This talk...

Is not a product, solution or standard

It´s about putting accessible technologies together literally inside your house;

It’s about community and open source experiences

Globalcode – Open4education

Agenda

Introduction

Open source hardware

Hands-on automation circuits

Integration with Java & JavaFX

Complete architecture demo

Globalcode – Open4education

Introduction

Electricity and electronics in our houses:

Past I: making electricity accessible and cheap

Past II: making it smaller and faster

Past III: digitalizing and integrating everything

Past IV: saving energy and improving intelligence

NOW: making it simple and open source!

Future: making automation accessible and cheap(all around the world)

Globalcode – Open4education

Introduction

Computers Vs. People*:

Past I: one computer for many people

Past II: one computer per person

Today: many computers per person (rich person)

Tomorrow: many computersa per person (including poor people)

OSHW Controllers

Normally uses microcontroller: single integrated circuit with CPU, memory and I/O.

Low power consumption

Normally bare metal

Many options: Atmega / Arduino, BasicStamp, ARM, Netduino..

Some of then support Java, but most cases you need to write some C code;

Arduino

Famous open source hardware project created by Maximo Banzi, Ivrea University

“Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.

It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. “

Arduino

Simple board based on Atmega328 MCU

Cheap: U$ 30 – BIG community

Limited resources:16 mhz

32k flash

2k RAM

6 analolg ports

14 digital ports (6 PWM)

Default language is C / C++ using GCC AVR

Arduino

Globalcode – Open4education

So simple that you can do your own PCB

You can take out many components for production

Very easy to draw and DIY

Arduino = simple

Globalcode – Open4education

Arduino

Arduino can run Java?

NO, not the legal Java.

But YES, www.kaffe.org – not officially Java.

Globalcode – Open4education

Program-ME

Brazilian development board based on Arduino

Arduino + inboard resources:

LEDs

4 high current transistors

Light sensor

Servo and analog simplified inputs

Globalcode – Open4education

Beagle Board

Very nice board for U$ 149,00, good candidate to be the central controller

Globalcode – Open4education

Which one?

Price Good for Not good for

Sun Spot 750,00 prototyping with wireless and Java

production

Arduino 30,00 smaller dedicated controller

Medium / high process, like video

Beagle Board 149,00 medium / high process smaller controllers

Raw Atmega < U$ 10,00 production for small dedicated controller

prototyping

Controlling Relay

Very simple and useful with different applications:Wall socket

Electronic Lock

Electronic garage door

Basic circuit components:Resistor, transistor, diode, connectors

Just use 1 digital port for each relay

Globalcode – Open4education

Relay PCB

Globalcode – Open4education

void setup() { pinMode(2, OUTPUT); pinMode(3, OUTPUT);}

void loop() { digitalWrite(3, LOW); digitalWrite(2, HIGH); delay(1000); digitalWrite(2, LOW); digitalWrite(3, HIGH); delay(1000);}

Arduino Code

Going beyond...

Globalcode – Open4education

Wireless in you housePrice Resume

433 mhz U$ 15 Simple but can be hard for many transceivers in the same environment. Good to have into house components.

Bluetooth U$ 60 Very trustable, good for cell phone control

Wifi U$ 100 Large distance, is expansive to have into house components, but perfect for central controller

xBee U$ 30 The best choice, good price and many working mode

X10 >U$ 200 Best choice for AC control

Globalcode – Open4education

Best Wireless Architecture

Globalcode – Open4education

JavaFX

Our choice because:It’s simple and rich

Simple to integrate with wireless communication

Simple to integrate with Sun Spot, Arduino or any other else;

Java RXTX;
