STMicroelectronics and HMicro have announced a single-chip product for disposable, clinical-grade wearable patches and biosensors, to replace wires for vital-sign monitors and electrocardiograms. The IC technology developed by HMicro and ST also targets other high-volume clinical and industrial-IoT applications. By Graham Prophet@ edn.com: Hmicro is a wireless solutions developer working in wireless peripherals and complex […]
FFTs and oscilloscopes: A practical guide
https://www.electronics-lab.com/ffts-oscilloscopes-practical-guide/
Arthur Pini @ edn.com published a guide on how to use FFT found in most modern oscilloscopes. The FFT (Fast Fourier Transform) first appeared when microprocessors entered commercial design in the 1970s. Today almost every oscilloscope from high-priced laboratory models to the lowest-priced hobby models offer FFT analysis. The FFT is a powerful tool, but […]

Dejan Nedelkovski build an Arduino-powered MP3 Music Player plus Alarm Clock. The player has a 3.2″ TFT display and the home screen displays time, date and temperature along with touch control buttons. In this project I will show you how you can make an Arduino Touch Screen MP3 Music Player and Alarm Clock. You can watch the following video or […]
Lightweight Body Heat – Electricity Converter
https://www.electronics-lab.com/lightweight-body-heat-electricity-converter/
Powering wearable technologies using thermoelectric generators (TEGs) is becoming more efficient. An undergraduate student in North Carolina University, Haywood Hunter, is producing a lightweight and an efficient wearable thermoelectric generator. It generates electricity by making use of the temperature differential between the body and the ambient air.This converter produces 20 times more electricity than other […]
LTM2889 – Isolated CAN FD µModule Transceiver and Power
https://www.electronics-lab.com/ltm2889-isolated-can-fd-%c2%b5module-transceiver-power/
The LTM2889 is a fully ISO 11898-2 compliant CAN (controller area network) μModule transceiver and isolator that guards against large ground-to-ground differentials and common mode transients in 3.3V or 5V applications. In practical CAN systems, ground potentials vary widely from node to node, often exceeding the tolerable range, which can result in an interruption of […]

Tibbo Project System-based Aircon Controller Application
https://www.electronics-lab.com/tibbo-project-system-based-aircon-controller-application/
The app allows you to manage traditional air conditioners that are controlled through infrared remotes. Designed for the office environment, the app relies on the ambient brightness (measured by Tibbit #28) to determine whether the aircon should be running or not. In the office setting, no lights = no people = no need for the […]
8 Channel RS485 Relay Board
https://www.electronics-lab.com/8-channel-rs485-relay-board/
This project helps you control 8 relays using RS485 link with the help of a PC. This kit can effectively convert a standard PC to a powerful PLC ( programmable logic controller ). At the PC end , you will need to use our RS232 to RS485 Interface – C020 or any other suitable […]
Dual input, 2.5A step-down DC/DC achieves 95% efficiency
https://www.electronics-lab.com/dual-input-2-5a-step-dcdc-achieves-95-efficiency/
by Graham Prophet @ edn.com: LTC3126 is a 2.5A, 2.4V to 42V input, synchronous step-down switching regulator with integrated dual input PowerPath control. Its power stage topology enables operation from either of two independent power sources, with seamless, internally controlled transitions between inputs to ensure a stable output voltage during hot-plug and power source disconnect […]
Lithium-ion battery fires: 7 solutions for improved safety
https://www.electronics-lab.com/lithium-ion-battery-fires-7-solutions-improved-safety/
Steve Taranovich discuss about various ways to enhance Li-Ion batteries safety. Typically, Lithium-ion batteries are safe and reliable. Just think about the $28B market they had in 2013 with a relatively small amount of fires and explosions. But every fire and explosion incident has the potential to cause a loss of life or serious personal […]
