10 CAN Tester
     The circuit described here has all the features required for conducting

     various experiments and tests on a CAN bus. In addition there is the option

     Elektorof connecting the tester to an existing CAN bus to monitor the data or to

     track down faults.
18 Elektor Linux Board: New and Improved!
     The compact and low-cost Elektor Embedded Linux board has been

     available to buy for around a year and a half now. Along with its

     accompanying series of articles it offers even beginners access to the world

     of embedded Linux. It is now time for us to update the board based on

     feedback from the user community. To begin with let's add LAN and RTC.
22 Important Update to the Elektor 500 ppm LCR Meter
     Here we correct two shortcomings liable to interfere with proper operation of

     the instrument: occasional hang-ups and issues with the Trim actions.
Elektor26 Multichannel
Temperature Logger
     This project allows you to log up to six temperature readings over a period of

     time, complete with time stamps, all written to a .csv file stored on an SD

     card for processing on a PC. Local control is also available in the form of an

     LCD and a keypad.
Elektor32 USB Thermometer
     When you need to hook up some electronics to an RS-232-less computer,

     the USB port looks like the only option. The computer however needs a

     corresponding software driver. Here we describe an elegant patch around

     this problem.
42 Bidirectional
     eStereo Input Selector
     Following a recent appeal made in the magazine calling on our readers to

     send us their own circuit designs—if possible simple and preferably in fields

     that receive less coverage in Elektor, like audio, for example—we received

     this suggestion which meets the two main criteria: uncomplicated and

     intended for processing sound signals.
46 LED Lighting for Model Buildings
     This small module has been designed to individually control five LEDs used

     to illuminate model buildings. The control signal is sent over a single wire

     from a PC's RS232 serial port. The design allows for up to 250 modules to

     be controlled by a single PC, that's almost enough for a small town!

Elektor38 DesignSpark Tip & Tricks, Day #5: generating PCB

     manufacturing files
     Today we will generate the Gerber files and BOM information for the design

     we laid out last time. DesignSpark has excellent support for generating

     these types of files once it's been configured properly.
Labs
50 .Labs Tips & Tricks
     This month we present a selection of projects posted on Elektor.Labs and

     looking for a helping hand to reach the finish line. Can you cheer and/or

     assist?
52 Standards for Coding
     eOften a lot of time and energy is spent on designing an elegant,

     well-thought-out and robust circuit. Today, the brains of many of those

     circuits is a microcontroller that needs software to function. Is it

     unreasonable then to expect a well-designed, properly written program to

     make such a quality circuit work? Apparently it is. Let's talk software quality.
58 Keep The Pins Afloat
     Forget to tick a few boxes and your entire FPGA project fails to work, as our

     lab workers found out the hard way.
60 PCB Prototyper Master Class
     Here's a how-to on an advanced application of the Elektor PCB Prototyper

     milling machine.
Tech The Future
Elektor68  Forze VI:
      A Hydrogen-Powered Racecar
     The Forze VI weighs just under 2,000 lbs., achieves a top speed of 138 mph,

     and accelerates from 0 to 60 mph in 4 seconds. The heart of the racecar is

     the fuel cell system.

Обработанные водным раствором щелочи стальные контакты (например, батарейного отсека переносной магнитолы или пульта ДУ) никогда не заржавеют.
