Nixie thermometer
https://www.electronics-lab.com/nixie-thermometer/
Luca Dentella has build a Nixie thermometer to measure the temperature of the liquid cooling system, file are available on Github. I decided to log the design and the development of the project in ten blog posts. They show my “divide et impera” approach: I divided the whole project in small tasks (drive a nixie […]

Organic solar cells set new efficiency record
https://www.electronics-lab.com/organic-solar-cells-set-new-efficiency-record/
The German company Heliatek has developed new OPV multi-junction solar cells with an efficiency of 13.2%. This is a world record for organic solar cells. Thanks to the excellent low light and high temperature behavior of the organic semiconductor, the electricity generation of the newly developed cells corresponds to the output of conventional solar cells with […]
Easily measure diode capacitance and reverse recovery
https://www.electronics-lab.com/easily-measure-diode-capacitance-and-reverse-recovery/
Glen Chenier @ edn.com wanted to find out the characteristics of an unknown diode to be able to replace it with an equivalent one so he decided to make some measurements using his test equipment. In this article he show us how to measure the junction capacitance, Cj, and reverse recovery time Trr of a diode using […]
5V to 12V @1.2A regulated power supply using LM2587
https://www.electronics-lab.com/project/5v-to12v-1-2a-regulated-power-supply-using-lm2587/
This circuit is based on LM2587, a simple boost converter from Texas instruments. It produces a 12V regulated output for a input of 5V. It can also be used as a multiple output regulator, forward converter and as a flyback regulator. This regulator requires minimum number of external components, which makes it cost effective. Features […]
Record-setting flexible phototransistor revealed
https://www.electronics-lab.com/record-setting-flexible-phototransistor-revealed/
Researchers at the University of Wisconsin-Madison have revealed a unique phototransistor that is flexible and faster and more responsive than any similar phototransistor. The innovative phototransistor could improve the performance of myriad products — ranging from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites — that rely on electronic light sensors. Integrated […]
Weather Station Project with ATMEGA328P, DHT22, BMP180, BH1750 and a Nokia 5110 LCD
https://www.electronics-lab.com/weather-station-project-with-atmega328p-dht22-bmp180-bh1750-and-a-nokia-5110-lcd/
This is an Arduino powered Weather Station Project that can run on batteries for almost a year! In order to achieve that we use a bare ATMEGA328 chip along with some accurate sensors. We use the DHT22 temperature and humidity sensor, a BMP180 barometric pressure sensor, a BH1750 light intensity sensor and a Nokia 5110 […]
