Electronic Circuits and Diagram-Electronics Projects and Design

From our childhood days, we have studied that nothing in this planet travels faster than light. It has been defined as the ultimate speed in our universe. This has been backed up by many experiments, tests and measurements in many ways possible.   But all these remain as just theories, as a simple neutrino transfer experiment conducted by physicists at The European Organization for Nuclear Research (CERN) from their headquarters in Geneva to Gran Sasso Laboratory in Italy (732 kilometres away), proved to be faster than light speed. The neutrinos had some special characteristics and did not interact with normal…

Doctors have been successful in replacing dead intestines and tracheas, designed by tissue engineers. But, the same process on larger organs has been a little slow as they could not design blood vessels like capillaries that deliver the wanted nutrients to the other tissues. If the nutrient supply is stopped or cut-off at intervals, the tissues will not live for a long time. A engineering research team from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Germany have finally found a solution by printing the capillaries with the help of a 3-D printer. The basic element behind the…

This article is not something related to our usual electronics technology, rather we are dealing a little with web technologies and Internet marketing stuff. I know many of you electronics geeks and enthusiasts may not be well aware of technologies behind websites and techniques used to bring loads of traffic to a website. I will speak a little about these interesting stuffs in this article. Image Courtesy You all know CircuitsToday is a very popular electronics website providing basic contents for students and hobbyists. In addition we write a little about technology news too, which are related to core electronics….

Researchers from the University of Utah were successful in making a wi-fi device that could detect and analyze breathing patterns. This device will not only pave way for cheap and easy breath monitoring systems, but will also help doctors to get a faster and more efficient analysis of patients suffering from breathing problems like sleep apnea, asthma, sudden infant death syndrome and so on. Neal Patwari experimenting with tranceiver The first experiment was conducted on team leader Neal Patwari. He first timed his breathing to fifteen breaths per minute and tested his timing with the help of a carbon dioxide…

  A team of UC San Diego security researchers presented a paper on how your Automatic Teller Machine (ATM) pin code can be stolen using the heat that our fingers leave behind. With the help of a digital infrared camera, the person immediately following you can know the keys you pushed, with 80% accuracy. Frightened? Don’t worry! There are some drawbacks to this method of stealing ATM pins. Even if the criminal can determine the digits pressed, it is very difficult for him to know the order in which they were pressed. That means he will have to use different…

Hypersonic Sound System Technology Image Credit Hypersonic Sound (HSS) is one of the most revolutionary digital sound reproduction technologies of this century. It is considered as one of the most innovative approach to sound engineering. This technology was developed by American Technology Corporation. The biggest advantage of this technology is that it does not include any complex electronic circuits having enclosures, crossovers, woofers, and midrange or tweeter elements as compared to conventional loudspeaker system. This technology also provides ideal characteristics to almost all audio frequencies (normal loudspeakers is not ideal for all frequencies such as 20Hz to 20 KHz). HSS…

Polymer Solar Cell Scientists from the Universities of Sheffield and Cambridge have started a new research that promises to produce cost-effective and highly efficient cling film solar cells. The idea was first published in the journal “Advanced Energy Materials”. According to them, these solar cells can also be produced with much ease. This has clearly become a great advancement in the field of renewable solar energy. To carry out the tests, the ISI Neutron Source and Diamond Light Source at STFC Rutherford Appleton Laboratory in Oxfordshire were used. Until now, two types of solar cell materials are being used –…

Since, 1932, researchers have been successful in combining hot fusion with nuclei. Till then the concept of cold fusion was used and did not produce any satisfactory results. The research in hot fusion is still continuing and they have been successful in providing danger-free, very good potential energy source without producing much wastes. Some of the main advantages of a fusion power plant is that they will not produce any high radioactive waste which will live for a long period. They cannot be used as a deadly weapon and cannot be subjected to meltdown. Thus, it is clear that hot…

We have already discussed different concepts of high-efficiency computers like Brain-like Computers, which is soon to become a reality. Two researchers at the University of California, Berkeley, Jeffrey Bokor and Brian Lambson are developing a new concept called “Magnetic Microprocessors”. According to them, this new concept would be so efficient that the energy consumed by them will be very less as described by the 2nd law of thermodynamics. Though the multi-processors used today are known to be efficient, the fact is that the energy consumed by them is fairly high when compared to its speed and multi-tasking capability. As the name…

  We have already discussed about StunRay Technology and its capability to substitute tasers and guns used in law enforcement. But, there are some limitations to the amount of damage you can do to the suspect if he is not in front of you. That is why tasers are considered more effective as it will leave the suspect electrocuted and numb for a quite a long time, which is more than enough to seize and cuff him up. But, the tasers used now have a problem of “capability gap”. That is, if the suspect is standing at a distance of…
