Hasta La Gadget!

That guard you just stealth-killed in Dishonored never heard you coming. But everyone else did. Which is why you might want to consider a noise-dampened mechanical keyboard of some sort. There are a few of ’em out there, not least the Matias Quiet Pro we reviewed last year, and now Razer has a keypad option solely for gamers: a new Stealth Edition of the original Orbweaver that came out in January. The price is unchanged at $130, as are the main specs and adjustable design, but Razer promises “silent tactile feedback” that provides an “entirely new feel,” alongside a slightly reduced actuation force of 45g (instead of 50g). Perhaps your long-suffering colleagues will throw in a decent headset to go with it.

Over the years, there have been numerous attempts to make motorized shop tools out of LEGO. Now, the guy behind the LEGO 3D milling machine is back with a new creation – a lathe that can create custom forms by tracing a simple outline.

Arthur Sacek actually made his first LEGO lathe back in 2005, and now he’s remade the machine and shared it with the world to enjoy. The machine uses LEGO RCX components (now known as Mindstorms), and can cut cylindrical forms from floral foam using a spinning bit. To make a shape, Arthur loads up a block of foam, then draws a curve profile on a white piece of paper. The system then automatically traces the line and carves the shape from the rapidly-spinning foam. It’s quite impressive in action:

The LEGO motors probably aren’t powerful enough to turn wood, though I wonder if it could handle something soft like balsa.

I’ve heard of corrugated cardboard being used to house computers, but this project takes cardboard computing to a whole new level. Niklas Roy used rubber bands, rope and cardboard to create a functional, mechanical computer and plotter.

Niklas Roy taught an electronic media class at Germany’s School of Art and Design Offenbach. The goal was to create a series of mechanical cardboard computers from scratch. Shown here is one of those machines. This fully operational NAND gate and plotter were designed out of Finnish cardboard. The complete system was assembled using super glue, adhesive tape and tie wraps and rubber bands.

The plotter has axles and slide rails made out of welding rods. There are two rotary dials and a switch, which move in a plane, controlling the movement of a pen as it “vectors” to produce low resolution graphics on a sheet of paper.

Be sure to check out Niklas’ blog for more of the contraptions built by the class. This is definitely an awesome project, and it makes you wonder what you could do at home, given enough time and ingenuity.

OK, so basically, self-replicating robots are a no-no when it comes to robotics, because you don’t want them to start taking over the planet and exterminating humans. I for one, don’t welcome our robotic overlords.  iRobot and Raytheon recently filed a patent which could be the source of something scarily robotic. Thankfully, this isn’t exactly what they’re after, but it wouldn’t take much to make so-called “von Neumann machines” a reality with this device in hand.

The patent for the Robot Fabricator is for a machine that would allow products of all sorts to be autonomously constructed. Its capabilites would range from the creation of seed components to the assembly of finished products without any direct human involvement.

While we’re still quite far from the scenario of what happened in the Dune novels by Frank Herbert, in which machines enslaved humanity, things could still go very wrong very quickly. If such a device got into the wrong hands grippers, robots could be popping up everywhere. Scary, huh?

Despite the increasing number of robotic musical acts, I’m still always tickled by the idea of a band that does away with the human element, and puts robots in their rightful place – to entertain their masters. The latest robot musician – a mechanical bass-playing ‘bot.

Engineering student James McVay created the MechBass as his honors project at New Zealand’s Victoria University. The robot uses a set of four individual bass strings along with a motorized pick wheel to jam out its tunes.

A linear-motion system moves a pitch-shifter that frets the strings by applying pressure to them, and a servo-controlled damper mechanism can stop the strings from vibrating quickly. Optical pickups then capture the sounds, and send them to an audio circuit and amplifier.

The whole system is controlled using MIDI signals and an audio programming language called ChucK, so it can play pretty much any tune that can be played on a bass. A custom controller board using an ATMega328 processor acts as the bridge between the software and the hardware.

But don’t just take my word for how cool this thing is. Here’s a video clip of MechBass pounding out the intense bassline of Muse’s Hysteria.

While I don’t know if it’ll be replacing Flea in the Red Hot Chili Peppers anytime soon, I’m still totally impressed by MechBass’ musical talents.
