Soldering irons

A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces. For well over 4000 years mankind has known how to join metals together by soldering. In the 1800s and early 1900s soldering irons were still heated by flame.

Function generator kit

A function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine, square, triangular and sawtooth shapes. Function generators are used in the development, test and repair

GIMP the Free and Open Source, cross-platform image editor available for GNU/Linux, OS X, Windows and more. GIMP provides the tools needed for high quality image manipulation. Open source software GNU Manifesto turned 30 years on spring. Also GIMP celebrates round years: 20 Years of GIMP. November 21st 1995, few days over 20 years ago

KiCad video series: from concept to manufacture

Many electronics hackers have habit of using Eagle to design their PCBs. You’ll find plenty of support for this software as well as a lot of parts libraries, the free version of Eagle software comes with limitations (board area is limited to 4×3.2 inches, only two signal layers and the schematics editor can only create

Interesting signal generators

Function generator in an important tool in electronics laboratory. It allows to generate different types of electrical waveforms over a wide range of frequencies. Traditionally function generators have been built using analogue electronics. There have been special ICs that have been widely used for this: Exar XR2206 and the Intersil ICL8038integrated circuits can generate sine,
