Being a Sci-Fi geek, I am a fan of the late 1950’s Hollywood “cheesy” low budget Ed Wood movies typical of this genre. One of my favorite films is “Plan 9 from Outer Space,” in which aliens come to Earth to stop humanity from building a doomsday weapon that could destroy the entire universe. However,
The term “hot swap” refers to the practice of inserting or removing modules from a powered system. Hot-swap controllers are sometimes categorized together with power distribution switches; however, there are key differences that must be understood for proper system design. A hot-swap controller uses an external
The Internet-of-Things (IoT) is simply the concept of connecting any device with a sensor or controller to the Internet (and/or to each other). This includes everything from cell phones, appliances, cars machines, components of machines, wearable devices and anything else you can think of. But the principle
