Mini-Robots and the Invasion to Come: The Gift That Keeps on Giving

Xmas Robot

This Instructable was originally created with Xmas in mind, but it’s one of those perennial cool ideas: you make a little robot that stores solar energy doing the day and blinks to “radio home for reinforcements” once the lights go out.

Sounds kinda neat. But if you wake up one day and find three on the tree where you started off with just one, you might want to run like hell. Just saying.
