Have you ever looked at the time, and then had to look again because it just didn’t register? This phenomenon seems more prevalent with phone timepieces, but it’s been known to happen with standard wall clocks, too. This latest offering in a stream of unusual clocks fashioned by [mircemk] solves that problem by forcing the viewer

Hey! This I’ble is now out of date! I made an updated version which you can read here! Hope you find it fun and useful! ~~~~~ Thus far, I’ve shown you how to create wheels out of household items, severalmotorizedchassis out of cardboard, and a couple of simple and effective light sensors. Now, one of

Amorphous silicon-based Thin-film transistors (TFTs) are the foundation of many modern-day technologies, such as smartphones and flat-panel TVs. Still, it comes with a few drawbacks like performance limitations due to limited carrier mobility. Provoking the researchers in search of something better. As a result, Organic thin-film transistors (OTFTs) were developed. OTFTs have solved the problem with carrier mobility to
When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpressand Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because most of us are

Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum

Typically, amateur radio operators use the minimum power needed to accomplish a contact. That’s just part of being a good spectrum citizen, and well-earned bragging rights go to those who make transcontinental contacts on the power coming from a coin cell. But sometimes quantity has a quality all its own, and getting more power into

In July 2015, Intel and Micron Technology announced a new technology for memory and storage solutions called “3D XPoint™ technology“. It is a new category of nonvolatile memory that addresses the need for high-performance, high-endurance, and high-capacity memory and storage. Now Intel had produced its Optane™ technology that provides an unparalleled combination of high throughput, low latency, high quality of service, and high endurance. The new technology

A research group at the University of Hamburg has created a unique coulomb transistor that operates on the principle of the voltage control of the electron band gap in metallic quantum-dot nanoparticles. This Single-electron transistor represents an approach to develop less power-consuming microelectronic devices. It will be possible if industry-compatible fabrication and room temperature operation are achieved.
Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with much promise and, importantly, can also be produced very cheaply. Possible applications for this procedure are food packaging with
