Remember the “smart” LED candle from a few months ago? Well, the idea was nice, but the overall execution lacked some oomph. Technologically and aesthetically speaking there was a lot to improve. First off, as an artist, I wanted the container for the candle to look amazing. Or at least better than the old cardboard box I […]

We’ve all got projects kicking around that we haven’t had time to document for our own purposes, let alone expose to the blinding light of the Internet. There are only so many hours in a day, and let’s face it, building the thing is a lot more fun than taking pictures of it. It took

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your

Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the expansion of its line of environmental sensors adding an ultra-low 0.15 to 1.0 PSI pressure sensor. Bourns® Models BPS110/BPS120 pressure sensors are based on state-of-the-art Micro-Electro-Mechanical Systems (MEMS) technology, which provides extremely accurate condition readings in a miniature package size. Designed to deliver superior performance in applications where

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic

Bored of keeping track of countless locks and their keys? How about using your own fingerprint to unlock each and every safe in your house, just like your Smartphone? Sounds cool, right? Let’s make an electronic Fingerprint locker that will keep all your secrets a secret from your enemies. And not only one, but up

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with

Infineon Technologies AG is presenting the fourth generation of its REAL3™ image sensor IRS2771C at Mobile World Congress 2019 in Barcelona, Spain. The 3D Time-of-Flight (ToF) single chip is especially designed to meet the requirements of the mobile consumer device market and, in particular, demand for higher resolutions with small lenses. The wide range of use cases includes secure

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
