Creative Coder Tekavou Brings Etch A Sketch Art to Life with Modified Chinese Postman Algorithm
A creative coder, known as Tekavou, has combined graph theory and playful aesthetics to create unique art using a modified Chinese Postman Algorithm. The art is generated by stitching images into one continuous SVG path, which then drives encoders to produce drawings reminiscent of an Etch A Sketch.
Tekavou's innovative hack uses a Raspberry Pi Zero W 2, a camera module, Inkplate 6, and rotary encoders. The process begins with taking a photo, which is then converted to black and white. A skeleton of black areas is created, and the modified Chinese Postman Algorithm is employed to stitch the image into one continuous SVG path. This path drives the encoders, resulting in a drawing that resembles an Etch A Sketch.
Originally, the Raspberry Pi handled all the processing. However, it was later replaced by a Mac Mini M4 Pro for faster processing. Tekavou has also developed Teka-Cam and TekaSketch, which transform real photos into Etch A Sketch art. Looking ahead, Tekavou plans to improve the hack by adding video support in the future.
Tekavou's innovative use of the Chinese Postman Algorithm and graph theory has resulted in unique, playful art that combines the serious with the whimsical. With plans to add video support, the potential for further creative expression is exciting. The switch to a Mac Mini M4 Pro has also ensured faster processing, allowing for more intricate and complex artworks.
