A l’automne 2020, Jose ARAUJO, doctorant de l’unit\u00e9 mixte de recherches IEES Paris, a men\u00e9 une exp\u00e9rimentation sur des vers de terre.<\/p>\n\n\n\n

Le but de cette exp\u00e9rimentation \u00e9tait de voir l’influence de leur pr\u00e9sence dans diff\u00e9rents types de sols, sur les propri\u00e9t\u00e9s physiques, biologiques et chimiques de ces sols.<\/p>\n\n\n\n

Pour cela Jose a d\u00fb mettre au point lui-m\u00eame des microcosmes, c’est-\u00e0-dire des mini-terrariums o\u00f9 il pourrait mener ses exp\u00e9riences. Pour son exp\u00e9rimentation il avait besoin d’une cinquantaine de ces microcosmes. Il est donc venu au Cofab pour mettre au point une partie de son mat\u00e9riel. Il a \u00e9galement eu besoin du fablab manager pour des conseils, la formation \u00e0 certains outils ainsi qu’un accompagnement dans la r\u00e9alisation de son projet.<\/p>\n\n\n\n

Les microcosmes en question ressemblent \u00e0 des cylindres de la taille d’une bo\u00eete \u00e0 chaussures environ. Ce sont des tron\u00e7ons de tuyau en PVC, avec un syst\u00e8me de paroi semi-perm\u00e9able au fond du cylindre. Celle-ci doit laisser passer l’eau lorsque les terrariums sont arros\u00e9s, mais ne doit pas laisser s’\u00e9chapper les lombrics. C’est cette derni\u00e8re partie qui a \u00e9t\u00e9 con\u00e7ue au fablab : ce sont des pi\u00e8ces de \u00ab\u00a0tissus\u00a0\u00bb en nylon, d\u00e9coup\u00e9es en formes de disques \u00e0 la d\u00e9coupeuse laser. Elles sont simplement tenues sur le tuyau en PVC \u00e0 l’aide d’\u00e9lastiques.<\/p>\n\n\n\n

Ce projet est int\u00e9ressant parce qu’il illustre bien le type d’utilisation des technologies low-cost que l’on peut faire au Cofab in Bondy.<\/p>\n","protected":false},"excerpt":{"rendered":"
