9V AC to 50V DC Voltage Quadrupler Circuit
Like our previous post on Half Wave and Full Wave Voltage Doubler Circuit this article explains a full-wave voltage quadrupler power supply circuit; the circuit converts a low AC voltage into a high DC voltage. For example, it converts 9 V AC into approximately 50 V DC. Therefore, the circuit multiplies the input voltage by […]
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 and also there are […]
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; also 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 […]
3V Battery Operated Lamp Flasher Circuit
In this article, we explain a simple and easy 3V Battery-Operated Lamp Flasher Circuit that flashes a lamp using only a 3V power supply. Usually, low voltage flashing circuits give low output current, but however, this circuit gives high current output and therefore, it can drive a small lamp easily. The LM3909 IC forms the […]
One LED Low Voltage Flasher Circuit using IC LM3909
A low voltage indicator is essential for battery operated circuits because the battery can discharge at any time; therefore, a simple indicator helps monitor the battery voltage. Therefore, this One LED Low Voltage Flasher Circuit using the LM3909 IC uses only one LED, requires a minimal number of components and operates at a very low […]
