Random Walk Generator Demo (ArdCore, Kraftzwerg, & A148)

October 28, 2012 · Posted in Uncategorized · Comment 

The Snazzy FX ArdCore is a Eurorack module based around the Arduino microcontroller. You can create programs (a.k.a. sketches) on your computer and upload them via USB into the module.

For this video, ‘chisel316′ loaded the Random Walk Generator sketch into the ArdCore and use it to modulate the VCOs on the Kraftzwerg. Also in play in this patch are the Kraftzwerg’s Dual cross-modulating LFOs and the Doepfer A148 Sample and Hold module.

“As you can see, I started expanding my modular setup. I’ve been collecting modules that I feel compliment the Kraftzwerg.”

The Beer Cans Keyboard Movie

October 23, 2012 · Posted in Uncategorized · Comment 

Do you have any idea of what you get if you combine 44 beer cans with an Arduino board and a Raspberry PI ?

We will tell you : fantastic user engagement!

We did this at Webstock, event which took place in Bucharest in September. Staropramen, one of the sponsors of the event asked us for an innovative way to offer a trip to Prague to one of the event’s guests.

So, we came up with a keyboard made out of 44 Staropramen beer cans. Each beer can was a key, and whenever someone touched it, the corresponding letter appeared on a large plasma screen (just like any regular computer keyboard).

And the surprise was fantastic! The user experience and engagement overcame any expectation. Every single person who attended Webstock tried the keyboard and participated to the contest.

Behind the scene, the system is built around an Arduino board and a few capacitive controllers (just like the ones which are inside smartphones’ touch screens), connected to a Raspberry PI board which controls the plasma screen display.

A movie and some photos took during the event can be found here -

Skube – A Last.fm & Spotify Radio

September 17, 2012 · Posted in Uncategorized · 1 Comment 

Rethinking home audio and understanding how and where people share music was the jumping point for creating Skube. We are moving more towards a digital and online music listening experience, current portable music players are not adapted for this environment. And sharing music in communal spaces is neither convenient nor easy, especially when we all have such different taste in music.

The result of our exploration is Skube, a music player that allows you to discover and share music and facilitates the decision process of picking tracks when in a communal setting.

It is a fully working prototype through the combination of using Arduino, Max/MSP and an XBee wireless network. We access the Last.fm API to populate the Skube with tracks and scrobble, and using their algorithms to find similar music when in Discover mode. Then using Applescript, we get Spotify to play the music. We use XBees for the wireless communication between the each Skubes and to the computer using custom software that manages all this.

SJS-ONE – new 8-bit mono synthesizer

July 25, 2012 · Posted in Uncategorized · Comment 

Here’s a new treat for 8bit synth fans, check out the SJS-ONE.

SJS-ONE is a software defined 8-bit mono synthesizer with a dual (series) MAX261, switch-cap filter, which we are, as far as we know, the only ones to use at this point in a DIY-synthesizer.

The synthesizer has some interesting history that has certainly colored its development and ultimately it’s sound. The initial version was developed as an instructional workshop for a synth-event called SyltJam in 2011. The workshop idea was to show people how quickly you can design the basic hardware and software required to produce a platform for versatile audio and music generation.

As it turned out, people liked it’s sound so much that we decided to refine the design – which more or less involved adding peripheral components to increase configurability and improve on stability and ESD, ground-mismatch and noise sensitivity while keeping the actual design minimal and simplistic.

It’s beginnings are as humble as it’s production – less than 50 of these have been made available and all parts are hand assembled and hand soldered, while the manual is hand drawn and cases hand painted.

Perhaps the most unique aspect of this synth is the choice of digital platform – the Arduino. We did not want to build something static and opted to keep the Arduino instead of adding an on-board microcontroller. Because this will make it so much easier to modify the functionality of the synth firmware provided by us, or to write your own software with a completely unique sound using the vast community support that is available for the Arduino platform.

All aspects of the synth can be fully controlled by designing your own custom firmware and we sincerely hope that people will share their firmware in the spirit of the open source and hardware that inspired us to drive this project from idea to final product.

Roland Juno 2 iPad controller with Arduino Ethernet demo

June 26, 2012 · Posted in Uncategorized · Comment 

Demo of a custom device build around Arduino in order to control the Roland Alpha Juno 2 via Wifi.

The Arduino connects the Juno2 to the Wifi network of the iPad via an Airport router, an Arduino Ethernet shield and a midi shield.

I used Touch OSC to design the controller.
Touch OSC sends OSC messages (e.g /jun/DCO_Range 2.000) which are translated by the Arduino into Midi SysEx messages.
But the Arduino also translates Midi sysex messages from the Juno 2 into OSC messages (sort of loopback) so that when you change the patch on the Juno2, faders automatically move to the right position !

The code and detailled instructions will soon be published on http://4colors.free.fr
The control design mimics Roland PG300, but better !

Retro Joy – Serial Serendipity DIY

April 13, 2012 · Posted in Uncategorized · Comment 

Some fun with an old joystick and a sampler made from an Arduino + the Adafruit Waveshield.

Curious about what the Adafruit is? Here’s a description:

Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It’s low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.

This shield is a kit, and comes with all parts you need to build it. Arduino, SD card, tools, speaker and headphones are not included. It is fairly easy to construct and anyone with a successful soldering project under their belt should be able to build it.

The shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when serial data is received, etc. Audio is played asynchronously as an interrupt, so the Arduino can perform tasks while the audio is playing.

NOISY JELLY

March 31, 2012 · Posted in Uncategorized · Comment 

This project is a fully working prototype made with Arduino and Max/Msp, there are absolut no sound editing in the video…

More picture at this flickr set (flickr.com/photos/raphaelplu/sets/72157629621382055/)
And download the Project pdf here (pluvinage.eu/NOISYJELLY_presskit.pdf)

Noisy jelly is a game where the player has to cook and shape his own musical material, based on coloured jelly.

With this noisy chemistry lab, the gamer will create his own jelly with water and a few grams of agar agar powder. After added different color, the mix is then pour in the molds. 10 min later, the jelly shape can then be placed on the game board,and by touching the shape, the gamer will activate different sounds.

Technically, the game board is a capacitive sensor, and the variations of the shape and their salt concentration, the distance and the strength of the finger contact are detected and transform into an audio signal.
This object aims to demonstrate that electronic can have a new aesthetic, and be envisaged as a malleable material, which has to be manipulated and experimented.

DODECAUDION – new audiovisual controller

February 28, 2012 · Posted in Uncategorized · Comment 

DODECAUDION
a project by panGenerator / HEDOCO product.
pangenerator.com
hedoco.com

Dodecaudion is a spatial audiovisual controller based on such technologies as infrared distance sensors, arduino, bluetooth, processing and osc.

Most of the sound in this video was recorded live and edited/postproduced later on.
(you’ll find live and uncut performance played during hackdays here: blip.tv/hackdays/dodecaudion-koncert-5556815 – please mind that sound setup and recording weren’t optimal though )

The project is in alpha phase right now but should be ready for production in following months and will be available via HEDOCO online shop.

Dodecaudion is totally opensourced:
MIT license – source code.
Creative Commons (CC BY-NC-SA) – form design, PCB layout & everything else.

You’ll find source code, CAD documentation and PCB schematics on github ( please note however that they still need some cleanup, we’ll post an update soon ).
github.com/panGenerator/dodecaudion

The heart of Dodecaudion is an Arduino and open source software. The Arduino collects data from all the Dodecaudion sensors and sends them to a computer.

Dodecaudion connects via Blutooth to computers. Messages are translated and retransmitted via OSC (software for Mac OSX and Windows available for download).

Included:

  • Arduino Uno,
  • Dodecaudion Shield rev. 2.0,
  • Alluminium and polymer composites housing,
  • Power source (230 V for EU continental outlets)
  • USB cable (not neccesary for normal operation but handy for tinkering with microprocessor code)

It’s available now and priced at 5,000 PLN, which translates into around US $1,600.
