Global Positioning System (GPS) is accessible to almost everyone by the introduction of smart phones. We can know our position and can locate any place by using satellites. Currently, the device has some limitations, as if GPS is not available inside houses, poor signal reception in remote places, and so on.  GPS systems currently can […]
World’s Smallest Stirling Engine In this era of nanotechnology, from a transistor to a heat engine, everything is getting small. While reducing to micro size, we may think that the efficiency and performance of the device maybe compromised. However, researchers are trying their best to maintain the same ratings of a conventional device with its
Researchers at the Massachusetts Institute of Technology (MIT) have always had the legacy of doing things that were so called “impossible†by the rest of the world. Recently they came with an idea of a new imaging system that can capture photons at a rate of one trillion frames per second. Yes, you heard it
When audio signals are transmitted over thousands of kilometres through radio transmission, the audio frequencies that lie within the frequency range of 15 Hertz to 20 KiloHertz has very small signal power and thus cannot be transmitted via the antenna for communication purposes. The radiation of electrical energy is only possible at frequencies above 20
CircuitsToday.com is introducing some simple LED circuits and projects which can be done even at home. These circuits and projects have already been tested and published along with circuit diagram, schematics, and a detailed working description for each one of them. Also go through the comment of each LED circuit article, so as to get
A PCB is used to connect electronic components electrically. This is done by making conductive path ways for circuit connections by etching tracks from copper sheet laminated onto a non-conductive substrate. A PCB consists of a conducting layer that is made up of thin copper foil. The insulating layer di-electric is laminated together with epoxy
X-ray Absorption Spectroscopy The information we know about the inside of the Earth (which includes the outer solid crust, the viscous upper and lower mantle, the liquid outer core, and the solid inner core), depends on the tests done by researchers through indirect methods. The way in which the different metals inside the Earth respond
Microlattice Material When it comes to light weight materials, the first thing that comes to our mind is Thermocol. Since its discovery in the year 1941, it has been used in many applications that are suitable for the common man like small life raft, disposable coffee cups, cushioning material in packaging, and so on. Since
In this article, we are listing all the best and useful op amp circuits we have published so far.The list features more than 25+ op amp circuits and projects which explore different applications of the operational amplifier IC. In addition to basic op amp circuits like the Differential amplifier, Inverting and Non-inverting amplifiers, Summing amplifier etc.,
We are listing a curated collection of 555 Timer Circuits and Projects published in our site before. We have a large collection of simple and advanced projects using 555 Timer IC. In this article, we have handpicked some really useful 555 timer circuits which will be interesting to electronics engineering students and hobbyists alike. While
CircuitsToday is listing some of the latest electronic seminar topics that have already been published before. A small brief idea about the seminar topic is also given below so that you can choose the right one to present. 1. Working of MAGLEV Trains This seminar topic gives a detailed explanation about one of the world’s fastest
Luc Douay, a researcher at the Pierre and Marie Curie University in Paris was successful in creating artificial red blood cells in a lab. The researchers were also able to inject it into a human and the results were positive without any side-effects. A healthy volunteer was first selected for the program, and his hematopoietic
For all electronic hobbyists out there, CircuitsToday is listing some of our own hobby electronic circuits for you. Most of these circuits have been tested by us. You can bring in your own modifications to the circuit. For beginners, these electronic hobby projects may be a little difficult. You can feel free to comment below
As CircuitsToday had discussed before, the General Aptitude Test in Engineering (GATE) exam will be held on the 29th of January 2012, and also on the 12th of February, 2012. The former will be an online exam and the latter is an offline exam. The details about the GATE examination structure and the various centres
Petman Boston Dynamics, an engineering company founded by Marc Raibert and his colleagues in the year 1992, have developed dynamic robots and its software for human simulation. Several innovations were made by them college life in Massachusetts Institute of Technology. They excelled in the field of robotics and developed robots that could run and
Flytrap Robot Researchers at the University of Maine and the Seoul National University have developed two robots that can not only hunt small bugs, but can also digest them for filling their stomach. Both the robots depict the same principle of Venus Flytraps, who snap-shuts its mouth as soon as an insect sits on its
Trevor Prideaux, a fifty year old man from United Kingdom was born without his left forearm. Years later he was given a prosthetic arm with limited degrees of freedom. Though he got used to the idea, he was still in need of more useful resources for his prosthetic limb. With the invent of smart
The National Ignition Facility (NIF) is a large internal confinement fusion (ICF) device setup at the Lawrence Livermore National Laboratory in Livermore, California. Till date, it is known to be the world’s largest and most energetic laser device. It has the size of three football fields with a height of a 10 stories building. The
Though the name sounds boring, the “Very Large Array”, abbreviated as VLA, is known to be one of the largest telescopes in the world. It is built and setup in a desert outside Magdalena, New Mexico, and covers hundreds of miles in diameter space. The whole device consists of 27 separate radio antennas. Each antenna
Photography has become more interesting and fascinating with the introduction of panoramic images. This technology not only brings in wide angle images, but also helps the viewer to get images that are more close to the human field. The images make us feel like we are seeing the image through our eyes, then and there.
Remember the James Bond flick “Die Another Day” where Pierce Brosnan camouflages his Aston Martin to escape from the villain, and also move undetected? Yes, the very same mechanism has now been developed by researchers at the University of Texas at Dallas. They were able to detect a unique characteristic in carbon nano-tubes with
People who go on adventure trips or hiking carry gadgets that send signals back to another station, who can easily track them if they go missing. Most gadgets available today are bulky and have to be kept safely inside the pocket. But they are prone to fall out and you may not even know it.
There will come a time when all medical conditions of a patient will be updated 24X7. But, for this to work, every person has to wear something that tracks all the body chemical imbalances, chronic diseases, diabetes, heart rates, glucose levels, and so on. Heather Clark, a professor of pharmaceutical sciences at the Northeastern University,
Piezoelectric devices are getting more and more popular due to their self-generating mechanism. As, a simple quartz crystal is able to produce an output voltage that is proportional to the stress applied to it, a lot of research is undergone in this field by instrumentation companies and also American defence agencies like DARPA. Recently, a
People often say that drinking and writing go hand in hand. This expression is turning out to be true since the invention of the typewriter that can mix different drinks with the help of a simple button press. The device was developed by a Russian artist and DIYer Morskoiboy. It mainly consists of a
