Cara Lamp is Crystal-Like LED and Silver Circuit-Board Beauty

Those little interlaced blades of ice you sometimes get on the edge of ultra-cold things in wet air: that's the image that popped into my head on seeing the Cara lamp. It's by designer Andreas Ostwald and that fragile crystal-like shape is composed of interlocked flat white circuit boards with silver tracks, sprinkled… » 10/30/08 7:18am 10/30/08 7:18am

Scientists Build Computer Circuit From Brain Cells

Scientists at the Weizmann Institute of Science in Rehovot, Israel have managed to build reliable logic gates out of neurons instead of wires. The process actually sounds fairly simple: a glass plate is coated with cell repellent then etched with the desired circuit pattern. The pattern itself is coated with a… » 10/23/08 11:00am 10/23/08 11:00am

New Memory Resistor Circuit Could Make Instant-Boot PCs, Emulate Brain…

A fourth circuit element called memristor (the first three being resistors, capacitors and inductors) has been proposed since 1971, but HP labs has finally made a working physical model of the thing. What's so special about this type of circuit? It remembers how much charge previously flowed through it, leading to… » 4/30/08 3:16pm 4/30/08 3:16pm

Geek-Out the Kiddos Early with Snap Circuits

Want to ensure your children will never become a booze-chugging floozy-banging meathead jock? Start them out early on the path to geekdom with the Snap Circuits. Snap Circuits teaches kids all of the ins and outs of circuits without the need of a soldering iron. Some of the basic projects include radios, digital voice… » 11/06/06 10:30am 11/06/06 10:30am
