Meet the raspberry Pi

So this is how it started:
I bought a Rasberry Pi.

Meet the raspberry Pi

What’s a Raspberry Pi?

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn (python) programming.

Meet the raspberry Pi

  • not an open hardware (who care? ping @unixgarden)
  • Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU
  • GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode
  • GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure

Meet the raspberry Pi

  • SDRAM 512 Megabytes (MiB)
  • Boots from SD card, running Debian-based Raspbian “wheezy” or Arch Linux ARM GNU/Linux based distributions
  • Also: Fedora, Gentoo, Slackware, Firefox OS, Android
  • 10/100 BaseT Ethernet socket
  • Video outputs: Composite RCA, HDMI
  • Audio outputs: 3.5 mm jack, HDMI
  • Onboard storage: SD, MMC, SDIO card slot

Raspi are manufactured in the UK,
at Sony's manufacturing facility in Pencoed, Wales.
1 million sold in 2012.

Screen ?

 

To buy one of these monitors, search eBay for "Car TFT" and there will be loads of results. It should cost about £10 ($16). It requires a 12V power supply, since it is designed to be powered by a car battery, but you can power it with a regular power adaptor.

Cases, anyone?

Where the hell did that come from?

microcontrollers

Arduino (& Arduino-like MC)

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform (...), and a development environment for writing software for the board.

ARM CPU

In 2011: 95% of smartphones, 90% of hard disk drives, 40% of digital televisions and set-top boxes, 15% of microcontrollers and 20% of mobile computers

How many ARM cores
have you got at home?

Microsoft Surface, ASUS Eee Pad, Apple iPads, iPhones & iPods, Samsung Galaxy S II &III, Google Nexus 10, Google Chrome Book, Blackberry smartphones, Canon PowerShot A470 digital camera, Nintendo DS game console, TomTom GPS...

Wait a minute...

Who inspired?

The Joy of DIY

Texas, 1942 (Wikimedia Commons)

"Makers?"

 

maker [ˈmeɪkə] - n.
 

people who hack hardware, business-models, and living arrangements to discover ways of staying alive and happy even when the economy is falling down the toilet.

Cory Doctorow, Makers, October 2009, [read it for free]

 

related: Dreamers, scientists, hackers, self-replicators, teachers, troublemakers, laser-lovers, scouts

"Maker subculture?"

 

The maker subculture is a contemporary subculture, representing a technology-based extension of DIY culture.

 

related: DIY, electronics, robotics, 3-D printing, home-automation / domotique, open-source-hardware, fablabs, cnc tools, metalworking, woodworking, knitting, traditional arts and crafts, no-patents

OMG, I see makers everywhere!

OMG, I see makers marketplaces everywhere!

Makers go mainstream

Yet-another-revolution-gone-bankable

Just as the Web ended the monopoly of mass media, so it is now ending the monopoly of mass manufacturing. Over the next ten years, Anderson explains, countless micro-manufacturers, based on open-source design and DIY manufacturing, will help drive the next big movement in the global economy as the power of bytes—the Long Tail—is transformed into the power to make things again, the Long Tail of things.

Chris Anderson (formally of WIRED) speaks about
his new book Makers: The New Industrial Revolution

Conclusions so far

  • Raspberry PI is a hackable device: 1st value is software and hardware hackability
  • probably NSFW & not scalable AT ALL
  • hobbyist & educational purposes FTW
  • domestic robots, electronic breadboard & any pet projects that need CPU

& why not...

  • home automation
  • domestic server
  • corporate, HTML5-friendly visual dashboards
  • interactive kiosks
  • public screens
  • artistic performances devices
  • (cheap & tiny) museums 2.0 device

OK,

I'm a nerd,

show me all the

mind-blowing stuff!

“This little Raspberry Pi based project is a gift for my wife’s grandmother for her 90th birthday. Being visually impaired, she is hard to entertain but loves to listen to audiobooks. The problem is, that she isn’t able to handle a ghetto blaster or MP3 player. The solution to this problem was – tadaaaah

2012 Internet of Things Award :

The new e-Health sensor platform adds sensing capability for nine different biometric parameters, such as pulse, blood pressure, oxygen in blood (SPO2), electrocardiogram (EKG), airflow, glucometer, galvanic skin response (GSR), patient position and body temperature, to give the Arduino and Raspberry Pi Community a way to develop new e-Health applications and products.

an APRS iGate implementation using the Raspberry-Pi

APRS (Automatic Packet Reporting System) is an amateur-radio based system for realtime communication using digital packets sent over radio links. I present here, an implementation of an APRS iGate using the Raspberry-Pi. An APRS iGate is an Internet gateway that gates packets from the radio/RF side to the APRS-IS on the Internet (and vice-versa). The APRS-IS is an Internet based network that connects APRS networks from all around the world and facilitates APRS applications (like realtime postion reporting of objects overlaid over google maps, see aprs.fi)

Going to JAIL
with Raspberry Pi
& a wifi Dongle

PwnPi is a Linux-based penetration testing dropbox distribution for the Raspberry Pi. It currently has 200+ network security tools pre-installed to aid the penetration tester. It is built a stripped down version of the Debian Wheezy image from the Raspberry Pi foundation's website and uses Openbox as the window manager.
