Some events you attend, and some events you feel the moment you walk through the doors. The Rand Show 2026 was the latter, ...

With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...

LEGO train modeling, also known as L gauge railroading, blends creativity, engineering, and nostalgia into a uniquely ...

Periwinkle's family is still wondering how she managed to travel dozens of miles on her own. Hit-and-run victim dies in the hospital, police search for his family and the driver A man who was struck ...

On This Is My Thing, our continuing mission is to talk with people about the things they do just for themselves – not because it’s their job and not because it’s a responsibility, just because they ...

Abstract: In this paper, an improved finite control set-model predictive control strategy for four-level nested neutral point clamped (4L-NNPC) converters is proposed. Compared with two-level ...

Abstract: This article presents a continuous control-set model-predictive control (CCS-MPC) for speed regulation of a series dc motor powered by a dc–dc converter (buck or boost converter). The ...

Logging railroads — with their unorthodox infrastructure and equipment — have always fascinated enthusiasts, especially as they navigated the rough terrain of North America to haul timber. This ...

From Portland, Ore., to New Orleans, all along the Golden Crest, you certainly won’t go wrong modeling the Southern Pacific. Choosing from the vast range of eras and locations during the railroad’s ...

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...
