REPURPOSED PLASTIC PROTECTS PCBS

An errant wire snipping across the wrong electrical pins spells the release of your magic smoke. Even if you are lucky, stray parts are the root of boundless malfunctions from disruptive to deadly. [TheRainHarvester] shares his trick for covering an Arduino Nano with some scrap plastic most of us have sitting in the recycling bin. The video is also after the break. He calls this potting, but we would argue ...

Tyre pressure monitoring system using Bluetooth Low Energy

Author: Maurizio Di Paolo Emilio A tyre pressure monitoring system (TPMS) aims to monitor air pressure on various automotive systems. The most common TPMS sensors mainly use sub-GHz radio standards to transfer information to the vehicle’s computer. There are two different types: direct (dTPMS) and indirect (iTPMS). The use of bluetooth low energy (BLE) connectivity makes it possible offering a high performa ...

Nanoscale refrigerator helps quantum computers keep their cool

The next big breakthrough for electronics is likely to be quantum computers, which will increase digitized memory capacity exponentially and allow scientists to start tackling problems that our classical computers have no hope of handling right now. Companies like IBM are starting to make some headway, but there are still plenty of hurdles to jump before practical quantum computers become a reality. A team ...

SIMPLE ARDUINO UNIVERSAL REMOTE CONTROL

The infrared remote control might not hold the seat of honor in the average home theater setup that it once enjoyed, but it’s not quite out to pasture yet. After all, what are you going to use to stop Netflix once the Chromecast invariably disconnects from your phone? As long as there are devices out there that will respond to commands blasted their way via an IR LED, hackers will be looking to get in on th ...

YET ANOTHER ROBOTIC RUBIK’S SOLVER

The Rubik’s Cube was a smash hit when it came out in 1974, and continues to maintain a following to this day. It can be difficult to solve, but many take up the challenge. The Arduino Rubik’s Solver is a robot that uses electronics and maths to get the job done. The system consists of computer-based software and a hardware system working in concert to solve the cube. Webcam images are processed on a compute ...

SO, YOU WANT TO BUY A MAINFRAME

The computers we are used to working with are more likely to be at the smaller end of the computational spectrum. Sometimes they are very small indeed, such as tiny microcontrollers with only a few GPIOs. Others are single board machines such as a Raspberry Pi or an Arduino, and often a desktop or laptop PC. Of course, while these can be very capable machines, they don’t cut the mustard in the upper echelon ...

Solar Power Module v2

Ideation I build connected sensors, which are often deployed in local parks where there is no access to utility power. Over the past couple years, I have been refining and testing my solar power modules, and have arrived at this compact integrated design. I have a number of these deployed and they have been in continuous service for up to two years. I wanted to share this design in case it might be helpful ...
