Hot glue guns are pretty simple beasts: there’s an on/off switch, a heating element, and a source of current, be it battery or wired. You turn it on, and the heater starts warming up; ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

3D printing is expanding in many sectors, boosting its growth and investment appeal. Focus on companies improving their profitability and expanding market reach in 3D printing. Investing in ...

James has been writing about technology for years but has loved it since the early 90s. While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser ...

Saw this old couple at the park last weekend. Hands locked after decades together. Love lasts but little things grind on guys quiet like. Pulled these from buddy rants at the bar, my own screw ups, ...

"Windup" occurs when the integral term grows indefinitely while the actuator is saturated (at max limit). Standard PID calculates d(Error)/dt. This library calculates ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

This project implements an Arduino-based autonomous line following robot using IR sensors and PID-based speed correction for smooth and accurate path tracking. IR ...
