This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed ...

Using a single microcontroller port to drive a multi-digit LED display to help engineers with those last-minute design ...

One of the joys of writing for Hackaday comes in following the world of new semiconductor devices, spotting interesting ones ...

The Nintendo Switch 2 supports a wide range of controllers, from Nintendo’s own Pro Controller to many Bluetooth gamepads you might already have. Whether you’re setting up your new console for the ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

The crash on Jan. 29 left 67 people dead. The U.S. government admitted some failures and accepted liability for its role in the deadly Jan. 29 mid-air crash over the Potomac River between a commercial ...

Abstract: The conventional model reference adaptive system (MRAS) employs a proportional-integral (PI) controller with a low-pass filter (LPF). However, the LPF and integrator add phase delay and DC ...

Abstract: In this study, we propose a modified model predictive control (MMPC) approach combined with an adaptive second-order disturbance observer (ASDO) for efficient speed control of permanent ...
