Pixel 2.0, Arduino Zero-Like Board With Smart Display
https://www.electronics-lab.com/pixel-2-0-arduino-zero-like-board-smart-display/
The Pixel is an Arduino-compatible smart display, combining a 32-bit Cortex M0+ MCU with 32K of RAM, a 1.5″ 128×128 color OLED screen, and a microSD slot all in one package. This is Rabid Prototypes’ second iteration of Pixel, which originally raised nearly $10,000 on Kickstarter back in 2015. The board offers a number of […]
Raspberry Pi I2C LCD Set Up and Programming
https://www.electronics-lab.com/raspberry-pi-i2c-lcd-set-programming/
In this video Circuit Basics show us how to use I2C to connect an LCD to the Raspberry Pi. After showing you how to connect the LCD to the Pi with a PCF8574 (http://www.circuitbasics.com/pj6v), they show you how to program it. First I’ll cover the basic stuff like printing text to the screen, clearing the […]

Motion sensor offers low-power settings
https://www.electronics-lab.com/motion-sensor-offers-low-power-settings/
Susan Nordyk @ edn.com writes: Small enough for wearable devices, STMicroelectronics’ LIS2DW12 three-axis accelerometer draws only 50 nA in standby mode and 380 nA in low-power mode at a 1.6-Hz output data rate, adding negligible load on the battery. Operating from a supply voltage of 1.62 to 3.6 V, the LIS2DW12 enables extended operation from […]

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 […]
