The MicroGranny, a DIY Granular Sampler

The user [selcukartut] sent us a project full integrated with Arduino boards. Filika (Istanbul) designed and produced an Interactive Percussion Playing Car for Volkswagen’s breathtaking pickup Amarok. Several sensors were implemented on the board, so that the participants were able to trigger percussion sounds via tapping their hands on the car.
Technically speaking, there were two types of sensors to gather user interaction data. Force Resistive Sensors were placed on the front panel and piezzo sensors were placed on the sides of the car’s body. Received user interaction was mapped onto a code via customized Arduino Board. Arduino code was commuicating with a sound patch that was built in MaxMSP/Jitter, and finally delivered into Ableton Live as Midi Data. In sum when a person taps onto a sensor that hides under the car’s surface, that interaction was turning into a percussion sound. There were tons of cables, sawing, soldering, coding and etc…
On the [website] there are some videos that show the project in action. Unfortunately all the text are in Turkish, we hope for an English, more international, version.
End-of-year engineering school projects often pique our interest for their creativity. It's not every day that they can carry a bassline, however. James McVay's robot project for his honors year at the Victoria University of Wellington, the supremely well-named MechBass, wouldn't have much trouble keeping up with a favorite band. It centers on a custom, Arduino-compatible board that controls the plucking, fretting and damping of four strings to faithfully recreate bass guitar sounds from MIDI input. The design even accounts for the unwanted noises of actuators and motors, while virtually everything was either 3D-printed or laser-cut just for the task at hand. Sounds good? There's more in the pipeline: an upcoming Swivel robot will experiment with different playing techniques, and McVay ultimately sees his work teaching us about robotic music's interaction with human performers. For now, we'll be happy with the video after the break and hope that MechBass takes requests.

Invention of a new Open Source mechanical musical instrument
Following the « DYI » trend, here comes a musical automaton created by [EricDuino]. This Arduino based autonomous robot is named « Line Follower Organ », « Orgue Suiveur de Ligne » in its maiden language.
What’s new with this instrument is that it moves along its partition in order to play it.
It’s still at a very early stage and it cannot play a full symphony or house music yet. Hopefully the Open Source community will soon make it play Electro Hop.
