First animated coffin test

Hi all,
I got the wiper motor installed in the Buried Alive coffin last night, and tested the lid opening capability. The motor handles the load easily. Right now the the control circuit isn't installed, so the lid opens and closes repeatedly. After the controller is attached, the lid will do an open-pause-close sequence. There's more detailing to do on the coffin, but I should have all the assembly and circuit installation work done by the weekend. Here's a short video of the lid in action:

More to come...

Lilly, I get the motors from Monster Guts. I used a 5VDC power supply with the motor set in the "slow" position for this prop. Get the "Power Pack" deal - it comes with the connector which makes attaching power very easy. Dean's a great guy, and the motors are powerful and very quiet.

Thanks SG!
I'll be taking lots of pics this weekend. I'm also using a custom circuit that will open the lid, pause for a few seconds, then close it again. The circuit uses an opto-sensor to index the motor at 180° (lid open), then lets it complete the remaining 180° (lid closed). It then waits for the next trigger. I'll post pics of the motor attachment and crank arm.

Great Idea

This is a great idea and I have a special interest in learning to work with motors for animation. I have been collecting all kinds of different motors that I have seen used for many different props. Do you have other props that you have put together. I would like to see more.

I'm going to recycle the groundbreaker from this prop. I'll attach one hand to the edge of the lid to make it look like he's pushing it open. I'll drape some cobwebs on him, and use a pulsing light to illuminate the inside. I may install an MP3 player to give him a voice. Haven't decided on that yet, though.

That's a great prop. I'm also wanting to animate the lid on my coffin so am looking forward to the close ups of the crank mechanism. I got my last motor (power pack) from Dean and I'll second that Monster Guts is a great place to do business with.

Here's a video of the coffin with the motor controller installed. The lid opens and closes once when the PIR is triggered. The pause time is set to 6 secs. It also has an MP3 player controller (the blinking red light) that will play a scream when the lid opens. I'll assemble the remaining panels after I get all the rest of the internals attached. I have a lot of pics of the motor linkage etc, but I don't have a good JPG editor here; I'll post those pics on Monday.
