Working together with our intern, the Sound Amplitude Measurement device was made. Guts include a PIC16F873A, servo motor for the dial, active filter at 1.5Hz based on an opamp and RGB lighting inside the head. This is the first thing I've ever had to stuff (%100 polyester fiberfill) and I found it oddly soothing to staple swathes of puffy stuff to the MDF framework inside.
