CuVoodoo #030 – audio is killing the music



building a sound level enforcer:
for a private club I built a sound level enforcer. if the DJ is playing music too loud, the device will shut off the audio output. for that I reversed a GM1351 sound level meter to extract the measurements from the LCD interface, send them over Bluetooth to the enforcer, which will cut the power to the main audio amplifier if a set threshold is exceeded for a couple a seconds.
