Algorithmic Robotic Golf Club Masters Complex Mini-Golf Shots Engineer and creator Shane Wighton has upgraded his robotic mini-golf system to tackle complex, physics-heavy shots with near-perfect accuracy. The project combines a motorized golf club with a full motion-capture setup, allowing the system to precisely track the ball, club, and course geometry. By scanning real-world mini-golf layouts into a digital model, the system can analyze terrain… |

This Clock Displays Time Using Air and Pneumatic RAM A unique experimental clock created by soiboi soft is gaining attention for its unusual way of telling time. While it may look like a fully air powered system, the design actually combines pneumatic logic with electronic control. Instead of relying only on circuits and chips, the clock uses air pressure to form its display, while electronics handle precise timing and control, making it a… |

Build a Simple Optocoupler Tester Circuit for Fault Detection Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials… |

GST Council’s 56th Meeting: What the ELCINA Webinar Revealed for the Electronics Industry The GST is a framework that was specifically introduced to harmonize taxation across India. However, over the years, it has somehow evolved into a complex system that businesses, particularly small and medium-sized ones, struggle to navigate. We are now about to witness one of the most drastic changes GST has seen since its inception as the government attempts to… |

REF67004 is ROHM's New Power Supply Design that Combines Analog and Digital Control Traditional analog power supplies struggle to keep up with today’s performance and control accuracy requirements, which have gotten way stricter. Even though digital power supplies work better, they’re just too expensive and use too much power for smaller industrial applications. This makes their use limited. To counter this, ROHM has just announced a new reference design for power supply… |
