Each week, the editor of Planet Analog finds items of interest and then features them in two sections, entitled “Also of Interest” and “Elementals”. Each cites items from publications outside the Planet Analog and EETimes portfolios. And we also have an archive of recent weekly Planet Analog Newsletters, as pdf files; see the list at the very bottom.
“Also of Interest” and “Elementals” is 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 items of general interest to the engineer, while the second highlights 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 , Microwave Journal , RF & Microwaves , and Physics Today , plus others.
Consider these items as online extras, and worth a look. (Please note: there are also links to the previous weeks' editions, in the “Navigate” box to the right.)
