Cheap motion activated coffin

Step 4 Adding pnuematics

I used a motion detector to activate my screen door closer air cylinder. To send air to the cylinder I used a washing machine solenoid. To add more movement I activated the solenoid with a 12volt car flasher and a relay.

the motion detector is set on test mode so it only stays active for like 3 seconds at a time the flasher relay just makes in turn on and off while active

using the flasher relay does the coffin continuously open and close once activated?

Its not actually split into 3 directions it is an in and 2 out. In order for the lid to fall back down I needed a way to let the air back out so the other out leg is just a piece of tubing with a regulator on it to control the speed of the air coming out and the speed of the falling action.

what is it that releases the air quickly when it shuts off? why is the air supply split into three different directions. Thanks for your info. great Idea.
