What the inventors of„PC“ and „WWW“ did want...

2

computation, storage and communication is personal WWW connects decentralized servers and clients to share everyone controls his/her data published to the net

...but the Mainframe Dinosaur (or Borg?) is back!

3

Mainframe architecture! (Logically) Centralized Storage + thin clients (= Smart?Phones) Facebook tries to become „The one and only Internet Portal“ The operator of the Computing Center owns the User and the World... (they even know things about you that you don‘t know) Millions of different Apps replace the universal Web-Browser concept and try to inject advertizing and data collection everywhere The user is not using the Web but becomes an object in the Web Cloud & Centralized Services (iTunes, AppStore, FaceBook, Google, ...)

You donʻt believe?

  • Marketing and urban legends tell you:
  • No.
  • not every bit and piece is open and extensible or even long-living
  • Try to provide your own home screen to iOS. Even Facebook Home failed.
  • Try to connect a hardware keyboard. If you are lucky you have an USB host port.

But do you have the driver?

  • Try to get an upgrade for your 2 years old Android device.
  • Try to understand why your device fails in a specific situation.
  • Try to make sure your data is safe.

4

Android and iOS are open enough for everybody. Yes!

OpenPhoenux stands for

participation by everyone extensible hard- and software - DIY (e.g. 3D case) allows to inspect what the system is doing can be repaired using standard parts long-term support (e.g. software upgrades for an 2007 Neo 1973) fights planned obsolescence through open hard- and software no central, intransparent, stock exchange listed instance that gives directions hardware production near to users (Europe) under fair labour conditions independent from the "modern mainframe" and back to the networked, decentralized web everybody plays client and server roles and keeps control over his/her participation makes the technical system transparent, not the user

Hardware

  • GTA02 hardware (Openmoko Freerunner)

did go out of production in 2009

  • How do we improve the hardware?

1.open kernel for big ${BRAND} –> reverse engineering 2.order design from some ${MANUFACTURER} –> hope for openness and long-term support 3.DIY, “Use the source, Luke!” –> GTA04

Mass production: GTA04A5

  • GTA04A5 revision of PCB is ready to go

to production

  • small modifications to replace obsolete

components or improve production process

  • fix small bugs
  • Price is still high due to small batch size
  • But: there are not enough orders to start

a new batch

(200 units could be produced within ca. 8-10

Is this a problem unique to OpenPhoenux?

  • No:
  • - Ben Nanonote
  • - Vivaldi (Spark)
  • - Always Innovating, GeeksPhone, ...
  • What is the root cause?
  • - building hardware costs money
  • - components get only cheaper in high quantities
  • - small projects donʻt have the financial backing to buy high enough quantities to fulfill usersʻs price

expectations that are defined by big players

  • Kickstarter?
  • - US based
  • - needs something unique and new that attracts *new* customers/consumers (like Pebble, RFduino, ...)
  • - but must also be comparable in price to alternatives (e.g. Nexus 4)
  • - needs a big team to prepare a professional campaign or will fail immediately
  • - the quality expectation is very high!

Number of Users typical cost per unit

  • Community Software is inherently cheaper than commercial
  • People compare prices of production batch size 1 Mio-units vs. 100 units and find the

commercial (closed) HW much cheaper than the community developed (open) device

  • „... too expensive!“, „... scam!“, „... Vivaldi announces 200 EUR“!
  • there is no solution or „white knight“ - open hardware is and will be more expensive

Hardware

We could do a lot of things, if there were more support by interested people, e.g.:

  • build many more GTA04A5 boards
  • build new complete devices with 3D printed

cases

  • build a lot of Letux 7004 tablets
  • protoype a Cortex A15 variant with bigger

display and LTE

  • work on a hardware keyboard

  • Due to the open bootloader, open drivers

and open documentation it is possible to port any OS to the GTA04 platform.

  • Are YOU interested to port e.g. WebOS,

FirefoxOS, UbuntuPhone, SailfishOS, $ {your_favourite}OS to the most open hardware platform available?
