Music Box - This circuit produces 10 different tones and by selecting
suitable values to change the voltage on pin 5, the result can be quite pleasing.
Note: the two unused outputs of the 4017 produce a tone equal to that produced by the
555 when pin 5 has no external control voltage. |
|
Music Box - This little novelty uses the PIC PWM output to produce an
approximation to decaying sine waves, which sound very much better than fixed
amplitude square waves, but its still far from precision function generation!! An LDR
provides a simple way to detect when the lid of the music box is opened. Alternatively
of course, pin 13 (RB7) can be tied low and a microswitch employed on the power
rail....(added 04/04/04) |

Music On-Hold for Telephones - .... |
|
Music to light modulator - The diagram shows how simple the circuit is. The
audio signal is applied across the LED of the opto-triac. The potentiometer adjusts
the input sensitivity while the resistor is used as protection from high signal
peaks…. (Circuit design added 07/07/07) |

Musical ‘Touch’ Bell - .... |
|
Musical Horn for ATBs - If you are both an all-terrain biker and handy with
a soldering iron, then we suggest you build this musical horn which, apart from the
fact of having a much pleasanter sound than a simple bell, will usually make
passers-by turn to you with a broad smile, so surprised will they be to hear these few
notes coming from an ATB or mountain-bike….must register on this site.... [Published
