When we say to the an astable multivibrator circuit, Many people will think to Many people think of as the most IC-555. But this time, it is recommended circuit in Figure 1. Which use IC-4047 CMOS with ability of this nature as well. And the advantage is, That output will… Read more »
This is a small AC inverter. There are very small amounts. For the experimental study. Because low power of around less than a 60 watt only. However, you still can get a good basic circuit course. This circuit we use an IC-4047 as astable/monostable multivibrator that low power is main… Read more »
The 12 volts of Car battery and converted to AC 220V 60 watt. Then apply to appliances easily. And portability easy with Because of the small. In circuit we use CD4047 and BD249 as main part so is mini circuit. The working principle. When we connect the 12 volts in… Read more »
This is a small circuit insect repellent, mosquitoes and birds, or other methods to produce high frequency audio signals. To interfere with the hearing of insects. Make it insufferable, wings to escape in the end. Operation of this circuit is used IC1 number 4047. A duty to produce frequency. The… Read more »
This is inverter 100W circuit, use IC 4047 alike inverter 100W transistor I use Mosfet IRF540 instead Transistor 2N3055. It good Idae, power output 100W from transformer 2-3A. Read detail more in circuit.
This circuit power Inverter 100W, so input voltage 12V (battery 12V) to output volt 220V ac 50HZ, it is asy circuit because less component to use. It use IC CD4047 Squarewave Oscillator 50HZ and Power Transistor 2N3055 x 2 For driver transformer 220V ac to OUTPUT Power 100W min. Circuit… Read more »
