[Dan Ros] and the mbed team sent in their hack of a twitter talking Big Mouth Billy Bass. Originally the hack simply had an mbed micrcontroller and an SD card with some wav files allowing Billy to say classic quotes. Wanting to go further however, they used the mbed’s HTTPClient library to grab Twitter updates, and then have Billy say them out loud! Check out some other cool projects the mbed team has in the cookbook.

But wait, whats an mbed? We didn’t have a clue either!

Some researched reveals it is a powerful new microcontroller and prototyping board. With some features such as direct ethernet and USB connections right on the chip, as well as PWM, serial, analog, and more. What really stoked us is how it acts much like a USB thumb drive. Drag and drop your binary files, and it’s programmed! The only downside, at $100 it can be a bit more of an investment compared to an Arduino PIC. Could this be the next big prototyping tool that beats all others? Lets hear it in the comments!

[Update:  The mbed can be had for a  limited time pre-order price of $60  not $100 – Thanks Dan and the mbed team!]

Arduino-human Synthesizer

(Thanks to [Aaron] for the tip) As a promo for [Calvin Harris], some of the creative minds at Sony Music have put together an Arduino-based sythesizer composed of 15 bikini clad babes. By analyzing which circuits are closed, the Arduino Mega is able to tell a sequencer which sample to play. The only innovation happens to be that the circuits are painted onto the aforementioned girls with a conductive body paint known as Bare.

Developed by students at the Royal College of Art, the paint is not available for purchase, but they are willing to mix a batch up for art installations or performances. Technical stats (such as resistance) have not been released, but for a washable paint it seems to be performing quite well.

How was the whole project set up? The video below reveals all:

Berlin Hack Day

This past weekend, Berlin played host to Music Hack Day – an event where attendants built and tested hacks, contraptions, and software all dealing with sound, music, or the distribution thereof. Some of the hacks are simply mind blowing to see built in only a day or two. Like the location based CitySounds.fm or Tracks on a Map – mapping out where your music is from. Or the music based games and composition tools, iLoveAcid squencer and MaschineFighter – adding some crazy fun to MIDI.

Oh, we almost forgot, we can’t go an entire post without mentioning something Arduino; named Xylobot – a set of servos powered by Arduino, tapping out rhythm on a xylophone (video above). Another Hack Day is planned so keep an eye out.

MP3 Hand Grenade

hand_grenade_mp3

One man’s useless machine is another man’s treasure… or something. [Matt] shared a link to his MP3 gr3nade in the comments of our useless machines post. The project took a decomissioned hand grenade and shoehorned an MP3 player into it. His decision to locate the headphone jack where the safety pin goes is a nice touch.

This reminds us of the boss from a previous job who had a chrome plated hand grenade on his desk.  Now that was a useless object (and a useless boss). This project actually does something, but are you really going to ride around on the subway rockin’ out to the Bee Gees while holding a hand grenade?

Head Bangers Beware: Motion Sensing Headphones

tiltphones

The iPhone doesn’t have the market cornered on the use of accelerometers. The tiltphone project incorporates a three axis accelerometer into a set of headphones transforming them into a remote control for an iPod. A PIC16F690 reads in data from the analog sensor, translates specific movements into commands, and like the Arduino iPod Remote from last week, relays them to an iPod via the Apple Accessory Protocol. A quick nod left or right skips tracks, holding a sideways nod controls the volume, and setting the headphones down pauses.

This project is a bit older but we’re glad [anon] tipped us off as we hadn’t seen it before. There doesn’t seem to be any code or schematics available but because the Apple Accessory Protocol is known, it’s only a matter of working out how to interpret the sensor data. There is video after the break and if you pull off this hack yourself be sure to send in details for a followup.

Classy Hard Drive Speaker Set

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front. The project is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is an iPod dock!

Monome Mainstream: Performance On Letterman

September 8, 2009 by 20 Comments

monome_played_on_letterman

The monome was spotted being used in a performance by Imogen Heap on Late Night with David Letterman. Imogen uses the monome 256 model connected to a laptop sitting on the piano. In her performance she uses a combination of live samples and pre-recorded loops proving how great this product is in the hands of an accomplished artist.

Although not identified by name (or function), Letterman does notice the monome at the end of the performance. To see this kind of exposure for an innovative open source product is wonderful. Check out the Letterman clip as well as a monome bonus after the break. Continue reading “Monome Mainstream: Performance On Letterman” →
