LT8315 – 560VIN Micropower No-Opto Isolated Flyback Converter
https://www.electronics-lab.com/lt8315-560vin-micropower-no-opto-isolated-flyback-converter/
The LT8315 is a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation. The LT8315 operates over an 18V to 560V input voltage range, has a […]
Educational Biomed Shield for Arduino 101
https://www.electronics-lab.com/educational-biomed-shield-arduino-101/
Orlando Hoilett has built his new biomedical Arduino 101 shield: Biomed Shield, in order to allow students, educators, and hobbyists to learn about bio-medicine by monitoring heart rate, temperature, and other physiological metrics. To build this shield he used the following components: AD5933 MLX90614 Microchip Rail-to-Rail Input/Output Dual Op-Amp MAX30101: a specialized integrated circuit that is able […]
Making the Electronics for CDM324 – 24GHz Doppler Motion Sensor
https://www.electronics-lab.com/making-electronics-cdm324-24ghz-doppler-motion-sensor/
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 HB100 is using a 10.525GHz frequency, […]

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 potentiometers: 10 or 12-bit DAC from the […]

NanoPi NEO kit lets you build your own network-attached storage system for about $30
https://www.electronics-lab.com/nanopi-neo-kit-lets-build-network-attached-storage-system-30/
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 price of $7 it’s also an awfully affordable computer capable of […]
MAX17055 – a 7μA operating current fuel gauge

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 is like QEMU but 5 times faster! You can even run Windows […]
One wire controls LCD module
https://www.electronics-lab.com/one-wire-controls-lcd-module/
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 interface, or even an opto-isolator. One wire […]
