It's a 2x20 second voice recording module (electronics123.com) with the output connected to a LM386 800 milliwatt amplifier chip, both running from 6 volts. I can draw up a schematic for anybody that wants it, but I kinda just came up with it in my head. The module came with a small microphone, but I removed it and fed the signal directly from my PC soundcard for a clean signal. (used a 40dB pad to attenute the signal and not overdrive the module). It has two banks for two 20 second recordings. Anywho, I'll come up with info for anyone interested.
