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

Vinicius Senger



Agenda

Introduction

Open source hardware

Hands-on automation circuits

Integration with Java & JavaFX

Complete architecture demo


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)

Vinicius Senger



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)

LED illumination

Sensors: presence, temperature, light, reed, etc.


How much it cost?

Main Board Controller

Each wall socket

Dimmer

Communication

LED illumination


Automated house architecture…


Agenda

Introduction







You can take, distribute, modify and make money

Taking back the control about what is happening in our computer

D.I.Y consumers

New and exciting market!

Very big community


Rep Rap


Monome


Segway


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;


Sun Spot

Nice and expansive: U$ 750,00

Include 2 Spots and 1 PC station board

Suppose to have different sensor boards

Squawk virtual machine

Small community


Sun Spot – mainboard(podemos tirar)

The main board includes:ARM based (AtmelAT91RM9200)

4 megabytes flash memory

Wireless 2.4GH

JVM embedded

3.7V 720maH rechargeable battery


Sun Spot – sensor board (podemos tirar)

The default sensor board includes:Accelerometer

Leds

Switch

Light Sensor

Temperature Sensor

High current driver (small DC motor)

3 X Octal Register/Driver (led matrix)


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


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


Arduino

Arduino can run Java?

NO, not the legal Java.

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


Program-ME

Brazilian development board based on Arduino

Arduino + inboard resources:

LEDs

4 high current transistors

Light sensor

Servo and analog simplified inputs


Beagle Board

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


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


Agenda

Introduction






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


Relay PCB


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


Demo #1

Introduce the central board controller

Introduce JavaFX central console

Show relay usage using Bluetooth


Digital Dimmer A/C light

More advanced circuit using optical isolator and TRIAC (solid state relay)

Can control A/C power for: Incandescent light

Shower

Fan


Demo #2

Digital dimmer in action with bluetooth and JavaFX

Futuristic dimmer


RGB Illumination

High power and low consumption;

Can be RGB or one color;

Very simple to drive:Uses three transistor PWM digital ports


Going beyond...


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


Best Wireless Architecture


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;

DEMO JavaFX code with Arduino


Conclusion

Many choices to automate your house by yourself

Open-source hardware and software make it easy and acessible

Do it yourself is a reality!

Cheap & fun!
