Plotting with Etch-a-Snap

So far we've built the Etch-A-Snap and processed an image to produce a 1 bit image. In this part we’ll look at how to take this image and generate the draw instructions for the plotter. Etch-A-Sketch is a very simple 2D plotter which is limited to drawing

Etch-a-Snap Image Processing

Etch-A-Sketch is a very simple 2D plotter which is limited to drawing a single unbroken line, of a single thickness and color which is dark-ish on a silver-ish screen. To be able to plot a photo onto the Etch-A-Sketch we need to transform the image so that — 1. the resolution

Drawing with an Etch-A-Snap

The image processing produces a 1 bit image (B&W) of 240x144 pixels. The next step is to take this image and convert it into movements for the motors. The way this is done is governed largely by the design of the Etch-A-Sketch — any drawing must be made in

Building the Etch-A-Snap

Etch-A-Sketch is built from a pocket Etch-A-Sketch and 6 individual 3D printed components. The control is handled by a Raspberry Pi Zero (or Zero W) and a custom circuit board containing motor drivers and inputs. The wheels are driven by two stepper type motors mounted on the 3D printed frame,
