As an alternative to bipolar transistor, a lamp flasher can be built by using two power FETs. Like other flasher circuit, this circuit alternately switch the two lamps off and on. It is based on a simple astable multivibrator that formed by the two power FETs. To modify the flashing rate, just remember that flash rate is determined by the […]

This LED flasher circuit uses 555 IC, and is capable of driving up to 10 LEDs. The good news is, the use of multiple LEDs in series doesn’t increase the power consumption when compared with using only two LEDs. If we use only two LEDs, then we have to sink the power into a current limiter resistor, which dissipate the […]

This is flashing LED circuit emulate the turning of incandescent lamp. The characteristic of incandescent lamp is that they can’t abruptly change the luminosity. This circuit is used to fade in and fade out the on and off state change. Here is the schematic diagram of the circuit: The time constant of this fading is equal to the value of […]

This is the simplest circuit that mains powered light bulb to flash. To build this circuit we do not need a much money. This circuit can be used in small parties and similar occasions. This circuit is made by wiring a fluorescent lamp starter and a normal light bulb in series. So the light bulb will flash on and off […]
