Wow, does that ever bring back memories! Scroll back 50 years - "Instant-On" really was a marketing term for series-string vacuum tube radio and TV sets. A silicon diode across the on/off switch in reverse to the main B+ rectifier would keep the tube heaters at half-power by rectifying the AC so only half-cycles could get through. But this kept the tubes hot enough to start immediately when the diode was shunted by the switch, even though it did take a few more seconds to reach optimum performance. It worked, but was a terrible waste of power.
Back then the marketeers were tripping all over each other in efforts to come up with ever-more creative claims for the audio output wattage of hifi/stereo audio amplifiers. Can anyone top "Peak-to-Peak Music Power!"? The USA FTC (Federal Trade Commission) put a stop to that nonsense in 1974.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
