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 frequency of IC1, set by […]
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 Inverter 100W by IC 4047 […]
