Auteur avatarTimm Wille | Dernière modification 15/05/2024 par Crina

First Prototype of a Community Repair Mobile (COREMO) Trailer designed to provide repair services by means of #ASKotec (Access to Skills and Knowledge - open tech emergency case) and other mobile makerspaces in remote areas with difficult road access. (Currently developed in Kenya)

Introduction

This step-by-step tutorial serves as an Open Source set of instructions for the prototype of a Community Repair Mobile - COREMO (Trailer Edition) intended for remote areas. COREMO Trailer will provide remote communities with access to repair services through the use of the #ASKotec (Access to Skills and Knowledge - open tech emergency case) and other mobile makerspaces/tool-kits.

COREMO is currently developed in Kenya by Adam Abdumalik with support from international makerspace community members.


COREMO Trailer serves as a first stage solution for future additional variations, modules and adaptations that will include:


- Use of Solar Power (Soldering, Charging, etc.) through the addition of solar panels

- Solar electric mobility

- Scaling production, decentralised and Open Source implementation
