Some people can really spoil your enjoyment
of TV by constantly messing about with the
remote control. This device will alert them
with sounds that this goes on your nerves.

The TV friend
Every time a button of the remote control is
pressed, a sound you can select yourself is
played in response. The construction requires
the light sensor and the loudspeaker. The
programme is started again with two wire
connections, A-B and C-F.
It should not be very bright so that the remote
control can be detected properly. Your
device may have to be placed in the shade
but you need to ensure that it can still »see«
the remote control. Test the function with any
button of the remote control. As long as the
TV is off, you can use the volume buttons
for the test. You will hear the familiar call of
the cockerel. You can try other sounds by
connecting the positive cable to the inputs
MI2 to MI5.
