Video of the Halloween display

Not great quality, it’s hard to shoot in the dark, with fog. But hopefully you’ll see some details of the display. We had a blast last night with a lot of kids (and adults) enjoying it! Many screaming, some crying 🙂

Spider Pneumatic Lift – Halloween 2012

Time to write about some details about our Halloween 2012 project. First off is the Spider Lift. This is a simple mechanical design, basically a hinged wedge driven by an air cylinder. The double-acting air cylinder is hooked up  to a 5-port 4-way 12v solenoid valve with speed-adjustable mufflers. This valve either directs air to the top or bottom of the cylinder, so it will go to either position with pressure force. Applying 12 volts will send the air to the opposite side. I have the resting position at the top, so when the spider is triggered it will come down/towards the visitor, while a red strobe flashes and scream sound effects are played. Most equipment from http://www.frightprops.com. Yes, those are old cabinet doors 🙂
