In the early 2000s, the idea that you could write programs on microcontrollers that did things in the physical world, like run motors or light up LEDs, was kind of new. At the time, most people ...

At the end of a revolution, it triggers a hall sensor which resets the circuit. The best thing about this design? It’s been in service for ten years. [Larry’s] original video is a big contrast ...

A hobbyist assessed CNC lead screw accuracy by building a setup using digital calipers interfaced with a Raspberry Pi. These calipers transmit data via a 76 kbps synchronous serial protocol, requiring ...

Abstract: This paper discusses the behavior of oscillators with multiple-resonant circuits. It discusses the condition for free-running stable oscillations, the injection locking phenomena, the stable ...

Creating a GPS tracker is an exciting project, especially for beginners interested in electronics and software development. It’s a project that… ...
