limpkin @ limpkin.fr tries out the CDM324 / IPM165 Doppler effect sensor and proposes an amplification circuit to get the readings out of the sensor. He writes: You may recall the article I wrote a couple of years ago about a nearly identical Doppler sensor, the HB100. While the...

MKRFOX1200 is a powerful board that combines the functionality of the Zero and SigFox connectivity. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking having a low power device. Arduino MKRFOX1200 has been designed to...

David Johnson-Davies @ technoblogy.com writes: This article describes how to get up to two 10 or 12-bit digital-to-analogue outputs from an 8-bit Timer/Counter, such as in the ATtiny85. To test the routine I built a circuit which allows you to vary the brightness of two LEDs with two...

Clinton Matos @ htxt.co.za writes: With so many projects being made with the Arduino, we’ve seen a fair share of thermometer projects that try to do something different. This version, by educ8s.tv, does so by adopting an older look. Arduino analogue thermometer -...

Brad Linder@ liliputing.com writes: The NanoPi Neo is a tiny computer with a quad-core ARM Cortex-A7 processor, Ethernet and USB ports, and support for a number of accessories. Measuring just 1.6″ x 1.6″ it’s smaller than most Raspberry Pi computers, and with a starting...

by Graham Prophet @ eedesignnewseurope.com Maxim Integrated has posted details of a battery charge monitor IC for which it claims the lowest quiescent current available, at 7µA. The 1-cell Fuel Gauge with Maxim’s ModelGauge m5 EZ algorithm can eliminate battery characterization...

ExaGear is a virtual machine that implements virtual x86 Linux container on ARM and allows you to run Intel x86 applications directly on ARM. With this software by Eltechs you can run Intel x86 application on your ARM-based Mini PC simultaneously with common native applications.  It...

Rex Niven @  edn.com has a design idea on how to drive a character LCD using only one wire. This hardware interface Design Idea reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard...
