Google searching for audio recording results in a number of cases where USB sound modules are working well. To all: This is a cost-sensitive deployment. University of Toronto has HUNDREDS (if not over a thousand) of very active lecture rooms on a very very large campus. Deploying a laptop that costs a few hundred dollars at minimum to each of them is not practical. In addition, laptops aren't designed to be run continuously for years for many reasons. A full Raspberry Pi system with equivalent capability as a laptop for this application can be set up in well under $100, including a small composite screen. Much cheaper if a serial LCD display is used, which is sufficient for the application as well. In contrast, netbook from a reliable source will cost AT LEAST $300, in addition to problems with heat/dust buildup/fan/hard drive failures etc. SSDs will be more expensive and further cost prohibitive. There's just much less to go wrong with a Raspberry Pi/plug computer. Also, the university is quite stingy for funding projects, so I have to consider the possibility of getting funding from the student's union, which means funding will be far more limited. Again, another major hardware component is the analog line splitter which can't be ignored regardless of the type of computer used. I'd rather keep the option of using a raw digital IO from the RPi for various purposes like controlling the line splitter, rather than buy extra modules to provide basic IO from a laptop. Adding USB to everything unnecessarily is another cost issue that I can avoid by using the RPi. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
