Single Electron Reader : Next setep to Quantum Computing

Recently Australian scientists have made a major breakthrough in the study of quantum mechanics.They were able to read the spin of a single electron on a silicon wafer. From the University of New South Wales:
A team led by UNSW engineers and physicists has achieved a breakthrough that brings a super-fast quantum computer a step closer to reality by developing a “single electron reader” – a key building block in creating a silicon-based quantum machine.
Quantum computers promise exponential increases in processing speed over today’s computers through their use of the “spin”, or magnetic orientation, of individual electrons to represent data in their calculations.
In order to employ electron spin, the quantum computer needs both a way of changing the spin state (the “write” function) and of measuring that change (the “read” function) to form a qubit – the equivalent of the bits in a conventional computer.
Well we are closer to a full electronics logic and data manipulation using Quantum Phenomenon.

Spectrometer : In a Pocket

An interesting project that brings smart phones and chemistry together.
    University of Illinois chemistry professor Alexander Scheeline has developed software that turns a camera phone, an LED, and a few other cheap tools into a spectrometer. Armed with these, he thinks we can bring high-end analytic tools to high school chemistry labs all over the world.

    “The potential is here to make analytical chemistry a subject for the masses rather than something that is only done by specialists,” Scheeline said. “There’s no doubt that getting the cost of equipment down to the point where more people can afford them in the education system is a boon for everybody.”

OpenSource Hardware: The next revolution

Recently Open-source Hardware summit was held in NY when all the Open Source geeks and gurus met to discuss on the next big thing: Open Source Hardware. For ages, electronics had been formidably closed and only a handful of corporates and big players had access. With the growth of open source software, people had freedom from the propitiatory software. The similar revolution was started with the AVR microcontrollers from Atmel as they gave the complete tool chain for free(story of AVR). Now this idea has come to a much mature phase where a global standard for hardware would be adopted:
The standard definition says:
Open Source Hardware (OSHW) Statement of Principles (Draft)
Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make and sell the design or hardware based on that design. The hardware’s source, the design from which it is made, is available in the preferred format for making modifications to it. Ideally, open source hardware uses readily-available components and materials, standard processes, open infrastructure, unrestricted content, and open-source design tools to maximize the ability of individuals to make and use hardware. Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.
This spec has already approached a 1.1 of release. Here is the 0.4 draft that it began with.
We wish all the OHS supporters best of luck and would try our level best to contribut this movement.

Sintel: Open Source Wonder Movie

Got to watch this:


“Sintel” is an independently produced short film, initiated by the Blender Foundation as a means to further improve and validate the free/open source 3D creation suite Blender. With initial funding provided by 1000s of donations via the internet community, it has again proven to be a viable development model for both open 3D technology as for independent animation film.
This 15 minute film has been realized in the studio of the Amsterdam Blender Institute, by an international team of artists and developers. In addition to that, several crucial technical and creative targets have been realized online, by developers and artists and teams all over the world.
This is a real nice creation and demostrates the Power of Opensource.
