Caution : Be Careful in Handling Mains Voltage!

Welcome

Open Source Hardware Projects Rpi, Arduino

Raspberry Pi Features

Possible Areas of Use

Remote Connecting to Raspberry Pi

Java and Raspberry Pi: Open JDK, Oracle JDK

Installing Tomcat

Installing no-ip.org Client and Internet Access

Prime Faces Application Deployed in Tomcat in Raspberry Pi

Source Code Walkthrough

Remote Deploying war file

Hardware interfacing Digital Out

Hardware interfacing Analog In

Fritzing Tool

Demo

Beagle Bone (Texas Instruments)

Korean Firm, former game platform

SOC: Sytem on a Chip

Single Board Computer Broadcom BCM2835 system on a

chip (SoC) ARM1176JZF-S 700 Mhz processor VideoCore IV GPU 512 MB RAM SD card for booting and persistent

storage. Linux Operating system Low Cost Low Power Python is the native programming

language C,Java,Perl available

Hobbies

Educational Purposes

Low Cost File/Media Server

Low Cost Web Server for small applications

Fast Prototyping (In Development Stage)

Even build a home brew supercomputer!

Check

Kickstarter.com

Make: Magazine

Maker faires

SSH

Putty and WinSCP

Without router: NO NEED for a cross-over cable. RPi LAN chip is smart enough to reconfigure itself for direct network connections.

Routerless Connection: dhcpsrv2.4

Mobile Connection: Juice SSH Android

Open JDK,Oracle JDK

Oracle JVM with ARM processor support is available

Comes in Raspberry Pi already installed

Pi4J Lib

Installing tomcat Download tomcat package and unzip it to /usr/lib/apache-tomcat-7.0.47

tar xzf apache-tomcat-7.0.28.tar.gz cd apache-tomcat-7.0.28/conf vim tomcat-users.xml

Add a user to the authorization file Tomcat-users.xml file directly below <tomcat-users> add <user username="pi" password="raspberry" roles="manager-gui"/>

Start Tomcat sudo sh startup.sh

Free Dynamic IP Adress Download no-ip client wget http://www.no-ip.com/client/linux/noip-duc-

linux.tar.gz

Run client sudo /usr/local/bin/noip2

Automatic startup Create script in /etc/init.d

Can be used from Mobile Clients,too

IoC ◦ GPIOControllerFactory

Testability ◦ Apache Commons PropertiesConfiguration

◦ Parameters.properties

◦ MockGpioController and MockGpioPinDigitalOutput

Script using SSH command line tools AutoDeploy.bat: "d:\programs\putty\pscp" -batch -pw raspberry

C:\Users\Root\Desktop\Prime01.war pi@192.168.1.2:/home/pi "d:\programs\putty\plink" -batch -ssh -2 -l pi -pw raspberry -m "deploy.cmd"

192.168.1.2

Deploy.cmd: echo Shutting down... sudo /usr/lib/apache-tomcat-7.0.47/bin/shutdown.sh echo Shut down... sudo rm -r /usr/lib/apache-tomcat-7.0.47/webapps/Prime01 sudo cp Prime01.war /usr/lib/apache-tomcat-7.0.47/webapps echo Starting ... sudo /usr/lib/apache-tomcat-7.0.47/bin/startup.sh echo Started...

Digital Outputs & Relay Driving

Draw no more than 3mA from GPIO ports

A small relay will draw between 50-100mA from 5V power line.

Analog Input & Ambient Temperature Sampling

MCP3208 8-Channel 12-Bit A/D Converters

LM35 Precision Centigrade Temperature Sensor

Bit banged SPI (Serial Peripheral Interface) interface of the A/D converter chip programmatically

Rpi, LM35 and MCP3208 Connections

Testing other app servers namely Nginx

Scalable i2c and SPI interfaces

IoT namely Dweet.IO

SQLite
