First construction workday at Can Roger

Can Roger_13.12.17_01Yesterday we finally broke ground in Can Roger, after months of delays and bureaucratic permits.

Olga, Pere and Hernani came down from Tarragona armed with shovels and hoes, and we started redistributing more than 10 m3 of soil that the municipality of Barcelona had left us in the lot as a (backbreaking) present.Can Roger_13.12.17_02Can Roger_13.12.17_03We used some of the soil to level the area where the first phase of the urban farm will go, and we started laying the pallets properly spaced on the ground.Can Roger_13.12.17_04Just before lunch, we received a shipment of flower bulbs plastic crates, which will become the base of our growing containers.Can Roger_13.12.17_05The urban farm in Can Roger is starting to take shape!Can Roger_13.12.17_06

kitchen farm

we need a small farm to be a demo on our workshop. andreas design this one and we built in one night hehehe we call it kitchen farm. it’s indoor and contains those plants that you like to have fresh when cook, like parsley or fresh tomatoes ;)

Diari de Circ 11-01-2012

Siguiendo con la temporada 2012 de l’HdC estuvimos Hernani y servidor trabajando en una mesa de cultivo. También vino Juan Barientos, ferviente permacultor y entusiasta en general, con el que estuvimos charlando sobre modelos de horticultura para aplicar en l’hort.
Os dejo las fotos de lo que empezamos a montar y esperamos acabar en breve:
1. Sobre unos ‘zapatos’ de plástico resistentes al agua y la humedad atornillamos unas vigas de madera resistentes al paso de un tanque.
2. Sobre estas vigas, 3 palés, de 80×120 para hacer una base total de 120×240 y espacio para un banquito/plataforma para niños.
Queda poner los listones laterales para contener tierras, colocar la lamina drenante, llenar de tierra y plantar. También está la opción de hacer una cobertura con estructura de caña y montar un pequeño invernadero y seguro que muchas más.
Abrazos,
martín.

day#3 at TASML

building farms,

building the scarecrow,

and get soil.

this soil came by the hands of michael and emi (remember the little donkey farm?) yep beijing is a huge city but as always great minds think alike :p and on my 2nd day in beijing I’ve meet emi, michael and elaine from homeshop. emi as been organizing the Beijing Farmers Market. next sunday it’s the 3rd edition, luckily I’m here :)

back to the workshop, tomorrow we start the electronics :D I’m really eager to build this board, not that they are very different from the previous versions but I’ve rearranged the position of all components and now we have a more integrated board.

I’ve added a ICSP connector so no more taking the chip to burn a new bootloader and I’ve also add a connector socket to booth boards, the on vacations and on the sofa so it could be easier to send code to the Atmega without having the xbees and last but not the least the voltage regulators and the tip120 are now flattened and not so exposed to breaking during the manipulation.

potatoes box

hi :) this is a prototype of a potato box to grow potatoes in the city.

this idea came from an invitation from derek to the eyebeam residents to participate in Farm City: Where Are You Growing? A Celebration of Urban Agriculture!

Derek Denckla, editor of thegreenest.netand founder of FarmCity.US, has curated a three weekend program series for the French Institute Alliance Francais (FI:AFCrossing the Line Festival.

Over three weekends, Farm City celebrates Urban Agriculture and explores the possibilities of a new agrarian future within the current urban reality.

for now here is some pictures from the concept to the farm. during the next months we will be adding rings with soil leading the plants to a constant reach for light and you can see here how the farm is doing by visualizing her temperature, light exposure and moisture from the 4 sensors. this farm is going to produce potatoes for the new’s year dinner :)

andes composter

with a structure inspired by nature the idea was to make a huge composter or aka the worm palace:)

build with local harvested materials and equiped with a refarm on vacations board with 4 sensors of temperature (3 inside, 1 out side) connected to the house by radio and uploading data to our servers.

this has a community build project by the refarm group ny  and all the andes sprout society has participate :) 6 days of very relaxing labor lead to this

now we just need to wire this and start to get data in the server.

the nycR re:farm group will go upstate this weekend again, we will have a worm party and , you are more than welcomed to come, just bring some food to the worms ;)

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

l’hort del cuiner or “this farm is sheeet”

this is one of our hanging farms.

"hort del cuiner"

I call it the cook’s farm. the idea is to have a selection of flavours that are used to give some sense to the food as a meal :) we’ve got  http://viagraonlinestore.org/ viagra prescriptions Parsley (Petroselinum crispum),  Chives (Allium schoenoprasum), Garlic (Allium sativum) and some space for the cooker of hangar put some plants at his choice. the second part of this post title are the words of one of the hangar’s guards. the original expression is: “esto no es un huerto esto es una chapuza!” and was his last argument on the “is this a park for a car or a place for a farm” discussion.. I’m sure we’ll soften his heart and feed his body when he taste some of the herbs or use some tomatoes on his “pa amb tomaca”. or does he eats cars?

refarm hydroponic

refarm-hydroponic

we have added some pics to our flickr account. some of them are the refarm hydroponic that we have built in interactivos09. here is the code that lalo (Eduardo Meléndez) prepared to us. enjoy and let us know what bugs did you find ;)

////////////////////////upload this code to arduino////////////////////////

int analog = 0;
int ledPin = 10;              // LED connected to digital pin 13

void setup()                    // run once, when the sketch starts
{
pinMode(ledPin, OUTPUT);      // sets the digital pin as output
pinMode(3, INPUT);
Serial.begin(9600);
}

void loop()                     // run over and over again
{
analog = analogRead(5);
Serial.println(analog);

if(analog < 7){

analogWrite(ledPin, 125);   // sets the LED on
delay(30000);                  // waits 3 seconds
analogWrite(ledPin, 0);    // sets the LED off
delay(10000);                  // waits for a second
}else{

Serial.print(“nivelALTO”);

analogWrite(ledPin, 0);

delay(3600000);} // waits one hour

}

diy refarmboxes (part1)

refarmbox

we are making some prototypes of “refarmboxes” :) the idea is to built a self watering system with low energy inputs. everything is stored: soil, nutrients, water and the plant. we will test it with some sensors of humidity to see how well does the system works. it’s a low-budget concept so you can make one for your self or give as a present;)  soon we post more detailed instructions after some tests.

ingredients:

2 barrels of 20L sunflower oil

1 sock

50cm of tube

funnel

12  pin headers and electric wire

1 arduino

refarmbox2

refarmbox1

hack a leopold

leopoldo

yep, today we have received a leopoldo at home :) when we came from madrid we went to visit pep and he offered us a leopoldo with the condition of hack it. so that’s what we’ll do! the idea have some sense let´s see why: when you open one leopoldo like the one we have, you see that is huge, 120 Liters of soil!! uau I imagine that you can have a very nice production of this baby.. so we have decided to raise the numbers of production and make a leopoldo soil free. today has born the hydro-leopoldo :)

why a semaphore?

refarm_semaphore

for one reason: is very “city”:) but for now I don’t see that this semaphore is gonna help us much.. RYG red yellow green.. I even don’t know what is the spectrograph output of this object! and 220V is really a BIG problem for 2 reasons: is a petrol expensive solution and hard to control. but let’s first know what are the needs of the plants and then we come back to this problem. and speaking about problems I still don’t know what plant I’m gonna “plant” :) lets see what comes from the meeting that I have next year with the director of the botanic garden here in barcelona, I was thinking on something to eat or something to protect. a vegetable or a endangered specie?

materials (concept)

for this city project (that meant to be low-tech and open-source on software and hardware) I will use as much as possible recycled stuff. since life without water as no meaning we start the materials post with a PET bottle of water.
