Thread: motion activated sound effects?????

Tweet

Ok. I have a few sound effects on my computer. I can burn them to a CD (each effect gets its own CD)

I am wanting to set it up so that a motion sensor will triger the sound effect.

Example. I have a raven sound and want it so that when ToT's walk by, the motion sensor will triger the raven to crow.

How can I do this?

I was thinking about a CD player, but with the power OFF untill the triger is activated, it will take too long plus I would have to actualy push PLAY to start it.

I do not have means to rig up any kind of computer control mother board thing. each prop needs it's own independant sound player.


Thanks

The way to do this would be to use a motion sensor to trigger a Cowlacious Chipcorder board. Basically, using a audio recorder board, you put the sound effect onto an ISD chipcorder, mount it onto the aforementioned Cowlacious board, and hook the board up to some PC speakers and a PIR motion detector and it'll do exactly what you're looking for.

That may be a bit pricier than what you're looking for though. It will do exactly what you want though.

Ok. This is a little beyond my norm so let me see if I get this right.

is THIS ALL I need??? (not including the speakers and power)


I hate to ask this, but is ther ea way you (or someone) could make a step by step on how to use this. THe price is not a problem. (cheaper then I would have guessed)

I just dont want to buy something and find out I need another part thats $500 to make it work.


Thanks

That's not all you need. You need that circuit, one of the sound chips that mounts on to it, a pair of powered PC speakers and a motion sensor. I've never used the cowlacious board myself, I have built similar items from scratch. I would imagine someone here with experience with this board could whip up a better how-to than I could.

Honestly, in my opinion, if all you're doing is playing a crow sound, you could record the sound with a few seconds of silence in between "Caws!" and just have it loop over and over. Less hassle than trying to have a motion sensor involved.

Well. I'll also have a prop like the casket in Disney's Haunted mansion in the conservatory, and the same sound effect, "let me out...". I don't want that running ALL NIGHT LONG.

If it's a simple sound.....use a loop cassette and a tape player. You can or should be able to get both for under $5.00. RS will have the loop cassette for around 3 or 4 dollars and if you don't have a cassette player you will be able to get one at any thrift store...probably around 1 buck.

Push the play button down and plug it up to your motion detector. When someone walks in front of the detector....Your Crow will crow.

If your cassette player has a mic jack, you can record the sound straight from your PC. If not you can hold the recorder up to the speakers.

Simple, cheap, easy and will work....what more could you ask for

You could always have the sound playing over and over and have the connections to the speakers on a switch. Throw the switch, and then the speakers work!

Couldn't you just hook the motion sensor to a relay that triggers one of those 20 second Radio Shack sound modules with your crow sound on it?
Or some similar setup?
Electronic Goldmine still has PIR sensors in stock for $6.00. I've bought 3 of them and they work great!

Not sure what your talking about "sound modules". do you have a link or something?

Thanks
