DIY Voltmeter using a simple voltage sensor and Arduino Uno and a Nokia 5110 LCD
In this video we are going to learn how to build our own voltmeter using a very inexpensive sensor. The voltage we measure is then displayed in a Nokia 5110 LCD display. This project is very easy to build and great learning experience. With this project we can measure the voltage of...

LED current regulator has low dropout
Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the...

Battery-pack fuel gauge with SHA-256 authentication prevents pack cloning
Implementing pack-side battery gauges in portable devices is easier and more secure, Maxim asserts, with its ModelGauge m5 portfolio of MAX17201/MAX17205 and MAX17211/MAX17215. Fuel gauging can be difficult because battery voltage varies with temperature and load, while...

How to Improve Buck Converter Light Load Efficiency with an LDO
By Michael Hartshorne @ digikey.com: Designing a DC/DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in...
