we are selling out the last of our MICrODEC's at below cost. it is an arduino compatible (atmega3250p) platform for doing audio processing. it has a stereo, 16b, 44ksps codec, and 6 seconds of sample memory. there is also a case, while they last.
some soldering is required, and you will also need an FTDI cable to program it. there is a very basic library written for it, but it is geared more at advanced arduino users. we have a few of these left in stock, and are looking to get them out to good homes.
