Random Doorbell (KIT35S)

R138.00

The Random Doorbell plays more than one billion (one thousand million) tunes, delivering a powerful 2 Watts RMS into 8 Ohms. It could easily be adapted as an intruder alarm siren.

The Random Doorbell strikes a balance between playing too many notes at too fast a tempo (which would approach white noise) and playing too few notes at too slow a tempo (which would tend towards monotony). This balance is fixed in the component values.


Items NOT included in the kit, but available separately, are:
Regulated Power Supply, 12V dc.
Mylar Cone Loudspeaker, AMA00T or BCN10G.
