Electronic Circuits and Diagram-Electronics Projects and Design

The U.S Army is famous for their military gadgets that are used to hunt down enemies and also navigate a battlefield at night. They began by using night goggles. But there were complaints about these goggles for being noticeable by the enemies. Another problem is that they had no way to track their exact location or the direction to head to. So, they started installing Global Positioning System (GPS) enabled devices so that the soldiers can find their way through the dark. But, this technology also has its drawbacks as the light from its display can easily help his enemy…

Germans, who are known for producing the most promising ad efficient mechanical and electrical designs, have lately created the strongest magnetic field in one of their labs. This new development is considered as a new world record and was created by the researchers at the High Magnetic Field Laboratory Dresden (HZDR). For developing such a structure, the researchers used a 2-layer, 440 pound copper coil, which is almost equal to the size of a water bucket. By their unique design, they were able to break the previous record of magnetic field produced (89 teslas) by creating 91.4 Teslas. The field…

We are used to making a closed conducting circuit diagram on PCB’s and Vera Boards. The same process can now be done by drawing on a paper with a silver coloured liquid metal ink.  This whole basic process has been named 3-D Handwriting by its inventors – researchers at the University of Illinois at Urbana-Champaign. The device consists of a normal looking pen in which an ink with conducting property is filled. This pen is then used to draw the closed electronic circuit on the paper. This circuit is then powered with the help of a battery. In the image…

Infrared View of NASA Lander We have seen hovering space crafts and missile enabled drones in movies like Star Trek, Avatar, G.I Joe and so on. From these pictures it is clear that such machines can easily stay in the air at a fixed position, just above a few feet from Earth, for any amount of time. In real life, such machine applications are used as an extra utility in space vehicles. NASA deployed such machines to carry astronauts and heavy machineries from the spacecraft to the landing station. Though we have seen how the machine is in movies, in…

One has seen the beauty of the sunrise and the sunset. Wouldn’t it be all marvellous to have a better view from high above the Earth? Out of the total population on Earth, only a few people have had the luck to get a view of Earth from space. A Canadian company called UrtheCast (the word “Urthe” is pronounced similar to “Earth”, though they could have really named it Earth!!) has made some contracts with a Russian space agency called Roscosmos to stream the video of Earth online. The live sight of a part of the Earth going into darkness,…

A new type of high-resolution nanoparticles detector called the “Whispering Gallery Resonator” has been developed by professors at the Washington University in St. Louis. The device mainly consists of a very small laser in the micro-size range along with a sensor that is used to detect the presence of individual viruses and particles in the nano scale and also count and measure them with single particle resolution. As its name implies, the properties of the device makes it more reliable to be used in huge cathedrals and galleries. As the inside of these buildings have acoustic spaces, a whisper from…

Don’t worry if you do not know how to play the guitar. From now on, the “PossessedHand” will play it for you. PossessedHand is a kind of a blood pressure cuff that is strapped onto your arm. This device will pass small electrical signals to your fingers in such a manner that it moves your hand accordingly at different angles. This device was developed by researchers at Tokyo University along with the technical cooperation of Sony Co. PossessedHand The device is mainly controlled by an Arduino Microcontroller along with other small tools like DIYers and so on. The electric signal…

We have already seen high-speed computers which can compute and process multiple instructions at the same time. But, there has never been a computer which can work as fast as and also resemble the biological systems of a brain. In a recently published article in the journal “Advanced Materials”, a study about the world’s first demonstration of a device, that is capable of multiple and simultaneous information processing and storage using phase changed materials was explained. The article was published by researchers at the University of Exeter. This new technology will clearly pave way for high-speed computers that are more…

People nowadays use credit and debit cards in order to purchase products. The use of coins for buying small things is fast diminishing and the use of currency notes has become more useful for people. As a part of giving these coins its old fame, the Dutch government have decided to make their coins a little more “high-tech”. They have decided to produce a limited edition of QR coded coins, consisting of silver 5€ coins and gold 10€ coins. The coins will be available for the public from June 22nd. The coins are now coded so as to take you…

According to the reports since 2000, the increase in the number of cars has also increased the amount of accidents all over the word. In USA alone, the number of accidents is more than 110 million and almost 1 million of them have been highly fatal. This clearly shows that car crashes is one of the most life taking hazards in the world. Researchers all over the world and car manufacturers have been able to provide luxury cars with all the major necessities like smooth, powerful rides, efficient vehicles, environment friendly vehicles and so on. There has also been a…
