projects of the network

Some of the projects run by nodes or members of reGOSH

open agroecology lab

The open agroecology lab is the outcome of an ongoing dialogue between the Ayllu Coop, CEFIC (Centro de Formación e Investigación Campesina) and members of ReGOSH

This proposal aims to integrate several low cost and open source methods and instruments into a lab to accompany peasants, farmers, students and researchers in the visualization and documentation of changes produced in farms during their transition towards agroecology.

PAPATRÓNICA

The overall objective of Papatronica is to make available to small and medium-sized producers as well as to the entire potato value chain (and vegetable production in general), an open and modular open source, low-cost platform to determine the processes or specific points within a process where shocks, mechanical damage and environmental conditions affect the quality of the produce. This will significantly reduce post-harvest product losses (approximately 35% of fruit and vegetables produced).

environmental monitor

We seek to create a system to monitor air quality in areas at high risk of air pollution by developing low-cost sensor-based devices. The sensors will be calibrated using machine learning models with measurements provided by standardised particulate matter sensors.

low-cost open hardware for physics lab

The aim of this project is to develop a series of free and open, low-cost instruments to equip physics laboratories together with the necessary documentation for their replication/modification and educational resources for their use by teachers and students. Initially the project is intended for classical mechanics experiments. The project has been developed by the Mendoza node of the reGOSH network, in collaboration with members of the Ecuador and Colombia nodes.

soil respiration chamber

Development of a low-cost, portable soil respiration chamber capable of measuring the CO2 flux in soil in order to determine the soil biological activity. The aim is to analyse soil samples treated with bioinputs used by local communities promoting the transition to agroecology. This project is a development of the Mendoza node of reGOSH, funded by CYTED. The proposal is available in Spanish here.

BREWERMICRO

Microscope to monitor and count yeast for beer and fermentations in general. We aim to develop and characterize low-cost DIY microscopes that brewers can use to see, count and check yeast viability.

mini cnc

The mini-CNC project is about designing and building a mini CNC router as a hyperobject, using Arduino and repurposing unused CD/DVD reader motors. The first result was the appropriation of CNC technology, and of the free methods of development, documentation and manufacturing. The experience and details of the project can be found in their wiki.
We then replicated it in Buenos Aires and moved, at the same time, from miniCNC to midi-CNC. The documentation of the successes and journeys of this stage, which also taught us a lot, can be found here. And now we are going for more! 🙂 PS: special thanks to Renan Soares and the CTA (UFRGS, Porto Alegre) who made the project possible during reGOSH 2019.

Scientific instrumentation and physics education

The Centro de Tecnología Académica (IF/UFRGS), which is part of the Porto Alegre Node, develops open hardware and software projects for the production of scientific knowledge and also for science education.

Currently, our main project is Cosmic Pampa, a cosmic rays detector based on low-cost microcontrollers, and ERGANE, for 3D-modelling of archeologic artifacts. Other projects include SACADA, a system for data collection and analysis, Estación Meteorológica Modular, a modular system for citizen weather monitoring, João-de-Barro, a PCI milling machine, neuroestimulador, for in vitro tissue microestimulation, Cardiorespirómetro, an instrument for monitoring cardiac and respiratory signals, and the eolic microgenerator, for producing wind energy in a decentralized way. Software projects include CAE TropOS, a Linux distribution equipped with powerful free software for engineering, and ALICE open-data, for using open data from the ALICE experiment for animating physical phenomena.

gorgas tracker

GORGAS is an open source GPS tracker developed by the Health Innovation Lab at the Alexander von Humboldt Institute of Tropical Medicine. The GPS tracker was developed and used in a study to investigate the role of human population movement in the epidemiology of malaria in indigenous communities in the river networks of the Peruvian Amazon.

vuela

Vuela is developing a toolkit for doing open science with drones, accessible to marginalised communities, activists or researchers alike, and useful for studies or data surveys where this technology is already in use but dominated by closed source tools.

Team & contact

The members of our ‘crew’ are amateurs, civil society activists, researchers, neighbours, students, developers, and in the workshops we have spoken Spanish, Haitian Creole, English, French and Portuguese. Contact: Gustavo Pereyra Irujo, gpereyrairujo@gmail.com

Cyclic-Lab: Basic lab equipment with open hardware and recycled materials

Cyclic-Lab seeks to reuse and recycle different materials to manufacture basic laboratory equipment at low cost. The designs make use of digital fabrication and are freely available so that they can be customised according to the needs of each user. Among the materials we reuse are disposable plastic containers and electronic waste. Centrifuges, micromanipulators and mechanical stirring equipment have been developed. We continue to work on developing more designs.
