Cool!
Works exactly as described. Would make a few alterations;
-Screen flips when held with mic in the upright position
-Add a peak meter needle for sound spikes
-In appropriate font add some details to the body of the "unit", such as authors name, refresh rate, or other useful info.
-Perhaps an option to read in digital with a variable refresh rate?
