Thread: Making a gravebraker have some ?s

Tweet

As title says. I have the arms built and hinged up. Tomorrow ill be adding the air cylinders. I have a question on sounds. where can I get the speakers? And what source of a music player I need to hook up to the motion sensor?

Depends on if you want low tech (stone age ) or digital. For low tech you can get it done in about 5 to 10 minutes. That is if you have a boombox or a old cassette recorder.

I assume with the grave grabber you'll probably be using the classic zombie moan or a combination of moaning and brains or something like that. A endless 15 second cassette would work or a two hour cassette taped on both sides. Plug it into the motion detector and push the play button down and it will come on as soon as the prop is activate.


Digital you could use a MP3 player or a Digital recorder and a pair of PC speakers (thrift store ...couple bucks). Then you would need to add a relay and hack the MP3 player to come on when activated.

You might want to think about a boobox or PicoBoo controller with sound...you will need some type of prop controller to make your cylinders fire at different rates

I use Fright Ideas controllers for most of my controller/sound/trigger needs.....Hope that helps....ZR

I use a cheap MP3 player and computer speakers. Have the MP3 player set to loop the audio and then use the motion sensor to turn the speakers on and off.
