This is part of IEEE Spectrum's special report: Nuclear Power Gets a Second Look

Soon, most nuclear power plants in the United States, having gone on-line in the 1960s and 1970s, will be reaching the end of their 40-year operating licenses. If they are to continue operating, their licenses must be renewed, a process started 10 years ago by the U.S. Nuclear Regulatory Commission, in Rockville, Md.

Hi-fi, Radio, and Retro: The DIY Projects Spectrum Readers Love

They also really like Lego and hacking pretty much everything

An assortment of boxy devices, spread out as if on a display table.

Here are some of your favorite Hands On projects: An inexpensive but high-quality DIY audio amplifier (A) and its Web-enabled successor (B); an Arduino-powered replica of the groundbreaking Altair 8800 (C); a Raspberry Pi–powered color mechanical television (D); and (E), a home computer built with just five digital chips that uses an old hack to create an analog video signal.

This month we’re celebrating the launch of our second PDF collection of Hands On articles, which IEEE members can download from IEEE Spectrum’s website and share with friends. So we thought we’d take a look at the relative popularity of Hands On articles published over the last five years and share the top 15 projects our website visitors found most interesting.

Just to give a little peek behind our analytics curtain, the measure of popularity Spectrum’s editors use is “total engaged minutes,” or TEM, which combines page views of articles with how long visitors spend reading them. We use TEM because we’re not terribly interested in grabbing folks with a clickbait headline, only for them to bounce out before they’ve finished reading the first paragraph.
