How to Set Up WiFi on the Raspberry Pi
https://www.electronics-lab.com/set-wifi-raspberry-pi/
circuitbasics.com show us how to setup a Wifi dongle using SSH connection. Now I’ll explain how to use that SSH connection to setup a WiFi dongle so you can run your Raspberry Pi wirelessly from a remote desktop application. This is a really useful way to set up your Raspberry Pi, because you will be […]
Soft Latch Power Switch Circuit
https://www.electronics-lab.com/soft-latch-power-switch-circuit/
Dаvid Jones through his Youtube channel EEVblog described in detail how to design a cheap soft latch power switch circuit, using one push button switch to toggle your circuit power on and off with the following design requirements: Zero power when off. One on/off switch. Standalone(no MCU). General components only (Diodes, Transistors, ..ect). Minimal parts. […]
New Alcohol Monitoring System from University of California, San Diego
https://www.electronics-lab.com/new-alcohol-monitoring-system-university-california-san-diego/
A new alcohol monitoring system from UCSD consists of a temporary and one-time use tattoo that clings to the human skin and a flexible electronic board that attaches to the tattoo magnetically transfers the results of sensing the blood alcohol concentration via Bluetooth to a smart device paired with it. The UCSD researchers tried to […]

An Atmega library for multiple HD44780 LCDs
https://www.electronics-lab.com/atmega-library-multiple-hd44780-lcds/
Davide Gironi has posted an I2C multiple HD44780 AVR Atmega library: This library implements a driver for HD44780 lcd connected through PCF8574 port expander. Data is transmitted using only 2 wire over i2c with the PCF8574. This library can drive up to 8 LCD concurrently. Lcd driver is based upon Peter Fleury’s lcd driver HD44780 […]
DIY PCB inspection microscope
https://www.electronics-lab.com/diy-pcb-inspection-microscope/
Saulius made a DIY PCB inspection microscope and wrote a post on his blog about it: Despite how good microscope you have, stand is still very important part of final assembly. And while there are many commercial ones made of cast iron, they might cost more than a microscope head itself. I decided to make stand from […]
