DIY Microprocessor Sound Level Meter Demoed At MIT

Posted by timothy on from the you-only-listen-to-me-to-check-levels dept.

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!"

    ok so pretty cool, but can someone explain how hooking a mic up to an ADC is worthy of a mention for MIT? It sounds more like a high school project at face value, what am I missing?

    It IS a high school project at face value. The kit can be yours for only $80!

    Shouldn't ads like this be paid for?
