    Any low cost, low energy solutions for playing MP3 files from TEENSY 2.0 ++

    I have an Adafruit solar lipo charger powering a 6600 mAh battery and Teensy 2.0 ++, which is driving some LPD8806 LEDs, Im arranging for a sensor to trigger some kind of sound to add to my project. The sound im planning on using (a burp) is short and simple. Any ideas? Thanks

    If you just need a single static sound, something using a 1820 chip might work when you add a cheap speaker. You record the sound on the chip, and then you play back the sound under program control. Here is an ebay seller that I've bought from before that sells a 1820 chipset: http://www.ebay.com/itm/ISD1820-voic...item4ac43fc2d2.

    You might want to check the data sheet, to make sure whether you need to drop voltage from 5v to 3.3v for this device.
