Glitch Safari is a flickr and vimeo group moderated by artists Antonio Roberts and Jeff Donaldson.

From the group description:

Displays will glitch in our modern, urban landscape. These occurrences generally go unnoticed by society or are ignored as technological failure.
Glitch Safari is a group that sees the magical quality in these sometimes fleeting instances and celebrates this aesthetic as machine art.

Submissions are focused on public display errors (more so of the pattern variety than the common windows boot screen type) that are unprovoked or, natural:

We're on the hunt for glitches from across the globe! Post pictures and videos of glitches found on displays, signs and machines.

Please geo tag your submissions and, for more points, add a description of where you found it*

Submit your found glitches to the flickr and vimeo pools today!

thanks i will try and get it to work.
i have no and nc contacts on my limit switches, is it possible to turn servo in opposite direction when limit is on and not turn again till other limit is off??? if that makes sense

Hello. I just got my relay shield and having problem putting wires in right places. How exacly do i put the wires? Where do i put the 220v? It says that pin 5 is OUTPUT 1, pin 6 is OUTPUT 2 etc. Still im not exacly sure how this relay works. Could som...

Arduino donations and values for a growing ecosystem based on open source

Posted: 10 Jun 2013 02:40 AM PDT

Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. Arduino and many other projects share a similar philosophy of creating free open source tools allowing non-technical people to work with hardware and software.

Arduino is based on the contribution of many other open source projects. We are grateful to these efforts and want to support them. Since we're not always able to contribute code or technical support we want to do it through donations.

From now on every year Arduino will donate to the open source projects it collaborates with and shares Arduino approach and philosophy.

In 2013 the institutions to which Arduino donated 2,500 dollars are the following:

Processing is an open source programming language and integrated development environment (IDE) built for the electronic arts, new media art, and visual design communities with the purpose of teaching the fundamentals of computer programming in a visual context. The project was initiated in 2001 by Casey Reas and Benjamin Fry.

The Arduino IDE is derived from the Processing IDE.

The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom and to defend the rights of all free software users.

The foundation has created the licenses used by Arduino and created the GCC compiler which is used as a compiler for the Arduino code.

Creative Commons is a nonprofit organization that enables the sharing and use of creativity and knowledge through free legal tools. Creative Commons develops, supports, and stewards legal and technical infrastructure that maximizes digital creativity, sharing, and innovation.

Both the Arduino hardware reference designs and documentation are distributed under a Creative Commons license Attribution-ShareAlike 2.5.

Fritzing is an open-source hardware initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics: a software tool, a community website and services in the spirit of Processing and Arduino, fostering an ecosystem that allows users to document their prototypes and share them with others.

Fritzing is used for illustrations in Arduino documentation.

PmWiki is a wiki-based system for collaborative creation and maintenance of websites originally developed by Patrick R. Michaud.

PmWiki is the Arduino official wiki since 2004.

Linux foundation promotes, protects and advances Linux by marshaling the resources of its members and the open source development community to ensure Linux remains free and technically advanced.

Arduino has always been a fan of Linux and many users of Arduino use Linux. Furthermore, the new Arduino Yún is the first member of a family of wifi products combining the power Linux with ease of use of Arduino.

And finally,

CERN for the improvement of KiCad. Kicad is a free and open source software PCB design tool. The objective of this development project is to enhance Kicad to make it an efficient tool for PCB design, which people can use to share their design information without compromising productivity. This contribution is part of CERN's broader efforts in Open Source Hardware.

This is just a first small step towards more contributions to keep the open source ecosystem growing, in the coming years the amount we will devote to donations will keep increasing based on our revenues.

We hope more companies that are involved in Open Source Hardware and Software will follow our example.

Re: HOW DO YOU USE BUTTON TO SWITCH BETWEEN 4 SEQUENCES

Code:

const int ledPin1 = 13

const int pushButton = 2

All statements end with ;

You can only have one setup() function and one loop() function.

Ignoring for the moment what you want to have happen when the switch has been ...

Yuri Landman’s Instruments

Posted: 10 Jun 2013 02:00 AM PDT

Twister, Moodswinger and Burner Harp Guitars by experimental luthier Yuri Landman.

Yuri Landman is an experimental instrument builder and musician. Based on prepared guitar techniques, he built his first instrument in 2001 to solve the inaccuracy of instant preparations. In 2012 Yuri formed the 2-piece band Bismuth with multi-instrumentalist Arnold van de Velde. In the same year he started his infamous Strat Eraser Project to help musicians get rid off their useless gear.

In 2006 he got in contact with the band Liars. Developed over six years of prototyping, he fully realized the Moodswinger for them with commissions from numerous other musicians to follow. Yuri has custom built derivatives for such musical luminaries as Lou Barlow, Sonic Youth, dEUS, The Dodos and many more. Since 2009 Yuri leads practical building workshops — The Home Swinger Project – where people build their own electric instrument, often followed by an afternoon rehearsal on the second day and a 40 minute ensemble performance with multiple Home Swingers, drums, basses, and guitars in the tradition of the Rhys Chatham and Glenn Branca compositions.

Check out his official website here and watch a TEDxTalk Landman gave last year.

Look at your code. You are reading one switch, and, if it is not pressed, you start the motor moving, wait, stop the motor, and wait some more. Then, you read the other switch, and make the motor run the other way a little bit.

You need a while loop th...

Lumanoise: Three New Synths from Tonylight

Posted: 10 Jun 2013 01:00 AM PDT

Lumanoise V1

The lumanise V1 have one square osc, one 12bit sawtooth osc.
The oscillators pitch is controlled by a photo resistor, each oscillator have a volume pot.
A 12 db low pass resonant filter, specially developed by LEP for the project lumanoise, the filter cut-off can be controlled by the potentiometer or the photoresistor.

Lumanoise V2

The lumanoise V2 heve one square osc, one 12bit sawtooth osc. and 2 trautonium like sub oscillator.
We were inspired by the great Oskar Sala Trautonium synth oscillator.
We use one master oscillator under LDR control and 2 sub oscillator, where you can set the frequency.
The oscillators pitch is controlled by a photo resistor, each oscillator have a volume pot.
A 12 db low pass resonant filter, the filter cut-off can be controlled by the potentiometer or the photoresistor.

808 cymbal drone generator

The 808 cymbal drone generator use 6 fixed frequency square wave oscillators.
The oscillator frequency came from the cluster oscillator circuit used in the TR808 drum machine for creating cymbal sound, in fact these are the harmonic frequencies of the sounds of metal plate.
Each oscillators have a volume pot. and the 12 db low pass resonant filter, the filter cut-off can be controlled by the potentiometer or the photoresistor.

The Lumanoise box are made of plywood 3mm laser cut, different textures will be available soon.
