The picturesque town of Ivrea, which straddles the blue-green Dora Baltea River in northern Italy, is famous for its underdog kings. In 1002, King Arduin became the ruler of the country, only to be dethroned by King Henry II, of Germany, two years later. Today, the Bar di Re Arduino, a pub on a cobblestoned street in town, honors his memory, and that's where an unlikely new king was born.

The bar is the watering hole of Massimo Banzi, the Italian cofounder of the electronics project that he named Arduino in honor of the place. Arduino is a low-cost microcontroller board that lets even a novice do really amazing things. You can connect an Arduino to all kinds of sensors, lights, motors, and other devices and use easy-to-learn software to program how your creation will behave. You can build an interactive display or a mobile robot and then share your design with the world by posting it on the Net.

The EV Transition Explained: Can the Grid Cope?

There have been vigorous debates pro and con in the US and elsewhere over whether the electric grids can support EVs at scale. The answer is a nuanced “perhaps.” It depends on several factors, including the speed of grid component modernization, the volume of EV sales, where they occur and when, what kinds of EV charging are being done and when, regulator and political decisions, and critically, economics.

The city of Palo Alto, California is a microcosm of many of the issues involved. Palo Alto boasts the highest adoption rate of EVs in the US: In 2020, one in six of the town’s 25,000 households owned an EV. Of the 52,000 registered vehicles in the city, 4,500 are EVs, and on workdays, commuters drive another 3,000 to 5,000 EVs enter the city. Residents can access about 1000 charging ports spread among over 277 public charging stations, with another 3,500 or so charging ports located at residences.

Janet Barth spent most of her career at the Goddard Space Flight Center, in Greenbelt, Md.—which put her in the middle of some of NASA’s most exciting projects of the past 40 years.

She joined the center as a co-op student and retired in 2014 as chief of its electrical engineering division. She had a hand in Hubble Space Telescope servicing missions, launching the Lunar Reconnaissance Orbiter and the Magnetospheric Multiscale mission, and developing the James Webb Space Telescope.
