Don’t worry, he’s mostly harm­less!
Basílio, a good­fella, a Lob­ster, a good friend and a Google SketchUp ninja!
Well, yes­ter­day was Alt­Lab meetup day, and the plan was: make a 3D model of an X axis car­riage for a mini-mendel.
It was a suc­cess! After a few hours using Google SketchUp, we’ve man­aged to cre­ate a darn good look­ing car­riage.
The next step will be print it and assem­ble it.

I’m not in the mood…

At least it’s what she said! Vio­leta… the printer, I mean :)
From the begin­ning, tues­day it’s meet­ing day atAlt­Lab and I’ve dis­cussed with Mauri­cio the pos­si­bil­ity of using the Mini-Mendel with an adapter, a Pen Holder to write the pcb’s lay­outs. The X axis car­riage from the Mini-Mendel was dis­as­sem­bled and after I’ve fin­ished assem­ble it, it looked a lit­tle wob­bly, and we don’t want a wob­bly printer!
So, Thin­gi­verse to the res­cue, and we found theMendel Mini-Carriage, and of we go… to the Maker­bot!!!
This was my first inter­ac­tion with a 3d Printer, and every­thing went well… until… when the print reached about 1cm of height, the extruder decided stop the extru­sion… damn!
We started over, but there was a sus­pi­cion over the lap­top, so we’ve tried using the SD Card to print… it didn’t work! Now the sus­pect is the ver­sion 3 firmware… and the lap­top… it’s a cabala or lack of luck :p
Did we give up? No, of course not, we’ve selected a smaller piece of the Mini-Carriage and pressed “BUILD”, and all went as expected, the first piece of the Mini-carriage was a suc­cess!
Let’s try another… and all went well.. until the 1cm of height… the extruder failed again :p
It was get­ting late, so we’ve closed the shop for the day… err… night.
But not every­thing was lost, we’ve plot­ted a plan to develop a Gen8 elec­tron­ics, just wait for it :)

RepRap Gen7 PCB… check!

Today went back to Alt­Lab for a lit­tle learn­ing expe­ri­ence. A great friend of mine, Fer­nando Afonso, came to Lis­bon to the launch of MEO Kanal, a prod­uct he helped bring­ing to life. Since he was here, he was invited by Alt­Lab to give a small work­shop on “PCB Mak­ing… The Fer­nando Afonso way”. :)The method used was Toner Trans­fer, where you print the cir­cuit lay­out with a laser printer on cheap mag­a­zine paper (the more glossier is bet­ter), then, with the toner side over the cop­per side and woot… the “sand­wich” off it go into a slightly mod­i­fied lam­i­na­tor (around 10 times) and the it’s sub­merged in freez­ing cold water.The low qual­ity mag­a­zine paper it’s eas­ily scrubbed off the pcb and it’s ready to the acid bath.
We used Acid Cupric Chlo­ride as etchant, when the pcb is sub­merged  it turns into a… kryp­tonite green… spooky I say!

In the end we’ve got a Gen­er­a­tion 7 Elec­tron­ics pcb for the Prusa Air… next step, buy the com­po­nents and sol­der­ing it :D

AZ Labs showcase @ Vila Verde

Text by Fil­ipe Cruz

On the 25 and 26 Jan­u­ary, AZ Labs show­cased some projects at the library of Vila Verde. This show­case was the first step in a series of inia­tives pro­moted by Casa do Con­hec­i­mento in Vila Verde in colab­o­ra­tion with Audiên­cia Zero. 500 stu­dents from local schools were brought to a secret room in the munic­i­pal library to dis­cover cre­ative, artis­tic and open source appli­ca­tions of tech­nol­ogy we had setup to show them.

The response from the stu­dents, teach­ers and orga­niz­ing comit­tee was great and we look for­ward to colab­o­rate some more with the peo­ple of Vila Verde in the near future!

In total we show­cased 7 projects.

Draw­dio – An eso­teric elec­tronic instru­ment invented by some folks at MIT explor­ing the con­duc­tiv­ity of graf­fite on paper or just com­mon water. The user closes the elec­tronic cir­cuit through touch, trig­ger­ing sound through a small speaker. Show­cased by Ricardo Lobo and João Gonçalves.

Ground­Spines Graf­fiti – The laser tag­ging pro­to­type devel­oped at xDA, inspired by theGRL laser tag sys­tem. This project was orig­i­nally devel­oped by Tiago Serra, Tony Gonçalves and Vic­tor Mar­tins to beau­tify aban­doned build­ings in Coim­bra. Show­cased by Pedro Salgado.

RC Micro Machines – Orig­i­nally devel­oped through a sprint ses­sion with peo­ple from the dif­fer­ent AZ Labs, main­tained by Nuno Bar­ros, Ricardo Lobo, João Gonçalves and Pedro Sal­gado. Show­cased by Nuno Barros.

Anon­Mir­ror – An inter­ac­tive instal­la­tion about social activism in our soci­ety. Made by Fil­ipe Cruz using Open­Frame­works, Kinect and a wrap­per devel­oped by Vic­tor Martins.

Maker­Bot – Ricardo Lobo show­cased and did some live main­te­nance fixes on “Cata­rina”, one of the two AZ Labs Cup­cake Maker­bots we have. Print­ing some whis­tles and show­ingThingiev­erse.

New Picasso – A kinect con­trolled robot that paints the floor. Users wave their hands in front of the kinect to send com­mands through Arduino to the servo motors of the robot. Project by Guil­herme Mar­tins, Pedro Sal­gado and João Gonçalves.

Tele­forma – Project by Ricardo Lobo, João Gonçalves and Mécia Sá deal­ing with the rela­tion­ship that peo­ple have with speech and con­ver­sa­tion. The project is based on a mechan­i­cal phys­i­cal inter­face that allows two users to trans­late visu­ally the form of their speech.

AZ Labs @ O Espaço do Tempo

The AZ Labs res­i­dency at Espaço do Tempo in Montemor-o-Novo is sadly over for now. Folks have been work­ing hard to fin­ish things up for the proto exhi­bi­tion of projects we had on Saturday.

A few projects were shelved or aban­doned for dif­fer­ent rea­sons. Not sta­ble enough, not enough time, no right mate­ri­als, not enough beer. In the end were left with 9 projects.

AR Cubes — André Sier devel­oped a few exper­i­ments with cubes glued with printed aug­mented real­ity fidu­cial mark­ers. Dif­fer­ent mark­ers trig­ger dif­fer­ent effects. You can play with them to make dif­fer­ent com­bi­na­tions of objects and lines inter­act­ing with each other.

  

Track­ing Head — Tiago Serra, Andrea Inocên­cio and Mauri­cio Mar­tins worked on a manequin head res­cued dur­ing a dump­ster div­ing ses­sion. They equipped a box with IR leds and use a cam­era with fil­ters to track the move­ment of the box. With these val­ues they send rota­tion infor­ma­tion to a servo motor equiped in the base of the manequin head. The same val­ues are also sent to a soft­ware that selects a cor­re­spond­ing angle photo which is pro­jected in the manequin. This sys­tem makes the freaky manequin head rotate in the direc­tion of the object.

Talk­ing Head — Next to the Track­ing Head we have a speaker box equipped wih an arduino, an ir receiver and a wave shield. When the box han­dled by the user aims at the speaker box it trig­gers ran­dom sam­ples from a sam­ple pool, giv­ing the illu­sion that the head itself is talk­ing. Mauri­cio, André, Fil­ipe, João and Rita worked on this project.

Track­ing Boids — The floor of the Track­ing Head space is cov­ered with small light spots fly­ing around. These boids, pro­grammed by André Sier may look like ran­dom disco lights on first glance but when some­one moves into the cam­era they flock towards the user.

  

Micro CNC — Tiago Rorke had been work­ing on a Micro CNC project, pieces printed with the Maker­bot. Tereza Car­doso gave him a hand mak­ing a project out of it by tak­ing pho­tos of the atten­ders of the res­i­dency, down­grad­ing them to vec­tor for­mat and hav­ing the micro cnc sketch them. They are drawn on the walls of the res­i­dency itself, along with qr code link­ing to video inter­views talk­ing about each per­sons involve­ment with the dif­fer­ent projects.

Paint Video Sig­nals — Andrea Inocên­cio recorded some short videos of red blue and black paint being applied to dif­fer­ent medi­ums (water, paper, table). Fil­ipe Cruz did a lit­tle pro­cess­ing sketch to extract midi val­ues from a grid of pix­els in the video and send them to reak­tor. Some gen­er­a­tive sound tests were recorded and mixed into a video dvd.

Blip Blop Blir Boxes — André Sier and Mauri­cio Mar­tins worked on a few small boxes packed with an Arduino, IR sen­sors, LEDs and speak­ers. Boxes point­ing to each other make the LEDs change their color. A third box pointed to the pre­vi­ous boxes makes them give out some blips and blops sounds.

    

O mundo é em cada instante o que ele não pode não ser.” — A project con­ceived by Patri­cia Proença con­sist­ing of a hand drawn ani­ma­tion of a tree grow­ing being pro­jected into a wall. The ani­ma­tion is trig­gered when a water­ing can equiped with a cell­phone is tilted into an alien plant object. Tiago Serra gave her a hand with the tech­ni­cal implementation.

Trailchi — Guil­herme Car­taxo and Sónia Malaquias been work­ing for while on their project involv­ing long expo­sions to tai chi ses­sions per­formed in the dark with a sword and suit equipped with 12 LEDs. The cap­tured ani­ma­tions makes some beau­ti­ful light trails art. Also helps analyse the motion of the session.

Day three is already upon us at the AZ Labs Res­i­dency. Folks still hap­pily hack­ing away day and night.

Run to the local chi­nese store brought back some hack­able good­ies like col­or­ful balls, a giant rubik’s cube and some wooden boxes. Andrea Inocên­cio was assigned to drilling duty after fin­ish­ing up with the manequin head. Ricardo Webbens left behind his radio loca­tion arduino cir­cuit pro­to­types for me to test.

César Coelho took the time to learn some new soft­ware stuff. Tiago Serra is cur­rently try­ing to make the kinect and the arduino talk with each other and make some annoy­ing sinus sounds. André Sier spent the after­noon hack­ing with Mauri­cio Mar­tins pro­gram­ming the arduinos with ir detec­tion to give some ran­dom blips and blops.

Tiago Rorke is almost fin­ished with print­ing and sand­ing the hard­ware of his rev­o­lu­tion­ary Micro CNC. Ricardo Lobo tried des­per­atly to get the other Maker­bot work­ing. Pedro Ângelo sec­cluded him­self to code some kinect stuff for Play With Fire. Fil­ipe Cruz spent some time test­ing new ver­sions of kinect libraries and ran­dom iPad development.

Ivo Andrade dropped by to enhance his project of the boy sit­ting on a metal cube. Patri­cia Proença sketched some con­cept art. Other folks were also walk­ing around look­ing busy and dis­cussing ideas. 7 more days to go.

AZ Labs are back in res­i­dency at Montemor-o-Novo. This time we are try­ing to have a con­nect­ing theme for the cre­ative tech­nol­ogy hack­ing insan­ity. The plan for the next 10 days is to brain­storm, con­cep­tu­al­ize and pro­to­type project ideas for tan­gi­ble objects that can inter­act with each other and the environment.

We have folks attend­ing with all sorts of back­grounds: com­puter sci­ence, plas­tic arts, per­for­mance arts, elec­tron­ics, indus­trial fab­ri­ca­tion, graphic design, sound design, sta­tis­tics, soci­ol­ogy. We barely had time to intro­duce our­selves to the first timers and new ideas are already brew­ing. Plans for infrared com­mu­ni­ca­tion. Aug­mented real­ity envi­ron­ments. Radio sig­nal tri­an­gu­la­tions. LED boards and cubes. Mul­ti­ple kinect abuse. Let us wait and see into what these ideas will mature into.

Right now it’s 2 am, some folks already went to sleep while oth­ers are hard at work on per­sonal projects. Using one of the Maker­bots to print parts to build a Micro CNC. Try­ing to get the larger CNC work­ing again. Hack­ing mal­func­tion­ing audio adap­tors to cre­ate con­tact micro­phones. Imple­ment­ing some tan­gi­ble inter­ac­tion with the kinect. Test­ing out some things with Arduinos. Fail­ing to install ofx­P­TAM. The list goes on.

True hack­ing knows no sleep.

SketchChair Hackday

SketchChair Hack­day por Tiago Rorke

Gostava de saber se alguém quer ir ao FabLab no dia 6 de Janeiro, para umas brincadeiras

com SketchChair, fazer cadeiras-miniatura, ou mesmo em tamanho real, usando as máquinas que lá há.

 

 

Este dia estava mar­cado para um SketchChair work­shop público, mas infe­liz­mente a máquina de corte a laser, que era fun­da­men­tal para o workshop, está avari­ada e não pode ser usada. Mesmo assim, que­ria aproveitar o dia, por­tanto, se alguém quiser par­tic­i­par e ir lá brin­car um bocado com design de móveis e fab­ri­cação dig­i­tal, é questão de combinarmos!

 

 

Se alguém estiver inter­es­sado em fazer uma cadeira em tamanho real, diga-me alguma coisa. Podemos procu­rar mate­ri­ais e preparar tudo no próprio dia, e seria pos­sível fazer duas (ou mais) cadeiras nesse mesmo dia, depen­dendo do design. Fiz um pro­tótipo esta sem­ana em Valchro­mat, um mate­r­ial fab­ri­cado em Nazaré que fun­cio­nou muito bem e tem cor > the lit­tle blue chair. Caso alguém esteja inter­es­sado, posso ten­tar pedir mais pla­cas para ter no FabLab.

 

 

Obri­gado e abraços para todos!

Our founder Cata­rina Mota is the new co-chair of the Open Hard­ware Sum­mit 2012 :)

 

New chairs of the Open Hard­ware Sum­mit 2012 | Cata­rina Mota & Dustyn Roberts

Pass­ing the torch! | Open Hard­ware Summit

After two amaz­ing and inspir­ing iter­a­tions (2011 and 2010), we are excited to announce we are pass­ing the Open Hard­ware Sum­mit torch.


With Catarina’s exper­tise in Open Mate­ri­als, and Dustyn’s work in open mech­a­nisms and robot­ics, each will bring a unique new dimen­sion to the term “Open Hard­ware” and together broaden the rel­e­vance and reach of our move­ment and sum­mit.
Thank you all for the sup­port, we can­not stress enough that this is your move­ment, and every­one here has helped make it hap­pen. The sup­port for the Sum­mit, from help­ing hands to dona­tions, made it pos­si­ble. Please con­tinue to sup­port the move­ment as it goes for­ward.
Put your hands together for Cata­rina and Dustyn!
Cheers,
Ali­cia & Ayah

TANGÍVEIS — Residência AZ 2012

A Audiên­cia Zero vai realizar mais uma residên­cia artís­tica mul­ti­dis­ci­pli­nar em O Espaço do Tempo (Montemor-o-Novo), entre os dias 14 a 22 de Janeiro.

Nesta edição, ter­e­mos uma novi­dade :) Enquanto nas edições ante­ri­ores os par­tic­i­pantes eram con­vi­da­dos a desen­volver qual­quer tipo de pro­jecto, indi­vid­ual ou colec­ti­va­mente, nas áreas de elec­trónica, com­putação física, insta­lações inter­ac­ti­vas, etc., este ano propo­mos tam­bém um objec­tivo comum: o desen­volvi­mento de inter­acções tangíveis, através da con­strução de objec­tos e espaços inter­ac­tivos capazes de demon­strar que um objecto pode causar inter­acções dis­tin­tas em espaços dis­tin­tos. A ideia é fazer com que cada objecto a desen­volver inter­aja de forma difer­en­ci­ada nos espaços cri­a­dos, ou que os objec­tos inter­a­jam entre eles próprios.

Deix­amos aqui alguns exem­p­los de ideias a abordar.

Imag­ine um objecto a ser lev­ado para deter­mi­nado espaço onde está uma luz robo­t­i­zada. Quando o objecto é “recon­hecido” no espaço, a luz robo­t­i­zada passa a seguir a pes­soa que o car­rega. Se o objecto for dado a outra pes­soa, passa então ela a ser seguida pela luz.


É pos­sível desen­volver out­ras inter­acções semel­hantes, por exemplo:

  • Ao apon­tar os objec­tos uns para os out­ros, os objec­tos reagem com som, luzes, etc.;
  • Ao alterar a sua posição no espaço, o objecto reage com som, luzes, etc.;
  • Ao alterar a sua posição no espaço, o objecto faz com que o espaço reaja com pro­jecções de vídeo, som, luzes, etc.;
  • A mesma posição no espaço pode causar inter­acções difer­entes com cada um dos objectos.

Podem ser desen­volvi­das diver­sas nar­ra­ti­vas – artís­ti­cas, didác­ti­cas, de “gam­ing”, etc.

Para o desen­volvi­mento destes objec­tos e espaços, propõem-se vários tipos de tecnologias:

  • Elec­trónica;
  • Com­putação Física;
  • Insta­lações Interactivas;
  • Robótica;
  • Visão por Computador;
  • Visu­al­iza­ção de Dados.

Serão disponi­bi­liza­dos (a título de emprés­timo) com­puta­dores, Arduínos, sen­sores e mate­r­ial elec­trónico, pro­jec­tores de vídeo, sis­temas de áudio, etc. para uso exlu­sivo no local da residên­cia e durante o período de desen­volvi­mento dos projectos.

A residên­cia é des­ti­nada aos actu­ais mem­bros da rede AZ Labs ou a quem se iden­ti­fique com o ojec­tivo pro­posto e tenha inter­esse em con­hecer o tra­balho por nós desen­volvido. As vagas na residên­cia estão lim­i­tadas a 15.

Todos os par­tic­i­pantes des­fru­tam de alo­ja­mento, pequeno almoço e almoço durante o período da residência.
