Pentax has released a series of multi-colored variants of its K-r DSLR for the Japanese market. A collaboration with music store Tower Records results in a rainbow-themed version, including colorful Pentax logo and candy-colored handgrip. Meanwhile the company has also introduced a series of camouflaged grips for Japanese customers. These range from the traditional militaristic khaki through to a red and white mélange that will presumably blend in perfectly with the strawberries and cream at Wimbledon. The grips can be ordered with new camera or retro-fitted to existing purchases.
Camouflage options for the Japanese market include traditional khaki and can be

geotagging of images. The O-GPS1 unit attaches to the camera's hotshoe, allowing the camera to add latitude, longitude, altitude, UTC capture time and direction as image metadata. This data can be used to place images in mapping software such as Google Earth or as a means of file organization and retrieval. K-5 and K-r users also gain access to the 'Astrotracer' feature that predicts the movement of celestial objects and uses the sensor shift mechanism to track this movement to give astrophotographs with single points, rather than star-trails. The O-GPS1 unit will be available from mid June at a recommended price of $249.95/£229.99.
Press Release:

A handy GPS unit for digital SLR cameras offering innovative features for effortless geotagging of photos

PENTAX is today pleased to announce the launch of the PENTAX O-GPS1. Designed for use with PENTAX digital SLR cameras, this versatile GPS unit not only provides basic location data, but also offers an array of original features that allow users to effortless track and record details of their favourite photographic locations.
By simply mounting the O-GPS1 onto the hotshoe of a PENTAX digital SLR camera,* users can record the latitude, longitude, altitude, universal time coordinated (UTC) and aspect of the location they are shooting directly onto each image they capture. Image files carrying GPS location data, can then be used to track shooting locations and review location data on a PC. GPS location data stored on such files also makes it much easier to sort and file recorded images.
By coupling GPS data with the camera’s SR (Shake Reduction) system, the unit offers a range of unique, advanced applications, including ASTROTRACER, Simple Navigation and an Electronic Compass.
Major Features

1. GPS function for effortless recording of shooting location data

The O-GPS1 can be mounted on the hotshoe of a compatible camera and will record the latitude, longitude, altitude, universal time coordinated (UTC) and direction of the shooting location onto captured images. Using mapping software such as Google Earth™, the user can then easily recall shooting locations and directions on a map. This function can also make sorting and filing recorded images easier.Note: When the O-GPS1 is used in locations where it cannot receive signals from GPS satellites, location data may be in error or missing.
2. ASTROTRACER for effortless astronomical photographyWhen mounted on the PENTAX K-5 or K-r camera body, the O-GPS1 also offers the advancedASTROTRACER function,** which couples the unit with the camera’s SR (Shake Reduction) system and enables users to photograph celestial bodies. The unit can calculate the movement of stars, planets, and other bodies using the latitude obtained from GPS data and the camera’s alignment data (horizontal and vertical inclinations and aspect) obtained from its magnetic and acceleration sensors, then shifts the camera’s image sensor in synchronization with the movement of the objects.*** As a result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. This is the ideal tool for those interested in astronomy and it makes taking images much simpler, as it eliminates the need for additional accessories such as equatorial telescopes.
3. Simple Navigation to allow photographers to easily find favourite photo locationsThe O-GPS1 offers a Simple Navigation function, which calculates the direction and distance to a given destination from the users current position. The user can either locate destinations using location data stored on recorded images, or register and/or assign them by uploading location data created on a PC.****
4. Electronic Compass function to indicate and record directionThe O-GPS1 comes equipped with an Electronic Compass function, which displays the direction in which the user’s camera is pointing on its LCD monitor with great precision. This function works by using geomagnetism detected by the unit’s magnetic sensor and combining this with its GPS location data. The unit will then indicate the aspect of the camera in relation to true north. The user can also record directional data on captured images.
5. Other features1)  Simplified weather-resistant construction for use in light rain
2)  Independent power source (one AAA-size battery) to eliminate the need to draw power from the camera body
The PENTAX O-GPS1 will be available mid-June 2011, at the Recommended Retail Price of£229.99. 
* Compatible models are the K-5, K-r and 645D (as of May 2011). Some of the O-GPS1’s functions may not be available when used with the 645D.
Note: The camera’s firmware must be updated to the latest version In order to use the O-GPS1 properly with a compatible PENTAX digital SLR camera body.
** This function is available only when the O-GPS1 is mounted on a PENTAX digital SLR camera body equipped with a magnet-driven SR system.
*** The duration of ASTROTRACER operation may vary depending on photographic conditions.
**** At the time of purchase, the O-GPS1 has nine PENTAX international service centers as preset destinations.

OHMS LAW

Ohm's Law is extremely important in learning basic electronics.
What is Ohm's Law?  Ohm's Law is a formula that describes the relationship between resistance, current and voltage in an electrical circuit.  The formula is R (resistance in ohms) = (equals) V (voltage in volts) divided by I (current in amperes). 
That is:  R = V ÷ I
...and algebraic rules tells us that I - V ÷ R and V = I*R.
    I = V ÷ R, V = I*R, R = V ÷ I, and P (power in watts) = I*V are the fundamental formulas of Ohm's law.  (The * means to multiply the two quantities together).  Where V is the circuit voltage in volts, I is the circuits amperage in amps, and R is the resistance in ohms.    
Almost every electrical and electronic circuit involves resistance, current and voltage.  This is why it is vital you understand the relationships between them. 
As an experiment you can set up a circuit by connecting  resistors in series with a battery, measure the voltage across the resistors with a voltmeter, measure the current in the circuit by placing an ammeter in series with the resistors and the battery.  If you know the voltages and current in the circuit you can use Ohms law to calculate the resistance.  With the resistor out of the circuit you can measure it's resistance directly with an ohm meter.  The multi-meters today can measure ohms, volts and amperes (usually measured in milliamperes in practical circuits)  all in one piece of test equipment.
Below is a graphic chart showing the various relationships between resistance, current, voltage, and power and shows how one unknown can be calculated if you know the other two.

RESISTANCE

Resistance is the opposition to current flow in various degrees.  The practical unit of resistance is called the ohm.  A resistor on one ohm is physically very large but provides only a small resistance to current flow. A resistor of one million ohm's is physically small but presents a high resistance to current flow. A resistance that develops 0.24 calorie of heat when one ampere of current flows through it for one second has one ohm of resistance.  The unit of resistance is often represented by the Greek letter omega.  Resistors are often made of thin layers of carbon or lengths of small copper wire.  They can also be thin deposited layers of metallic material.  An image of a few resistor types is shown below.
What is electrical current? Electrical current, represented by the letter "I" in formulas, and it is the flow or rate of electric charge. This flowing electric charge is typically carried by moving electrons in a metallic conductor or electronic components such as resistors or transistors as an example. The unit of electrical current is the ampere, named after a french mathematician, Andre Marie Ampere. What is electrical voltage?  Electrical voltage is represented by the letter "V" in formulas and it is the electrical pressure a moving charge is under.  In the case of a static charge, one that is not moving, then voltage is the potential difference or pressure of the charge.  The relationship between current (I), resistance (R), and voltage (V) is represented by the formulas developed in Ohm's law.  We will study that in section 5 below.
RESISTORS AND RESISTOR CIRCUITS
Resistors can be connected in series (end to end), or in parallel (across one another), or in a combination of series and parallel.   If you connect two, 1/4 watt, 100 ohm resistors across one another (i.e. in parallel) then the total resistance in ohms is one half of one of the resistors.  In this example the resistance would be 50 ohms.  The wattage doubles as the current is now split between the two resistors.  The combination can now handle up to one half a watt safely.  If the two resistors were connected end-to-end (i.e. in series) the resistances add and in this case would be 200 ohms.  The wattage in this series case stays the same, 1/4 watt.  This information is handy to know as it is easy to calculate in your head and will allow you to devise additional resister values from a limited resistor bench stock.
RESISTORS IN SERIES: Connecting resistors in a string one pigtail to another is called connecting them in series.  When connected this way the resistance of one resistor adds to the next in line.  For example a 100 ohm resistor in series with a 500 ohm resistor is the same as having a 600 ohm resistor.  The wattage capability stays the same, in other words if the resistors are all 1/4 watt the string is 1/4 watt.  
Resistance in series resistance simply adds:   R = R1 + R2. This can be extended for more resistors: R = R1 + R2 + R3 + R4 + ...  
RESISTORS IN PARALLEL:  When resistors are connected in parallel (parallel; meaning they are tied across one another) their combined resistance is less than any of the individual resistances. There is a special equation for the combined resistance of two resistors R1 and R2:
Combined resistance of
two resistors in parallel:  
R =
 R1 × R2
 R1 + R2
For more than two resistors connected in parallel a more difficult equation must be used. This adds up the reciprocal ("one over") of each resistance to give the reciprocal of the combined resistance, R:
 1 
  =  
 1 
+
 1 
+
 1 
+ ...
R
R1
R2
R3
The simpler equation for two resistors in parallel is much easier to use!
Note that the combined resistance in parallel will always be less than any of the individual resistances.
Resistor values are measured in ohms.  A thousand ohms is written as 1k to eliminate all the zeros.  The k represents three zeros.  A million ohms is represented by 1M.  Therefore; 1000 ohms = 1k ohm and 1000k ohms = 1M ohm.  Since resistors are so small their value is marked by a color code.  
RESISTOR COLOR CODES Resistors use color coded stripes to indicate their value in ohms. 0=Black, 1=Brown, 2=Red, 3=Orange, 4=Yellow, 5=Green, 6=Blue, 7=Purple, 8=Gray, 9=White.    

A Critically evaluation the nature of design and technology

In early years curriculum the Foundation stage was introduced in September 2000. It was aimed for children aged 3-5 years of age to be covers the years they spend from the beginning of nursery or pre-school to the end of reception class in primary school. The aim of the foundation stage is to reach goals in children’s’ early years education to aid and enhance their development in preparation for future learning.

Each area of learning has a set of related early learning goals. Curriculum guidance for the foundation stage is intended to help teachers and other professionals plan to meet the diverse needs of all children so that most will achieve and some, where appropriate, will go beyond the early learning goals by the end of the foundation stage.

The Education Act 2002 extended the National Curriculum to include the foundation stage. The six areas of learning became statutory, and the Act also specified that there should be early learning goals for each of the areas.

The Act also established a single national assessment system for the foundation stage, replacing baseline assessment schemes. The Foundation Stage Profile was introduced into schools and other education settings in 2002-3. The Profile has 13 summary scales coveri

A brief history of robots

A robot can be defined as a programable, self controlled device consisting of electronic, electrical, or mechanical units. The notion of robots or robot-like automates can be traced back to medieval times. Although people of that era didn’t have a term to describe what we would eventually call a robot, they were nevertheless imagining mechanisms that could perform human like tasks.

As early as 270 BC an ancient engineer named Ctesibus made organs and water clocks with moveable figures. In medieval times, automatons, human-like figures run by hidden mechanisms, were used to impress peasant worshipers in church into believing in a higher power. The automatons, like the “Clock Jack”, created the illusion of self-motion (moving without assistance). The “Clock Jack” was a mechanical figure that could strike time on a bell with its axe. This technology was virtually unheard of in the 13th century.

By the 18th century, miniature automatons became more popular as toys for the very rich. They were made to look and move like humans or small animals. Automatons like “The Pretty Musician”, built around 1890, were able to turn their head from side to side while playing an instrument with their hands and keeping time with

Science, engineering and technology

The distinction between science, engineering and technology is not always clear. Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method.[13] Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.
Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result.
Technology is often a consequence of science and engineering — although technology as a human activity precedes the two fields. For example, science might study the flow of electrons in electrical conductors, by using already-existing tools and knowledge. This new-found knowledge may then be used by engineers to create new tools and machines, such as semiconductors, computers, and other forms of advanced technology. In this sense, scientists and engineers may both be considered technologists; the three fields are often considered as one for the purposes of research and reference.[14]
The exact relations between science and technology in particular have been debated by scientists, historians, and policymakers in the late 20th century, in part because the debate can inform the funding of basic and applied science. In the immediate wake of World War II, for example, in the United States it was widely considered that technology was simply "applied science" and that to fund basic science was to reap technological results in due time. An articulation of this philosophy could be found explicitly in Vannevar Bush's treatise on postwar science policy, Science—The Endless Frontier: "New products, new industries, and more jobs require continuous additions to knowledge of the laws of nature... This essential new knowledge can be obtained only through basic scientific research." In the late-1960s, however, this view came under direct attack, leading towards initiatives to fund science for specific tasks (initiatives resisted by the scientific community). The issue remains contentious—though most analysts resist the model that technology simply is a result of scientific research

About Modern Technology

Do you think modern technology has made life easier and safer? Or do you think that modern technology has made life more difficult and more dangerous? Technology today has made life easier and quicker but dangerous. As we look at technologies, questions are risen. By the way what are technologies? Modern technology is machinery that makes life easier. For example, microwave ovens cook food easily without using stoves and making a big mess. And dishwashers put all dirty dishes into the dishwasher and it washes them. Dishwashers are very easy to use and save time comparing it in the old fashion way. Today modern technology also has created problems because they are dangerous.
How is technology dangerous? The answer to this question is very simple. There's lots of incident where there is malfunction in technology. For example, if there is a problem with a car than the car won't be able to run, or if there is a technical mistake in a train computer system than the train would probably dysfunction and this could lead to a crash. Many people dislike the production of technology. Technology also creates financial problems in families because most technologies are very expensive to buy like the computers, televisions, refrigerators,
