Mims also wrote for other magazines; "Experiment With a $32 Solid State Laser" was featured on the June 1972, cover of Radio-Electronics. In October 1975, Mims convinced Art Salsberg, Editor of Popular Electronics, to offer him a monthly column, the "Experimenter's Corner". He later added two additional columns, "Project of the Month" and "Solid-State Developments". Mims wrote for this magazine until it ceased publication in April 1985. Meanwhile, Salsberg had started another hobbyist magazine, Modern Electronics; and Mims wrote a monthly column and was a contributing editor. In the 1970s, electronic components such as resistors, capacitors, transistors and even integrated circuits were common enough that interesting projects could be constructed at home with simple tools. The Radio Shack stores sold books that featured projects that could be constructed using the components that were being sold in their stores. In 1972, Mims wrote two hobbyist project books for Radio Shack. His books could be understood by hobbyists and were illustrated with hand-drawn schematic diagrams and, eventually, hand-lettered text. This style proved popular, and Radio Shack commissioned 36 books between 1972 and 2003. His “Understanding Digital Computers” sold more than 100,000 copies. The hand-lettered books sold more than 7 million copies, the best seller of which was “Getting Started in Electronics”, which sold 1.3 million copies and is still in print. By the 1990s, components became smaller and it was difficult to assemble electronics projects with low-cost hand-tools. The interest in electronic kits and experiments declined, and in 2003 Radio Shack scaled back their project books and components. (Four volumes of Mims’ 16 Engineers Mini-Notebooks are still available. Mims developed and wrote the manuals for three Radio Shack lab kits: Electronics Learning Lab, Electronic Sensors Lab and Sun & Sky Monitoring Station. Mims also wrote articles for a wide variety of general-interest and technical magazines and 849 weekly science columns from 1999 to 2016 for the Seguin Gazette, many of which were also published by the San Antonio Express-News under “The Country Scientist” heading In the 1990s, he began conducting serious science and began to write about atmospheric science and his measurements of solar ultraviolet radiation and the Earth's ozone layer with homemade instruments that sprang from one of his columns for “The Amateur Scientist” in Scientific American (“How to Monitor Ultraviolet Radiation from the Sun, August 1990). His finding of a drift in ozone retrievals by NASA’s Nimbus-7 satellite led to
