Nov-Dec 2012 - Anniversary Issue

As yet another year concludes, leaving many pleasant moments in the journey of our publication, we would like to rather concentrate on the achievements made during the short span of our existence in the competitive media space, precisely two years and more. Well, if any of you readers expect this issue to be a brag about our journey, or elaborating on the eventful year 2012 that passed by, you can seek solace with a word of assurance from me, that this issue is unlike the more commonly followed industry practices.

October 2012 - Energy Saving & Alternate Energy
Well, I begin with a crib to vent my heart out, accepting the face that having chosen the theme ‘Alternate Energy and Energy Saving ’ special, does exert emphasis to meet the most critical need of the hour.
Well, I begin with a crib to vent my heart out, accepting the face that having chosen the theme ‘Alternate Energy and Energy Saving ’ special, does exert emphasis to meet the most critical need of the hour. While posing challenges to meet the readers interests firstly, and enhance the enthusiasts experience by showcasing novel projects, news and electronic industry developments, we thrust our efforts in the Nation’s endeavor to save the world from energy crisis.

Audio DSP Course (4)
In the previous instalments of this series we have got to know the DSP as a specialist device for processing audio signals digitally.
In the previous instalments of this series we have got to know the DSP as a specialist device for processing audio signals digitally. We have also looked at software development environments and their functions and introduced the DSP board that accompanies this course. Now we will install the development software and test the hardware. We have a choice between a traditional development toolchain built from separate components, including two different debuggers, and an integrated development environment.

Clean Power from Hydrogen
Sustainable energy is what everyone wants nowadays, but what’s the best solution?
Sustainable energy is what everyone wants nowadays, but what’s the best solution? The options include storing energy in large batteries, hydroelectric power plants with water reservoirs, and hydrogen, but there’s still no clear answer to this question. Hydrogen appears to be a very promising candidate for mobile applications. Several car manufacturers already have prototype ‘hydrogen cars’ driving around, powered by fuel cells. Let’s have a look at what you can actually do with fuel cells.

DCC Command Station
Electronics is making more and more inroads into the domain of model trains.
Electronics is making more and more inroads into the domain of model trains. Trains are now controlled with digital codes, and in many cases the entire system can be operated from a computer. In this article we present a design for the device that forms the heart of a digitally controlled model railway: the DCC Command Station. The computing power in this design is provided by a high-performance ARM7 processor.

Economical Energy Harvesting
Alternative energy is a hot topic. In this article we describe several options for powering circuits from solar energy.
Alternative energy is a hot topic. In this article we describe several options for powering circuits from solar energy. As you can see, significant results can be achieved with a modest investment and a bit of sunlight. What’s more, once it works the power is free.In this article we show you several ways to power your circuits from an alternative energy source instead of batteries or the AC power grid. Here we focus on solar energy, but the methods described here can certainly be used with other energy sources as well.

Energy from the Internet, Water and ICs
Just because we play a minor role doesn’t mean that we don’t have an opinion on the subject of energy or sustainability. As always, if you’re part of the problem you’re also part of the solution. Here we present a small sampling of topics that we regard as ‘typical Elektor’.

Portable Energy
These days we all carry a whole array of portable devices along with us.
These days we all carry a whole array of portable devices along with us. Very handy, but those mobile phones and MP3 players have to be recharged frequently and a convenient power point is unfortunately not always at hand. Fortunately there are a multitude of alternative energy sources available, or so manufacturers have us believe...

2.4 GHz Antenna for Robotics Vehicles
Radio equipment using the license-free 2.4-GHz ISM (industrial/scientific/medical) band is also rife among robotics fans, just think of what you can do with Bluetooth, wireless cameras, remote control, or even a WLAN client or access point fitted on a robot vehicle!

Balancing Robot
The most famous balancing robot, also viewed from the general public's perspective, is the Segway, invented by Dean Kamen. This little cart on two wheels is a mode of transport for people, and these days adorns the streets of many large cities. The principle of balancing on two wheels has inspired many robot builders to the construction of such a robot. A few other examples are the NBOT built by D. Anderson and 'Joe le Pendule' built by co-workers at the Polytechnic School in Lausanne. This type of robot comprises a number of sensors and a drive circuit clustered around one or more microcontrollers..

Burn or Turn
Has your hard drive crashed? Don’t throw it away! You can still use it in many interesting projects. As an example, the author has used the read/write arm to make an alternative motor that is controlled via the PC.

Satnav for Robots
A (frequently unfulfilled) ambition of every robot builder is to make their machine capable of autonomous navigation. This is an ideal application for a GPS receiver module: these have recently become very cheap to buy. Our GPS-based navigation system is built around an ATmega32, programmed using BASCOM BASIC. It communicates with the outside world using an I2C bus...

Ultrasonic Distant Obstacle Detector

The first sensor a robot usually gets fitted with is an obstacle detector.

The first sensor a robot usually gets fitted with is an obstacle detector. It may take three different forms, depending on the type of obstacle you want to detect and also — indeed, above all — on the distance at which you want detection to take place.
