DIY Microprocessor Sound Level Meter Demoed At MIT 81
An anonymous reader writes "A Piezoelectric Sound Level Meter was demoed at MIT's Battle of the Bands last month, borrowing its display from the do-it-yourself USB LED marquee that was the subject of a previous Slashdot story. This video tutorial describes in detail both the analog electronics plus the C code that runs the system. If this is your first experience at the intersection of digital and analog systems, don't be scared!"

I completely agree. This is a trivial piece of hardware, of which there are millions of examples on the Internet, the majority of which are more interesting than this.
Is this of interest just because someone at MIT was involved? What's next? MIT engineers demonstrate how to drink beer?
