Coffee Table Railroad Flips to Hide the Fun

The livingroom coffee table has long been a favorite realm of the model railroad. But what to do when you actually want to have coffee? [Peter Waldraff] has come up with a most eloquent answer to the problem by designing a coffee table model railroad capable of turning the world upside down. This isn’t [Peter’s] first rodeo. In his demo video below...

Antique Map of Paris With Modern Tech

There’s plenty to love about antiques, from cars, furniture, to art. While it might be a little bit of survivorship bias, it’s easy to appreciate these older things for superior quality materials, craftsmanship, or even simplicity. They are missing out on all of our modern technology, though, so performing “restomods” on classics is a popular activity...

Orphaned IoT Sleep Tracker Resurrected as an Air Quality Monitor

If you have a Hello Sense sleep tracking device lying around somewhere in your drawer of discards, it can be brought back to life in a new avatar. Just follow [Alexander Gee]’s instructions to resurrect the Hello Sense as an IoT air quality data-logger. In 2014, startup “Hello” introduced the Sense, an IoT sleep tracking device with a host of embedded...

The Last Days of the Wild West

We loved it a few weeks ago when an international team of hackers managed to record and decode telemetry and images from SpaceX launches. And now it looks like SpaceX has started encrypting it all in response. Booo! Decoding satellite and other space ship transmissions has been a great hacker pastime. Most recently, we’ve seen a group working on listening...

Newest PlayStation Exploit Skips the Disc

Last month we brought you word of tonyhax, a clever exploit for the original Sony PlayStation that leveraged a buffer overflow in several of the games from the Tony Hawk Pro Skater series to load arbitrary code from a specially prepared memory card. But now [Bradlin] has taken that idea a step further and developed a software exploit for Sony’s iconic...

Dynamic Build Platforms for 3D Printers Remove Supports and Save Material

We’re all too familiar with the 3D printing post-processing step of removing supports, and lamenting the waste of plastic on yet another dwindling reel of filament. When the material is expensive NinjaFlex or exotic bio-printers, printing support is downright painful. A group at USC has come up with a novel way of significantly reducing the amount of...

NASA’s Lucy Stretches Its Wings Ahead of Trojan Trek

The good news about using solar power to explore space is there are no clouds to block your sunlight. Some dust and debris, yes, but nowhere near what we have to deal with on planets. The bad news is, as you wander further and further out in the solar system, your panels capture less and less of the sunlight you need for power. NASA’s Lucy spacecraft...

Kerbal Space Program Goes to the Movies in Stowaway

Fans of the lusciously voiced space aficionado [Scott Manley] will know he often uses Kerbal Space Program (KSP) in his videos to knock together simple demonstrations of blindingly complex topics such as orbital mechanics. But as revealed in one of his recent videos, YouTube isn’t the only place where his KSP craft can be found these days. It turns...

Engineering the Less Boring Way

We have to admire a YouTube channel with the name [Less Boring Lectures]. After all, he isn’t promising they won’t be boring, just less boring. Actually though, we found quite a few of the videos pretty interesting and not boring at all. The channel features videos about mechanical engineering and related subjects like statics and math. While your typical...

Laser-Cut Solder Masks from Business Cards

There are plenty of ways to make printed circuit boards at home but for some features it’s still best to go to a board shop. Those features continue to decrease in number, but not a lot of people can build things such as a four-layer board at home. Adding a solder mask might be one of those features for some, but if you happen to have a laser cutter...
