project

mediaLab Prado: Laboratorio Iberoamericano de Innovación Ciudadana

This week we’ve sent off a project that we hope will be included in the MediaLab Prado “citizen innovation” workshops that will be held in late November in Veracruz, Mexico.

Our project relates to soil health in urban and peri-urban areas and how ordinary citizens around the world can learn more about their soil, its processes, what it contains, and even how to improve it using open source tools. Click the pic below to read more about the workshop.

We’ll know if we will be on our way to Mexico in the first week of September, so until then, fingers crossed as we tend to the veggie garden!

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

IMG_7554

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.

e-torneira-com-servo

and then we printed :)

e-torneira-com-servo-3Dprint-part-01

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 ;)

uau!! 2 lines that made us jump of joy :) so next september you will find us in brasil developing a electronic faucet/valve that can be made in a 3D printer. here you can see our proposal.

I’ll keep you posted on the developments here on the blog and on the wiki. please if you want to contribute feel free. the e-valve is a complex project so every help is welcome ;)

nas nuvens

http://upload.wikimedia.org/wikipedia/commons/1/16/Injector_Giffard-02.jpg

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 :)

Almacigo de lechugas

Segun la profe del curso de jardinería del Jardín Botánico, el caballito de batalla era aaalgo asi como:

Mitad perlita, mitad tierra negra esteril, y a eso agregar un poco de hummus de lombriz o turba.

Así que ahí estan los pequeño almacigos xD Uno con mezcla mágica y otro sólo con tierra negra. Las semillas de lechuga morada, mi preferida.

Todavía le estoy agarrando la mano a esto de los almácigos, pero parece que no tienen que estar al sol antes de que se empiece a desarrollar la parte aerea de la planta.. y después creo que el sol de la mañana les viene bien. Yo las tenía sin sol de la mañana y creo q no les convino nada xD

Primavera dolça

18 octubre 2011 9:51 am
La Primavera dolça és el nom del projecte dietètico-medicinal que vull posar en marxa de cara al bon temps. Es tracta de cultivar Stèvia (Stevia rebaurdiana), una planta tropical originària de Paraguai que té propietats molt beneficioses per s’organisme: a part de tenir un fort poder edulcorant, regula els nivells de glucosa en sang , les funcions digestives, la pressió sanguínia, disminueix l’ansietat en molts casos, és diürètica i ajuda en la pèrdua de pes en persones obeses. Serveix de tractament per la diabetis tipus 2 reduint o inclús substituint el tractament amb hipoglucemiants orals.

Per tots aquests beneficis trobo que és important difondre aquesta informació i promoure el consum d’aquesta planta. Hi ha una xarxa de productors d’Stèvia que es dediquen a cultivar-la i a distribuir-la de manera gratuïta a tothom que la necessiti, de manera que la gent la pugui consumir fresca des del balcó o la finestra de casa seva. La meva intenció és formar part d’aquesta xarxa i fer-la créixer al veïnat tarragoní.

El motiu pel qual es programa per la primavera ve donat per la naturalesa de la planta, que és tropical i en les nostres latituds es comporta com una planta plurianual, s’asseca durant l’hivern i torna a brotar per primavera. Es reprodueix per esqueixos, així que per iniciar el seu cultiu només ens fa falta un parell de plantes adultes
i una mica de dedicació.

Per difondre les seves propietats i tècnica de cultiu, també esta planejat de fer un taller obert al public, en el que cada participant pugui endur-se una planteta d’Stèvia.

AC/DC

They first thing is wanted to change this time is the power supply. The ATX power supply  hack is way too much for one sensor, too loud and too expensive. Too buy a 12 v leiser  batterie that is connected to a solar pannel that recharges the batterie, is too expensive ( ding ding ding ) . So i decided to use old electrodomestic transformers.

Transformers are quite commen. Those are those black boxes that come with everything you buy that needs electricity.The work of the transformer is that is converts the 220 AC into DC and the voltages and ampers whatever is need by the consumer product.  You found them in every flewmarket in all shapes, forms and voltages and amperes.  It could be a nasty task :)

I picked up three different types all of them 12 Volt and amperes from 400 mA to 60mA and payed 2 euros each.  I took a sony which a chinch ending , a langelsbold with a handy plug ??  and a matra with a network plug.

The first one i tested was the sony.  I cut of the plug and there where just 2 wires. The measuring was 18 V. 6 Voltes more then expected( cheap multimeter proberly too ) . I workd well with the 12V waterpump from the windshield cleaner and it worked well with the electrovalve 12 V. In use or standby it gets slightly warm , which means it is not of the newest generation and that it consumes a little standby energie.

The Langenselbold didnt worked? I really dont know why. I  did a short search on google where it comes from and i found nothing. I appearas that langensbold is a town in germany.

The Mantra adapter with the network plug was i big suprise. You can power 2 pumps with on transformer. The foure wires are coloured  black, yellow, green and red and the work in pairs. The output voltage was similar between the 2 possible solutions. Grenn + yellow with 14,5 Volt and black and red with 13,6 Volt. On the  transformer is written that it powers the 11 V with 60 mA. That is significly lower then the Sony , but it worked well with the LED, pumps and electrovalve. So conlusion , just look for the voltages and it should be fine. Reuse old transformers is cheap and good and re:farm . You can power your devices easily with the wanted voltages. The current is stable and safe. With the ATX power hack i alwayes had short circuits and it was annoying to work with.  When you just work in one range of voltage a AC/DC transformer can be the choise to go for to power your selfbuild things in a clean , cheap and save way up.

 

 

summercamp at shu lea & maliks house

So after beeing occupied with a lot of other things i can spent some time on the re:farm proyect. A friend and re:farm member left me her flat and to do the watering of here plants. We suggested to use that time usefull and do some humidity sensor testing. The re:farm nano board that includes the new sensor techology will be produced in november. Till that i will try to do it without to get more dates about reactive time and calibration of the system and think about electricity for teh parts.

What i found out at my place is that the reaction time of the sensor is slow and not constat. Slow is not the problem it is even more beautyfull and fits even better to plants . The are not know for beeing the hurry typ of species :)

pressure switch communication

So it definetly works!!!  My depest repect to you Mr. Medici. Your self automated watering sytem is the best low budget automated watering sytem and it beats all comercial products. 10 John Meda simplicity points for your design. I definitely fall in love with it :).

What i have seen is that it took nearly 49 houres for the plant to consume sufficent water and to overcome the hight distance between pressureswitch and ceramic sensor to do the switch.

To do the reverse operation it took nearly 50 min or to be less precise 1 hour. I handwatered the plant with about 400ml of water , directly , no dripping system. Thats the next point about this system. If it is indoor it must be precise , otherwise you water your carpet too. This will be relationated with the tubes-diameter, folds and switches inside the system, the kind of valve and pressureswitch, the waterpressure, the hight of the watertank etc.. But it is not a real problem you can addjust all this parameters with the height of the pressureswitch.

mange bien :)

Till i find out how the wiring is done for the pressure switches i decided to make a little test about the response time of the system. What i want to find out now is,  do that really works at my place with my parts and how much time my plant needs to drink the water from the switch and does it  switches. If this is done I will water the plant by hand and i will see if the process will be reversed and the switch will go back in his OFF state.

The plant is a present from a friend of us and I have no idea what typ it is, but I very happy with it and sometimes when I’m out I give here a place next to the window to enjoy the day. I watered that plant  in summer at here house and it is a very thirsty type. In a previous posting about the ceramic sensor i found out that the plant consumes about 15 ml in 24h. ( proberly, I  didn’t measured they water amount , because i dont have that equipment ).

I filled the switch and the sensor with water , and it is imposible ( with my tubes etc… ) that you dont have air in the system, but i  think that that will not be a problem. So i filled everything. The switch made click. It just takes a little amount of water, my tubes are very small, so i think the system is quite responsive.

I checked they continuity at my ports and they measuring gave me the values:

Filled = switch OFF = pin 21 + 23  =  000 /   pin 21 + 22 = 1

so during the next 24 h they continuity should change if they plant drinks the water from the switch.( yummy )

What I forther  did was to water the plant a little around the sensor. As you can see in the foto the water passed the earth and a little stayed in the groundplate. What I have seen then is that the earth absorbed that water during one hour into the system and that made the bubbles in the tube move down( 2 cm) . So it looks like that he system is really good responsive :). One point more , the switch is 40 cm under the flower pot, that is importend , because the system and the pressure relates to the difference in height from the sensor to the switch.

The LEDs are on the wall

Greetings!  I’m happy to make my introduction here on the Re:Farm blog.  My name is Andrew O’Malley and I’m a Canadian artist/engineer.  My main artistic interests are animated lighting installations and fixtures, and electronic music production and DJ’ing.

[ Eyebeam bio ]

These interests have brought me to NYC for the summer of 2010, where I’ve connected with Hernani’s Re:Farm project through his residency at Eyebeam.

My first objective is to create the PCB (circuit board) for the Re:Farm On The Wall module, a data visualization module using an LED display to present data away from the computer screen.

Here’s Hernani’s original sketch for displaying the soil moisture level from 6 sensors:

This design uses 7 LEDs to display the soil moisture level for each of 6 sensors (42 in all).  The design concept has been formalized as seen below:

The module still has 7 LEDs for each sensor (or farm/garden), but with the addition of LEDs between the groups (for a total of 48) to create a complete circle which can be used with other templates, such as the one below, for visualizing other data such as temperature or humidity:

Ideally, the board will also incorporate a stepper motor to drive a needle (like a speedometer) for an additional data channel.

I’m going to first concentrate on the LED display.  Since the board will make use of an ATMEGA microcontroller (Arduino) chip and an XBee radio (to receive the data), real estate on the approx. 3″ x 3″ board is already a bit tight, so I am currently researching Charlieplexing, an LED driving scheme which allows N*(N-1) LEDs to be directly driven by N pins of the microcontroller.  8 data pins from the microcontroller  can thus be used to control the 48 LEDs since Charlieplexing with 8 pins allows control of up to 8*7=56 LEDs.

At The Next HOPE conference this past weekend, Jimmie P. Rogers was demo’ing and selling his LoL (Lots of LEDs) Shields for the Arduino.  He has a great post about his work with Charlieplexing which I’m currently consulting.  Talk about serendipity!

In a way, the overlap between the needs of Hernani’s project and my own interests in lighting and internet-enabled lighting fixtures is serendipitous as well.

More soon!

el huerto del carnívoro

La teoría

El huerto del carnívoro es un huerto de especies para los amantes de la carne. Es además un huerto donde el ciclo de vida es el mismo para el contenido que para el continente. Con las especies plantadas se elabora la salsa del chimichurri, una salsa típica para condimentar carnes a la brasa. Con el recipiente que contiene las plantas durante su periodo de crecimiento, desde la semilla hasta la colecta, se hacen las brasas con las que cocinar la carne. Así celebraremos la recolección, con una barbacoa a la que invitar a nuestros amigos, nuestra particular fiesta de la cosecha. Simulando, en calidad de mini agricultores urbanos, las tradicionales fiestas relacionadas con la agricultura y la recepción de alimentos.

La mayoría de las plantas aromáticas plantadas en este huerto se pueden plantar y recolectar a lo largo de todo el año, independientemente de la estación. Así pues podemos establecer nosotros mismos nuestro calendario de colecta. Podemos sincronizarlo con un cumpleaños, un nacimiento, una boda. Pero también podemos sincronizarlo con algo más. Es posible calcular la cantidad de CO2 absorbido por las plantas para producir O2, también es posible calcular la cantidad de C02 emitido a la atmosfera por la quema de una determinada cantidad de madera. Podríamos dejar crecer las plantas durante el tiempo necesario para que absorban la cantidad de C02 que emitirán las brasas de nuestra BBQ. ¿Una barbacoa con una huella de carbono nula? Un poco más de churrasco por favor.

 

 

 

La receta

 

Como para todas las recetas del mundo, cada maestrillo con su librillo. Pongamos una de las que podrían ser:

3 cucharaditas de ajo picado fino
1/4 taza de perejil fresco picado
1 cucharadita de orégano seco

1 cucharadita de tomillo seco

1 hoja de laurel seco
1/2 de cucharadita de ají (guindilla-capsicum annum) molido

Este tipo de vegetales son los grandes aliados que nos ayudan a mantener alejados a insectos que son nocivos para nuestros preciados vegetales. Sea por sus extravagantes y penetrantes fragancias, por sus formas y colores; son la alternativa organica a la utilzacion de venenosos insecticidas comerciales.

En mi huerta voy a utilizar: albahaca, menta y un plantin de una variedad de la cual desconozco su nombre pero que, hasta que lo descubra, llamaremos “El comandante Marsof” [en honor a quienes fueron sus proveedores, Martin y Sofia]. Estas tres van a ser transplantadas a su debido tiempo.

Huerto medicinal

Desde que nació nuestro primer hijo, y sobretodo después de que empezase su primer año de guardería, hemos visto como pasaba por varios catarros, bronquitis, conjuntivitis, otitis, etc… En definitiva, contagios habituales en niños de su edad que comparten espacio con otros niños, en esta fase en la que todavía están desarrollando su sitema inmunitario. A pesar de la facilidad con la que los doctores recetan fármacos sinntéticos, a menudo con contraindicacions notables, desde el primer día hemos constatado como la aplicación de remedios tradicionales y naturales, tales como infusiones o cataplasmas, han funcionado muy bien para minimizar las molestias de estas afecciones.

Este huerto pretende cultivar varias de las plantas que más a menduo se utilizan en este tipo de remedios, y que se ajusten a las características de nuestro espacio y climatología.

Algunas candidatas para este huerto:

– Manzanilla
– Cola de caballo
– Romero
– Eufrasia
– Jazmín
– Lavanda
– Equinácea
– Verbena

refarm @ cceba BA final report

uau done, the last days have been busy.. but we are very happy with the results and with the collaboration of gobi :) this look of clean, big horizontal lines, the electronics location and the 30º angles of the wires are all gobi’s responsibility:p a great work here!!

but as every work-in-progress we faced some problems and best of all we faced some new problems:
-the watering system is complex with many moving parts.
-the connections of the bottles were hard to find a perfect solution. it can’t drop a single drop of water. but is a tremendous tool of data visualization. at a glance you can see how many 1L bottles of water your farm is consuming
-the water pumps demand to much water from the first bottle. we had to place a new one between the first and the second bottle.
-we have notice a watering difference between the first hole and the last one.. this farm has 4 meters long. we added more holes to the ending and made different sized holes but we should understand better what happens here.
-uploading the code to the boards stop to be problematic after we made a cables that shortcuts the radios sockets.
-data upload is working but is so juvenile:) we must work on the alert systems, the architecture of the data flow and the data visualization tool

this refarm is working but we assume that it will take a serious maintenance.
we hope that our recently born “refarmBA group” with the help of cceba can use this new tool has part of their medialab. you guys have a new toy in town :) we hope that you have fun and talk to everyone about it ehehhe

see you soon buenos aires and thanks again judith, all the cceba crew, agus clan, rocio, pablo, oscar, gabi, cyntia, galeria appetite, the ice cream makers:) and all the participants of the refarm workshops.

best to you all,
hernani

re:farm the city @ wanås foundation (progress)

do you know how to make a swedish artsoap? better yep, do you know what do you need to plant? here you have it :D

artsoppalast sunday was the Wanås opening and re:farm the city made some farming over there. check out our flirck account to see the other 3 farms that we’ve created and some other pictures of the amazing wanås landscape. I would like to thanks annika soderberg for the invitation of course but also for her big commitment on creating a more sustainable planet. we’ll keep posting the evolution of wanås farm and will keep one eye on the allotment plot project.

U.K.I farm

bw

black and white. this was the feeling that I had when I first saw this 4T of etrash parked on hangar.

etrashhangar

during the following week I’ve been scavenging for raw materials over this trash. the white feeling comes with the joy of having all of this etrash to get amazing parts following by a black cloud of pollution, toner powder, acid from batteries, and all sort of hazardous material all mixed and without an easy way to isolate them from being absolved from my lungs and skin. today the human body have  300X times more chemical compounds than 100 years ago. for example cadmium is widely used in industrial processes, as an anticorrosive agent, as a stabilizer in PVC products, as a colour pigment, in the fabrication of nickel-cadmium batteries also phosphate fertilizers show a big cadmium load. this human-inbody-pollution comes from the paint that we use on our houses, the cleaning products, the VOCs that most of our teckno-gadgets free every 24h of every 365 days of the year and are also present in our food.. basically in the cities we are surrounded of potential health problems and we are sharing these with all the animals and plants that also live in this planet.. and these 4T are a mirror of this. to put this things worst, nothing is designed for disassembling.. you must have 3432 different kinds of tools to take apart everything and most of it is glued forever. the artist sue lea that is having a residence at hangar is the responsible of this landscape. one day of etrash from barcelona city in front of us.

4 tones of toxic waste.. tears fall from my eyes.. this is a very dark thing to reflect on. and the nonsense part of all this is the great amount of money that the consumers paid for this trash, the great amount of expensive materials like gold, silver, aluminium, coper, plastic and totally functional motors, pumps, powers supplies, screens, rare magnets buff you name it and its all there on this 4T.

but having access to scavenging this trash had a price:) sue lea asked me to develop some futuristically plants :) on work is about UKI a post modernist fragmented replicant that lives in a world of etrashscape where love and sex are not connected. so this was the exercise: make a farm for UKI word. so I’ve proposed to sue lea 2 plants: one poisonous and one aphrodisiac :D

poison-plant-4-uki

apart from the science fiction exercise I was able to test some technical solutions that I hope to apply on re:farm. I now have a big box full of steeper motors, magnets, wires, resistors, condensators, etc.

these have been some amazing days, taking all the guts from Ibooks, powerbooks, pc towers (great power sources 220AC to 12V, 5V, 3.3V DC) hard disks, cd/dvd/flopy readers (powerfull magnets, bright round blades, steeper motors and precision mechanics) printers (motors, wells, …) more time I had more stuff I’ve found..

maltixa

It was a pleasure working with sue lea, she is good mood in person :) Tiago (from altlablx.org) was with us, nuno guerra, andreas puk, loida gil, nia silva and natércia silva all gave a great help.

first draw and project concept

SAMSUNG DIGITAL CAMERA

this is the first draw of the refarm. the initial idea was to make two systems of growing plants: one, in hydroponic and the other in the classic system with soil. the hydroponic is interesting because you can save water and barcelona is one of these cities that have huge water problems, but soon I left the idea because monitoring this system remotely it’s very expensive. So I stuck with the classical organic/substract system. In the picture you can see what I propose to control: automatic watering system, humidity measure, temperature measure and articial light all controlled by arduino. let’s see where this is going to. deadline: spring/summer 2009
