One case – over 100 possibilities of usage
https://www.electronics-lab.com/one-case-over-100-possibilities-of-usage/
We speak about the practical case CTK110EU full of high quality CrV tools sufficient for majority of common operations. CTK110EU tools set might be easily called as “all-in-one”. Naturally, such all-in-one solution won´t help in all situations which we may face at production or servicing, but very probably it is more than suitable for a […]
Laser Data Transmission
https://www.electronics-lab.com/laser-data-transmission/
Lasers have been one of the essential technologies used in industries. It is realized that light outperforms radio in terms of speed and density. It has been used for communications whether in scanning barcodes, reading CD’s and DVD’s. This design is a simple data transmitter that uses a DIP switch to support the transmission of […]

Ilia Baranov has designed a reference business card: Back of card includes: Ruler in both 1/10″ and mm. AWG Hole size gauge (not super accurate due to plating, but that is unavoidable) Resistor/capacitor/inductor/diode sizes Common surface mount component sizes Common electrical symbols and shortcuts/equations Common conversions Trace size comparison Quote from Dune! Making a PCB […]
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 […]

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 […]
