interactivos? 2013 resume

you know.. good things always reach a end.. this were 2 amazing weeks were we came to make one thing and finished making 4 :)

mesa trabalho interactivos13

for the ones who never printed on a 3D printer and think it seems so easy, you have no idea.. and the press have talk and talk but rarely puts the hands on a printer. ars has the most honest press cover I’ve saw. so let’s start from the beginning. we came here to make a low power faucet that could be printed. after some initial research we found many models on thingiverse that could be adapted to our needs. we give up the designs that flows water inside cause it’s impossible to have precise measures on a 3D printed object and then impossible to water seal any mechanism so we went to another approach: let’s print a mechanism that can close and open a real faucet. with this approach we could implement the watering system on virtually any faucet. we also saw that printing gears was delicate and that means we need to print big gears to compensate the small errors. in the meantime with so many starts and stops on the 3D printer other projects popped from those 20 amazing brains that eat, work, drink, laugh and slipped together for 16 days. the first that came was the mini hydraulic ram. the idea came from elflin and it’s a recurring problem in our designer’s heads: how to pump water from the bathtub to the toilet on a old bathroom? we produce many hand draws but we didn’t finished a complete 3D model only the mini water valves. magrão documented the process here on the nuvem’s wiki

one day a new 3D printer came. we didn’t had place for her so we built a table :) this was our project #3

we also debate and advanced a bit more on the electronic board “mini vacations” with thiago. in a couple of weeks we’ll send them to the press. 3 packs: one to barcelona, one to san francisco and other to rio de janeiro. surian will get the boards in rio so if you what one ask him :) surian was also involved on the next project the #5: monitoring of the composter built by joaquim. surian documented everything here.

well “galera” (bruno, chintia, julia) I think it was the best and the most immerse interactivos? that I ever have been.. I’m sure that medialab_prado is proud of you and how you worked the open model of interactivos workshops ;) congratulations!!

I will not mention my collaborators mainly because everyone collaborate with all the projects. I made new friends, laugh all the time, spend a great time surrounded with exuberant nature and brilliant humans ;)

we will continue our development on the 3D printed e-faucet and the other projects. expect more news soon.

stay happy, people in RJ can teach you that ;)

interactivos update

do no were to start :) maybe for the morning face washing on the river that flows on nuvem..

nuvem-river

then the breakfast

morning-breakfast morning meeting

outdoor-meeting

and here a visual resume of the last days.

this is the faucet that we need to control:

foto-torneira-nuvem

we have started from designing valves that can be made in 3D print

Ram-pump-valve-openscad

Ram-pump-valve-3Dprint-00

then we design a mechanism that can be adapted to the faucet. this one is moved by a servo motor.

and then we printed :)

we will continue this development for the next 9 days. you can check the wiki of nuvem for a day by day report. more news soon ;)

creio que é o primeiro post que escrevo em português :) ontem apresentámos a nossa proposta para uma residência artística na nuvem.tk a ideia era formalizar a nossa colaboração com a UFRRJ no desenvolvimento do sistema de rega de baixo custo, conhecer a nuvem e poder contribuir para um projecto que busca uma harmonia entre humanos e biosfera e obviamente hihihi poder voltar a participar num interactivos! trabalhar com gente nova e que sabe mais de “outras coisas” :) a nossa proposta é por um lado ligar o sistema de rega a uma placa de refarm para que possamos recolher dados e enviar-los aos nossos servidores e por outro lado desenvolver componentes específicos (uma torneira) de codigo aberto.

olhando para o sistema UFRRJ há 3 componentes que são difíceis de encontrar globalmente ou que diferem radicalmente de cidade em cidade. outros não :) por exemplo o presostato é um componente global. em todas as cidades que fomos sempre encontrámos máquinas de lavar a roupa donde era possível retirar o presostato e de regular os mecanismos internos para que funcione com a pressão requerida 1KPa. no caso da electro-valvula/torneira/mecanismo-de-fechar-um-circuito-de-agua não conseguimos encontrar uma fonte regular deste componente nas cidades. primeiro porque genética de refarm: como fazemos oficinas não trabalhamos com altas voltagens e as valvulas que mais encontramos são as das maquinas de lavar roupa/louça. estas são todas a 110-220V ac. a voltagem comportável para trabalhar com todas as idades é entre 3-5V dc.

segundo porque não encontramos frequentemente electro-valvulas de baixa voltagem.. há umas numas impressoras profissionais, outras numas máquinas de café, outras na nautica, mas não é um componente comum a nivel global. esta é a nossa proposta concreta para a nuvem, desenvolver uma “e-torneira” para ser reproduzida localmente com uma impressora 3D.

o outro componente intrigante é o sensor de cerâmica. este componente tem muitos desafios pela frente antes de chegar a ser um objecto que possa ser reproduzido segundo as matérias primas disponíveis nas cidades.

só 5 propostas serão aceites, cruzem dedos :)
