Do you want a photo book incorportating the sound of the sea and  birdsong,a novel with spoken dialog? Most Children may say yes.But how to invent such a product out?Yeah,this is all made possible by loudspeaker paper and electronic concealed in the cover. Such a T-book can currently be heard at the Frankfurt Book Fair ( here the T stands for the German word Ton,means sound ).Most fairs even book fairs are already loud enough. However,the future noise level looks like to keep increasing if  ...
Today,I would like to introduce a kine do remote controller built using PT2262,IC PT2272-M4 from PRINCETON and MAX485 from MAXIM.This is a four channel two core twisted pair remote controller. The PT2262 is an enconder( transmitter) whic PT2272-M4 is a decoduer (receiver) and MAX485 works as bridge for twisted pair communication between PT2262 and PT2272-M4.4 Channel 2 core twisted pair remote controller built using PT2262.When any of SW1-SW4 (S1-S4) tact switches is pressed, power is applied to ...
When in 2006, researchers at Harvard University, US, said they have made the best nanowire transistors to date. The devices consisted of germanium/silicon core/shell nanowire field-effect transistors (FETs) using high-κ dielectrics and a metal top gate geometry."We showed that our current Ge/Si nanowire FETs perform three to four times better than silicon CMOS [devices]," Charles Lieber of Harvard told nanotechweb.org, "thus demonstrating for the first time that there is a clear a ...
As the technology landscape continues to evolve and becomes ever mor complexs,more and more traditional electronic components are having to evolve to support new capabilities expecially connectors. Even emerging technologies, whether that’s artificial intelligence, the use of big data analytics, or smart wearable devices and drones, are being appropriated by the world’s military in order to improve the effectiveness and capabilities of their armed forces.Connectors may not be considered the most ...
Today,let's talk something about MSP430 interrupts and times.About "Interrupt"Do you know what is an "interrupt"?Interrupt is a signal that informs our MCU that a certain event has happened,causing the interruption of the normal flow of the main program and the execution of an "interrupt routine",that handles the event and takes a specified action.Interrupts are essential to avoid wasting the processor's valuable time in polling loops, waiting for external e ...
BackgroundNowadays,more and more people need wifi and they can not leave it.More and more family has connected with wifi even in undeveloping country or area.Today,let's make a wifi based home automation project to realize that controlling home devices by using wifi as wireless communication. In this project,we will using esp8266 wifi module and Arduino Uno R3,We have also posted a similar project using pic microcontroller based home automation over wifi. you may also like to check it.  ...
Nowadays,almost all the focus in transportation is on self-driving ars with more and more similar initiatives with google car.Trucks, however, could also benefit from extra automation and connectivity to enable preventive maintenance, improve safety, efficiency and cost. Might we therefore one day soon see trucks on our roads with no driver in the front seat?Jörg Rüger's comment“Not for at least 10 years; I don’t think the public would accept it,” argued Jörg Rüger, president of commercial v ...
Do you know Dallas Semiconductor which is owned by Maxim Intergrated now? It's well known for making some excellent real-time clocks(RTCs). Let me take an example: DS1307 is simple,works with essentially any cheap 32,768Hz watch crystal,is easily accessible over I2C,and is extremely power efficient( 500nA current when running the oscillator on battery power).As great as it is, the DS1307 has a major drawback: it relies on an external crystal and lacks any sort of temperature compensation. Th ...
There is no doubt that the use of LCD headlamp is a succcessful further step towards digitalizing lighting. LCD headlamp which enables complex functions will also be relevant to autonomous driving.Let's talk something about the following research project about developing a headlamp basics on a LCD (  Full name is Liquid Crystal Display )which made by HELLA and seceral partners.This technology is an good example already known in the home entertainment field.About The ProjectIn the contex ...
Have you heard of Silicon carbide power devices yet? Researchers are rolling out a new manufacturing process and chip design for silicon carbide (SiC) power devices, which can be used to more efficiently regulate power in technologies that use electronics. The process -- called PRESiCE -- was developed to make it easier for companies to enter the SiC marketplace and develop new products.(Silicon carbide power devices, like the one shown here, are more efficient than their silicon counterpar ...
A team of University of Wisconsin-Madison engineers has created the most functional flexible transistor in the world -- and with it, a fast, simple and inexpensive fabrication process that's easily scalable to the commercial level.It's an advance that could open the door to an increasingly interconnected world, enabling manufacturers to add "smart," wireless capabilities to any number of large or small products or objects -- like wearable sensors and computers for people and an ...
Today I want to share an LED strobe design project I found in electronic-lab, which you can do it by yourself. Strobe provides regular flashes of light. Usually Strobes are designed using Xenon Tubes. Here is LED based simple solution that can be used as strobe for entertainment and events and also as warning signals. Project is based on PIC16F1825 micro-controller with two digit frequency display.Project provides TTL output signal, frequency 1Hz-25Hz, Tact switches provided to set the frequency ...
A Tomsk Polytechnic University study reveals how topological vortices found in low-dimensional materials can be both displaced and erased and restored again by the electrical field within nanoparticles. This may open exciting opportunities for memory devices or quantum computers in which information will be encrypted in the characteristics of topological vortices.(Vortices in nanoparticles exposed by the electrical field.

Everytime you want to create a PCB Design you need to draw holes, pads and wires for your circuit. Then you send this drawing to a manufacturer or you etch it yourself. What if you want to creat a circuit board by yourself but sounds hard? Don’t worry, there are many free tools out there that will help you do this.There are just a few steps you need to go through. And anyone can do it – even if you have no experience from before.To make a printed circuit board you need to:1. Design schematics2.  ...
