2D Barcodes Part 2: mp3 and colours

Today, I am exploring Snapmaze that allows you to make 2D barcodes with different colours. Also, I tried to do a barcode with an mp3:

In addition, I think that everybody needs a positive phrase everyday, so here are different barcode with different colours to think more positive. To see this quotes or download the mp3 just use your mobile phone's camera.

Finally, I found Maestro that allows you to insert a location on a map and work on dimensions and colour!

A possible final use in a calendar to have a positive and maybe unknow phrase everyday/month

Fun with Tape-Heads

Hello all, for one of this weeks experiments I made a device for manually playing back magnetically stored data ( eg credit cards , cassette tapes, floppy disks, etc). This idea was taken from Nic Collin's Homemade Electronic Music book.

This was made using a tape head that was taken out of a standard cassestte player (preferably broken, as it definitely will be afterwards). Hopefully with the wires intact, we can then solder these onto a standard guitar lead which has been cut in half (about an inch of the outer coating stripped back ,the outer wires braided together, and then the inner coating stripped also about an inch).




I then made a sound board out of a cassette tape and a bit of cardboard (it is better if you mix a few together to give you a more varied sound). This was done by simply taking a cassette, cutting the tape at the opening, and wrapping it carefully around the piece of cardboard, until you have something that looks like this -



What we have done is essentially taken an analog mobile music playing device (the cassette player) and hacked it so that we can have more control about the sounds that we produce from the data provided. In effect, it acts a bit like a primitive sampler, allowing us to skip, scratch, speed up, slow down, and mash together tracks on top of each other.

Experiments like this are very simple, but allow us to consider all the data around us, as it can also sonify those old credit cards and magnetic data which sit collecting dust. Hacks like this also allow us to explore and understand sound and technology, by stripping it back to its bare components.

work in progress

I am working on what I think will become my main project. The project is an extension of the noisy self miking rhythm stick developed earlier this term. The concept is to develop a musical game, taking the idea of using dice to generate random patterns within a set of parameters, inspired by a set of poker dice which I have kept since I was 18.

The idea is to use reacTIVision to read fiducials from the faces of five dice, the values and location of which will be interpreted using Processing and this will be passed as midi messages to Ableton Live and used to trigger loops, and control the volume and position of each loop within the mix.

The concerns I have is to create a rich experience with the game; if it is just based on the possible permutations of the set, 7,776 combinations in all, then the game is limited and self reproducing. By using some of the information about the location of the dice relative to the table, based on the centre of the playing area, then I will incorporate a level of complexity which will render the repeatability almost impossible.

No pictures of the game yet, and the code is still a bit lumpy, but i intend to have this up and running in a couple of weeks.

First steps with Arduino or How to make a cheap, quick, awful synth!

This week I attempted to make the most basic synthesizer using the arduino, some potentiometers and a piezo. So heres the setup,

I put the three potentiometers in a circuit, with a ground and power supply. Then on a separate circuit we plug in a piezo. Each potentiometer is connected to an analog input so the values can be read, and the piezo is connected to a digital pin.

This is basically an upgrade and mish-mash of a few basic examples on potentiometers (http://arduino.cc/en/Tutorial/AnalogInput) and on tones (http://arduino.cc/en/Tutorial/Tone). The piezo generating tones depending on the values given by the potentiometers.




For this synth, as shown in the video, one potentiometer controls frequency (Hz), one duration of tone, and the other the frequency (time) of the tones. It makes a pretty horrible little sound, so I definitely wouldn't watch the whole minute of this video, but I am pretty impressed by how quick this sort of project can be put together.

Game Tour - Test 1: Greenwich 27 Feb

Hi everyone,

Here is a link to the blog where I am working on my final project of game-tours... Last week I made the first test for my final project, doing the Game-Tour in Greenwich, London.

You can visit this link to see photos and to understand how the project worked.

I'll improve some interface and narrative elements for the final project.

Brighton mobile site is now working

Hello, I fixed my problem with Google maps in my mobile site using Google Code (thanks to my beloved wife).
Now the site is online with a map, clock, tweets about the city, your tweets and a Google news widget about Brighton. Please, go to: http://elmundialista.cl/gobuk

Another interesting event - InterMus group

Hi everyone

We will be having a seminar on Monday 15th March, 4pm-5.30, in the Russell Building (room 12). There will be two talks, one from Frauke Behrendt (Media) and one from Paola Cannas (Music). All welcome.

Frauke Behrendt will be speaking on her work with sound-based creative use of mobile technology. Her talk is titled "A Taxonomy of Mobile Sound Art".

Paola Cannas's talk: "Technologies and performance: a vibrant interaction" is a reflection on her experiences, as a musicologist, with tools developed through interdisciplinary research.

Interesting events

Hi guys,

Just to let you know about this event - should be interesting ....

NATIONAL TESTING GROUNDS OF LIVE ART

Live Art and Music Event

Mikahil Karikis, Mitch & Parry, Kristin Sherman, Dori Deng and Meta Drcar

Saturday 13th March 2010

7:00pm - 10:00pm

£4

Boundaries, Fluidity and Dislocations are the focus for the programme, the commissioned artists explicitly exploring ideas around liminal access and departures: the boundaries of the body - and the distance between bodies, the exploration of sound and the confinements of our physicality, the limitations of the gallery space, of the self, of the other, of the individual and of group migrations in our geography, identities and disruption across the artistic and the non artistic.

For this Testing Grounds event Mikhail Karikis explores parallels between the nature of the medium of sound and politics of migration; thinking of sound as a perpetual immigrant, always travelling away from its place and material of origin, penetrating invisibly into spaces where it may not be welcome.

Kristin Sherman explores structures of power made manifest through intricate performance machines. Her work for Testing Grounds paints a dark and humorous portrayal of power and control, a system made of bodies, where each actor monitors the other. Taken to extremes, the work questions and challenges our notions of freedom.

Mitch & Parry's new working project examines the landscape of the body as a space for collecting and exhibiting the stains and marks of loss, love and labour, by developing their work of creating external discourse with internal bodily fluid - creating a tension between provoking and inviting the spectator.

Dori Deng and Meta Drcar 's Measuring series is a meditation on relations between space and different medias including the body, visuals and sound. The action of measuring is presented physically, but also through mathematical connections, of musical rhythm and time in order to change the dimension and the proportion of the gallery space, twisting our assumption or expectation of a given context.

Testing Grounds hopes to contribute to the richness of the South East region's Live Art scene by creating a place where audiences can glimpse the newest work, be provoked, discuss new ideas and socialise. This event is co-curated with Permanent, and supported by the Lighthouse and funded by Arts Council England South East.

Thinking about Mobile and Locative Media

... I think that it is more than media, than medium, it is part of our everyday life and it's really changing it.... Particularly I like the idea of mobile technology as a learning tool, playful tool, a medium to get in touch and to understand and live the city and our everyday life in a different and maybe better way....

location&relation

hello everyone, last week i have collected some information of friends location in brighton. i asked them to mark their living location at google map by using the same account.

Then i made a graphic which has some spots are just corresponding the exact location on google map. and the lines between the spots is referring to the relations between them, in other words, i know them all, but also some of them know each other. and if some people are just in a round circle, which they all know each other. So far i just done these...i feel headache now..mmmm .. and if anyone has any ideas to help me develop it further, im very thankful...
