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...

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 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...

Jeremy @ thecustomgeek.com updated his RGB LED controller with a bunch of improvements. The new RGBW LED Controller is here! The video above shows some of the things it can do, but here is a list of improvements: IRLB8721PBF MOSFET’s – More power! Double sided and thicker...

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,...

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...

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...

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...
