Getting Started! with Your Raspberry Pi

Japanese Raspberry Pi Users Group

Getting Started! with your Raspberry Pi Masafumi Ohta (@masafumiohta) ! Representative of Japanese Raspberry Pi Users Group Japanese Raspberry Pi Users Group About me Used to contribute OpenSolaris Project - Now Stopped and killed :(

Now leading Japanese Raspberry Pi community and one of the moderator of ofﬁcial Raspberry Pi forum (http:// www.raspberrypi.org/forums/)

love my motorcycle and Apples. Japanese Raspberry Pi Users Group Love my Pis :) Japanese Raspberry Pi Users Group

First of all! Try Pi on Cloud! Through RPi public cloud service Japanese Raspberry Pi Users Group Agenda - What is the ‘Raspberry Pi’?

- What is useful for Raspberry Pi? thus dare not to unbox?

- The future of Raspberry Pi (Activities of Raspberry Pi Foundation)

- Tips through the meet-up

- About Japanese RPi Users Group Japanese Raspberry Pi Users Group Plan in 2006 Raspberry Pi planned in 2006 for the students - less skilled in programing.

Eben Upton thought in the beginning time of ‘personal computer’ we used to use programable PCs -Commodore 64, MSX, X68000 but.. Japanese Raspberry Pi Users Group Pi’s Goal Programable in many language

Feel interest for children - easy to go programming through game and video

Small and robust so that children could carry - hard to be broken! Japanese Raspberry Pi Users Group

Model A Model B SoC Broadcom BCM2835 (CPU+GPU) CPU ARM1176JZF-S 700Mhz (ARM11) Broadcom VideoCore IV GPU (30 Cores GPU Unit,Full HD, H.264 HiP) Memory 256MB 256MB、512MB USB 2.0 ports 1 2 Video outputs Composite Video,HDMI Audio outputs 3.5mm jack,HDMI Onboard Storage SD/MMC/SDIO Onboard Network none 10/100Mbps Low-level peripherals GPIO,SPI,I Other peripherals CSI(for Camera),DSI(For Display) Power ratings 500mA 700mA Power source 5V(Power from microUSB type B or GPIO port) Japanese Raspberry Pi Users Group Pi is cheap,but Many has no plan and say:

Throw away to the toy box..

leave it alone..

Giving away to friends..

..Why? Japanese Raspberry Pi Users Group In fact.. CPU is very poor..

Need PCs for OS preparation?

Run some Apps like ordinary PCs?

Really handle with ease?

Really it is friendly and fun? Japanese Raspberry Pi Users Group Need to consider Top 10 Raspberry Pi Myths and Truths

http://www.hanselman.com/blog/ Top10RaspberryPiMythsAndTruths.asp x

it depends on situations - useful or not Japanese Raspberry Pi Users Group PC for preparation? New Out-of-Box Software will help you pc-less installation.

copy the image to SD card and put in your PRi and boot not using ‘dd’

You can choose the OSes for RPi

Easy to recovery Japanese Raspberry Pi Users Group

NOOBS is useful installation tool - choose OSes and easy to recover (reset) when corruption. note can use from VNC customize NOOBS Japanese Raspberry Pi Users Group Useful for Desktop? is totally very sloow to use though using maynard - new desktop

midori (lightweight browser) is so-so but chrome is too slow can’t be bared also sylpheed is good but works too much slow if you have much more mails in your box Japanese Raspberry Pi Users Group

Maynard is new desktop system for RPi - based on Wayland.now under development Japanese Raspberry Pi Users Group Useful for Servers? Yes,that depends on how you use it.

music appliances - shairport,Raspbmc,volimio.. work good and you can customize it as you own- sure,works on Linux!

Check the resources CPU and memories - recommend to use ‘lightweight’ Japanese Raspberry Pi Users Group

Hiﬁberry is easy to use I2S board -need I2S soldering but it works out of the box including drivers in Raspbian. Japanese Raspberry Pi Users Group Raspyﬁ+Streaming

Old wheezy would be downloaded http://downloads.raspberrypi.org/ raspbian/images/

*sometime it happens on your Pi update make harm to Apps..use old Raspbian if it happens.

Jack Audio for Raspberry Pi download http://wiki.linuxaudio.org/wiki/ Japanese Raspberry Pi Users Group Running for 24hours? Yes,choose the cases has good airﬂow to keep your RPi being cool,or being down or freeze we can’t expected.

be careful using microusb power - choose good electric powered usb HUB to use continuously your RPi.

much more lower watts than x86 servers! Japanese Raspberry Pi Users Group

Rack-like(open-air),enough height to add some equipments. Japanese Raspberry Pi Users Group

almost sealed case might cause freezing your PRi thus hard to work 24 hours a day. Japanese Raspberry Pi Users Group Useful for Program? yes,it is very good for using such as twitter-bot or writing some codes to try some.

Of course be careful CPU,Memory resources - it very poorer than your usual PCs! Japanese Raspberry Pi Users Group

Raspberry Pi Foundation collaborate with Oracle, Porting Pure Java to Raspberry Pi (Raspbian) Japanese Raspberry Pi Users Group Useful for Games? Since such ARM Linux devices are born some has been porting the old games to the devices. - ex.GP2X,Pandora

lately Broadcom opened the Videocore driver for RPi and had a contest porting QuakeⅢ - are going to port and make many games on RPi Japanese Raspberry Pi Users Group

Old Open-Linux-based game machine GP2X Japanese Raspberry Pi Users Group

Quake3 works good with 30 GPU unit on RPi Japanese Raspberry Pi Users Group Comparing others Beaglebone - ARM Cortex 2 Cores but default is low clocks and need to be care unexpectedly stops using Beagle.

(there are anything issues unexpected stop..some says the issue of ‘usb- power’ on Beaglebone) Japanese Raspberry Pi Users Group

see cpufreq-info and cpufreq-set controlling CPU performances (default is ‘ondemand’) Japanese Raspberry Pi Users Group

I tried to run for 24 hours using tweet bot with old BB (ubuntu 14.04) but can’t work over a day.. Japanese Raspberry Pi Users Group Comparing others BAT-MINI - Intel Bay Trail-M PC (we know as ‘LIVA’ of ECS.

Works good but now focusing on Windows and Desktop(ﬁrst windows now porting..)

Works much more faster than RPi

no so care of kernel update :-p Japanese Raspberry Pi Users Group Tips for using RPi *rpi-update latest raspbian kernel for developers - make sure whether you can really update or not. (So is apt- get) so apps still old and ‘will not’ work.

*serial-using through GPIO - use GPIO port connecting your RPi with serial port,can’t use USB with it Japanese Raspberry Pi Users Group

Use FTDI Card connecting GPIO port on your RPi, you can use serial-login from your PC Japanese Raspberry Pi Users Group Future Compute Module - can be delivered in August..will delay a bit

Continue improving Software - Pure Java with Oracle and etc..

Website improving - multi-lang website for non-English natives. Japanese Raspberry Pi Users Group

Raspberry Pi compute module,which Eben planed last year,will be released in Summer(a bit delay..) Japanese Raspberry Pi Users Group Project There are interesting projects in Japan.

Now Japanese RPi Users Group introducing some projects to all over the world through Raspberry Pi Foundation. Japanese Raspberry Pi Users Group

Akkie has famous RPi Project ‘Eject command’ something through pushing and pulling out CD’s tray see http://eject.kokuda.org/ for more info Japanese Raspberry Pi Users Group

RAPIRO is very famous japanese RPi project by Shota ishiwatari,Raspberry Pi is ‘brain devices’ controlling the motors using RAPIRO. Japanese Raspberry Pi Users Group

Program Education Gathering (PEG) is the project helping Children IT Education with RPi Japanese Raspberry Pi Users Group About Users Group Established about 2 years ago.

We have a Jam (meetup) in Tokyo and attend some IT and Makers events in Japan.

In this year we plan the event to welcome Eben again here in Tokyo :)

Latest Pics at our Raspberry Jam in April Assembling RAPIRO. Japanese Raspberry Pi Users Group Summary Please be careful using RPi for Desktop.works very slow than we expected

Audio Appliance OS is the ﬁrst step to use RPi.

Raspbian is stable OS provided RPi Foundation thus make stable working. Japanese Raspberry Pi Users Group Additional If you have no idea with RPi so you might try ‘RPi case’.

You can buy,make..do some for the case.

Assemble the case with LEGO by keika -san http://goo.gl/QTcZqf Japanese Raspberry Pi Users Group
