Lots of op-amp based circuits require dual (symmetrical) power supply. This tiny circuit is a simple solution which provides +/-12V DC 300mA from single 5AV DC   input. The board is based on LM2588-ADJ IC from Texas instruments. Step up from 5V to dual 12V is the best part of the...

With the rapid growth of battery-based devices and tools, efficient energy storage systems are becoming more and more important. Of course there are many researches running around the world working on novel battery technologies. Two new cell technologies are working to deliver energy...

Dilshan Jayakody has published a new build: The current source introduced in this article is capable to handle current up to 6A with maximum input voltage of 50V. This is an operational amplifier based adjustable current source and it uses LM358 in a general voltage follower...

6V Lead acid (SLA) battery charger project is based on BQ24450 IC from Texas instruments. This charger project takes all the guesswork out of charging and maintaining your battery, no matter what season it is. Whether you have a Bike, Robot,  RC Car,  Truck, Boat,  RV, Emergency...

RimstarOrg published an interesting video on his Youtube channel to demonstrate why In north America you can find 3 holes in the electricity socket; which are hot, neutral and ground. The hot wire goes to a breaker-panel and then to electricity grid and finally to a transformer...
