5V @ 3A Power Supply using TPS54302
https://www.electronics-lab.com/project/5v-3a-power-supply-using-tps54302/
This circuit is based on TPS54302, a high efficient buck converter from Texas instrument. The input range for this circuit varies between 4.5V to 28V and it can produce an output voltage of 5V. Over voltage protection and over current protection are the two major advantages of this device. Features Input(V): 4.5VDC to 28VDC Output(V): […]

Panelization – using GerberPanelizer on Windows
https://www.electronics-lab.com/panelization-using-gerberpanelizer-windows/
Arsenijs over at Hackaday.io explains how to panelize PCBs using GerberPanelizer on Windows. He writes: This tutorial was done on Windows. Authors claim it could also be used on Linux by using Mono, but I haven’t tried and don’t understand a lot about Mono to see what could be done. I am switching to Linux nowadays, so […]

Artificial Magnetic Fields For Photons
https://www.electronics-lab.com/artificial-magnetic-fields-photons/
Photons became a hot research topic due to their important role in holding data across long distances. Starting from the fact that photons are insensitive to magnetic fields which concludes to their disability to process data, a group of researchers from the ETH (Eidgenössische Technische Hochschule) in Zürich are trying to make photons controlled with electric fields […]
Fiducial Marks in PCBs – What they are?
https://www.electronics-lab.com/fiducial-marks-pcbs-noticed/
In the past, I’ve always seen small circuits of copper with no silk screen or solder mask on top of it and as a PCB designer I have always the question in my mind: What is it for? — I’ve never needed them before! As I can find them in Arduino’s PCBs as well, I […]

XOD, Visual Coding For Microcontrollers
https://www.electronics-lab.com/xod-visual-coding-microcontrollers/
XOD is a new visual programming language for microcontrollers launched now. Pronounced [ksəud], this programming language idea was inspired by vvvv, a hybrid visual/textual live-programming environment for easy prototyping and development which is designed to facilitate the handling of large media environments with physical interfaces, real-time motion graphics, audio and video that can interact with many users simultaneously. Like Code, […]
