danielrp @ instructables.com build a nice power supply for his lab. He writes: From my point of view one of the best ways to get started in electronics is to build your own laboratory power supply. In this instructable I have tried to collect all the necessary steps so that anyone can construct his own. […]
Real Time Clock On 20×4 I2C LCD Display with Arduino
https://www.electronics-lab.com/real-time-clock-20x4-i2c-lcd-display-arduino/
Sometimes it may be necessary to use a display while making a hardware project, but the size and the type of the display may vary according to the application. In a previous project, we used a 0.96″ I2C OLED display, and in this project we will have an I2C 20×4 character display. This tutorial will describe […]

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 […]
