<p>O festival <a href="http://codebits.eu">Codebits</a> organizado pela SAPO é um evento que pretende juntar pessoas de áreas creativas e tecnologias inovadoras num ambiente informal e relaxado em Lisboa. Durante os 3 dias, haverá espaço para talks, workshops, concursos de programação, hacking muita animação e espaço para acampamento, descanso e alimentação.</p>
<p>Em 2009 participei no <a href="http://codebits.eu">Codebits</a> e recomendo vivamente a experiência. Foi uma experiência surpreendente, e no meio de uma conversa informal juntei-me ao projecto <a href="http://spacebits.eu">Spacebits</a>. Se ainda não o conhecem, aproveitem para ver as mais belas fotos de <a href="http://spacebits.eu/page/flight1photos.html">Portugal visto do Espaço</a> <img src='http://inmotion.pt/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>O <a href="http://codebits.eu/s/register">registo</a> no evento é gratuito e a lista de temas a apresentar ainda está aberta a novas propostas.</p>
<p>/// ENGLISH</p>
<p><a href="http://codebits.eu">Codebits</a> is an amazing event bringing creative people and technology all together in a relaxed and friendly environment in Lisbon, Portugal.</p>
<p>In short: <em>&#8220;3 days. 24 hours a day. Talks. Workshops. Lots of food and beverages. 24 hour programming/hacking competition. Quizz Show. Rock Band Contest. Lots of gaming consoles. More food. More beverages. More coding. Sleeping areas. More fun. An unforgettable experience.&#8221;</em></p>

<p>In the last six months i&#8217;ve been working as hell, running an online store, giving lectures at the <a href="http://www.ufp.pt/">UFP</a> and working in a little project called <a href="http://spacebits.eu">Spacebits</a>. If the name sounds familiar, that&#8217;s because it is. <a href="http://spacebits.eu">Spacebits</a> project spanned from a casual meeting in <a href="http://codebits.eu">Codebits 2009</a>. For those who missed, <a href="http://codebits.eu">Codebits</a> where the BEST 3-days about web, technology, creativity and fun.</p>

<p>For starters it will be a live Internet event, scheduled to take flight on <strong>30th of May, 2010, 11AM GMT on Castro Verde</strong>.

The ADDAC is an Arduino based Analog-to-Digital-to-Analog 16bit 8 independent Outputs Modular USB Interface. Sounds interesting? That's because it is in fact an amazing piece of hardware. But before getting into more details we need to remember the days of analog synthesizer, the world of analog synthesizers.

<p><a href="http://andregoncalves.info/">André Gonçalves</a> as presented us again with is latest work: the <a href="http://andregoncalves.info/addac/">ADDAC System</a>. The ADDAC is an Arduino based Analog-to-Digital-to-Analog 16bit 8 independent Outputs Modular USB Interface. Sounds interesting? That&#8217;s because it is in fact an amazing piece of hardware. But before getting into more details we need to remember the days of analog synthesizer, the world of analog synthesizers.</p>
<p>On those days there was no MIDI protocol and most of the synthesizer where controlled using a protocol called Control Voltage. In the 70&#8217;s it was common to re-connect your synthesizer modules, a processes called patching. Modern live performance tools as the Pd and Max/MSP are build upon this concept, virtually controlling any kind of MIDI or OSC device.</p>
<p>André passion for music has turned into the <a href="http://andregoncalves.info/addac/">ADDAC</a>, an interface from the analog-to-digital and from digital-to-analog, opening the possibility to control any analog synthesizer from a computer or from your Arduino. The <a href="http://andregoncalves.info/addac/">ADDAC</a> has support for CV input, CV output, supports OSC (using the <a href="http://www.inmotion.pt/store/product_info.php?cPath=42&amp;products_id=78">Ethernet Shield</a>) and can be controlled using the NunChuck. Let us tweet to your Moog&#8230;</p>

			<content:encoded><![CDATA[<p><a href="http://www.andregoncalves.info/">André Gonçalves</a> is a Lisbon based sound and media artist that creates <a href="http://www.andregoncalves.info/installationsSet.htm">interactive installations</a>. For him, the Arduino is a tool, a window of experiment that offers a chance to peek and poke, experiment and be creative. Illustrative examples of his work can be found in installations has &#8220;<a href="http://www.andregoncalves.info/installations/daisies/index.html">I Thought Some Daisies Might Cheer You Up</a>&#8221; and photographic experiments in <a href="http://www.andregoncalves.info/installations/untitled06_portable/index.html">Polaroid films</a>.</p>
<p>As a true artist, he design and build most of the hardware used in his works. The <a href="http://www.andregoncalves.info/ag_blog/?page_id=61">Envelope Follower</a> and the <a href="http://www.andregoncalves.info/ag_blog/?page_id=67">opto-coupled H-Bridge</a> shields are perfect examples of dedicated work, improvement and openness to the rest of us. These are now available for sale in his website and very soon at the inmotion.pt</p>
<p>In the synth world an Envelope Follower is used to detect the amplitude variations of an incoming signal to produce a control signal that resembles those variations. It features two mono or one stereo channel with individual volume and decay controls for fine tune, meaning that it follows the audio amplitude creating a voltage output that resembles the audio signal volume, between 0 and +5V. getting the volume is easy as doing analogRead(&#8230;) From light control to motor speed you can easily allow every object to react to any kind of  sound input.</p>
<p>The H-Bridge is another tool for the savvy user. It features two opto-coupled channels and can control up to 10A and voltages from 5-12V. With the opto-coupler you can now safely control every motor, even those of make lot&#8217;s of line noise. You no longer need to use the capacitor between the motor input and your Arduino is no longer susceptible to random reboots. Gentleman, start your engines&#8230;</p>
