hi im trying to make a coffin open up when a motion sensor is triggered.. im lost on finding the stuff i need and most of the sites i look on dont have a parts list or where to get the parts at.. i found a site that helped alot but the only part it says i need is a 3 way solenoid valve and i cant find one around me.. maybe its just me and im not lookin in the right places but if anyone can help me with getting a parts list and any additional help i would be soo greatful.. thanks in advance

I haven't built anything with air yet so its probably best that i don't advise you on what you would need for this, but another way to do this would be with a wiper motor, this could be purchased from monster guts or you can usually get them very cheaply on ebay. You would also need a good power supply, 5v to 12v, the lower the voltage the slower the coffin will open, as well as this you should make sure that the power supply has enough amps, 4-5 amps is normally enough. If you set up a cam like this then you should get the closing/opening motion your looking for http://www.technologystudent.com/cams/cam1.htm

Hope this has helped

Thanks

that helped some but i kinda want it to open and stay open for a bit then close... i plan on using a wiper motor to make an old lady on a rocking chair..

Oh i understand how the motion sensor would do that if you were to use air. Just incase you do decide to use a wiper motor, you could always purchase a prop controller such as the nerve center to achieve your desired effect.

Thanks

Phil

Here is mine



I have kit if you want it.

.75 bore 6 inch stoke double acting cylinder with rod clevis and mounting hardware
4 way solenoid
20 feet hose
picoboo105 with beam or motion sensor

PM me

I agree with Phil on starting off with a wiper motor if this is new to you. However I skipped that step and jumped right into pneumatics so it can be done

You can get all you parts from

http://www.frightprops.com/

You can use a 3 way solenoid for this prop because the weight of the lid will close it. Which means a single acting cylinder.

This may help you out



So your part list would be as follows

1 x 3/4 bore 6 inch stroke single acting cylinder and mounting hardware usually rod clevis, and rear pivot

1 x Male Connector Push-On Elbow (choice of thread size)

1 x Quick Connect - Male Threads

1 x Male Connector-Push-On Fitting

20 feet of Polyethylene Tubing

1x Exhaust Muffler

1 x 3-Way Solenoid (choice of 12VDC, 24VDC, or 110VAC - MAC or STC brand)

Then if you wanted a controller and a PIR/beam/mat sensor add that.

INDUSTEN you are the best.. i went on that site and ordered a kit.. it has everything i needed except the cylinder ( wich i already have)... i couldnt find a 3 way solenoid valve ANYWHERE until i went there.. i appreciate it pal so thank you.. if yous have any ideas on what might be cool to do for halloween im up for anything.. i have ideas that ima do but anything extra would be nice.. THANKS AGAIN INDUSTEN!!!!!!

How do you add the effect of the sound to the prop? Also, How do you keep it going for the banging effect instead of a one and done deal?

Thanks. Great prop.

It's kind of hard to explain. But watch my video of my groundbreaker kit for sale in the for sale section it explains alot.
