This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

This circuit was designed to provide that continuous light lamps already wired into a circuit, become flashing. Simply insert the circuit between existing lamp and negative supply. Especially suited ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a flashing LED was something of ...

Everything was going fine until we got the LEDs installed and went to test the turn signals in the driveway. Nothing-no blinking, no flashing, no nothin'. Perplexed, we retraced our steps, ...

[Tito] entered a Self-Charging LED Flasher into the Component Abuse Challenge. It’s a simple re-build of a design by the unstoppable [Burkhard Kainka], and while [Tito] doesn’t explain its workings in ...

Experience low power, high security, and reliable performance with PolarFire® Core & SoC FPGAs. A maker recently engineered ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

A recent design project required a bright LED flash each time a 100-µs pulse occurred. The pulse repeated every 300 ms. Because the pulse was so short, driving the ...
