Power management in portable devices is one of the toughest challenges faced by electronic engineers. The consumer demands instant response from their device, lots of functionality, and a large, bright and colorful touchscreen. Moreover, many of these portable devices now incorporate wireless connectivity that places further demand on the cell. And yet, the user expects […]

Researchers at Scandinavian research organization SINTEF have made progress in developing components that dissolve in water. Printed on a silicon wafer, the components contain extremely thin circuits — only a few nanometers thick — that are designed to transfer energy. They are made of a combination of magnesium, silicon, or silicon with a magnesium additive;
Eco-friendly electronics of the future will be designed to disappear Continue Reading
Software simulator for Electronic Assembly display EA DOG series will bring you a clear image about possibilities of this favorite series. Usually, when we start working with some monochromatic display with a color backlight, we have to imagine which combination of display/ backlight would suit us the best. It isn´t hard but for sure even

Switch-mode regulator Traco TSR 0.5 will give you as much as you need. If you have an application, where 0.5A is sufficient, then the new series of DC/DC modules is ideal for you. Maybe, it´s worth to ask a question, whether it makes sense to use a switch-mode regulator for such a low current? For
Why to pay for the current, which you won´t use? Continue Reading
Hello guys! In this instructable I’ll teach you how to make a very simple proximity sensor using infrared LEDs and Arduino. After several times trying to optimize it, I finally came up with something that is quite simple e precise. Just like my first instructable, this project is perfect for beginners in the arduino’s world, with
Simple IR proximity sensor with Arduino Continue Reading
Some members of the family of mid-power LEDs Osram Duris were introduced to you a year ago in the article A light without an end with OSRAM Duris E3 and E5 LEDs. So far, these basic series were available: Duris E3 – white LEDs LED 3×1.4 mm with a max. current of 30 mA in
Duris S5 – the best of the Osram Duris white LEDs family Continue Reading
My two and a half year old son loves toys with flashing lights. For this Christmas I thought of making a mini LED Christmas tree for him. This project uses 22 multi-color LEDs which are driven by a PIC12F683 microcontroller using the Charlieplexing technique. The details of the build procedure is described in the following

There are many producers of wires, leads and cables, but despite it, company LappKabel belongs to one of the most renowned. What´s the cause? Exceptional place on the market started in 50-s, when company LappKabel started as the first in this segment to name its products (Olflex). Together with high and stable quality, LappKabel has
If a cable, then the Lapp cable Continue Reading
Rohde & Schwarz designed the new 200 MHz models of the R&S RTM oscilloscope especially for universities and educational institutions. The education mode was developed for test and measurement practica and makes it possible to disable all analysis tools (e.g. Autoset and QuickMeas) and automatic measurements. This improves the learning effect as students and learners
