![]() He cleverly attached a barograph to pendulum, which allowed him to control the arc of the pendulum swing, depending on the changes of the barometric pressure. Since the basement was almost a climate controlled environment, it turned out that the accuracy of the pendulum swing was only affected by barometric pressure. He built the whole thing from scratch and continued to perfect it for about 3 decades!Įvery 30 seconds, the pendulum would get a slight 'push' from a relay actuated escapement to compensate for air resistance (friction or drag). I recall my father (who was an ME) crafted about a 6foot tall pendulum clock in our basement. Such clever designs/creations are truly a labor of love! He has also planned, written, and presented online courses on a variety of engineering topics, including MOSFET basics, ADC selection, and driving LEDs. He has a BSEE from Columbia University and an MSEE from the University of Massachusetts, is a Registered Professional Engineer, and holds an Advanced Class amateur radio license. Before those roles, he was at Instron Corp., doing hands-on analog- and power-circuit design and systems integration for materials-testing machine controls. Prior to the marcom role at Analog, Bill was Associate Editor of its respected technical journal, and also worked in its product marketing and applications engineering groups. At Analog Devices, he was in marketing communications as a result, he has been on both sides of the technical PR function, presenting company products, stories, and messages to the media and also as the recipient of these. In past roles, he worked as a technical website manager for multiple EE Times sites and as both Executive Editor and Analog Editor at EDN. ![]() Sun angle sensor simplifies integrationīill Schweber is an electronics engineer who has written three textbooks on electronic communications systems, as well as hundreds of technical articles, opinion columns, and product features.Simple Product, but Subtle Troubleshooting.A Century Ago, Einstein’s General Relativity Solved an Orbital Measurement Discrepancy.After all, who thought that subatomic-level experiments of the 1930s investigating magnetic moments of an atom’s nucleus and how the nucleus tends to align either parallel or anti-parallel to an external magnetic field, and how it absorbs or emits radio waves when exposed to a sufficiently strong magnetic field, would lead to the development of MRI (magnetic resonance imaging) forty years later-a case where a sub-microscopic phenomena leads to very macroscopic results (see here for more details on both).Īre there any “how did they think of that” things that you’ve seen, that made you stop, wonder, and then look in wonderment? Of course, even they often don’t know where these ideas and building-block steps will lead. ![]() That’s what engineers, scientists, and even some artists do: they have an idea and work through its twists and turns.
