This whopping 16-bit computer processor is being built by hand, transistor by transistor

Pics A bloke in Cambridge, UK, is building a computer processor using 14,000 individual transistors and 3,500 LEDs – all by hand, piece by piece. James Newman said his Mega Processor relies almost entirely on the hand-soldered components, and will ultimately demonstrate how data travels through and is processed in a simple CPU core …

BBC gives naked computers to kids (hmm, code for something?)

Comment The Beeb is trying to recapture the past glories of the BBC Micro with the “Micro Bit”, a single board computer it’s giving to every single 12-year-old in the UK, with the hope of inspiring them to learn programming or (perhaps more politically correct) coding. This still-in-development device, part of the wider Make it …

Samsung turns off lights on LEDs worldwide – except in South Korea

Samsung has decided to stop pushing its light emitting diode business outside of South Korea, despite reckoning it would be a growth area a few years ago. Like Philips, Sammy has realised that LED is not, after all, where it’s at, and it will be shutting the unit down overseas. Philips recently announced it would be spinning …

White LED lies: It's great, but Nobel physics prize-winning great?

Worstall @ the Weekend This year's Nobel Prize in Physics went to the three Japanese guys who worked on, and got right, the blue LED. It's an excellent piece of work, enabling a whole new ensemble of energy efficient lamps and colour LED screens, and fully deserving of the prize. And yes, it might well change society in wondrous and wonderful ways. …

Ford Mondeo has an LED headlight

Bright lights, affordable motor: Ford puts LED headlights onto Mondeo

Vulture at the Wheel Ford has announced its first car with dynamic LED headlights, which apparently provide as much light as Xenon bulbs – and last for the lifetime of the vehicle. Because LEDs are very much smaller than traditional bulbs, they can affect the whole design of the front end of a car. Ford is trumpeting the freedom it gives them in …

Optical computing a step closer with SINGLE-MOLECULE LED

Researchers at IPCMS in Strasbourg, working with a team from the Institut Parisien de Chimie Moléculaire (CNRS/UPMC), have produced an LED that consists of a single molecule. While it's unlikely ever to serve as a display, the molecular LED is an important step forward in miniaturising components to provide optical …

Forget Wi-Fi, boffins get 150Mbps Li-Fi connection from a lightbulb

Scientists in China are reporting great success in replacing traditional Wi-Fi radio traffic with Li-Fi, a system that uses the light signals from an LED lightbulb to provide a line-of-sight data stream. Li-Fi, or light fidelity, was developed by Professor Harald Haas at the University of Edinburgh, who was disenchanted with …

Ciseco Pi-Lite: Make a Raspberry Pi trip light fantastic with 126 LEDs

Review Not so long ago, a hardware hacker called Jimmie Rodgers decided to solder 126 LEDs onto a small circuit board that could be plugged into the Arduino microcontroller kit. He dubbed it the LoL Shield: LoL for "lots of LEDs", and shield because that’s that’s what Arduino add-ons are called. Ciseco Pi-Lite LoL Shield for RPi: …

Fireflies donate gut feelings to LED research

Structures that help fireflies produce bright light from their abdominal lanterns have been mimicked in the lab to increase the efficiency of LEDs. In their Optical Express article, the researchers explain that the jagged structures they found on the Photuris Lampyridae firefly enhanced the glow of their lanterns. By creating …

The amazing magical LED: Has it really been fifty years already?

Next time I hear Coldplay festively crooning "May all your troubles soon be gone, Oh Christmas Lights keep shinin' on," I'd like to think that far from lamenting some lost love, they're paying solemn tribute to the humble but illuminating LED. The Light Emitting Diode celebrated its 50th anniversary this year. It's easy to …

World+Dog hails 50th birthday of the LED

The Light Emitting Diode (LED) is 50 years old. Well, kind of... It’s certainly 50 years since Nick Holonyak, working at GEC’s Syracuse, New York facility, developed what is considered the first LED capable of generating visible light. Holonyak’s LED was also the first to be in form ready for commercial usage. He wrote up his …
