interactivos 16 conclusions

after loosing a flyght in São Paulo I’m back home now and it’s time to make a balance.
this idea os taking out the water of urine and grey waters makes sense and with the prototype we have made in serrinha we are some steps closer. its clear that the composter is a good source of heat and specially during the night where the delta of temperature gets really big. one design flaw of our prototype has placing the boiler outside the composter. we did this to keep an eye on the boiler but also was easy to build it outside the composter. making it inside would be like making a ship inside of a bottle :p but this meant that after the hot liquid enters the boiler is starts to cold and the efficiency of the model gets compromised.. we where able of distill around 50ml during one night. we still have some problems to solve but we are on a good path to help solving urban farms biggest problem: a local source of water and nutrients.

interactivos 16 dia 13

Penúltimo dia!!! Hoje foi dia de apresentação dos projetos desenvolvidos durante o interactivos 16. As apresentações foram entre os próprios participantes, amanhã é dia da apresentação para a comunidade da Serrinha do Alambari.

interactivos 16 día 10

day 10. yesterday we fond that we need to raise a couple of meters the column.. we need 11m from the condenser to the ground so today we’ll be all day in this.





we reduced the condenser, we went from 6 to 4 pipes the aluminum pipes and we got 1m extra :)

we also started measuring the composter temperature with a regular house thermometer. tomorrow sara will give us a hand on installing one sht21 on the composter and a sht15 near the condenser .




we finish the day making connections and drawing diagrams :)


interactivos 16 día 8

Colocamos la primera capa de residuos en la compostera y luego una capa de hojas secas.

Revisando las llave que sale del bambú nos damos cuenta que está entrando aire, al parecer por la unión entre la parte roscada de la llave y el accesorio, se colocará más teflón y silicona para estas uniones.

Colocamos la madera de base donde va ir la compostera y los bambús con mangueras; la nivelamos colocando piedras y greda. Cuando esta base se aseguró levantamos el bambú con la manguera a los 10 mts, y acomodamos  las  varas en la base con la compostera.

Colocamos una  manguera en desnivel asegurándonos que este a más de 10 metros y llenamos la columna de agua para hacer vacío, al final de la manguera  colocamos un bambú con agua para evitar que entre aire.



interactivos 16 día 5

Toda la mañana revisamos nuevamente el funcionamiento de LED, logramos simplificar un poco y escribir paso a paso el procedimiento para hacer funcionar el sistema, por medio de una tabla que indica las llaves abiertas y cerradas en cada paso


A la tarde documentamos el trabajo que hemos hecho hasta ahora y retomamos el trabajo de hacer la compostera.

interactivos 16 dia 4


we started the day with a walk. is shining today and we’ll go with wha-young and her group to find the spring of the river.

img_9406 img_9420

we collected samples and measure the river flow.

img_9431 img_9437

around 11h we came back to continue working on our project. there are some parts that are not completed designed. here is angelica thinking about the container of liquids that we’ll use inside of the composter.


before lunch we received the visit of professor Caren and her chemistry students. we talked about the projects and they will collaborate with us on making liquids analysis on the input and output of the system. after lunch we made a group meeting about the daily live in the house :p


on the afternoon we started building the inside structure of the composter. we are gonna use the heat generated inside to bring the liquids that we need to boil to a higher temperature.



this is our first approach.. looks good but we still didn’t find a easy way to hold all the bambu pieces together.. any idea?


interactivos 16 dia 3

Cortamos 5 pedaços de mangueiras para fazer o condensador. As mangueiras serão encaixadas nos tubos de alumínio (6 tubos) que unidos formam o condensador.condensador

Fizemos a medição e marcação de 10 metros no bambu, os 10 metros correspondem ao tamanho da mangueira requerido para o funcionamento do sistema LED. O bambu irá comportar a mangueira.10m

O bambu foi cortado lateralmente, retirando uma tampa para o encaixe da mangueira no seu interior. A finalidade do bambu é manter a temperatura dentro da mangueira.corte1corte3



Depois de cortada a lateral do bambu, a mangueira foi instalada no seu interior.



A cinta, que será presa em uma palmeira, servirá de apoio para a roldana que utilizaremos para auxiliar no içamento do bambu. Ela foi erguida, graças ao Júnior, morador local da Serrinha do Alambari. A cinta foi colocada a cerca de 12 m de altura.subida1subida-2

O bambu foi erguido junto a palmeira.subida1


interactivos 16 día 2

Para conservar mejor el calor en la manguera por donde asciende el líquido, hemos pensado en colocarla dentro del bambú.

img_5096 img_5133

Tomamos las medidas de los bambús cortados ayer, tienen 7,5 mt.  Levantamos uno  justo al lado de una  palmera para saber si se conseguiría la altura en esa palmera.

Con cintas se ató a la palmera una cuerda con una polea, debemos subirla a 10 mts de altura para usarla en el izaje del bambú con la manguera y el condensador.


Cada uno tomo unas varas de madera para empezar a subir la cinta en la palmera, logramos subirla aproximadamente 4 mts, luego intentamos seguir elevándola con los bambús pero resultaron muy pesados para manipularlos. Cortamos el bambú más delgado por la mitad para que fuera amas fácil de manipular pero se volvieron muy flexibles y no sirvieron. También intentamos tirar un mosquetón por encima para enganchar y halar la cinta atada a la palmera pero se no se logró llegar a esa altura.

Pesamos también en ganar la atura en forma diagonal pero no sería óptimos distancias muy largas. Finalmente Sara contactara alguien que sabe escalar palmeras y pueda subir la cinta a los 10mt. Así finalizo la mañana.

En la tarde pensamos en la estructura del condensador, teniendo en cuenta colocar los tubos metálicos en diagonal para que el agua baje.

Al final de la tarde fuimos a buscar otras dos varas de bambú, y conseguimos cortar las varas de 10 mts.

interactivos 16 day 1


the usual thing for a first day: personal and work presentations.

there are great projects here! check the interactivos website to learn more about them. we had lunch together and after that we went to see our materials and where we are installing the device. after a visual análisis of the geography we have determined that we’ll use a palm tree to elevate our condenser, install the composter on the house level and use the slope that goes to the river to extend the second vacuum column that has at the end the clean water output. elevate a water column for 10m on the side of a palm tree doesn’t seems a easy task so we went to collect bambú to build a 10m tripod or some other tool to raise the condenser.

tomorrow more ;)

rio 2016

is good to be back in rio. beautiful city, sweet people, good friends and amazing landscape!! I’ll stay a couple of days errand in the city and then take a bus to Resende where I’ll meet the rest of the team and go to Serrinha in the national park of Itatiaia.

we where selected to interactivos 16!!!

we did it!! we were selected!!! we have team up with CIMNE nature on this one and made a great proposal :)

you know, this year subject of research is water and water is one of those issues on urban farming.. getting water from the grid is expensive to everyone, the ones that pay, the ones that supply it and to all of us as a planet. at the same time in urban environment we trash a lot of water, in all colors: black, brown, grey and yellow. just by the colors you can figure their content :p but the content that gives color is just a small part of it. in all around 99% is water. on the other and we need nutrients and we are all the time trowing them out of the sink. so on this project we will focus on cleaning water and reduce nutrients to a more concentrated solution that we can apply later on the farm.

this is not nothing new of course, the plants use exactly the same technic  to pump nutrients over their body.

we’ll keep you updated on the building process;)

interactivos 16


you may have notice that we are huge fans of the interactivos program from medialabmadrid ehhehehe. I’ve enjoyed a lot the past one’s and today the calls are open again. this is not a normal interactivos, this one is in rio de janeiro:) run by the amazing nuvem team, surrounded by nature and having water and autonomy has a line of work, I think we are gonna propose something :p

Scraps-grown fruits n’ vegetables

I’ve recently came across again a habit i neglected for a while. Given its role as a good alternative to composting, besides relatively quick reap, growing food scraps can be fairly inexpensive, ludic and also prevents landfill saturation. There are lots of ordinary edibles we frequently buy that would easily grow on a sunny window sill, mostly, in water, pebbles or soil, as stated here. In order to accomplish that, you might want to know that starting food scraps out in water is often a helpful way to jumpstart a plant, until it establish itself and may be able to be transferred to some other substrate.

Here you go, nearly 1-2 days after i’ve cut this leek section, i would spot it growing again. :)


And voilà:


You would not need more than this that you see on the pic. Juste make sure you keep roots in contact with the water, and nature will do the rest. Five days later i already had a small sprout popping out; you can also see at the background a sprout of avocado (i’ve cut a section so you could see it from a better angle) i had previously caught in a Rio forest . As i stated, there are severall ones you could play along with, as ginger, green onions, lemon grass, potatoes, garlic, and so on.

You must want to notice that in order to grow organic, non-GMO vegetables at home, you will need to start with organic produces.

Good luck reducing your grocery bill ;)

Ceramic pots irrigation

A very nice and didatic video about this very ancient irrigation method that uses ceramic pots (ollas).

It works with the same principle as the UFRRJ system, that uses ceramic filters as humidity sensors. The irrigation is controlled by the water saturation in the soil.

Making a home composter with worms

I will share here a low cost solution for the recycling of organic waste, appropriate for apartments and urban housing that do not have a piece of land or an outdoor area. This construction is inspired by the Cadico earthworms nice project. The photos are from the composter I made here at home  : )  It’s called a Vermi composter because we use worms in the process, uhuuuuu big thanks to the worms, they deserve!

To make this kind of composter, it is important to use stackable supports to separate the different stages of composting.

In this case, I used 3 buckets of margarine 15L reused. You can ask for them for free at local businesses such as coffee shops, bakeries, juice houses, etc.. They are stackable and perfect for the job!


The first step is to cut the center of the lids that stands between the buckets. Leave a border so that a bucket can stay on top of the other (this red lid is perfect for this because it comes with a delineated border):





Then we will make holes into the bottom of the 2 buckets that will stay on top and receive the organic waste. These holes are to drain the leachate to be stored in the first bucket underneath (this one has no holes).
You can use 4 mm drills (suficient for the worms to pass through).



Then, we use thinner drills, size 1, or 1.5 mm for making holes in the top of these 2 buckets to allow the entry of air, very important component of a good composting. (If these holes are too big, the worms will pass and it will atract some other insects in your kitchen).



We also make small holes in the lid that will stay on top and was not cut:


Now the suggestion is to make a very beautiful painting in the buckets to forget all that margarine past and decorate your kitchen!  : D

I made some stencils with masking tape, very easy to do :








Now that we have our buckets beaultiful and prepared, we can start composting! uhuuuu

We’ll start with only 2 buckets, the third one will be awaiting.
So, let’s prepare the one on top to receive our organic waste.

Place a first layer of compound or forest land. This land is rich in bacteria that will help in the decomposition process:


Now we can put our organic waste and always cover it with dry matter:


Over time, the compound begins to seem a dark mass:

When the bucket is already filled with this dark, pre composted mass, we put our dear worms! (if they enter at the beginning they might die with the heat generated)


We use the California red worms. You can ask some for someone who already has a worm farm and soon they will reproduce and increase in number. You can also buy them from a producer or even through the internet.

Earthworms accelerate much the decomposition process because they can eat daily the equivalent of its own weight (!) Besides enriching the compound with their droppings, called humus.

When the upper bucket is full…


it will be time to enter the third bucket on top of the stack! So, first, we put the other lid with a hole in the middle:


And then we put the third bucket, leaving the system as follows:


Now, the top bucket will receive the organic waste generated by the house. Meanwhile the central bucket, full of waste, will be resting while the worms do their work.

After eating and making compost, the worms will look for new food and then go up to the top bucket, we hope so. (or you can give then a hand!)

When the top bucket is full of waste, the compost in the central bucket must be probably ready, or almost, and can wait in other recipient. Then the top bucket goes to the middle and the middle bucket will be free to start a new cycle on top!

Meanwhile, the first bucket underneath will be storing all the leachate from the system:


This dark liquid is full of nutrients good to get back in the soil, but also very strong… So we can dilute it in 10 parts of water to have a nice biofertilizer! : )

And there you go!

#Some important things:

. The process of composting requires air and humidity (around 50% humidity)

. Try chopping food residues to facilitate decomposition.

. There is an Carbon x Nitrogen ratio to be maintained (initially 30:1). In practice, always cover the food waste with a good amount of dry matter such as straw, sawdust or leaves.

. The composting process generates heat, reaching between 60 and 80 degrees Celsius (!). Which is good because it helps kill the pathogens. When the temperature drops, this indicates that the compound is stabilized.

. What CAN go :::
– Fruits, vegetables, grains and seeds;
– Tea bags and coffee grounds (with filter).
– Leftover cooked or spoiled food (no exaggeration) and eggshells.
– Straw, dried leaves, wood shavings, sticks, garden pruning.
– Paper towels, paper napkins, bread paper, cardboard, newspaper.

. What MUST NOT enter :::
– Meat of any kind;
– Dairy products, oils, fats;
– Feces of domestic animals and used toilet paper.
– Excess of citric fruits (orange, lemon, pineapple, etc.);
– Excessive salt (leftovers), garlic and onion.

Composteira Caseira

(will publish this in english as a new post)

Vou compartilhar aqui uma solução de baixo custo para a reciclagem do lixo orgânico, apropriada para apartamentos e habitações urbanas que não contam com um pedaço de terra ou área externa. As fotos são da composteira que fiz aqui em casa  : )  Vermicompostagem (com minhocas!)

000_0005Para fazer essa composteira é importante utilizar suportes empilháveis para separar os diferentes estágios da compostagem.

Neste caso, utilizei baldes de margarina de 15L reaproveitados. Você pode pedi-los de graça em comércios locais como lanchonetes, padarias, casas de suco, etc. São empilháveis e perfeitos para o trabalho!
O primeiro passo é cortar o centro da tampa que ficará entre os dois baldes. Deixe uma borda para que um balde possa encaixar em cima do outro (essa tampa vermelha é perfeita para isso pois já vem com a borda delineada) :

100_2776   100_2777 100_2780 100_2781

Então faremos pequenos furos no fundo do balde que ficará por cima. Estes furos são para drenar o chorume que será armazenado no balde debaixo. Utilizei brocas de aço rápido tamanho 4.

100_2783 100_2784100_2787Usamos brocas mais finas, tamanho 1 ou 1,5 para fazer furos na parte de cima do balde que receberá resíduos orgânicos. Estes furos são para permitir a entrada de ar.

Agora a sugestão é fazer uma pintura bem bonita nos baldes para tirar todo aquele passado de margarina e fazer com que enfeitem a sua cozinha!

Como fiz essa composteira durante o carnaval, escolhi o dourado para evocar o calor do egito para dentro da composteira! (sim, ela vai esquentar muito!)

100_2793O balde de cima ganhou um stencil em espiral com fita crepe, bem fácil de fazer:

100_2792  100_2803
Agora vamos preparar o balde de cima para receber o nosso lixo orgânico.

Coloque uma camada de matéria seca, nesse caso usei folhas, e depois uma camada de composto ou terra de floresta. Essa terra é rica em bactérias que ajudarão no processo de decomposição :

100_2814 100_2817

Agora podemos colocar o nosso lixo orgânico!



Algumas coisas importantes:

. O processo da compostagem precisa de ar e humidade (em torno de 50%)

. Procure picar os restos de alimentos para facilitar a decomposição.

. Existe uma relação Carbono x Nitrogênio a ser mantida (inicialmente 30:1). Na prática, procure sempre cobrir BEM os restos de alimentos com matéria seca como palha, serragem e folhas.

. O processo de compostagem gera calor, podendo chegar entre 60 e 80 graus (!). O que é bom pois ajuda a matar os patógenos. Quando a temperatura cai, é sinal de que o composto está estabilizado.


. O que PODE entrar :::

– Frutas, legumes, verduras, grãos e sementes;
– Saquinhos de chá, erva de chimarrão e borra de café (com filtro).
– Sobras de alimentos cozidos ou estragados (sem exageros) e cascas de ovos.
– Palhas, folhas secas, serragem, gravetos, podas de jardim.
– Papel toalha, guardanapos de papel, papel de pão, papelão, jornal.


. O que NÃO DEVE entrar :::

– Carnes de qualquer espécie;
– Laticínios, óleos, gorduras;
– Fezes de animais domésticos e papel higiênico usado.
– Excesso de frutas cítricas (laranja, limão, abacaxi, etc);
– Excesso de sal (sobras de comida), alho e cebola.


Com o tempo, o composto começar a parecer uma massa escura:


Quando o balde já estiver cheio com essa massa escura pré compostada, podemos colocar nossas queridas minhocas! (se elas entram no início podem morrer com o calor gerado)

100_2825Utilizamos as minhocas vermelhas da califórnia. Você pode pedir algumas minhocas para alguém que já tenha um minhocário e em pouco tempo elas irão se reproduzir e aumentar em quantidade. As minhas minhocas vieram do TEAR onde eu e Hernani demos uma oficina de irrigação no ano passado. É um bom lugar de referência no Rio de Janeiro.

Você também pode comprá-las de um produtor ou até pela internet(!).

As minhocas aceleram em muito o processo de decomposição pois são capazes de comer diariamente uma quantidade equivalente ao seu próprio peso (!) além de enriquecer o composto com seus excrementos, o famoso húmus de minhoca.

Quando o Balde de cima encher…


É hora de introduzirmos um terceiro balde no topo do sistema!

Começamos novamente furando o fundo dele:



Fazemos furos laterais na parte superior para a entrada de ar:


E cortamos a nova tampa para ficar no meio entre o segundo e terceiro balde. Corte um círculo deixando no meio, deixando uma borda grossa o suficiente para sustentar o terceiro balde (lembre que vi estar pesado, cheio de composto).



Agora, outra pintura para encantar : )






deixando o sistema assim:


O balde de cima vai, então, receber os novos resíduos gerados pela casa.



O Balde do meio, que está cheio, ficará agora descansando enquanto as minhocas fazem o seu trabalho.

Quando o balde de cima também estiver cheio, o balde do meio já deverá estar com o composto estabilizado ou perto disso, passe então composto mais velho para um outro recipiente e ponha o balde vazio no topo para começar um novo ciclo de compostagem!

Introduction ::: Olá!

Olá hortelões!
I’m Surian, from Rio de Janeiro.
It’s been 5 months since I met Hernani here in Rio and started contributing to the Refarm project!

Last year I had many experiences with automatic irrigation using the method of professor Médici, who helped me a lot by email along with hernani. I also became very passionate about composting. Love making soil!

Now, I finally had the time to write here in this blog and so be able to share my processes with this international family of gardeners : )
It’s really amusing to read you all!

Contact ::: surian at
::::::::::::::::::::::::::::::::::: AO BRASIL  :::::::::::::::::::::::::::::::::::


Sou Surian do Rio de Janeiro e este aqui é o meu primeiro post no blog do Refarm the City : )

No ano passado comecei a pesquisar sistemas autônomos de irrigação para hortas e comecei a usar o lindo sistema desenvolvido pelo Prof. Leonardo Médici da UFRRJ que me ajudou bastante por email.

Eu já conhecia o site do Refarm, que tinha uma wiki incrível, e entrei em contato com o Hernani para trocar mais idéias sobre isso tudo aqui. Aí nos conhecemos no meio do ano aqui no Rio, demos umas oficinas juntos e vim parar nesse Blog!

A idéia aqui é compartilhar os processos de pesquisa que tenham a ver com a proposta do projeto como hortas, agricultura urbana e ferramentas de código aberto voltadas para isso tudo.

Como o Refarm (Refazenda!) é um projeto internacional, talvez acabe escrevendo em inglês por aqui para compartilhar com mais gente, mas se você se interessou ou tem alguma dúvida sobre essa história toda, fique a vontade para me escrever em surian arrouba porquê é ótimo falar sobre tudo isso ; )

Abraços e hortas!

El Nagual

*** em português ao final ***
2013 was a year of many visits to gardens and other great places where I could meet nice people, prepare some workshops, present the Refarm project and assemble some irrigation systems.
I’ll start posting the memory of these meetings here at the site to document some of the refarm
adventures in Brazil  : )

In October, by invitation of leandro, who made a Refarm workshop with Hernani and me, I went to the El Nagual Biological reserve, located near Rio, where I was kindly received by Eraldo and a lovely group of volunteers who were doing work there, like the Low Constructors Descalzos, the Three House Community and many other good people.

The El Nagual is a familiar place, which carries much of the spirit from the Refarm project, bringing people together, food production, appropriate technology and good meals! : D

The garden there is beautiful, productive and organized !
During my brief residence, we opened new beds and did a workshop where we installed an automatic drip irrigation system in some parts. Here are some photos taken by my friend Alice Alfano :::


::: Em Português :::

2013 foi um ano de muitas visitas à hortas e outros lugares legais, onde pude conhecer pessoas queridas, fazer algumas oficinas e montar uns sistemas de irrigação por aí.
Vou começar a postar a memória desses encontros para documentar aqui no site algumas aventuras pelo Brasil  : )

Em Outubro, a convite do Leandro que fez uma oficina de irrigação no TEAR comigo e Hernani, fui conhecer à reserva El Nagual, situada a 1h30 do Rio, onde fui recebido pelo gentil Eraldo e um lindo grupo de voluntários que estavam fazendo trabalhos por lá, como os Low Construtores Descalzos e a Three House Community e outras pessoas boas.

A El Nagual é um lugar familiar, que carrega muito do espírito do projeto Refarm, aproximar pessoas, produção de alimentos, tecnologias apropriadas e boas refeições! : D

A horta de lá é linda, produtiva e organizada!
Durante a minha breve residência, abrimos novos canteiros e fiz uma oficina em que instalamos o sistema de irrigação automática por gotejamento desenvolvido pelo professor Leonardo Médici em algumas partes. Seguem aqui algumas fotos do processo, tiradas pela amiga Alice Alfano.

talk with students about ocean contamination and ecodesign


today I gave a talk to the students of Visual Comunication and Design in the Federal University of Rio de Janeiro. I started with this article and then show pictures of cris jordan. them I moved to ecodesign telling my personal evolution has a designer with stories were I found trash designed by me and how I now approach to design with considerations for the environmental impacts during the lifecycle of a product. Rio de Janeiro, has all the big cities, still make today the worst examples on how our daily live cause huge damage to other species that we share the same round planet.

trash in rio de janeiro




today I when visit UFRRJ. prof Leonardo Medici was there waiting for me and we spend all day together.

instituto de agronomia

We have been in contact by email the last 6 months and today I finally could travel to Seropédica and visit all the work of Leonardo and his team. we visit “lab-farms” exchange knowledge, stories, and experiences. we talked about the refarm technologies and how they could contribute to their studies. will continue to work together so expect news soon from this partnership ;)

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..


then the breakfast

morning-breakfast morning meeting


and here a visual resume of the last days.

this is the faucet that we need to control:


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



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 ;)
