Thread: Some questions

Tweet

I was looking at the Cemetery Fence By Scott Messinger and I think I'm going to make a couple of those for my yard. How hard would it be to put LEDs in the skull's eyes and where can I get the LEDs? Also what do I need and how would wire everything together if I wanted to make some skulls pop out with compressed air?Like in here. Another question I have is how to I make props Motion/Sound activated and how I add a speaker box to a prop?

Im not a pneumatic guy so ill let someone else take care of that. Wiring leds your gonna need resistors and 9 volt clips. Here is calculator for wiring and which resistors to use. LED calculator for single LEDs

If you've never visited the Wolfstone page, take a little trip over to HauntMaven.com - Wolfstone's Haunted Halloween Site , click on the extreme haunting link and you'll find all kinds of answers to your questions (and more than a few new ideas!). Hope it helps.

Ok thanks. So if I want to have the skulls have LEDs I need to get this? Also I'm still not really getting the whole pneumatic compressed air thing yet. It goes Compressor-> Solenoid-> Pneumatic Cylinder right? What is a Solenoid and do I really need it because the guide on wolfstone is kind of confusing. What type of Cylinder/Compressor do I need to make the popping skulls and other props like I posted in my last post?(hopefully not too expensive)

Chris, Yes you need a solenoid. It serves as the valve to turn the air to the cylinder on or off. You also must have a regulator, this controls the amount of air pressure to the cylinder and ensures proper and most importantly safe operation.

Many people use a washing maching solenoid valve, I've used ones for a dish washer or refridgerator ice maker. My recommendation is to get a surplus valve from ebay or a surplus outlet. At a minimum you need what is called a three way valve. Why? This allows air to enter the cylinder and activate(rise) it but also allows the air to exit (retract). If you use a washing/dishwasher valve you have to add a bleed off between the valve and the cylinder. this is usually a tee with a small needle valve, with this set up you'll lose some of the air going in through the bleed of line but with some adjusting you can get the cylinder to activate and retract properly.

Ok, is there a good tutorial setup with pictures so I can see how it all connects together?

Chris, here's a how to for the washing machine valve, there is a good pic on page 2 of the layout complete with labels. Air Trigger -Creep Crafters .Com-
