Geiger Backpack is a device that measures ambient radioactivity and GPS position and saves them on a cloud database using your smartphone as a WiFi hotspot. Our project is a portable device powered by an Intel Edison and equipped with a GPS receiver and a Geiger Tube, a sensor able to detect radioactivity. Our device […]
2.5V-4.2V input to 3.3V output – 1A Buck Boost Converter using LTC3441
https://www.electronics-lab.com/project/2-4v-5-5v-input-3-3v-output-1-2a-buck-boost-converter-using-ltc3441/
This circuit can produce an output of 3.3V and 1A current continuously for a voltage input varying from 2.5V to 4.2V. The LTC3441 is a high efficient buck boost converter which plays a vital role in portable instrumentation because of its fixed frequency operation. This circuit produces the output from a single Li-ion battery. Multiple […]

chipKIT Tutorial: Using Nokia 5110 LCD
https://www.electronics-lab.com/chipkit-tutorial-using-nokia-5110-lcd/
Raj @ embedded-lab.com has posted another great tutorial on how to interface a Nokia 5110 LCD to chipKIT board. Today, we will see how to connect a NOKIA 5110 graphical LCD (used in Nokia 5110 cell phones), which is a 84×48 pixel monochrome display of about 1.5″ diagonal in size. The display can be used for […]
Creating G-Code via EAGLE software
https://www.electronics-lab.com/creating-g-code-via-eagle-software/
Boris Landoni shows us how to create G-Code using Eagle PCB design software: To create a PCB with 3Drag , by milling , it is necessary to have the G-Code files for the tracks patterning and for the holes relating to the printed circuit board itself. In this section we describe how to obtain these […]
LTC3643 – 2A Bidirectional Power Backup Supply
https://www.electronics-lab.com/ltc3643-2a-bidirectional-power-backup-supply/
Linear Technology Corporation introduces the LTC3643, a bidirectional, high voltage boost capacitor charger that automatically converts to a buck regulator for system backup. The proprietary, single-inductor topology with integrated PowerPath™ functionality does the work of two separate switching regulators, reducing size, cost and complexity. The LTC3643 operates in two modes – boost charge mode and […]
Arduino Tutorial: Using a Servo SG90 with Arduino
https://www.electronics-lab.com/arduino-tutorial-using-a-servo-sg90-with-arduino/
educ8s.tv shows us how to use a servo motor with Arduino UNO: A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. That’s why we need the Arduino, in oder to send that signal to the servo. Servos […]
