Tired of competing with his own artwork, Glasgow native and stage actor Clive Mitchell threw out the microcontrollers and discrete oscillators he once used to produce highly animated art pieces. Designed to be displayed in a frame, his latest creation consists of a passive grid of low-intensity diffused LEDs that creates a form that's pleasing to look at without getting in your face. He wires the LEDs in series of circuits of four with a 330 ohms resistor for each circuit, powered by a cheap, unregulated power supply and suitable for framing.

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
