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. Please note : our backlog queue for both sections has grown much faster than we're listing them, so we're running more of them each week to clear the backlog (for now).
“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 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 , Portable Design , and Physics Today , plus 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).
