Thread: adding sound to static props

Tweet

I'm pretty new to making electronics for my props. Ive made led stuff before but thats about it. Im interested in adding a speaker with a motion sensor on one of my grim reapers so that when someone walks by, he greets them with a scary voice. Just want him to say a quick greeting, nothing elaborate. Any pointers on what i should use to record the sound and play it along with a motion sensor i could use?

I have been trying to find something similar and I came across this which is a mp3 player that you can connect a motion sensor to. I don't what exactly you were looking for but it looks like it could work.

This may be what your looking for:
50 second USB recording module
You should be able hack the motion sensor to trigger the board.

Heh, you guys must be made of money if you use those on more than one or two props.

Try this:

SAW 3 DIGITAL VOICE RECORDER | AllElectronics.com

These little guys are ridiculously easy to hack and even come with batteries. There is a link in the comments section on the product that'll take you to all the hacks. Basically for 4 bucks (the device is only 2 bucks, but you'll wanna buy two jacks and some resistors which will add up to around 1.50) you'll have a self-contained 30 second voice recorder with EVERYTHING you need. As for activation, applying a little voltage to the play button will start playback.

I love these little things, bought 5 of em. Halloween is getting really close but if I have time I'll make a write-up regarding some of the things you can do with them.
