Hardware Protection – OverVoltage and OverCurrent
https://www.electronics-lab.com/hardware-protection-overvoltage-and-overcurrent/
Maurizio @ dev.emcelettronica.com discuss about the different aspects of protecting power supplies from overvoltage and overcurrent. Power processing is one of the most important aspects on electronic design. The power is unique for a typical system because it gives the system life. Before starting to make the project for a power supply we need to analyze […]
Basic Types of Transistors
https://www.electronics-lab.com/article-basic-transistor-types/
In this article we will review the basic transistor types and their function. We will cover bipolar transistor, Junction FET, MOSFET and UJT transistor types. Feel free to comment with other transistor types you know. Bipolar Transistor Bipolar transistors are three terminal devices and act like electrically controlled switches of as current/voltage amplifiers. They come […]
Ultrasonic Atomizer
https://www.electronics-lab.com/ultrasonic-atomizer/
This reference design is a simple ultrasonic atomizer that helps fight against respiratory diseases. Atomizer is like nebulizer, it is just that nebulizer takes time to deliver liquid to mist. However, both undergo almost the same process. This medical ultrasonic atomizer circuit is composed of power supply circuit, ultrasonic oscillator and atomizer circuit. It specifically […]
nodeLHC – ESP8266 development board
https://www.electronics-lab.com/nodelhc-esp8266-development-board/
Pedro Minatel shared us his ESP8266 development board project – nodeLHC: This board was developed at the Campinas Hacker Lab in Brazil during our weekly IoT meetings. This layout and schematic was developed by Leandro Pereira. The idea was to develop a easy to use board and to learn how to use this magnificent WiFi […]

In this video I am uploading a simple blink to two esp8266 development boards. Using Arduino Ide to upload code to ESP8266 – [Link]
Get rid of unpleasant odors easily and effectively
https://www.electronics-lab.com/get-rid-of-unpleasant-odors-easily-and-effectively/
USM-MEMS-VOC module evaluates rate of air pollution by contaminants such as cigarette smoke and cooking odors and allows control of air ventilation system on demand. Modul USM-MEMS-VOC is based on the innovative and highly stable TGS 8100 MEMS semiconductor sensor TGS8100 from Figaro. In the presence of detectable gas, sensor resistance decreases depending on gas […]
Overheat/Overcooling Circuit Breaker
https://www.electronics-lab.com/overheatovercooling-circuit-breaker/
This project automatically switches off the electrical flow in event of excess heating or excess cooling thus protecting the circuit from damage using NXP NCX2220GU. The comparator guarantees to operate at low voltages which makes this device convenient for use in 5 V systems and has a typical internal hysteresis of 9 mV that allows […]
LSM6DS3H – New 6-axis motion sensor from STMicroelectronics
https://www.electronics-lab.com/lsm6ds3h-new-6-axis-motion-sensor-from-stmicroelectronics/
by Martin Cooke @ elektormagazine.com: The latest MEMs device from STMicroelectronics is said to be the world’s most advanced six-axis motion-sensor device designed to support image stabilization in smartphones, tablets and digital still cameras. The LSM6DS3H combines a 3-axis gyroscope and 3-axis accelerometer together with an Ultra Low Power processing IC to provide a System in […]
Temperature controlled coolbox
https://www.electronics-lab.com/temperature-controlled-coolbox/
by nusnel @ instructables.com: For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to […]
Arduino Time-Lapse Panorama Controller
https://www.electronics-lab.com/arduino-time-lapse-panorama-controller/
by oliverb @ instructables.com: The Arduino controls a Geared Stepper Motor 28BYJ-48 via a ULN2003 Stepper Motor Driver Board. The 4×20 I2C LCD display and 5 micro switches form the interface to the Arduino. The controller has a Manfrotto 200PL-14 quick release tripod mount for attachment to my tripod and other mounting hardware fitted with a […]
