There is a device under test out there that promises to take humans to another star in a single lifetime. It means vacations on the moon, retiring at Saturn, and hovercars. If it turns out to be real, it’s the greatest invention of the 21st century. If not, it will be relegated to the history of terrible science right underneath the cold fusion fiasco. It is the EM drive, the electromagnetic drive, a reactionless thruster that operates only on RF energy. It supposedly violates the laws of conservation of momentum, but multiple independent lab tests have shown that it produces thrust. What’s the real story? That’s a little more complicated.
The EM Drive is a device that turns RF energy — radio waves — directly into thrust. This has obvious applications for spacecraft, enabling vacations on Mars, manned explorations of Saturn, and serious consideration of human colonization of other solar systems. The EM drive, if proven successful, would be one of the greatest inventions of all time. Despite the amazing amount of innovation the EM drive would enable, it’s actually a fairly simple device, and something that can be built out of a few copper sheets.

The massive engineering-defying Helicarrier from the Avengers is a brilliant work of CGI. Too bad it’d never actually fly… Like… Never.
Luckily, that didn’t stop our favorite RC hackers over at FliteTest from making a scale model of it — that actually works! If you’re not familiar, the Helicarrier is a fictional ship, the pride of S.H.I.E.L.D’s air force, or is it their navy.
It’s a massive aircraft carrier with four huge repulsor engines built into it, borrowing tech from Stark Industries. The shear size of it is what makes it completely ridiculous, but at the same time, it’s also unbelievably awesome.
Unfortunately, repulsor technology doesn’t seem to exist yet, so the FliteTest crew had to settle with a set of 8 brushless outrunner motors, with two per “engine”. The whole thing is almost 6′ long.
It doesn’t handle that well (not surprising!) but they were able to launch another RC plane off of it, mid-flight! Landing however… well you’ll have to watch the video. Continue reading “Lego Avengers Assemble to the Helicarrier!”
[Dustin Evans] is a big fan of the recent Avengers movies — heck, we are too! So he decided to make this awesome Tesseract Case prop replica!
Tesser-what? A tesseract, or cubic prism is a geometric shape that is technically a four-dimensional hypercube — in the Avenger’s movie, it is an incredibly powerful and unstable alien energy source.
To make the replica, [Dustin] picked up a cheap aluminum tool case from the hardware store, took some measurements and began designing the inside of it using SketchUp. He’s crammed in an Arduino with a spectrum shield, a BlueSmirf Bluetooth modem, a Raspberry Pi, a 7″ LCD, speakers and an amp, a WiFi card for the Pi, and a few strips of Neopixels. It is running Raspbian with a stand-alone version of XBMC, which means using AllCast he can wirelessly control the box from a phone or tablet — now all he’s missing is a mini-generator that can put out a few million watts!
