I have to build a project at the end of the semester for an electronic circuits class and I thought I'd build my own sound card. Any schematics floating around out there? I did find http://diy4fun.blogspot.com/2010/01/...h-pcm2704.html this nifty little guy, but I'd want to wire it to run off batteries instead of USB and then how do I "save" the sound? I guess I want something like http://soundexpressiongreetings.com/...d-modules.html but I don't know how to build that -- any schematics for something like that floating around? I guess what I really want is something like a battery recharge port? I want to be able to connect it to my computer, save sound to the card, then unplug it from my computer and have it keep playing the sound. I have a USB headset and I was thinking that something like this: http://www.techradar.com/us/news/com...undcard-679211 would plug into my computer, then I could run a headphone jack cord from that and plug that into the hilt-based sound card. Again, though, I have no idea how to even start building something like that, but I do have to build some sort of final project for the class. Any suggestions?
