I've been trying to find some cheap sound modules that play sounds off an SD Card. I saw Sparkfun has these Audio-Sound Breakout - WTV020SD but $19.95 seems a bit pricey for what it is. I think it should be closer to a $10.00 or $12.00 module.

Has anyone come across any simple and maybe $10.00 or less modules that play sound off an SD Card? I'm trying to sound enable a bunch of Halloween props and use Netduino's and Basic Stamps to control both sounds, motors and motion sensors.

If it is made in asian(china, malayasia, signapore, etc). The prices around should be 10 for $2.99(directly frm factory).
I have seen projects such as mcu, avr. Some written in assemblerm basic stamp and mikroc/mikroBasic, proteusand mplabs, frm website and youtube

Radio shack sells a $12 module that plays back a recorded message (up to 20 seconds). If you're handy with a soldering iron and a multimeter, you can figure out what lead to short to ground (programmatically, of course via an I/O pin) to make it play on command. It's called a Recording Module if you want to google it. I got one for the same purpose.

I actually designed a version much like that and hold the patent on it back in 1996. Holds up to 90seconds. I have plenty of those just lying around. Was really trying to go more towards larger storage media that can be easily changed out (like SD Card).

For this year's Halloween display I just ended up breaking out a bunch of my 90 second PSound boards but will research designing a cheaper SD card version for next year.

what about $5.95? with free shipping? :) http://www.ebay.com/...=item2570d4e456 I have not tested this module, and are not sure how equal it is to the sparkfun model, but cheap anyway :)

That is exactly what I was looking for. Haven't seen them that cheap anywhere. Thanks for the link!

hey guys, I'm curious. Is this still the best option to play back audio files on a Netduino plus 2? I was hoping to be able to play wav or MP3 files from the SD card already on the duino. Ultimately, I want to output audio to an audio jack and put that into an input on other device. Is that possible without another component ?

If you want to do it from the built in SD you would still need extra circuitry.  You would need to add an 8 or 16-bit DAC.  Best way still is the card listed above or a SOMA-14D or any of the audio shields sold by places like Sparkfun or Adafruit.

@Dave: I got a couple of these modules too so if you try them out, maybe you could share some code? If I remember correctly, it uses an SPI interface to trigger different songs/sounds.

@skobyjay: You might want to check out the mp3 player I wrote using a breakout board for the VS1053B audio decoder/player. There's some code in the end of the thread:

They are the same as the SOMO-14D that Stefan used.  I am using the code from his demo.  I forget where the thread is but its on the forums.  I've had a few little bugs but they may also occur on the SOMO-14D.  Stefan has not had time to try my Repro yet to see if it acts the same.

You can find Stefan's SOMO-14D code and samples here: http://netmftoolbox....pported devices

 

It's one of the few devices that I don't have from Stefan's list of devices. I think perhaps it's time to order me some SOMO. :)
