A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

Transmitting information using light is more energy efficient than using electrical signals. Unfortunately, for small-scale applications, light-based encoding through electro-optic modulators (EOMs) ...

In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...

Automotive integrated circuits (ICs) are the critical drivers behind modern vehicle automation, safety, and efficiency. As electronic systems in automobiles become increasingly complex, robust testing ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

Here is an interesting circuit of a true-portable and cute solid-state bright light built with LT1932. The light can be operated from two AA size dry/rechargeable pen-light cells. There is no housing ...

Siemens Digital Industries Software has introduced Tessent AnalogTest software – a solution that looks to reduce pattern generation time for analogue circuit tests from months to just a matter of days ...

Mercedes-Benz has taken its testing game up a notch at the Global Proving Ground in Immendingen, Germany, with the addition of a cutting-edge light testing centre and an automated durability circuit.
