Get Inspired: Opportunity... written by Berton Braley

     With doubt and dismay you are smitten
        You think there's no chance for you, son?
    Why, the best books haven't been written
        The best race hasn't been run,
    The best score hasn't been made yet,
        The best song hasn't been sung,
    The best tune hasn't been played yet,
        Cheer up, for the world is young!


    No chance? Why the world is just eager
        For things that you ought to create.
    Its store of true wealth is still meager
        Its needs are incessant and great,
    It yearns for more power and beauty
        More laughter and love and romance,
    More loyalty, labor and duty,
        No chance--why there's nothing but chance!


    For the best verse hasn't been rhymed yet,
        The best house hasn't been planned,
    The highest peak hasn't been climbed yet,
        The mightiest rivers aren't spanned,
    Don't worry and fret, faint hearted,
        The chances have just begun,
    For the Best jobs haven't been started,
        The Best work hasn't been done.

Evoulation of Radio Astronomy: The Complete Story.

The age of radio astronomy began from the day when engineers learned to generate radio waves using an electron tube. Approximately after a decade from the discovery two young and dynamic engineers Gregory Breit and Merle Tuve, bounced radio waves off the ionosphere and determined the height of the layers. This proved that radio waves can travel beyond earth and back and they can be used as a probe for communication. 


Two years later a well known American inventor, writer, and magazine publisher Hugo Gernsback popularly known as father of science friction proposed an article "Can We Radio The Planets". The radio waves that can be bounced from the moon and the planets. He also stated that 2.5sec will be required for a radio wave to travel to the moon and back.



In the years of 1930 Karl Guthe Jansky at Bell Telephone Laboratories investigated the noise sources in radio transmission. Jansky used a large directional antenna of 14.6m wavelength which identified three different types of static noise. Noise signal from local thunderstorms, a steadier (ie; firm in position) and weaker static from distant thunderstorm and a weak hiss from unknown source. 

The weak signal from the unknown origin peaked about every 24 hours. Firstly Jansky suspected that this unknown source was sun crossing the view of his directional antenna, but when Jansky compared his observations with the optical astronomical maps, he concluded that the radiation was coming from the Milky Way and it was maximum in the direction of center of galaxy.

But instead of encouraging the research of Jansky; Bell's laboratory rejected Jansky's request to build a 100 foot radio telescope. No other institution followed Jansky's work.

Only after World War II a radio engineer Grote Reber took Jansky's work and continued it as a hobby in his spare time. He built a 31-foot parabolic antenna and in 1937 made the first radio map of the sky. With the intense development of radar technology during the world War II gave a new aid to astronomers. 
 
A team headed by J.H. De Witt of U.S. Army Signal Corps were succeeded in seeing the echoes of the moon on the cathode ray tube .
From then there was no turning back and in the years of 1940-50 radio astronomy emerged as a new branch of astronomy. A 76m steerable radio telescope was built in England at Jodrell bank in 1957. 


While a 305 meter fixed reflector was completed in Arecibo Puerto Rico in 1963. It is the world's largest radio telescope made till date.

Designing a Simple Touch Sensor.

With the development of touch sensors new horizon of sophisticated devices evolved with reduced mechanical parts. This was advantageous in many ways because the weight, size, space requirement and ultimately cost reduced. But before putting this concept into an application, you should be first familiar with the printed design considerations. This post will help you in designing a Simple Capacitor Touch Sensor.

A simple capacitor stores energy between its two conductor plates which are separated by dielectric. But some of energy manages to spill over outside the plate area. This electric field lines are called fringing fields. The concept is to direct this fringing  field into an active sensing area accessible to user.

So the question arises how can this be done? This can be achieved by simply placing a finger near the fringing field which will add conductivity to the surface area of the capacitive system. "Wondering How?" 

The tissue of human body is filled with conductive electrolytes, covered by a layer of skin 'a lossy dielectric.' The conductive property of finger makes capacitive touch sensing possible. the additional charge storage capacity added by the finger is known as finger capacitance.

The fig shows a simple capacitive sensor button. The button diameter is kept as the diameter of the human finger ie; 10mm. The sensor pad is isolated from the ground plane by a uniform gap. The size of the gap is important because if the gap is too small, too much field energy will go directly to ground. But if it is set too large then, it becomes difficult to direct the energy through the overlay. The gap of 5mm works well for 10mm diameter button.

Whenever a finger is present on a capacitor the capacitance is increased. This concept can be put into a number of applications. The figure below shows a charge transfer touch sensor QT113 which requires a common capacitor to function. 

So you can interface the touch sensor with it and design your own system.

Extreme Myths About Microprocessor.

In every single day we come across many intelligent devices that has a microprocessor embedded in it. People get passionate over processors more than RAM or Decoders. Every one has their own favorite processor which they like to recommend others and also to use over and over again. Legend and lore surrounds Microprocessor. Some are true but many are just myths which is believed to be true.

• Few Processor Choices.

This is the most subtle misconception while designing an embedded system that, we are having a choice of only 10-20 32-bit processors. But the fact is there are 100 different 32bit processors available for sale. This counting is not irrespective of different packages and speed; but dozen of companies make different CPU architecture and instruction sets.

• Intel Rules The World Of Microprocessors.
  

For lot of people microprocessor means Intel Pentium. The newspaper proclaims that Intel has a 95% share of microprocessor market. This are all media hypes. Intel Pentium has a dominant share of the PC business. But PC contributes to a very small slice of the Microprocessor pie. 
In 98% of the embedded CPU's Intel is not even in the top 5. ARM vendors alone sell about three times of the Intel sells Pentium.

• Instruction Sets Don't Matter.

Instruction set affect your assembly codes. We go on using instructions as it is meant. We have never thought of Instruction Sets in this context. Whether you use Java, C/C++ or Ada it is ultimately dumped into the hardware. Performance, predictability and power consumption are heavily dependent on the underlying instruction set.

Let us take an example of multiplying two numbers. This is a very easy job and hardly any programmer will worry. But different chips handle multiplication in different ways. Many RISC chip couldn't even do multiplication. So the early RISC compilers had to synthesize their own integer multiplication function. But  it wasn't fast operation. Now the processors have a built in multiply instruction, but not all multipliers are the same. Some chips can multiply two numbers much faster, than the others and it has nothing to do with clock frequency. 
Figure illustrates this phenomenon:-


Hitachi's SH7604 and SH7708 can multiply 32 numbers in four cycles whereas Motorola's 68020 and 68030 take more than forty cycles to do the same.

• RISC Is Better Than CISC. 

Both RISC and CISC have their strength and neither is better all the time. RISC chip provides more code density, smaller memory footprints and more mature software tools. But RISC chips have higher clock rates. So the selection clearly depends on your application.

• JAVA Chips Are Coming.

Java language was never meant to be handled in hardware. Garbage collection, threads, stack orientation, and object management take a megabyte worth of Java virtual machine to translate into something that even the fastest computer of today struggles to execute. Decades of computer evolution and research in companies and universities around the world has failed to produce any thing like Java machine. But java accelerator chips are available. It executes 30% to 60% of Java Bytes into hardware.

• Dhrystone-MIPS Are A Useful Benchmark.

To understand what DMIPS are; you will first have to understand what exactly a Dhrystone is.  Dhrystone is a synthetic computing benchmark program which represents the general processor performance. The Dhrystone counts only the program iteration completion per second. When Dhrystone is divided by 1,757 then it is represented as DMIPS.(Dhrystone million instruction per second.)

As the instructions are not same from processor to processor so counting and comparing them is meaningless. For Example a same high level task may require more instructions on a RISC machine but may get execute as a single CISC instruction.  

• Arm Consumes Lowest Power.

In the early ninety's the arm was one of the first 32 bit processor to be embedded into the ASIC's rather than soldered alongside as a separate chip. It was possible because ARM had no cache, no drivers, no outside bus and not much of an instruction set.
But today, there are plenty of 32 bit processors available as ASIC's core. They use even less power both in standby or when they are active.  

• Higher The Performance Higher The Price.

Cost it what  it is required to built a chip but price is what marketing department wants it to be. Price is determined by market forces and there is no such relation between price and Performance.
