Arduino-Powered Laser Engraver
https://www.electronics-lab.com/arduino-powered-laser-engraver/
MichielD99, a 16 year old Belgian teenage maker build this amazing laser engraver using Arduino UNO, two NEMA-17 stepper motors and stepper motor drivers. This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this […]
Simple Arduino SD-Card GPS/NMEA Datalogger
https://www.electronics-lab.com/simple-arduino-sd-card-gpsnmea-datalogger/
KF5OBS @ jaunty-electronics.com shows us how to build a minimalistic GPS datalogger. The GPS logger is based on the Arduino platform and stores raw NMEA sentences from pretty much any GPS module to a SD card. For a project I needed to log GPS information. I had various GPS modules and plenty of Arduinos laying […]

Home energy monitoring using Nucleo and Raspberry Pi
https://www.electronics-lab.com/47049-2/
TSalwach @ github.com build a 3-phase home power meter system. A STM32F072RB MCU on Nucleo evaluation board make measurements and Raspberry Pi 1 collects data and share via web interface. I want to have real time power measurement of my home in my smartphone. I’ve got one some long time ago, it was counting time […]

Sparkfun: First Impressions of the ESP32
https://www.electronics-lab.com/sparkfun-first-impressions-of-the-esp32/
Jimb0 @ sparkfun.com takes a first look on the new ESP32 WiFi board by Espressif that’s an improvement of the ESP8266 board. The ESP32 doesn’t replace the ESP8266, but it does improve on it in every aspect. Not only does it have WiFi support, but it also features a Bluetooth 4.2 radio, making it even […]
SCIO: The Fun New Way To Learn Coding, Computers and STEM
https://www.electronics-lab.com/scio-the-fun-new-way-to-learn-coding-computers-and-stem/
A new board that aims to fill an education gap for programmable boards is on kickstarter. SCIO enables anyone, without the need of previous experience, to experiment with electronics and coding and build various projects based on onboard sensors, work on the cloud, make light shows and even more. Within an hour of opening the […]
A new form of retina implant returns sight to the blind
https://www.electronics-lab.com/bionic-eye-returns-sight-to-the-blind/
A team of scientists at Oxford Eye Hospital aim to create a bionic eye, that will make people who lost their sight to see again. A special chip is placed behind the retina and a small processor sends signal to the optic nerve and brain process it thus enabling the person in treatment to see. In […]
Lithium-Ion Battery Warms Up, Operates In Subzero Temperatures
https://www.electronics-lab.com/lithium-ion-battery-warms-up-operates-in-subzero-temperatures/
Charles Q. Choi @ spectrum.ieee.org discuss about a new type of li-ion battery able to work in low temperatures. A new “all-climate” lithium-ion battery can rapidly heat itself to overcome freezing temperatures with little sacrifice in energy storage capacity and power, researchers say. This advance might enable applications for which high-performance batteries are needed in […]
