https://www.electronics-lab.com/researchers-develop-transparent-flexible-terahertz-sensors-with-graphene/
The researchers of the Swedish Chalmers University of Technology have developed a new design of terahertz sensor using Graphene. This flexible sensor can be integrated into wearable materials. Most importantly, it can be manufactured very cheaply and also it is practically transparent. This new type of sensor could be a major breakthrough by opening doors of many new applications. The […]
MetCal Connection Validation – The Next Generation of Soldering
https://www.electronics-lab.com/metcal-connection-validation-next-generation-soldering/
Making solid connections between electrical components on a board is an important part of many hardware projects. A good solder joint forms an alloy at the surface of the PCB and the component lead. During soldering, a solder connection on a circuit board can quickly turn into a real nightmare if not caught immediately, ending […]
Arduino Real Time Clock with DS1302 and Nokia 5110 LCD Display
https://www.electronics-lab.com/arduino-real-time-clock-ds1302-nokia-5110-lcd-display/
Hi guys, in one of our previous tutorials, we made a real time clock, using the DS3231 RTC Module and the 1602 LCD display module. For this tutorial, we will be building something similar using the DS1302 RTC module and the Nokia 5110 display module. Unlike the 1602 LCD module which was used in the […]

Printed circuit board manufacturer – JLCPCB Review
https://www.electronics-lab.com/printed-circuit-board-manufacturer-jlcpcb-review/
Recently, I had the opportunity to test the printed circuit boards (PCB) offered by JLCPCB. These tests were made in two different boards of the brand and here I’ll report my impressions about them. Due to the spread of the maker culture and the do-it-yourself (DIY) and easy access to components and a huge amount […]
A Temperature Logger to Protect Sea turtles
https://www.electronics-lab.com/temperature-logger-protect-sea-turtles/
Data loggers are small, battery-powered devices used to sense and store information in different situations. They include a microprocessor, data storage, one or several sensors and they can record information for a very long period. However, some data loggers do not include sensors, but have ports that allow a sensor to be connected. They are […]
Angle Sensing with Circular Vertical Hall Technology
https://www.electronics-lab.com/angle-sensing-circular-vertical-hall-technology/
Angle sensing has always been challenging particularly in industrial and automotive environment because of the need for precise and accurate sensing at high speeds. Allegro Microsystems developed the A1330 an integrated circuit angle sensor that works based on magnetic Circular Vertical Hall (CVH) technology. Unlike other angle sensors Allegro’s A1330 does not require a concentrator […]
