I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of the circuit is extraordinarily...

AC-Powered LED

Typically, an LED is powered by a DC supply; however, this circuit enables the LED to be powered by an AC supply. This circuit can serve as a power indicator for a water pump. The circuit for powering an LED using...

Flashing Led Controller

The LED with an integrated flasher is connected in series with the base-emitter junction of transistor T1. Consequently, the load connected to K2 is switched on and off in sync with the flash rate. This load can be a relay...

LED lights using Joule Thief circuits

It may seem that due to the numerous flashlight projects undertaken, there is a significant collection of lights. The inductor can be altered to set the current level, but the total current fluctuates with the battery supply, decreasing as the...

A passive light emitting diode output level indication circuit

A passive light-emitting diode output level indication circuit. This circuit utilizes a light-emitting diode (LED) to provide a visual indication of the output level from a given source. The design is characterized by its passive nature, meaning it does not require...
