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 […]
Battery Powered Frequency Meter (0 to 20kHz)
https://www.electronics-lab.com/battery-powered-frequency-meter-0-to-20khz/
The circuit is a simple digital frequency meter that is made of a frequency-to-voltage converter and an analog-to-digital display converter that can be operatedfrom a single 9-volt battery. The TC7126 ADC generates the voltage required by the TC9400 FVC with internal regulators. The TC7126 is designed to directly drive a 3-1/2 digit, non-multiplexed LCD display […]
