I was wondering if I could save the audio information in the sketch, using "hoffman code?"
An sd card seems like a waste for one file.
Interesting project, at least as an end in itself. Seems I've seem small "toy" voice recorders for a few bucks that will record at least for several seconds.
for instance there are somethings on here that aren't labeled:http://elm-chan.org/works/sd8p/rc/sd8p_mo.png
where do i find the pinout for the SD card?
like it only uses the 104 Cap
