3D Printers: Change the Shape of Your 3D-Printed Objects

When you print 3D objects on your 3D printers, they remain stable. Other than deteriorating over time, the objects do not change by themselves. However, that may be changing now. Scientists at MIT have created a new technique of printing 3-D objects where you can change the polymers in the object after printing. That means change the color of the object, grow or shrink it, or even change its shape entirely. Associate Professor of Chemistry at MIT, Jeremiah Johnson led the research, along with Read more [...]

IOT: The Internet of Things Helps Manage Decisions

In any era, one of the characteristics of a good leader has always been their ability to take a good decision with the limited information available to them. According to the 26th US President Theodore Roosevelt, the best thing to do in a moment of decision is doing the right thing, the next best thing is doing the wrong thing, while the worst that anyone can do is doing nothing. This brings us to the IOT Expectations are the Internet of Things (IoT) will be networking billions upon billions of Read more [...]

Bipedal Robots Walk Agilely on Two Legs

At the New Economic Summit (NEST) 2016 conference, in Tokyo, Japan, Andy Rubin unveiled an awesome new bipedal robot from SCHAFT. The new robot can easily climb stairs, carry a payload weighing 60 kilos, balance on a pipe, and move in tight spaces. In fact, they even showed a video where the robot can be seen climbing a narrow staircase. By positioning its legs behind its body, the robot is shown cleaning the stairs using a spinning brush and a vacuum type appendage attached to its feet. The video Read more [...]

Researchers Develop Thermoelectric Organic Transistors

Linkoping University scientists have made possible an organic transistor that is driven by temperature changes instead of by an electrical signal. Made of a thermoelectric material, the transistor brings about an appreciable current modulation for just a single degree rise or fall in temperature. Professor Xavier Crispin, based at the Laboratory of Organic Electronics of the university, states that heat driven transistor is the first logic circuit to be developed that makes use of thermoelectricity. Wide Read more [...]

Metamaterial Cools Buildings without Using Energy

Engineers at the University of Colorado Boulder have built a metamaterial that can be used to cool structures without drawing on any energy. The material can also cool objects placed in direct sunlight without using water. A metamaterial is an artificial substance with remarkable properties not possessed by natural substances. According to Xiabo Yin, an assistant professor at Colorado Boulder and a director of the research, the new metamaterial could be a game changer in the field of radiative Read more [...]

PiFM: A Pirate Radio with the Raspberry Pi

The popular single board computer, the Raspberry Pi (RBPi), can work as a radio transmitter as well. Using a simple hack, you can turn your RBPi into a powerful FM transmitter with adequate range to cover a bike parade, high school ball game, silent disco, DIY drive-in movie, or even your entire home. However, the broadcast frequency covered by the RBPi is rather large—one to 250 MHz, and there is a possibility this will interfere with government bands. Therefore, it is advisable to limit the transmissions Read more [...]

Colorful Images from Electron Microscopy

Almost everyone treats Christmas as the time to get away from regular work. Surprisingly, there are exceptions, such as Roger Tsien. This late biochemist would do an extra two weeks of uninterrupted research in his lab during Christmas. In one of his sojourns, he gifted the world the first electron micrographs—in color. His method used to create them will dramatically advance cell imaging. Scientists use Electron Microscopy (EM) for magnifying objects up to 10 million times their original size. Read more [...]

The Energy Efficient RRAMs

Engineers at Stanford are making 3-D memory chips that can offer faster and more energy efficient solutions for computer memory. These are the Resistive random Access Memory or RRAMs, which are based on a new semiconductor material. It stores data based on temperature and voltage. However, the actual workings of RRAMs continued to be a mystery until a team at Stanford used a new tool for their investigations. They found the optimal temperature range to be lower than they had expected. This could Read more [...]

Why not wear Digital Clothes?

We carry so much digital technology on our person all the time; it is quite natural to wonder about digital clothes. Technologists and manufacturers assure us that the field of printed electronics to produce digital clothes will be making significant advances in 2017. We have some indications as to what is to be expected. For instance, there is the safety garment that Flex and MAS Holdings is planning on producing. The garment has LEDs embedded into the fabric. As of now, the manufacturers are Read more [...]

The Next Generation Wireless Audio

We have been seeing wirelessly connected speakers for quite some time now, mainly using the Bluetooth technology. Although convenient, Bluetooth technology has its limitations because of bandwidth and range. The first to overcome this was Sonos who introduced Wi-Fi based wireless speaker system with their SonosNet mesh-networking technology. Several others followed, such as DTS’s Play-Fi, DLNA or Digital Living Network Alliance, and Apple AirPlay among the leading few. The most recent is the Google Read more [...]
