Etch-a-Sketch in Operation
SparkFun Electronics is showcasing a current class venture from Alex Dow on the College of Colorado. Derived from a field filled with SparkFun widgets, Mr. Dow was capable of concoct a digitally managed Etch-a-Sketch.
In contrast to the extra typical analog model, Mr. Dow’s mannequin makes use of a pair of ADXL322 accelerometers connected to 2 human wrists for driving two separate stepper motors. These motors, in flip, pushed by a few EasyDriver PCBs, spin two rubber bands which were independently looped over every of the Etch-a-Sketch management knobs.
The true “brains” behind this inventive endeavor is the beloved Arduino. The result’s yet one more irritating variable added to one of many American toy business’s most enduring and virtually not possible to grasp artifacts. Add a Slinky to the combo and also you’ll have an ideal pastime for whiling away these dreaded semester ultimate exams.
