LARGE ETCH A SKETCH DRIVER

This solution allows the Raspberry Pi to not only read the rotation of the knobs when a person is using the Etch a Sketch interactively, but spin them realistically when the software takes over and starts doing an autonomous drawing.

The knobs are connected to stepper motors with custom PCBs mounted to their backs that hold a A4988 driver chip as well as a AS5600 absolute magnetic rotary encoder. To make his jumbo Etch a Sketch functional, spent more than a year developing the hardware and software necessary to read the user input from the two large 3D printed knobs mounted under the TV. But whereвЂ™s the fun in that? It took hundreds of hours to print the shell. That alone would be a pretty neat project, and had just thrown some videos of designs getting sketched out onto the display, he could have achieved a similar end result with a lot less work. With a Raspberry Pi and some custom electronics onboard, it can even do its own drawing while you sit back and watch.ДЄt a high level, what weвЂ™re seeing here is a standard Samsung LCD TV with a 3D printed Etch a Sketch shell mounted on top of it. A perfect example is this giant wall mounted rendition of the iconic art toy created by. Considering one of the biggest draws of the original Etch a Sketch was how simple it was, itвЂ™s always interesting to see the incredible lengths folks will go to recreate that low-tech experience with modern hardware.
