MAEB 20-21: Metabolic Systems: Information
==========================================
## Introduction
We spend our lives interacting with systems and interfaces whose underlying technology we hardly understand not merely due to their complexity but also because they were intended to be closed by design.
We will explore the internal components building everyday technologies and think how they can be used to create innovative building metabolisms that change the way we in habit.
Each student group will develop a prototype of an intelligent building node capable of measuring and/or actuating on the environment. Nodes will communicate remotely to create logics and report data to a central dashboard.
The module will take an experimental approach focused around tools for prototyping hardware such as Arduino, Sensors, Actuators and Raspberry Pis.
## Objectives
The objective of the module is to bring students closer to the underlying technologies building nowadays systems to enable them to think out of the box and sketch in hardware their experimental building management systems.
## Methodology
Each day will be dedicated to one topic and will be split into one or multiple introductory keynotes plus a hands-on session. During the hands-on session, each student group will develop a prototype of an intelligent building node.
Each node will have a sensor and/or an actuator and will be able to communicate remotely to other nodes. The overall system data will be visualised on a central interface. For prototyping purposes, the nodes will be scaled down versions but will need to be fully working and interacting with the real world.
Technically each node will be based around an ESP8266 microcontroller and will communicate using the MQTT protocol. A collection of sensors and actuators will be provided to pick from. A Raspberry Pi will be used as our small datacenter where logic and interfaces will be built using the Node-Red graphical environment.
## Schedule
Each day will be dedicated to one key topic:
* Information, computers and platforms
* Sensors and actuators
* Logics and protocols
* Networks and interfaces
* Building and testing

## Instructors
* **Guillem Camprodon**
* **Victor Barberan**
* **Oscar Gonzalez**
## Materials
All the electronics materials as development boards, sensors and actuators will be provided during the module. However, we encourage those already owning an Arduino Kit, a Raspberry Pi, etc. to bring it.
**Bring in your laptop and any prototyping tools you have around such as a cutter, tape, markers, screwdrivers...**
**:warning: All the provided materials will need to be returned by Friday after the module finishes**
### Books
Below is an eclectic list of books that range from technology criticism, design principles towards hand on guides on building hardware and software. We choose them because we love them.
