Star Wars Droid Translating Helmets

February 20, 2016 by 15 Comments

Now how’s this for an expo costume? [AEInnovations] put together a set of Droid helmets that talk to each other in droid speak!

Before you get too excited, we have to let you know, they aren’t actually translating anything. One, there’s no such thing as a complete droid speak language from Star Wars, and two, it’d be ridiculous. No, what he’s created is a bit simpler, but nonetheless awesome and very clever.

The helmets have walkie talkies built in, so two people wearing the helmets can simply talk to each other, in plain old English — well, or maybe Klingon. But when you speak, a sensor in the helmet notices you speaking, and starts broadcasting a randomized droid speech for everyone else to hear.

Imperial Shuttle Drone Is Sure To Scare The Cat

February 20, 2016 by 16 Comments

[Adam Woodworth] tries to build some kind of RC plane every month. He’s been at it for almost a decade, and he’s getting pretty damn good at it. By day, he’s a Hardware Engineer at Google, though he went to MIT for Aerospace Engineering. Coincidence? We think not.

His latest project is an Imperial Shuttle drone, or to be specific, a Lambda class imperial shuttle — the infamous Shuttle Tydirium. You have to watch this thing unfold.

Using paper model plans, [Adam] printed out the shuttle on a combination of 3mm and 6mm thick foam board (Depron), and then assembled it. This kept the model light enough that the set of quad rotors would have more than enough power to fly it around.

5D Glass Disc Can Store 360TB!

February 18, 2016 by 154 Comments

There’s a small subset of hackers out there concerned with the end of the world. What if our entire existence vanished? How would an alien race learn not to do what we did, what resulted in our demise? We’ve all heard of laser etching metal disks with the Bible, accounts of history, and even just names — pretty sure we’ve sent quite a few into space. But researchers at the University of Southampton’s Optical Research Center have come up with an even superior storage method. They call it the 5D Disc.

According to the researchers, each disc could hold a theoretical 360TB. They can withstand temperatures of up to 1000C, and it’s believe that they could last up to 13.8 billion years at room temperature without degrading — if that’s true, our sun would be long dead before the disc degraded!

The Internet Of Cats

February 15, 2016 by 70 Comments

With the miniaturization of technology, we’re now able to do some pretty crazy things with computers the size of credit cards. [Dennis] has been working on a rather unique project — he calls it the Cat Exploit — we call it the Internet of Cats.

By making pet-wearable tech (is that a new term?), it’s possible to create a mini war-driving server that stray cats (or other small animals) could wear. As they roam the streets, their feline-augmentation searches and taps into open or badly secured WiFi networks, repeating and spreading the signal to other Server Entities (other network-enabled cats), opening up the networks for all to use.

Gatling Gun Shoots Arrows Out Of Coke Bottles

February 12, 2016 by 20 Comments

[JoergSprave] has done it again. His latest, most ridiculous weapon? A Gatling gun that fires crossbow bolts, using compressed air inside coke bottles — and an electric screwdriver.

For those of you not aware, [Joerg] is our favorite eccentric German maker, a purveyor of slingshots and all things ridiculous and weaponised. He runs the SlingShot Channel on YouTube, and has graced us with things like a slingshot cannon (firing 220lb balls!), a machete slingshot for the upcoming zombie apocalypse, and more.

Each coke bottle has a quick release pneumatic air valve, with a wooden lever attached to it to make opening the valve easier and quicker. The coke bottles are pressurized separately using an air compressor, but can also be filled using a bicycle pump — he got his hands on a pump capable of putting out 300 PSI! Word of safety though — you really don’t want to use coke bottles as pressure vessels — but [Joerge] is crazy so we’ll let it slide.

Balancing D-Pad Gets You In The Game

February 6, 2016 by 14 Comments

Inspired by TRON, [lasttraveler] decided to try his hand at building a Balance Board — basically a giant joystick pad you can stand on to control.

Constructed of solid wood, the switches are actually very simple — he’s just using tin foil to make the contacts. By opening up the sacrificial keyboard, he’s taken the up/down/left/right keys and wired the contacts directly to the four tin foil pads. A recess in the bottom of the board allows the rest of the keyboard to remain intact — in case he ever wants to take it apart again. Or add new buttons!

Wooden crossbeams in the shape of an X allow the board to balance in the middle without touching any of the contacts — but as soon as you lean the connections are made and you’re off to the races!

Now strap on a VR headset and play some TRON! Though if you want even more accurate control you might want to pick up a cheap Wii balance board instead.

Tinijet — Affordable Waterjet Cutting At Home

February 4, 2016 by 63 Comments

While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.

In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.

We first covered this project a few years ago when it was just a university research project called Hydro — it’s since evolved immensely, and will be available for sale very soon.
