MechBass Grooves on Some Muse

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.

3D-Printed Gun Fires off Six Shots Before Going Kaput

Everyone’s going crazy over 3D printing these days, and understandably so. The concept seems like it’s something from the pages of a sci-fi book, and now researchers have managed to turn it into a reality.

3D Printed GunThe coolest thing about 3D printing is that the sky is really the limit. You can now ‘manufacture’ toys, gadgets, and even weapons from 3D scans, patterns, and of course, a good 3D printer. It’s impressive stuff, but when it comes to the last bit, it’s also pretty scary.

A couple of amateur gunsmiths came together and had a some gun parts printed so that they could put together a fully-functional AR-15 semi-automatic rifle. They tested out the 3D-printed lower receiver recently and results were pretty good at first – that is, until they got to their sixth shot.

Note that the receiver was the only 3D-printed part used in the test; all others used were actual gun parts.

What do you think?

Tweet-Speaking Radio Brings the Latest News and Random Rants

Twitter is probably the most up-to-date source of both the most useless as well as the important issues of the day; it’s like a thousand free radio stations where some broadcast nothing but ads while the rest have schizophrenic DJs and reporters. So… it’s not like a radio station at all. But I still find this tweet-speaking radio to be an awesome mod.

The not-radio was made by Sean Hathaway, who calls his device “Volume and Noise.” It has a wooden case from an antique radio but its innards and display have been upgraded with equipment like a newer amplifier, an Arduino microcontroller and a meter that shows the number of tweets per minute.

It filters tweets based on user-defined search terms and then converts them to speech using synthetic voices. In the video below Volume and Noise is tuned in to political search terms. I like the addition of static and tuning sound effects.

I wonder if it would be possible to order it to make a voice command that tells the radio to save or mail a link to the tweet it just read. That way it would be even more useful.

Dad Builds Quadcopter to Walk His Son to the Bus Stop

Some of you will think this guy is the best dad ever, while others will think he is lazy. Personally I think he’s pretty awesome. Paul Wallich has entrusted a quadcopter to walk his son to the bus stop.
Guy Builds Quadcopter to Walk His Kid to the Bus Stop
The quadcopter was keyed in to track a GPS beacon in his son’s backpack. This is high-tech parenting at its best. This flying drone can follow his child from a set distance and make sure the kid stays safe and out of trouble, while pop watches the remote video camera from the comfort of his computer screen.

Getting this device to follow his kid was the tricky part. An RFID solution would have required a bulkier antenna than the craft could really carry. So he used a navigation program that keeps the copter a set distance away from the GPS beacon it is following. This kid is hopefully pretty popular right now thanks to his dad’s inventiveness.

Now he just needs to rig it to fire projectiles at any bullies his son encounters on the way to school.

Raspberry Pi Micro Arcade Machine: A Sweet Slice of Classic Gaming

A couple of weeks ago we saw a Kickstarter fundraiser for a desktop arcade machine based on the Raspberry Pi. It turns out that hacker and tinkerer Jeroen Domburg has already made a tinier, yet also functional machine based on the same computer.

Wow. So many wonderful features in such a tiny package. I think it’s as small, if not smaller, than the Space Invader cabinet we saw a while back, but this one runs MAME so it can run tons of classic (and not-so-classic) games. It has a transparent cabinet made from laser-cut acrylic, a 2.4″ LCD screen and an itty bitty OLED display up top that displays the logo of the game being played (if available). It runs on a Li-ion battery that can be recharged via USB.

This project is definitely not for beginners, but if you have the skills Domburg has posted a thorough step-by-step on his website.

Winulator Runs Windows 95 & 98 Games on Android

Technology is quickly catching up to satisfy our nostalgia. We have modders making amalgams of old consoles, calculators that can run Pokémon and now this, a prime contender for Technabob’s non-existent app of the year awards – an app that lets Android devices run Windows 95 & 98 games.

winulator windows 95 98 wrapper for android by dan aloni

The app is called Winulator, and it was made by a genius called Dan Aloni. Winulator implements “DirectX and Win32 calls”, i.e. it lets games run on the Android OS despite them being developed for the older Windows operating systems. But most of these games were made not just with a certain OS but also with certain hardware in mind, particularly Intel Pentium processors, and not the ARM processors found in today’s Android devices. Fortunately Winulator takes care of that as well. It can either compile as needed or “compile the entire binary before it runs.” In layman’s terms? StarCraft on your smartphone. Actually that’s a stupid setup but still. It’s possible.

Winulator isn’t finished yet, but Aloni is planning on releasing it via the Google Play market when it’s done. Meanwhile dig up your old installers and get to ripping.

LazerWood Lace iPhone Cover Shows of Your iPhone’s Sexy Underthings

I’ve never really tried to customize the back of my iPhone, since I use cases, but if you use a pouch or have your iPhone naked, then this back cover has got some interesting design elements that might catch your eye by dressing your iPhone in a little black lacy thing.

lace iphone cover lazerwood

The Lace iPhone cover was designed by textile artist Anne Marie Jackson, and it’s a thin, but durable wood back cover for the iPhone 4, 4S, and 5. The case features a laser-embossed lace texture that’s been finished with in black to make it stand out from the woodgrain underneath. You just peel and stick it on the back. It’s supposed to be easy to remove without leaving any residue or damage. It’s also designed to work with the Apple bumper. I guess that together these act like a full-on case.

The Lace back cover is available from LazerWood for $30(USD), including a free screen protector.

Ben Heck Analog WASD Keyboard Mod: Because You Can’t Type With a Joystick

Modder Ben Heck has removed one of the few remaining advantages of videogame consoles over the PC master race: the analog stick. Heck sacrificed an Xbox 360 controller to make the W, A, S and D keys on his keyboard behave like the left stick on the controller, i.e. the harder he presses the keys, the faster his character moves in game. Or whatever “-er” is supposed to happen.

ben heck analog keyboard wasd mod

Aside from an Xbox 360 controller, Ben Heck also used magnets, Hall effect sensors and a microcontroller to complete the mod. He ends up with WASD keys that are much more useful in PC games that support gamepads. You can skip to about 10:00 in the video to see Heck test his modded keyboard:

If you already had your soldering spellbook and modding whatzits close at hand, head to Ben Heck’s website to grab the files and code you’ll need for the mod.


LEGO Brick Keyrings: Simple Genius

If you’re always losing track of your keys, it’s nice to have a place to hang them up when you come and go from the house. I’ve got a couple of little hooks on the wall, but I’m digging this idea much more.

lego keychain 1

Designer Felix Grauer came up with the idea of a simple keyring with a LEGO-compatible brick on it. To hang your keys up, simply snap the brick onto a wall-mounted LEGO panel, and you’re set. Make sure to leave them hanging over by one position to make them easy to remove. Not only can you use the blocks to color-code individual keyrings, but you can snap them together to combine rings.

I love simple, smart ideas like this that just plain work. Now all I need is some LEGO bricks with holes drilled in the side of them, and I’ll be all set. I suppose for now, I’ll just have to settle for some of these.
