ULTRA-LOW QUIESCENT LDO EXTENDS BATTERY LIFE FOR SENSORS AND PORTABLE DESIGNS

Electronics News Updates / By Ibrar Ayyub

With ultra-low quiescent current of 250 nA, the MCP1811 enables battery life which is four-times longer than conventional ultra-low Iq LDO regulators. Compact packages down to 1 x 1 mm also help the MCP1811 to minimise board space. The MCP1811/12 devices are 150 mA (MCP1811) and 300 mA (MCP1812) low dropout (LDO) linear regulators that provide high-current and low-output […]

Charlieplexing Made Easy (and What It Even Means?!)

LED Projects / By Muhammad Bilal

Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout

UPGRADING AN OLD MIG WELDER WIRE FEEDER WITH ARDUINO

Arduino News / By Muhammad Bilal

Older industrial equipment is often a great option if you’re on a budget, and you might even be able to add some premium features yourself. [Brett] from [Theoretically Practical] has done with his old MIG welder, adding premium control features with the help of an Arduino. The main features [Brett] were after is pre-flow, post-flow, and

AT KEYBOARD BECOMES CHILD’S SPEAKING TOY

Arduino News / By Muhammad Bilal

Just as cats find sitting on a keyboard to be irresistible, so do children find pressing their keys. After throwing some ideas around with other parents, [Peter] came up with the idea of transforming an old AT keyboard into a learning toy by making each key press “speak” its corresponding letter. The donor keyboard is a

Control Your Model Train Layout With Your Mobile Phone!

Phone Projects / By Muhammad Bilal

Controlling a model train layout with a wired throttle and turnout controllers might be a good start for beginners but they pose a problem of non-portability. Also, the wireless controllers which come in the market can either control only some locomotives or are a bit too expensive. So, in this instructable, let’s learn how to

NEVER FORGET TO TURN ON THE COOKER HOOD AGAIN

Arduino News / By Muhammad Bilal

The cooker hood is a wonderful invention for removing excess fumes and steam from the kitchen. But like all electrically-powered devices, it only works when it is turned on. This was the problem facing [Peter], whose family are enthusiastic cooks who frequently forget to hit that switch. His solution? An automatic cooker hood switch that comes

COIL ON PLUG IGNITION FOR TINY ENGINES

Arduino News / By Muhammad Bilal

The spark plug was a key invention in the history of the internal combustion engine, allowing combustion to be easily controlled and engines to rev faster than messy earlier designs. Mid-century cars tended to rely on points ignition with a distributor and coil, however more modern designs place a coil on top of each individual
