Wireless digital scale
https://www.electronics-lab.com/wireless-digital-scale/
This is a wireless digital scale using ATTiny85 microcontroller and HM-10 Bluetooth low energy transmitter/receiver: This scale is wireless. It may be useful where you can’t operate a normal scale, due to the weather outside, or if you don’t want to scare birds or other creatures away. With this scale you can weigh them. In […]

ESP8266 Desktop Clock – WiFi Synchronised
https://www.electronics-lab.com/esp8266-desktop-clock-wifi-synchronised/
This project is a wifi synchronised desktop clock using 7-segment displays. The heart of the project is a ESP8266 board. The ESP8266 is a awesome chip; with integrated WiFi, 80MHz clock speed, total 160kb RAM, 512kb of flash memory, and a ton of other features, it makes a regular Arduino look like a joke. The […]
How to measure temperature very accurately with an Arduino
https://www.electronics-lab.com/measure-temperature-accurately-arduino/
This project shows how to measure temperature data from a TSYS01 Temperature Sensor board using Arduino: While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple boxes were to be built and used in a research […]
Sensing current on the high side
https://www.electronics-lab.com/home-community-blogs-benchtalk-sensing-current-high-side/
Michael Dunn@ edn.com discuss about current sense on the high side of power source. At their heart, the majority of DC current sense circuits start with a resistance in a supply line (though magnetic field sensing is a good alternative, especially in higher-current scenarios). One simply measures the voltage drop across the resistor and scales […]
Eagle CAD Tips and Tricks Part 2
https://www.electronics-lab.com/eagle-cad-tips-tricks-part-2/
This is the second and final article of the Eagle Tips from allaboutcircuits.com: Before searching on the internet for new libraries to add to Eagle, first make sure that your device does not already exist in your local libraries. To check, use a search pattern that includes ‘*’. For example, if you want to add a […]
Egg Memristor recipe (serves one)
https://www.electronics-lab.com/egg-memristor-recipe-serves-one/
by Clemens Valens @ elektormagazine.com discuss about a new type of dissolvable memory resistor using egg proteins. Over the past years research has been done with several biodegradable materials, including DNA, to make what is called transient electronics, dissolvable electronic components that are designed to be compatible with the environment. The Chinese scientists used egg […]
