OK so yea, this project is super perfect for Halloween, but, 100% would stay on my wall indefinitely. As in, it would become permanent wall decor. From grajohnt on Hackster.io:
Caveats and Failures
This project is not perfect. Dumb things were done. I will talk about the dumb things and how they could have been less dumb. We all learn through failure, and being humble and talking about failure is a great way to learn!
tl;dr: There’s no such thing
Like many of us, I sometimes buy things on impulse (dumb_thing++). BigLots was having a sale on ridiculous animatronic stuff for Halloween, and my wife had made the mistake of putting me in charge of decorations (dumb_thing++, but not MY dumb thing, so dumb_thing–). I bought an animatronic triceratops skull, which is honestly only marginally Halloween-related. When triggered by motion, it would open it’s mouth and screech at you for far too long for comfort.
So, I did what any one of us would do with an inexpensive impulse buy that we considered throwing away: I took it apart to see how it worked.
