Function2Form

Function2Form is the work created by Victor Martins for The Viewer, a magazine focused on photography and video. A work of generative art and photography as claimed by the author (me).

Function2Form is a work on form and shape generation from the subdivision of space and image analysis. It has no rules other than the creation/deformation of limited space. It’s a study on photography. It’s a random case of geometry generation and a study of differences for different parameters and areas. Based on randomness i would say these are unique and lost generated pieces of a kind.

AZ Residency Day 7 – We’ll Be Back

Yesterday’s late night hacking session managed to deliver some results. Baco’s Mechanism was complete and so, to celebrate, refreshments were in order, plus waking up to join the party anyone who was already asleep. The troublemakers delivered a personalized rendition of the classic, also previously abused for remixes, Vitor Espadinha “Recordar é Viver”.

Today was a sad day, everyone who was taking their time getting up was also woken up with a new personalized rendition of Vitor Espadinha’s “Recordar é Viver”, payback is a bitch. We packed up and headed down to a local restaurant for the last meal of this week’s residency. With promises of returning in June for 10 more days of collaborative hacking.

AZ Residency Day 6 – Vitor Espadinha Si Teh Luv

Day 6 started pretty late. At 10 o clock we had a mini makerbot workshop to replace a broken extruder piece, but most folks were still asleep from staying up till late working on the Piano Cocktail, so only Catarina and Guilherme managed to attend and fix the broken piece.

Late arrivers João, Vitor and Mécia arrived shortly after while i tried to finish up some work on the haiku generator and Mauricio was working on the keyboard mischiefs with Catarina. Guilherme was already gone, he had to prepare his work for the Talk Show piece downtown. A little while later Mónica and Francesco decided to join us in discovering where Blackbox was actually, we got abit lost but managed to all arrive on time.

The piece was pretty great! Well produced and performed! So props to the ones involved was in order and back we went to our residency for some food and project pushing. Guilherme and Catarina still messing with the Makerbot; Mónica blowing plants; Filipe, Ricardo and Mauricio finishing up the Piano Cocktail; Luis and João working on the meal tracking ballet system; Pedro helping out Jorge with his Arduino issues; and me trying out a couple new remixes of the remix.

Before dinner we also had a short visit from a few performance related folks, seemingly guests from our host and friend here at Espaço do Tempo, Rui Horta. They seemed pretty interested in our adventures with the new technologies, especially in terms of networking and open source mentality.

There was no catering on Saturday aparently, so things were abit more erratic but it all worked out in the end. We managed to organize a nice dinner event with nearly everyone present, and proceeded directly to judging the world famous Vitor Espadinha “Recordar é Viver” remix compo, participating was me, Sérgio and the proclaimed winner mister Pedro Ângelo.

90’s electro night proceeds as i type, everyone seems to be happily working on their projects and/or enjoying their refreshments. It sucks hard that tomorrow is the last day already. As a curiosity note, it seems 95% of the folks here at the residency use Mac’s, even if one of them does have Linux installed.

AZ Residency Day 5 – Mistos de Porco Preto Reprise

Yesterday’s dinner didn’t go so well. We went to pick up a few doses of “Mistos de Porco Preto” (means something like Mix of Dark Pig in English) at this local restaurant which we had scouted on Tuesday as serving pretty well. But we had an unfortunate surprise, they under-served us half our dosage. So a new quest had been unlocked: to retrieve our fair share today or raise havoc!

At the lab i had no idea what happened during the morning since i slept until very late, but right after lunch everyone scattered off to handle different things:
- Sérgio and Francesco still busy documenting their ants project.
- Tara with the plastic PCB experiments.
- Jorge putting the finishing touches on his VJ mixer frame.
- Mónica pushing her wind/fan project into a first protoype.
- I pushed the genhaiku abit closer to version 2.0
- Luis arrived to the residency to work on his meal tracking idea.
- Ricardo and Filipe went on a magic journey to the local “sawmill” store to get the last parts for their piano cocktail.
- Mauricio gave us a workshop about tiny solar robots with BEAM circuits.
- And Catarina hacking some keyboard interfaces

So for dinner we went to reclaim our lost dosage of Mistos de Porco Preto and managed to succeed in our ordeal! Quest complete! We also took the wonderful opportunity to shop some essential refreshments for tomorrows farewell party.

Back at the residency we had visitors from a local juvenile theater group, we gave them a quick tour round up of all the stuff we have lying around and the projects people have been working in. Which went pretty well, they were all pretty marveled and excited with all we had going on, asking how they could do their own and spend the rest of their lives doing what we do. Which made us happy.

The rest of the night was spent attending Mauricio’s workshop and working on some entry for our fast music remix compo of Vitor Espadinha’s “Relembrar é Viver”. Results should be available tomorrow.

AZ Residency Day 4 – Routine Strike

Today we haven’t done anything at all. Nah, just kidding. We seem to have grown well adjusted to our new home, the days are almost routine and the nights grown more social, everyone seems to be so tired that work on projects after dinner doesn’t quite work out as imagined.

New ideas for projects still pop up every other second but we’re now slowly starting to focus more on specifics. Pedro seems to be nearly done with the OSCBus link to Pachube. And Francesco seems to be polishing up his ants project some more, atleast it was rumoured that we can already get some inputs from both the fish and the ants for our promised audio mischief sessions. We haven’t quite managed to have some of those yet, but we definitely will. We should also probably connect it to AssaultCube, just to reuse late night gaming pwnage from our gamer residents.

Sérgio managed to get the hall lights also synced up to OSC so it’s now clear that complete and total world domination is eminent.

Filipe has been busy with his secret new projects and also pet-sitting his fishies, who seem not to be doing so great, probably new water tank related, so they’re getting a new one tomorrow!

Jorge been busy all day building a frame for his VJ mixer, it’s looking good by now, just wish my brain could already be able to filter the dremel sound by now!

Catarina and Tiago tried to assemble a new breed of TV-B-Gone’s, but seem to have failed miserably so far. Hopefully tomorrow they’ll succeed in a little more than just finding all the possible ways that it won’t work and we’ll have something more to show and tell to the world.

The bioplastic sample tests have been somewhat neglected but we promise we’ll report something back about them. Guilherme has returned to the residency and seems to be working on some evil plans for world domination for his robots, we hope to have some follow up info on that in the next few days aswell.

Meanwhile Tara has been pushing forward her plastic bag fabric PCB ideas with a few speaker circuit tests.

All in all it seems that the daily project meetings have settled down to lunch hour. Which fluctuates. And excursions to the random local shops are now common atleast twice a day. This carefully devised and heavily pondered time management scheme is easily enabling us with the latest cutting edge technology, which allows us to put together something as exquisite, brilliant, innovative, revolutionary and so righteously dedicated such as this:

AZ Residency Day 3 – Ideas Are Like Rabbits On Spring

The breakfast table side projects meeting seems to have jetlagged slightly to lunch hour. Cold water morning shower is truly revitalizing but i wouldn’t want an encore tomorow! Despite the early shock some folks clearly fueled with their sleep deprivation managed to come up with a few other project ideas to add to our pool. Among which we seem to have a top secret facebook junkies clothing line and a not that top secret Boris Vian piano cocktail idea revamp, for the drunkards in us all to rejoyce aplenty about (related electro valve experiment documentary picture below).

So an excursion to the local city store was in order, visiting random local Chinese stores, hardware stores, textiles store, pet stores, electronic materials stores.
BTW, you should know that using a multimeter to pick a zipper at a textiles store might get you kicked out!

misc purchases

Also, musical christmas cards + cheap earplugs + silicone + skills = contact mics + hydro mics + led + cute paper leftovers for our collage club! Be afraid!

Meanwhile, in a land far far away, Tara has been very busy ironing a few random plastic bags to create a DIY PCB prototype and successfully unravelling many distinct ways on how it will defnitely not possibly work! Plus discovering an advanced paper printing technique. Follow up should come within the next few days. We hope.

misc purchases

Tiago Serra and Jorge Ribeiro from xDA have also arrived tonight, so our dinner plans also involved a little brainstorming on all of these ideas and more top secret ones TBA. Meanwhile here is another random silly photo:

AZ Residency Day 2 – Nothing Like The Fresh Smell of Vinegar Early In The Morning

Day started with a small queue to access the showers and a breakfast table side projects meeting.

Today’s plan for world domination involved:
- Connecting OSCulattor with Pachube
- Tracking fish in the fish tank
- Cooking bioplastic sample experiments
- Twitter bot with processing and/or javascript
- Taking apart old keyboards
- Planning a realtime videowall for AZ Labs

Most of the goals were reached despite the usual setbacks.

Bioplastic is sick. It’s basically starch, water, glycerine and vinegar stired together and heated slowly to a pasty bubbly form that takes a day to strengthen up. Today we cooked a few variations of the standard recipe to make a few sample experiments with different ingredient ratio, cooking time and thickness, to compare the properties and possibly maybe probably figure out some interesting use for them in future projects. They take about a day to cure, so we have no conclusions just yet, but we’re all pretty sick of the smell of vinegar by now! Stay tuned for the follow up, coming to an hackerspace blog near you soon.

Fish are nice. We like fish. Filipe brought some with him and seems to be planning some cute tracking system installation. A crack in the main experiments tank hold him back a few hours while the silicone patch dried up, so it isn’t quite operational just yet, but we’re already working hard on the next evil step for world domination: devising a clever way to centralize and reuse his little fishies tracking values. And share them with the world while we’re at it. Who knows who might need a bowl fish tracking stream of values out there.

We took a little walk wandering about Montemor-o-Novo, quite a peaceful town as it turns out, we managed to find an open restaurant with some excellent traditional Portuguese food, which was nice. Meanwhile, back in the new tech world, our plans for tonight’s generic audio mischief jam got held back by the lack of a mix table, some lag with ninjam wireless and an allnighter live broadcast stream pumping out of Autechre’s website.

AZ Residency Day 1 – We Have Arrived!

After many months of planning and plotting and conjuring evil dark forces with a few selective friendly contacts of the Audiência Zero collective, the day finally arrived where we head out for 1 week residency with members form all of our three hacklabs: LCD from Porto, AltLab form Lisbon and our very own xDA from Coimbra.

I managed to setup a ride with a couple of the big bosses from LCD, mister Ricardo Lobo and Pedro Angelo. I waited for them the entire morning, still slightly recovering from Saturdays photo exhibit opening at Galeria Icon (where xDA colaborated with Sue doing some dj’ing and projection mapping). Phonecall revealed they were already running late and suffering a major setback, a forgotten wallet, forcing them to go back to Porto.

Long story short: The northern comitive arrived a few hours later than scheduled to our destiny: Convento da Saudação, Montemor-o-Novo.

People from the other labs were already moving around working on some of their own projects: Mónica greeted us outside where she was testing the wifi access distance for her tree project. And inside we unraveled the AZ room where Guilherme was botching latest robotic creature and Catarina greeted us with a handshake using her latest speedproject, a glove with a led that lights when you shake hands. Filipe was setting up his fish tracking system in a corner. Mauricio, Sérgio and Tara were also around doing their own thing and others are scheduled to show up through the rest of the week.

Quick tour of the location revealed it to be pretty cool. A rehabilitated convent inside a typical Portuguese castle with an overview of the entire city. Plans for sightseeing abit aren’t entirely out of the question but we are mostly all really eager to get down and dirty with the technology.

convento

Sitting down we finally start to assimilate all the potential: We have a Makerbot table for 3d printing. A microwave oven, some starch, vinegar and glycerine to do some secret bio stuff (not breakfast pancakes). Toolboxes, components and PCBs for electronics fun and non profit. Plenty of project ideas involving data visualization, and fabric interfaces. And a very evil plan for collaborative sound synthesis that will hopefully involve the PA, some contact mics, random MIDI/OSC values from the running projects and plenty of laptops.

We can already present the first project, the White LED Red Glove quick project by Catarina and Isabel. Which it’ll be easier to describe by quoting her own description.

glove

This mitten lights up when its wearer shakes hands with someone. It has two exposed soft contacts around the thumb and across the palm which, when bridged by bare skin, turn on the LED embedded on the flower. The mitten itself was created by fashion designer Isabel Tomás, and we then sewed a touch switch circuit onto it using conductive fabric and thread. Isabel and I designed this as a soft circuits exercise for some upcoming materials workshops, and will post some instructions soon.

Sprint Project: RC Micro Machines

Depois do primeiro Sprint dos Laboratórios AZ, estavamos todos bastante interessados na ideia de repetir a experiência. Por isso lançamos o repto à mesma equipa e juntamos o Dino Magri do MuSA, o Tiago Serra do xDA e eu e o Ricardo Lobo do LCD. Durante o fim de semana também tivemos a contribuição do José Costa, Rui Pereira e João Ricardo que apareceram pelo LCD para nos dar uma mão a documentar o projecto e a construir a pista.

Mas que pista? Bem, havia uma ideia que tinha ficado na gaveta desde o Encontro AZ de Dezembro passado que nos estava a picar a curiosidade e inspirados pela experiência do Global Game Jam lançamo-nos ao desafio de contruir uma versão real e jogável do clássico Micro Machines. O plano à partida, era bastante simples: comprar carros RC baratos num bazar chinês, modificá-los para podermos controlá-los através do Arduino com volantes físicos e depois colocá-los numa pista real filmada por cima para dar a perspectiva do jogo original aos jogadores.

O primeiro passo foi desmontar os carros RC e os respectivos comandos para analisar o circuito e ver onde podiamos injectar o controlo via Arduino. O sistema era bastante simples e foi suficiente substituir os interruptores por transístores nos circuitos usados no comando para enviar comandos de direcção. O problema seguinte foi um desafio mais interessante, pois ambos os carros usavam a mesma frequência de rádio para controlo, o que fazia com que um comando controlasse ambos os carros ao mesmo tempo. A solução foi descobrir como a frequência de rádio era gerada e modificar esse circuito oscilador num dos carros e no respectivo comando, no nosso caso um processo semelhante a afinar um instrumento musical através de um pequeno parafuso num indutor.

Entretanto fomos buscar os controlos físicos para o jogo, uns volantes de GameCube com pedais que estavam na nossa arrecadação à espera de um projecto que precisasse deles. O facto de não serem periféricos standard colocou-nos um desafio adicional, que felizmente já tinha sido resolvido pela comunidade do Arduino, deixando-nos apenas o trabalho de adaptar o código existente para suportar dois volantes em simultâneo e incluir o controlo dos carros RC.

Com o processo de adaptação do código a todo o vapor, o resto da equipa dividiu-se para atacar os dois problemas seguintes: a montagem da pista e do circuito de controlo.

A pista foi desenhada para ter uma aparência tridimensional quando vista de cima, por isso a nossa equipa lançou-se à oficina e aos materiais disponíveis e criou uma ponte, um túnel e duas curvas elevadas para adicionar às ferramentas que serviriam de obstáculo aos carros.

O circuito de controlo deveria incluir da forma mais compacta possível a placa Arduino usada como controlo, o circuito de controlo dos carros RC e as fichas dos volantes. Na ausência de um método rápido e fiável de criar PCBs, razão pela qual devemos voltar à nossa CNC em breve, recorremos a placas de prototipagem, um suporte em madeira, cabo unifilar, cola quente e algumas soldas estratégicas para criar o nosso circuito de controlo.

O ultimo desafio foi criar um suporte para a câmara que permitisse colocá-la a uma altura suficiente para captar a pista toda. O tecto da sala onde montamos o projecto é muito alto por isso tivemos que recuperar algum material que estava na oficina para criar um suporte improvisado que permitisse aproveitar a altura de uma escadaria do edifício.

Ainda tivemos tempo para fazer algumas experiências com marcadores fiduciais e software de visão por computador com o objectivo de adicionar alguns gráficos e efeitos especiais à imagem projectada para os jogadores, mas a altura da câmara não lhe permitia uma resolução suficiente para reconhecer os marcadores, por isso decidimos deixar a exploração dessa componente para uma outra altura.

Por fim chegou a altura de juntar tudo e fazer a demonstração dos resultados do Sprint:

O código e a documentação do projecto estão disponíveis no wiki do Sprint.

As fotografias do evento foram tiradas pelo Tiago Serra, Dino Magri e pela equipa da AZ.

A pista vai ficar montada ainda durante uns tempos enquanto exploramos algumas ideias que nos ficaram desta maratona, por isso estão todos convidados a passar pelo LCD um dia destes e dar uma volta no RC Micro Machines, ou ainda melhor, juntarem-se ao projecto.
