Simple 3 phase Arduino energy meter
https://www.electronics-lab.com/simple-3-phase-arduino-energy-meter/
Simple 3 Phase Arduino energy meter from The DIY Life: Again, with this meter I was going for simplicity. Sure, for perfectly accurate measurements you need to measure both the supply current and voltage but for this application and in the interests of keeping the energy meter simple and safe – only requiring a non-contact […]

The New Arduino 101 (Genuino 101) – Unboxing, Set Up, and Comparing it to the Arduino Uno
https://www.electronics-lab.com/new-arduino-101-genuino-101-unboxing-set-comparing-arduino-uno/
Arduino’s newest board, the Arduino 101 is finally here… It has an Intel Curie processor, and an on-board gyroscope, accelerometer, and Bluetooth. Let’s see how it stacks up to the Uno, and find out what each of the components on the board do. At the end of the video, I go through setting it up […]
Flow battery can run for 10 years with zero maintenance
https://www.electronics-lab.com/flow-battery-can-run-10-years-zero-maintenance/
by Jan Buiting @ elektormagazine.com: Harvard University researchers have developed a low-cost flow battery that stores energy in organic molecules dissolved in neutral pH water. In their report (see below) they claim that the new battery can run for a decade or more without maintenance. Flow battery can run for 10 years with zero maintenance […]
1.2V-32V @3A Variable Switching Regulator using LM317
https://www.electronics-lab.com/1-2v-32v-3a-variable-switching-regulator-using-lm317/
The circuit presented here is based on LM317. Generally, LM317 is known as a linear regulator IC, but here the circuit operates as a switching regulator. This circuit operates by transferring energy from the input to the output by using a solid state switch. Power Efficiency of a switching regulator is much higher than the […]
Better current with spin electronics
https://www.electronics-lab.com/better-current-spin-electronics/
by Clemens Valens @ elektormagazine.com The ongoing miniaturisation of electronics is expected to reach its limits in the near future. One of the limitations is the size of electrons that are needed in electronic circuits to transport charge from one place to the other, what we usually call ‘current’. To work around this problem a […]
FONA808 USB Interface
https://www.electronics-lab.com/fona808-usb-interface/
Jesus @ jechavarria.com tipped us with his latest project. He writes: For several months I’m working with FONA808 modules from Adafruit to make a portable, web-based locating system. This modules are based on the SIM808 module from SIMCOM manufacturer, and integrates both GSM and GPS transceivers in one 24x24mm package. The Adafruit board includes this […]
Hack Your Car With Macchina M2
https://www.electronics-lab.com/hack-car-macchina-m2/
Car hacking applications have been growing during the last few years, making it faster and cheaper to get into automotive tinkering. A new device was launched recently on kickstarter called M2 by Macchina. M2 is an open-source, versatile development platform which can be wired under the hood for a more permanent installation or plugged into the […]
Installing The Micronucleus Bootloader To An ATtiny Via Arduino
https://www.electronics-lab.com/installing-the-micronucleus-bootloader-to-an-attiny-via-arduino/
In order to be able to upload Arduino sketches directly to the ATtiny84 over USB without the need to use a programming device, Shawn Hymel, an electrical engineer at Sparkfun Electronics, had published a guide showing how to install the micronucleus bootloader, which supports virtual USB (V-USB), onto an ATtiny84 using Arduino. The Atmel AVR […]
