Yes he is indeed pneumatic. I built the basic coffin pop up rig that is found here Halloween
I used the mac valve for the air wich is way better than the sprinkler valve and only cost $11. I dont have a video of the bare rig only some still pics.This year i am going to make a nice video of all my props and how they all work. The zombie was made from a head and hands from death studios. He does operate very quietly. Since this video was made i have upgraded his sound system to a 50 watt guitar amp and he really kicks now. I also added a bleed valve to the exhaust port on the mac valve to control how fast he resets.
Thanks for the additional pics. I like you new zombie much better than the old one
We are making a pneumatic pop up in a coffin for our funeral theme this year. Hubby's done other pneumatic pop ups without a problem (well except for a flying head once in a while during the test phase lol) but he's always interested in how other people do it and I'm sure he'll want to check our your new valve.
