Song Music generator circuit using ic UM66
This is a simple (song) music generator circuit using ic UM66. To make a musical calling-bell, door-bell, kids toys etc. we can use this funny audio/sound/music/tone generator ic UM66. The UM66 series are CMOS IC’s, they has a built in ROM to store the music. The IC operates in DC +3V. We suggest to use two dry cell (1.5V X 2) for +3V Supply. For Q1 use a TO-92 type NPN transistor like BC548, BC168, BC183, BC238, 2N2222. Speaker must be 4Ω or higher.

UM66TXX series IC generate different songs-music, the song-music depends on the model of UM66TXX series IC’s. The song-music are listed below with model number.
UM66TXX Songs List:
UM66T01 = Jingle Bells + Santa Claus is coming to town + Wish you a Merry Xmas
UM66T02 = Jingle Bells
UM66T04 = Jingle Bells + Rudolph, the red-nosed reindeer + Joy the world
UM66T05 = Home sweet home
UM66T06 = Let me call you sweetheart
UM66T08 = Happy birthday to you
UM66T09 = Wedding march
UM66T11 = Love me tender, Love me true
UM66T13 = Easter parade
UM66T19 = For Elise
UM66T32 = Waltz
UM66T33 = Mary had a little lamb
UM66T34 = The train is running fast
UM66T68 = Its small world

Luggage Protector Circuit Using 555 Timer IC
The circuit is called protector alarm circuit to protect from the theft of your luggage or bags. This circuit is built electronically using 555 timer
IC. The alarm will rise highly when the thin wire is cut off by the
thief. The circuit configuration using 555 timer IC acts as a astable multivibrator which produce signal tone of frequency of about 1 KHz and produce sound like a shrill noise away the output speaker.

IC’s
5number pin is directly connected to the power supply. 10k, 68k
resistor and 0.01uf capacitor are connected to generate specific range of frequency
like as 1KHz. You can change output frequency by changing the value of
resistor and capacitor. Pin 1 is directly connected to the ground.
Output is taken from pin 3. A 8Ohms speaker is connected to the output
for alarm sound. Thin wire is connected as shown in figure.

The
wire would be very thin copper like 36 SWG or higher. You can use one
gage of normal wire. The driving voltage of the circuit is 5 Volt to 12
Volt.

0 4W power amplifier with 5G37 IC
This circuit requires a voltage of 6-12 Volts. To have a good quality of this series with the voltage necessary suplly good too. The definition of good that is filtered and does not release much ripple voltage and using large-capacity condenser elco issued for the bass is strong enough.
See below this circuit :

Datasheet IC 5G31A
Vcc = 6-12 V
Pout = 0,4 W
RL = 8 Ohm
Ft = 40-17 Khz
Icco = 15 mA
Package = TABS1-14
Manufactered = China
