You meet them every day without knowing that those are Friwo. However world-class producers know why they use them…
Friwo power supplies guarantee top-level specification and reliability, what can help you to gain and keep customers and a good reputation. To have a trust of customers is usually the most important factor influencing whether you will sell your product or not. And trust of customers is usually built on a reliability of a device…
Nowadays, when a device with almost the same functionality can be bought from several producers, the success or fail on the market is in the hands of seeming trifles. Naturally, there´s often a pressure on a very low price, but hand in hand with this requirement, everyone also wants a reliability.
Designers of electronic devices know, that a device with the same functionality can be designed in two basic ways:
1) in a way that it worked on the edge of its possibilities (weakly dimensioned components, slower semiconductors with higher losses, …). Such a device operates at “usual circumstances” properly, only maybe generating a little more heat (lower efficiency). The problem is usually a lower lifetime and a much higher susceptibility to overvoltages in mains line, disturbances, higher or very low temperatures etc.
2) or in a way that it worked with a reserve even in not always ideal conditions (temperature, voltage spikes, ….) even for a price of slightly higher production costs.
It´s obvious, that a device designed by a “pattern no. 2” provides far higher assumption of a reliable operation without claims, service events or a loss of a good reputation. Friwo as the biggest and the only European producer of power supplies in a given range wagered on quality and no wonder, that it´s the first choice of many renowned producers like Bosch, Metabo, Makita, Braun, Siemens medical, Porsche, Geberit, Sagem,…. If you didn´t meet a mark Friwo yet, it may be because Friwo is first of all the OEM producer and almost everyone of us daily uses some product with a Friwo power supply, without knowing it.
On stock we keep a selected range of adapters, but much more important is the fact, that we´re able to provide you any power supply from Friwo and upon order it´s also possible to produce a power supply exactly according to your demands. Friwo disposes with many production capacities, like laser trimming enabling a flexible adjustment of specification. An image about the Friwo power supplies will give you the document Friwo company profile as well as our article „Your devices will fall in love with premium power supplies Friwo”.

The MAX31740 is a sophisticated, yet easy-to-use fan-speed controller. It monitors the temperature of an external NTC thermistor and generates a PWM signal that can be used to control the speed of a 2-, 3-, or 4-wire fan. The fan control characteristics are set using external resistors, thereby eliminating the need for an external microcontroller. Controllable characteristics include the starting temperature for fan control, PWM frequency, fan speed at low temperatures, and slope of the temperature-duty-cycle transfer function.

Intel® Galileo – Intel® Galileo is the first in a line of Arduino-compatible development boards based on Intel architecture.
Galileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip. It is the first board based on Intel® architecture designed to behardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3.
Now there is an Intel based Arduino – Intel Galileo - [Link]

This little project will demonstrate how you can build NEC protocol based Infrared Remote Control to use with various NEC Protocol IR receivers. actually there are lots of projects out there to accomplish this task but i have to write my own code because of too many requests on this IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller people keep asking “Where is the Transmitter for this” although you can use any NEC protocol based remote ,but i just wanted to build one by my self. so here it is.

This tutorial is an introductory tutorial on getting started with the MSP430 series of controllers by Texas Instruments. muaz @ zeroohm.ae writes:
There are millions and trillions of ways to start using microcontrollers. Hobbyist or people who find hard to code normally prefers Arduino as their coding environment, while engineers might prefer using AVR/PIC. The MSP430 microcontroller is an extremely versatile platform which supports many applications. With its ability to consume ultra-low power it enables the designing engineer to meet the goals of many projects. It has, of course, its limitations. It is inclined mostly towards low energy and less intensive applications that operate with batteries, so processing capabilities and memory, among other things, are limited. However it’s still called a mixed-signal processor and is capable of doing some sort of speech processing. Before starting with some exposure to hardware and software part, I assume that you all have some sort of programming knowledge in embedded c. Even if you know java or c++, you will still be able to adapt to the tutorials easily as the logic will remain the same, only the code language changes.

I’ve been working on re-making the the Open Hardware Pulse Sensor so it’d be “easy” to send off to OSHPark and make at home. I’m not sure but I think I started this project in March (2013) and I’ve just now finished it.

jechavarria build a breakout board for the SIM900 GSM module. He writes:
Hi! I want to share with you my last design. It’s a breakout board for the SIM900 GSM module. Fits in a 50×50 mm board, and has an IO connector with many of the signals you need to control it. Also, as the board is designed to work with a battery, it also includes all the necessary components to charge and manage it. The internal power supply is 3.0V, so external controller must be work at this voltage. Here’re a couple of photos of the board
