The previous day my son said ” A friend has a mini organ. Casio SA-76 44 Key Mini Keyboard, Orange It is Good quality but expensive. My son would have the same. But I said, as we are the Electronic inventor, to try to create their own. We are proud and cheaper too. You might like this mini organ keyboard circuit certainly. Because in addition to the simple, the price is not expensive, effective really worthwhile. You may consider the main features of the circuit, as follows. 1. Can works with DC voltage in rang 3-12 Volt by low current consumption. 2. There are the music playback up to 15 keys, or a note from G3-G5. 3. Can be programmed to play. Repeat for up to 47 notes. 4. Can act as a music source by up to 15 songs.(Simple carbohydrates. Press any key. To select the desired song.) How [...]

You will never be bored Simple melody generator circuits. They are very useful for adding color to various electronic projects. Let’s say you build a sound the alarm in the morning with their children. If you use siren to warn children not appropriate. Make him was shocked. Try changing the sound of music. Helps to hear more. Normally we use the IC circuit. Because it is convenient and small. CIC2850 is IC that evolve from CIC2813. Designed to least external devices, are only a resistor and a transistor. Common features. 1.Applied to voltage range of 1.3 – 5 volts. 2. There are 64 note memory. 3. They can stop automatically. 4. Can repeat forever. The introduction of the song, it always starts from the first note. There is tempo to choice of 5 strokes. The CIC2850-IC is a 9 pin form inside IC consists of various circuits as show in [...]

This is the Melody and Music tone generator circuit which I think is useful for adding color in the electronic work is good, Can be applied to sound an alarm, or assembly electronic projects very well. Examples circuit that I suggest, is a switch for adjusting the sound more, it is not boring, these circuits are suitable for the toys in time for the children, or parents who want to add electronics skills to children. Western music using ic HT82207 Sounds that you heard in the movie, which is fighting the cowboy, the gun sounds, sound horse this cycle is to be born.Because the IC has already been programmed to be easy to use. Principle of the circuit is.When the circuit to the power supply. Then try pressing the switch S1 will allow the production of IC1 frequency out of pin 17. In addition to Q1 amplifier IC1 is often [...]

Near the Festival of Happiness.Christmas and New Year’s Day. My son was thrilled with the gift of friends in the village.Music Box is a scientific inventions that he wanted made because he thought it would impress the recipient. And it is easy made electronic projects. Cheap as well. I suggest three circuits, which featured various By the application of each person. Music box versatile using IC M3481 This is a multi-purpose integrated music box that interesting, because an IC package. Is a simple and affordable. The main function of the circuit is the device of the circuit is IC1. This is a sound generator IC. The Christmas season. Its musical all 8 music. When the power supply LDR1 the exposure will cause voltage drop across R1 is enough to make IC1 work has output to stimulate pin 11 and pin 12 to stimulate pin B of Q1. Q2 and the [...]

In this high-tech generation, the style of music, inevitably have a profound exotic. And harmonic rhythm techniques with much more satisfied than before. Which this small electronic drum project is Instrument of this era really, It can be applied to the various sound effects and many others. How it works. Main idea, we use a loudspeaker instead a Microphone. Knock on the front of the speaker, makes speaker cone to vibrate, causing a small electrical signal up. This signal was amplified and stronger and is converted to DC, to control the production of frequency circuit, and this frequency which it is mixed with the signal from the beginning, and then output to the amplifier. Sensitivity control As shown the circuit 1 is a complete circuit. When you tap the speaker causes the electrical signal, by the knocking. Through C1 and VR1, to the amplifier by IC1 pin 3. Which, VR1 [...]
