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.

waste or food

by traveling from city to city I find different sources of the stuff I need, different ways to get to them and big differences on how its each city manage the inputs and outputs of resources. one of the outputs that we have been very concerned here on re:farm is the organic material that a city produce and it’s mostly wasted in big cities. more than wasted, is being mixed with paper, plastics or glass making the “eventualy” recycling process even more painfully. all the organic material produced by our kitchen, restaurants, markets and their super relatives are the raw material for your first step into farming.

you need to get good soil and cheap and this is very easy and simple: our organic waste is food for worms and their waste is food for our vegetables. with this in mind we are gonna setup this new mega composter at Andes and monitor the life of the worms and friends.

the winter is coming so we don’t expect a big grow in the worms population. as everything in nature this will take time. we will follow the live of this object and also see how the materials applied evolve. I’ve design a house for worms with places for them to rest, feed and live. a hexagonal frame?! why not? inspired by nature and a link to the global ecological disaster that is happen right now in the bees superfamily and with their unique position in our live cycle. hard days for our vegetables and belies will come without the bees ;( follow the evolution of this project on this dedicated page

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);

void loop()                     // run over and over again
analog = analogRead(5);

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


analogWrite(ledPin, 0);

delay(3600000);} // waits one hour


diy refarmboxes (part1)


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.
