Generally, the smaller the wires in a semiconductor get, the more resistance they have making them less efficient. The team of researchers from the University of New South Wales has discovered a way to make tiny wires that have extremely low resistance. The tiny wires are made by stringing together individual atoms on silicon making wires as tiny as four atoms wide. For those of you counting, four atoms measure about 1.5 nanometers.

The team prepared each wire by lithographically writing lines onto a silicon sample with microscopy techniques and then depositing phosphorus along the line. The closely packed phosphorus atoms were then encase in silicon and resistivity stayed down, at least at low temperatures. The new wires have the carrying capacity of copper and could allow microchips to continue the shrink and meet Moore’s law ever-increasing demands.

Matt over at Liquidware decided to build an “open source Gameboy” (known as the Gamepack) using off-the-shelf parts, including the modder-friendly Arduino microprocessor. While the Arduino may provide the brains of the operation, the 128×128 TouchShield Stealth color OLED touchscreen is most definitely the soul. Rounding out the build is an Inputshield board, which provides a tiny joystick (complete with rumble) and control buttons as well as a flat Lithium battery pack.

The Gamepack system is now available in kit form so you can build one for yourself. At this point, the Gamepack only runs some rudimentary homebrew demo code, but the hope is that others who grab the kit will contribute more advanced games, or maybe even a Nintendo emulator.

At $249 for the Gamepack kit, you could buy more than 10 used Gameboys. But none of them would be nearly as cool as the one you built yourself.
