Amateur radio operators like to say that working a contact in space can be done with a simple handheld transceiver and a homemade antenna. And while that’s true, it’s true only for low Earth orbit satellites such as the ISS....

Flash storage was a pretty big deal back in the mid ’00s, although the storage sizes that were available at the time seem laughable by today’s standards. For example, having an iPod that didn’t have a spinning, unreliable hard drive...

We’ve been big fans of the Arduboy since [Kevin Bates] showed off the first prototype back in 2014. It’s a fantastic platform for making and playing simple games, but there’s certainly room for improvement. One of the most obvious usability...

Menopause, that fireworks finale of fertility, is like a second puberty that works in reverse. At least, that’s what we hear. Along with mood swings and acne, there are new joys like hot flashes that make you want to jump...

When you’re a kid, one of the surest signs of summer is hearing the happy sound of the ice cream truck crawling through the neighborhood. You don’t worry about how that magical truck is keeping the ice cream cold, only...

Really, how did we get the point in this world where an exercise bike can be bricked? Such was the pickle that [ptx2] was in when their $2,000 bike by Flywheel Home Sports was left without the essential feature of...

We’re proud to announce the Hackaday Remoticon, taking place everywhere November 6th – 8th, 2020. It’s a weekend packed with workshops about hardware creation, held virtually for all to enjoy. But we can’t do it without you. We need you...

Despite being cooked up by Compuserve back in the late 1980s, GIFs have seen a resurgence on the modern internet, mostly because they’re fun. However, all our small embedded systems are getting color screens these days, and they’d love to...

We are saddened to report that William English, co-inventor of the computer mouse, died July 26 in San Rafael, California. He was 91 years old. Every piece of technology starts with a vision, a vague notion of how a thing...

For many of us, this whole pandemic thing has produced some unexpected upsides. One of [George Turvey]’s was finding a nice new scenic route to work that goes by a lake with bike trails. [George] thought it might be nice...

Digital security is always a moving target, with no one device or system every being truly secure. Whether its cryptographic systems being compromised, software being hacked, or baked-in hardware vulnerabilities, it seems there is always a hole to be found....

Imagine that you want to output multiple lines of text in Bash, or any shell script. Maybe it’s for a help string for a particularly convoluted shell script you’re writing. You could have a separate echo command for each line. ...
