The PropMaker is wired to a time-of-flight sensor to detect when any unsuspecting mortals foolishly draw too close to. Ought to that occur, they’re greeted by the gargoyle with glowing crimson eyes, scary sound results, and unsettling messages displayed on an RGB LED matrix on the tombstone.
Trick-or-treaters are additionally welcomed (if that’s the proper phrase) by a 3D-printed raven that stands on the bottom subsequent to the tombstone. A servo triggers it to maneuver its head to get a greater take a look at its approaching prey.
The software program was written solely in CircuitPython, which has help for the entire {hardware} elements used within the venture. The venture web page additionally makes the code accessible, so it might be a easy matter to breed the venture, and even customise it to fulfill your personal ghastly necessities.
Design recordsdata can be found for printing the raven, however you may not have such a simple time discovering the very same Styrofoam mannequin to begin from. Thankfully, it shouldn’t be very difficult to make use of a considerably totally different mannequin as a place to begin, in case you are prepared to be a bit versatile. Whichever approach you propose to go, the step-by-step instructions supplied by Adafruit ought to go a great distance in the direction of getting you to your aim. Glad Halloween hacking!
