There’s a common misconception in the maker world that the gadgets we build need to be useful. Or practical—or at least serve some sort of purpose. That’s a myth that William Osman has debunked again and again, and his latest build is just further evidence.
This creation is a beanie, that you wear on your head, which smokes and coughs. Why? Well, if you’re asking that question, you’re missing the point. This build is all about the “what” and the “how.”
We’ve already cover the “what”—it really is just an animatronic beanie that moves a mouth-like contraption as it makes coughing sounds and ejects smoke. The “how” is pretty straightforward for most makers: a laser-cut wood frame houses an Arduino Uno, which controls a servo to move the mouth. The Arduino also triggers an Adafruit sound effects board, so audio clips are synced with the mouth movement.
As you can see in the video, the results are pretty entertaining. Osman spent some time wandering around Ventura Beach wearing the beanie, and the reactions of passersby can best be described as “confused.” But, what else would you expect from a project like this?
