Scientists are trying to break the boundaries of Moore’s law by taking a phosphorus atom and create a working transistor as the gate to control electrical flow.
Moore’s law describes a long-term trend in the history of computer manufacturing whereby the number of transistors that can be placed in the same amount of space doubles approximately every two years.
Michelle Simmons, director of ARC Center for Quantum Computation and Communication Technology at the University of New South Wales, Australia, took an atom and etched it into a silicon bed with “gates” to control electrical flow and metallic contacts to apply voltage to start/stop current.Â It’s the first such device to be precisely positioned using
The tech world is changing for the better.Â We are seeing longer lasting batteries, devices which require less juice and smarter power management.Â Good example is the PowerUSB Bar.
This power bar will automatically shut down the devices it’s powering based on time of day or clock settings.Â For example, why power that laser printer when everyone is away from work?Â Better to power off the printer between 6pm and 7am, right?Â The PowerUSB Bar can do just that.
The PowerUSB Basic empowers you to put your old devices on a diet by programming when to shut off power to them. It looks like a standard 4 port power strip but 3 of the for outlets are programmable. The last outlet is always on so it’s reserved for the PC. And there’s also a 6 ft USB cord coming out of the power strip. Attach printers, chargers, speakers or external drives and let the PowerUSB Bar govern their power consumption.
Instructables has a nice USB LED lantern DIY project.Â I think the most important part about this project is getting a cool enough looking lantern.Â Make sure it’s 50s-60s style with some wear on ti.
