This article discusses how to construct an effective inverter that uses an innovative chip called the IR2153 to convert 12V automobile battery power to 230V household current. Compared to previous designs this chip is superior because: Components required to construct this 500 watt inverter: Also anyone can adjust this inverters settings to reduce power consumption […]
Simple ESR Meter Circuit
This article explains how to construct a tool for monitoring capacitors in devices like phones and laptops. Similar to a small battery a capacitor is used to store power. One can identify defective capacitors without taking them out of the circuit board by using a device known as an ESR meter. To detect minute changes […]
Simple TV, Video Transmitter Circuit
Have anyone ever wished to construct its own small television station? This article is for hobbyists who want to make a simple transmitter to broadcast videos inside your house. The transmitter uses a special coil and capacitor to pick a channel between 37 and 50 on the old fashioned TV dial UHF band, 470 to 855 MHz. […]
220V Power Line Communication Remote Control Circuit
Our houses already use electricity to carry signals besides just power. This post shows how to build a remote control that uses the electricity in the walls of 220V to send signals. It works for short distances inside the house or apartment because the signal is at a much higher frequency 5 kHz than the […]
Simple FM Transmitter Circuit (100 meters range)
Is anyone Interested in starting its own little radio station? This post shows how to build a simple FM transmitter that works between 87.5 and 108 MHz on the FM dial. This transmitter uses a simple circuit with a special transistor and an antenna to broadcast your signal. It is different from other small transmitters because […]
Simple LED Strobe Light Circuit
This article teaches how to make a flashing LED strobe light using a popular chip known as the IC 555. A few knobs and resistors are used to control the lights brightness and flashing flow. Another resistor regulates the power supply that gets to the LEDs. This project makes use of a special switch that […]
