Today, in advanced world electronic touch switches are becoming very popular. They replace mechanical switches and therefore, there is no moving part, so its life is longer. This Touch ON OFF Switch Circuit using IC 555 Timer works as a bistable multivibrator. When we touch the touch point the output changes its state, that means […]
AC to DC Bridge Voltage Doubler Power Supply Circuit
AC to DC Bridge Voltage Doubler is simple power supply circuit. It is used to get higher DC voltage from low AC voltage, for example from 9V AC we can get near 18V to 25V DC. Therefore, it is useful when we need high voltage but transformer gives low voltage. Also, this circuit is with […]
9V AC to 38V DC Voltage Tripler Circuit
This project is for simple 9V AC to 38V DC Voltage Tripler Circuit and it converts low AC voltage into higher DC voltage. The input is 9V AC from transformer and the output is around 38V DC without load. It is easy to build as it uses common parts and therefore, it is good for […]
9V AC to 50V DC Voltage Quadrupler Circuit
Like our previous post on Half Wave and Full Wave Voltage Doubler Circuit this post is about a full-wave voltage quadrupler power supply circuit. It converts low AC voltage into high DC voltage for example, 9V AC is converted into approximately 50V DC. Therefore, it multiplies the input voltage almost four times, so it is […]
Half Wave and Full Wave Voltage Doubler Circuit
In many electronic projects, we need a higher DC voltage, but sometimes transformer gives low AC voltage. For example, a 9V AC transformer is common, therefore, we use voltage doubler circuit and this increases voltage without using high voltage transformer. Besides increasing the voltage, this circuit also converts AC into DC. There are two types […]
Random LED Number Generator Circuit
This circuit is for simple Random LED Number Generator Circuit using IC CD4017 decade counter and IC CD4011 NAND gate. It works on 9V power supply and the LEDs in the circuit represent the numbers. When we press the switch, one LED remains ON, because the counter runs very fast and the final LED looks […]
