Colin Jeffrey

Colin discovered technology at an early age, pulling apart clocks, radios, and the family TV. Despite his father's remonstrations that he never put anything back together, Colin went on to become an electronics engineer. Later he decided to get a degree in anthropology, and used that to do all manner of interesting things masquerading as work. Even later he took up sculpting, moved to the coast, and never learned to surf.

Vortex bladeless turbines wobble to generate energy

By - May 19, 2015 4 Pictures
Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless wind-driven generator prototype produces electricity with very few moving parts, on a very small footprint, and in almost complete silence. Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantage of the power contained in swirling vortices of air. Read More

World's smallest beamsplitter paves way toward computing at the speed of light

By - May 18, 2015 2 Pictures

Silicon photonics is an emerging technology that incorporates electronic circuits using photons of laser light rather than electrons to transmit, receive, and manipulate information. As such, a silicon photonic CPU could potentially process information at the speed of light – millions of times faster than computers available today. In a step towards this goal, engineers working at the University of Utah have developed an ultra-compact photonic beam-splitter so small that millions of these devices could fit on a single silicon chip.

World’s first photosynthetic living matter-infused 3D-printed wearable

By - May 18, 2015 4 Pictures
Speaking at the 2015 TED conference in Vancouver, Canada, MIT professor Neri Oxman has displayed what is claimed to be the world’s first 3D-printed photosynthetic wearable prototype embedded with living matter. Dubbed "Mushtari," the wearable is constructed from 58 meters (190 ft) of 3D-printed tubes coiled into a mass that emulates the construction of the human gastrointestinal tract. Filled with living bacteria designed to fluoresce and produce sugars or bio-fuel when exposed to light, Mushtari is a vision of a possible future where symbiotic human/microorganism relationships may help us explore other worlds in space.

Review: Cubit programmable "make anything" electronic platform

By - May 13, 2015 16 Pictures

If you’re into electronics as a hobbyist, technician, or professional engineer, you know that you can spend many hours designing circuits, sourcing components, and breadboarding or soldering a project all together before you find out if your creation actually works. Wouldn’t it make life simpler if you could just start with a basic, multi-function controller and a few plug and play peripherals to get something – anything – up and running straight away and then which you could tweak and add to as you go? The makers of a new electronic design tool thought that this would be a good idea too and have created Cubit, a make anything platform that allows drag and drop software control over snap together hardware. Join Gizmag as we try a few builds to test out it out.

Electronic memory may bring bionic brain one step closer

By - May 12, 2015 1 Picture

Using a matrix of nano-sized memristors, researchers working at the Royal Melbourne Institute of Technology (RMIT) and the University of California, Santa Barbara claim to have constructed the world’s first electronic memory cell that effectively mimics the analog process of the human brain. By storing memories as multiple threads of varying information, rather than a collection of ones and zeroes, scientists believe that this device may prove to be the first step towards creating a completely artificial, bionic brain.

Smartphone microscope lens that costs just pennies to make

By - May 12, 2015 4 Pictures

Microscopes can be expensive pieces of gear, making access difficult – or non-existent – for students and medical staff in isolated and poorer locales. To help address this, researchers at the University of Houston (UH) have fashioned a lens designed to fit on almost any smartphone. It has the ability to magnify images up to 120 times their original size, and at an estimated production cost of just three cents per lens.

Optogenetic therapy shows promise for reversing acquired blindness

By - May 10, 2015 2 Pictures

Across the world many millions of people suffer from inherited conditions that progressively degenerate the light-sensing cells in their eyes, and eventually send them blind. Recently, however, researchers from the University of Bern and the University of Gottingen have developed a way to possibly reverse this damage by using a newly-developed, light-sensitive protein embedded into other cells in the retina to restore vision.

Earth-sized virtual telescope to study supermassive black hole at center of Milky Way

By - April 29, 2015 3 Pictures
In astronomy, much like many other other aspects of life, bigger is better. Taking this adage to heart, astronomers at the University of Arizona are helping to build a virtual radio telescope the size of the Earth itself. With a resolution factor more than a thousand times greater than that of the Hubble Space Telescope, the new Event Horizon Telescope (EHT) will be used to study in fine detail the supermassive black hole at the center of our Milky Way.

World's first light-activated, molecule-sized switch gets turned on

By - April 22, 2015 1 Picture
In the pursuit of ever-shrinking circuitry for nanotechnology electronics, increasingly smaller devices and components are being developed. Now researchers at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) claim to have micro-miniaturized the humble electrical switch all the way down to molecule size and proven its operation for the very first time. Unable to flick such a tiny switch mechanically, however, the researchers instead used light to turn it on. Read More
