Using an Electromagnet to Drive the Bobble Replacing batteries in non-rechargeable devices is expensive. When I built personalized bobbleheads for my grandchildren, I decided to make them solar-powered. Here’s a description of their electromagnetic actuation and simple circuitry. Bobbleheads, sometimes called wobbleheads, have been with us for more than 200 years. They were popular in […] The post Build a Solar-Powered Bobblehead appeared first on Circuit Cellar ..read more

Based On the Raspberry Pi Compute Module 4 After a few years during which all Raspberry Pi boards were unavailable to me, I was interested in getting my hands on a line of modules made by EDATEC that are based on the Raspberry Pi CM4 module. Here’s the review. EDATEC is a Raspberry Pi partner […] The post Evaluating EDATEC’s Line of Industrial Modules appeared first on Circuit Cellar ..read more

Time is of the Essence Digital signal processors (DSPs) and digital signal controllers (DSCs) are designed for time-critical execution of complex algorithms. These chips are crucial to many high-end, high-performance applications today. Digital signal processors (DSPs) and their cousins, digital signal controllers (DSCs), are microprocessors optimized for, well, digital signal processing. That is, they’re built […] The post DSPs and DSCs appeared first on Circuit Cellar ..read more

Recursion is a method of solving problems in computer programming that involves functions which call themselves. This concept might seem a bit odd the first time you hear it, but once you wrap your head around it you will find it a useful tool. It is best suited to solving problems that break down into […] The post Recursion appeared first on Circuit Cellar ..read more

Apocalypse Now? THE DARK SIDE Robot Doomsday, also known as the Droid Desolation or the AI Armageddon, is here. Frankly, as a long-time fan of dystopian science fiction, I really thought that the dawn of the decline of human supremacy would be more dramatic. To paraphrase the now classic anti-war movie Apocalypse Now: “This is the […] The post Robotics in Manufacturing appeared first on Circuit Cellar ..read more

Siemens has developed one of the world’s most innovative circuit protection devices with cutting-edge electronic switching technology. SENTRON ECPD (Electronic Circuit Protection Device) electronically switches off circuit faults if errors occur and, if necessary, trips the mechanical isolating contact downstream. Up to now, disconnection was handled purely through electro-mechanical elements. “This innovation offers a variety […] The post Siemens Introduces One of the World’s Most Innovative Circuit Protection Devices appeared first on Circuit Cellar ..read more
