The big problem with Low Earth Orbit is, oddly enough, air resistance. Sure, there’s not enough air to breathe in space, but there is enough to create drag when you’re whipping around the planet at 28,000 km/h (17,000 mph) or more. Over time, that adds up to a decaying orbit. [Eager Space] recently did a […]
While we often get a detailed backstory of the projects we cover here at Hackaday, sometimes the genesis of a build is a bit of a mystery. Take [maurycyz]’s radiation survey meter modifications, for instance; we’re not sure why such a thing is needed, but we’re pretty glad we stumbled across it. To be fair, […]
A book of mechanical actions is a wondrous thing — mechanically inclined children have lost collective decades pouring over them over the generations. What could possibly be better? Why, if the mechanisms in the book were present, and moved! That’s exactly what [AxelMadeIt] produced for a recent video. Being just four pages, you might argue […]
This week Jonathan and Rob chat with Paulus Schoutsen about Home Assistant, ESPHome, and Music Assistant, all under the umbrella of the Open Home Foundation. Watch to see Paulus convince Rob and Jonathan that they need to step up their home automation games! https://www.home-assistant.io/ https://esphome.io/ https://www.music-assistant.io/ https://www.openhomefoundation.org/ Did you know you can watch the live […]
Of the many great technological leaps made in the middle of the 20th century, one of the ones with perhaps the greatest impact on our modern life takes a back seat behind the more glamorous worlds of electronics, aeronautics, or computing. But the ancestor of the modern tractor has arguably had more of an impact […]
Taking a look inside the human body has never been easier — just swallow a camera in the shape of a pill. However, what is not quite as easy is retrieving a piece of whatever you’re viewing. This is exactly what researchers from HIT Shenzhen have attempted to solve with their magnetic capsule bot. When […]
The advent of rooftop solar power generation was a huge step forward for renewable energy. No longer was generating electricity the sole preserve of governments and major commercial providers; now just about any homeowner could start putting juice into the grid for a few thousand dollars. Since then, we’ve seen the rise of the home […]
If we’re talking about oxidized iron… probably nobody. If we’re talking about Rust the programming language, well, that might be a different story. Google agrees, and is working on bringing the language into Android. That’s not enough for [Paul Sanja], who has the first Redox OS smartphone. It’s alive! Redox OS is a Unix-like operating […]
For the past two-and-half years Canadian consumer testing outfit RTINGS has been running an accelerated aging experiment across a large number of TVs available to a North-American audience. In their most recent update, we not only find out about the latest casualties, but also the impending end of the experiment after 18,000 hours — as […]
Once upon a time, many radios and TVs only came with a single (mono) speaker. Then someone decided all audio hardware should have as many speakers as we have ears. That was until [Olivia] came along, and whipped up a dodecahedron speaker as an educational piece for workshops. Really, it shows us that twelve speakers […]
