how to interface hardware with software, and the fundamentals of Processing. This makes it a valuable resource for educators looking to teach STEM concepts in a fun and engaging way.
Head on over to Nootropic Design for more details on this cool digital Etch A Sketch. The website provides a comprehensive guide on how to build your own Hack A Sketch, including a list of materials, step-by-step instructions, and the necessary code.
