Each week, the editor of Planet Analog finds items of interest and features and puts them into two sections, entitled “Also of Interest” and “Elementals”. Each cites items from publications outside the Planet Analog and EETimes portfolios.
It's an extension of our belief that engineers are interested in on-going tutorial on obviously relevant topics, as well as the serendipity of exploring topics which are not directly related to their jobs, but which will broaden their knowledge and sometimes spurs innovative and creative approaches. The first box highlights a few items of general interest to the engineer, while the second highlights some basic and tutorial electronic-engineering material.
Among the publications we check are IEEE Spectrum , Machine Design , Design News , Laser Focus World , EDN , Electronic Design , NASA Tech Briefs , and Physics Today , among others. Consider these items as “online-only” extras, and worth a look! (Please note: there are also links to the previous weeks' editions, at the bottom).
