A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but ...

Abstract: This work proposes the use of a high-frequency resonant LLC DC/DC converter with PWM dimming to power an array of LEDs for automotive headlight applications. The resonant tank is designed ...

Raspberry Pi MicroSD Card (32GB or larger) MicroUSB Cable (data-capable) Computer with Windows, macOS, or Linux and internet access Now you are all set! The app is straightforward. You can either send ...

The TrooperAI project was a test to see if I could build a low-latency, local (non-networked) voice assistant in Python for the Raspberry Pi. The system combines real-time speech recognition, ...

A quiet idea from 1914 still shapes new science. A young Srinivasa Ramanujan once shared bold pi equations. Today those same lines guide hard work in physics. A fresh study now links his ideas to ...

Abstract: Regarding significant harmonics from the grid voltage side, a control strategy for a three-phase pulsewidth modulation (PWM) rectifier without alternating current (ac) voltage sensor based ...
