Lithium-ion batteries are very popular as they're lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately,...

4 Channel Relay Board is a simple and convenient way to interface 4 relays for switching application in your project. Very compact design that can fit in small area, mainly this board is made for low voltage applications. Features Input supply 12 VDC @ 170 mA Output four...

Single Channel Large current relay board with dual DC-DC converter board is mainly designed for Hobby CNC, Routers, and Plasma cutters. Hobby CNC controller requires multiple DC outputs to drive various things.  This board provides 5V DC and 12V DC 1Amp each. The dual supply helps...

4-Channel Relay Board is a simple and convenient way to interface 4 relays for switching application in your project. The project has large Relay which can switch current up to 20Amps. Specifications Input supply 12 VDC @ 360 mA Output four SPDT Relay Relay specification...

The first step toward finding ways to reduce home electricity usage begins with installing an energy monitoring system. These days you can find an electric meter in every residence, but it is likely that you would find it installed in a location that is more convenient to access for a...

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...

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...

AEM10940 is a power management IC designed by e-peas to store power from photovoltaics (PVs) cells and thermoelectric generator (TEGs) into rechargeable power sources, such as Li-Ion batteries and thin film batteries. At the same time, it supplies the system with two different regulated...
