sound clip played from trigger
« on: July 04, 2014, 11:08:01 am »

This may not be the place for this, so if you know of a better source please let me know.

Does anyone have input on how to achieve the following?

A "game" shooting target has a 12vdc output when the target is hit.
I want to be able to play a custom recorded sound (an explosion, a woman screaming, a cat meowing, etc) when the trigger outputs.
Each target would only have one clip to play on demand.
Seems logical that an IC chip (?) can hold the file to be played, but recording to the chip, playing the chip, and outputting a line level signal from the chip is what I have no experience with.

Any advice or resources would be greatly appreciated.

Thanks,
David

You could try a Denon DNF-400.

You will need to convert your 12V signals into closed contacts, but this unit can trigger different audio clips on different closed contact triggers.

That would be the way to go.

You would have to place a 12v relay between the target and the sound module which could control the playback mode with a single closure of the relay through the parallel port. The schematic is located in the users manual. Then set the playback mode. Set the unit to random play, close the relay, sound plays, stops when done, and next random sound is ready to play. Easy peasey.

For 8 tracks or less, a cheep'n'cheerful solution could be one of these :

the Rapsberry PI with the GPIO could easily be programed for that. They aren't necessarily the most reliable thing but if you are wanting one to play a file for each target it would be the cheapest route to buy multiples, and keep the each target separate.

Also look into some of the Halloween sound effects units, many have contact closure triggers.

Thanks all.  But would still like some input on the possibility of building a circuit, if practical.

I've used this device on many, many occasions;
https://www.sparkfun.com/products/11029

Up to 18 trigger inputs (closing contact, so relays would be required) playing an mp3 each.
You need to do a little buffering because the audio output is DC Biased, but there are instructions in the comments section of the page.
Great piece of kit for the money.

You can get an arduino to play .wav's too. It's not very high quality, but it's do-able.

This one looks promising.  http://www.jerryselectronics.com/mp3player/mp3player.htm
even has an output trigger of it's own,
