Arduino is the world’s most popular open-source electronics tool, used every day by millions of people for experimenting and learning electronics. Thanks to the support of the maker community, anyone can share their knowledge and learn from thousands of other projects. You can create anything using basic components like switches and LEDs, or more advance […]

One of the more disappointing news stories of 2019 was the fire at the Notre Dame cathedral. Widely considered a building of great historical importance and architectural merit, it was heavily damaged and will take significant time and resources to repair. Fundamentally though, if you’re reading this, that’s probably someone else’s job. Instead, why not

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots

Car hacking applications have been growing during the last few years, making it faster and cheaper to get into automotive tinkering. A new device was launched recently on kickstarter called M2 by Macchina. M2 is an open-source, versatile development platform which can be wired under the hood for a more permanent installation or plugged into the

We’re not exactly what you’d call naturalists here at Hackaday, so to us, the idea that hot pepper seeds need to germinate in hot conditions sounds suspiciously like a joke. The sort of thing somebody might tell you right before they try to sell you an elevator pass, or cram you into a locker. But

Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using only N bidirectional I/O ports and N resistors (reference 1 and reference 2). Unfortunately, using Charlieplexing allows you to drive only
