Power adaptors are devices that change the current electricity, from AC power to DC power, since not all appliances have the same power needs. AC is for alternating current while DC is for direct current.

People are fascinated by light. I mean, just glancing over at a display of flashing lights can grab my attention. Do you ever remember sitting around a camp fire, staring at the flames and being just totally transfixed almost like if you are watching TV? It’s comforting and it could even be hypnotic. Recently, technology has made creating light a whole lot easier to do. For that, we have this little guy to thank. The light emitting diode or the LED for short.

Stripping wire is tedious and nobody likes to do it. But if you are going to get started in electronics, you might as well learn how to do it right and save yourself some time and frustration.

Target of this article is to understand some signals of Playstation 2.

This video is extremely interesting, since energy saving is an hot topic.

The most used LCD is the 16x2 (i.e. 16 chars per row, two rows). You need to know the lcd controller to interface the LCD to your electronics (usually a microcontroller) and most of the time 16x2 lcds use an Hitachi HD44780.

This is a very simple circuit, since LM3914 is all you need. Adjust the voltage divider and add some leds, that's all folks!

Today we are gonna talk about LCDs and GPS. Let’s get started with the LCDs and then GPS.

Driving stepper motors with Arduino and L297 (datasheet)! Arduino is well known for its simplicity of use, in a short time it is possible to make new projects.

Dr.Heinz Schmidt-Walter made life easy for many switching power supply designers, by making available on his web site a procedure to compute parameters of the most important switching power supplies.
