December 18 - Just in Time Parts vs. the Junkbox
The Halloween Prop Dropper
The Prop Dropper is a “quick and dirty” Halloween project you can probably put together in a single night with just a small microcontroller, a couple of servo motors, and a few bits and pieces from the ol’ junk box. Designed to detect the presence of a person, rapid-deploy a small prop, display it for a moment, then wind it back up out of view, ready for its next victim!
