This is a fun, interesting. It can create the music enjoy listen to touch of a button to control metal. When our hands touch point. the Circuit will produces a musical sound by UM66T-IC1 out to peizo speaker immediately. This circuit use very little amount. Suitable for beginners. or Parents and children together to...

Normally in micro computer system will use a crystal as frequency generator. Although now the crystal will be cheap down. But then still is an expensive components,when compared to other devices. And I like to modify the electronic devices that remove from the old PCB to reused always. Because it enables us to save....

  • How to make simple electronic buzzer April 21, 2014
    A electronic buzzer is simple. But useful well worth and the price is lower than 1$. By use just a 9-volts battery only. So without worrying about electrical leakage or electric shock from 220V to buzzer. Unless also has LED will glow. Show that the circuit the normal operation as well. The working of circuit. […] […]

  • Automatic night light switch using 741 op-amp. April 21, 2014
    We’ve watched a lot of Automatic night light switch circuits. Which I like to use a transistor as base. But now we lets to see IC-op-amp. It is also very simple. As my feelings It has high sensitivity more than one, and with great high accuracy. How does it works. A light detector component, we […] […]

  • Morning alarm with sunlight using IC-4011 April 17, 2014
    This is simple circuit that we makes in hobby time or toys for my son but really uses. It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock. We use a IC-4011 CMOS only one and a few components also can generate pulsating tone like a general clock. […] […]

  • Simple Electronic clock sound using IC4011 April 17, 2014
    The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can assemble on a breadboard right […] […]
