  • 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 […] […]
  • Simple Tone Generator using inverter logic form. April 16, 2014
    We use a simple oscillator circuit in very many projects. I like to use a inverter logic gate since it is easy and cheap. But we do not use it directly. Mostly I use IC4011 nand gates since includes for separate four positive logic nand gate on a single silicon chip. Enough for general use […] […]

    This circuit calls more Free Running Multivibrator work resemble Flip Flop. Which encourage itself repeatedly. The Q1 and Q2 be Transistor PNP be usable general (2N3906,2N2907, etc.) The R1 and R2 limit current that flow through LED the bilateral. If enhance the value C1 and C2 the rate something Flasher slow down. Request friends have […] […]
  • 220 volts power inverter using NE555 and MOSFET April 9, 2014
    Today I want to show you a 220 volts power inverter circuit. Which it is easy and small size. Because use NE555 and MOSFET as main. This circuit I experiment it work well,When use source is 12V battery will have output of 100 watts. The principle of circuit. I think many people does not like […] […]
