DEVICES OF PERCEPTION
ASSIGNEMENT N° 1 - LOUDNESS KILL SWITCH
MONOSTABLE 555 - MOMENTARY SWITCH
The "Loudness Kill Switch" reacts to the loudness of music emmited from a speaker. The mechanical construction consists of an aluminium ball applied to a loudspeaker, moving towards a copper rod when music is played. The circuit will be closed if the aluminium ball gets in contact with the copper rod.
That happening a LED will light up and the loudspeaker (connected to an amplifier again connected to a solid state relay) will turn off for ca. 30 seconds. This time passed the loudspeaker will turn on as the LED will turn off again.
To improve: The circuit will only be closed if there is enough base in the music.
You will need: 1x Styrofoam ball wrapped with aluminium foil | Copper rod | 555 Timer | Solid State Relay | Loudspeaker | Amplifier
