When MC Hammer rapped ‘You can’t touch this’ little did he know of the work being carried out by a group of scientists at Bristol University. The team led by Dr Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah and Tom Carter have produced an ultrasonic sound system able to generate 3D shapes […]

This illustration represents the four-layer prototype high-rise chip built by Stanford engineers. The bottom and top layers are logic transistors. Sandwiched between them are two layers of memory. The vertical tubes are nanoscale electronic …more For decades, the mantra of electronics has been smaller, faster, cheaper. Today, Stanford engineers add a fourth word – taller.

I work as a software developer for a biology lab where my day job consists of creating applications to deal with big data visualisation. Recently however one of my colleagues had the need to take regular temperature measurements form a range of jars of liquids over quite an extended period. The commercial available solutions to

12kbps simple audio data transfer for AVR Posted in electronics, embedded I needed a way to transfer data to AVR This blog post is about my adventures in implementing a stupidly simple way of transferring data over audio to AVR (and why not other embedded chips too), reaching speeds up to 12kbps with really tiny

We have published a digital code lock using arduino some weeks before. This one is a little different. The earlier version was based on a defined password, where the user can not change it. Moreover there was no LCD display interfaced with the project to output lock status. This project is a much improved version
Digital Code Lock using Arduino with LCD Display Continue Reading
Arduino clones are ubiquitous. A quick web search or a look at any electronics hobbyist website will turn up some kind of Arduino-like microcontroller board. Studies have shown that the absolute last thing the world needs is another Arduino clone that adds nothing or very little to existing designs. One might surmise that these are

This tutorial is an introductory tutorial on getting started with the MSP430 series of controllers by Texas Instruments. There are millions and trillions of ways to start using microcontrollers. Hobbyist or people who find hard to code normally prefers Arduino as their coding environment, while engineers might prefer using AVR/PIC. The MSP430 microcontroller is an

Sip-and-Puff (SNP) controllers are nothing new – you’ve probably seen one in action yourself. SNPs are often seen on electric wheelchairs and allow individuals who can’t use their hands to control their wheelchairs (or whatever else) by either “sipping” (inhaling) or “puffing” (exhaling) into a straw. Depending on how hard the individual inhales or exhales,

Texas Instruments is now sampling to its third-party developer network the 0.47-in. TRP Full-HD 1080p chipset—the smallest TI chipset capable of generating brighter, more efficient full high-definition projection displays from small form-factor electronics. The chipset is based on DLP Cinema technology and employs the DLP4710 digital micromirror device to deliver sharp, clear images in a
Tiny 1080p chipset enables full HD projection Continue Reading
Description The MAX2173 is a highly integrated direct-conversion tuner for digital audio broadcast (DAB) and terrestrial digital multimedia broadcast (T-DMB) applications in the 168MHz to 240MHz (VHF band-III) and 1452MHz to 1492MHz (L-band) frequency bands. For FM and DRM+ reception, a low-IF conversion is used, covering a frequency range of 76MHz to 108MHz (FM band).
