How to Make a Terrifying Zombie Groundbreaker Animatronic at Home [Videos]

Want to make the most terrifying Halloween lawn ornament ever? Instructable user Trimbandit made this really scary animated zombie groundbreaker using two pneumatics to make the thing appear as it’s clawing its way out of the ground. Watch: (There’s also a really cool animated hangman in the video.)

And here’s the mechanism:

From Trimbandit:

*NOTE* I recommend starting with a low amount of pressure when testing and increasing from there until you are satisfied with the speed. The cylinders are very powerful and you don’t want to rip everything apart.

You will probably want to either weight or stake down the groundbreaker to keep it from shaking across your lawn. I ran a considerable length of air hose so I could keep the compressor in the back yard, since it is rather noisy.

Interested in making your own? Trimbandit’s “How-to” is right here!
