[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

A self-biasing thermistor circuithad an overall dominant thermal/electrical time constant as small as25 msec but had a significantly roundedresponse following a square (thermal)input pulse of 100 msec ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...

This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

The design of luminaires for solid-state lighting is still part black art. The best approach starts with the light output and an artistic arrangement of LEDs. So, your company has decided that it has ...

Description: LED Blinker is an Android app that aims to make it much easier to help you figure out which notification is which. Using the LED light on your Android device, you can choose from a range ...
