Introducing OpenPhoenux Neo900

openphoenux-logoThe latest device in the OpenPhoenux open hardware familiy is the Neo900, the first true successor to the Nokia N900. The Neo900 is a joint project of the Openmoko veteran Jörg Reisenweber and the creators of the GTA04/Letux2804 open hardware smartphone at Golden Delicious Computers. Furthermore, it is supported by the N900 Maemo5/Fremantle community, the Openmoko community and the OpenPhoenux community, who are working together to get closer to their common goal of providing an open hardware smartphone, which is able to run 100% free and open source software, while being independent of any big hardware manufacturer.

With the big ecosystem of free and open Maemo5/Fermantle applications, the hacker friendly N900, which provides an excelent hardware keyboard, the variety of free operating systems of the Openmoko community (SHR, QtMoko, Replicant, …) and the experience in designing and producing open hardware devices of the OpenPhoenux community (e.g. GTA04), they want to bring the best of all worlds together in one single device, the Neo900.

The Neo900 is meant to be an upgraded N900, with a newly designed and more powerfull motherboard, which is based upon the existing and tested OpenPhoenux GTA04 design. Together with the nice housing of the N900 (e.g. slider, hardware keyboard, big screen, …), this is trying to get “the hackers most beloved device”. In the same spirit of the OpenPhoenux community, which created unique cases for their GTA04 devices out of aluminium, wood or 3D printing, there is also an effort to build an aluminium housing for the N900, which might lead to personalized and self-produced cases for the Neo900 in the future and thus the independence of spare parts of N900 smartphones.

Due to the fact that the Neo900′s new motherboard is very similar to the GTA04, it is possible to reuse most of the low level software stack like development tools, the Bootloader and the Linux Kernel from the GTA04 project, with just minor modifications applied. This will speed up the software development process of this new open hardware platform a lot!

To fund the development and prototyping of this new open hardware device, which is made in Germany, a crowdfunding campain has been started a few days ago, in order to collect 25.000€ (which is by now already halfway reached!). Depending on the outcome of this fundraising the project might be able to provide better hardware specs than the following minimum keyfeature set:

  • TI DM3730 CPU (OMAP3 ARM Cortex A8) with 1+ GHz
  • 512+ MB RAM, 1+ GB NAND flash, 32+ GB eMMC, Micro-SD-Reader
  • 3.75G module for UMTS/CDMA; 4G (LTE) optional
  • USB 2.0 OTG High Speed
  • GPS, WLAN, Bluetooth
  • Accelerometer, barometric Altimeter, Magnetometer, Gyroscope
  • support of N900 camera module

If you want to see the N900 to live on, help the independet open hardware community to succeed, or are looking for a new, hacker friendly smartphone, you should consider to support the fundraising with a donation. If you donate 100€ or more, your donation will also serve as a rebate for a finished device, once they are ready.

[Update 2013-11-04] The goal of 25.000€ is now reached, less than a week after the fundraiser started! Thanks to everybody who donated and spread the word and thus helped to make that happen. If you want to qualify for the rebate on the finished device, it is still possible to donate.

Let the OpenPhoenux fly on!

OpenPhoenux at FOSDEM 2013

openphoenux-logo
The team of OpenPhoenux presented the development process of the open hardware and free software powered mobile plattform “GTA04″ at FOSDEM 2011 and 2012, including working prototypes and preview-boards for developers.


OpenPhoenux-3704Now, that the OpenPhoenux has taken off to reach a broader audience, we’ll show off all the open hardware (prototypes of new products and finished devices) at FOSDEM 2013. We hope you’re already eager to have your hands on the latest and greatest open mobile handhelds, which will be presented at our booth!

All of those are based on the GTA04 open mobile plattform, whose latest revision GTA04-A5 is ready and waiting for pre-orders to finance the next production run.

In addition, there are still a few complete GTA04 (revision A4) smartphone units on stock at the Openmoko reseller Pulster.eu. Contact him for further information.

Those are all great hardware projects for Linux/FOSS enthusiasts and freedom lovers! But the World of OpenPhoenux is not limited to hardware gadgets, but is connected to several other open mobile and communication projects, as well:

SHR    

So, if you’re visiting FOSDEM this year and are interested in open mobile communications it is a must to drop by the “World of OpenPhoenux”-booth (No. 3) in building AW, right next to Jolla/Sailfish, Hackable Devices/MakerBot, Enlightenment and more!

We’re looking forward to meet you there, answer your questions and demo the devices to you!

Openmoko/OpenPhoenux GTA04 jumps off

The Story

All started off after Openmoko Inc. began to ship the Openmoko Neo 1973 (GTA01) and Neo Freerunner (GTA02) in 2007, which are fully open source smartphones. A dream became true for many open source lovers and technology enthusiasts at that time.

Sadly, Openmoko Inc. canceled their efforts for an open smartphone in 2009. But due to their openness (schematics, hardware specifications, software) it was possible for enthusiasts from the Openmoko community, with great support from Golden Delicious Computers (one of the german Openmoko distributors), to develop a new and modern open smartphone – the OpenPhoenux GTA04.


Technical Specifications

  • WLAN, Bluetooth, GPS, FM Transceiver
  • Accelerometer, Compass, Gyroscope, Barometric Altimeter
  • USB 2.0 OTG port, 2.5mm headset port, GPS antenna port, video out


Prototypes & First production run (2012)

om_beagle_hybrid
Golden Delicious Computers and the enthusiasts from the Openmoko community started off with the idea of stuffing a BeagleBoard into a Neo Freerunner case and connecting an USB UMTS dongle to it – this was the first prototype GTA04A1, announced in late 2010 and presented at OHSW 2010 and FOSDEM 2011.


Next, they started to integrate all of this onto a single PCB of the same size as the Neo 1973/Freerunner boards, so it could fit into their cases, use their batterys, antennas, speakers, buttons and touchscreens. This board was then called GTA04A2 – the second prototype, which had quite some problems. A redesign of that prototype resulted to the GTA04A3 “Early-Adpoter” boards, which were shipped to about 20 develpoers, enabling them to start with software development for the platform.

LinuxTag12The next step was to reach out to the people by presenting the project on other conventions like the FOSDEM 2012, Openmobility 2012, Linuxwochen 2012 and the LinuxTag 2012, to produce bigger batches of GTA04s. To finance the first production run of the GTA04A4 (which includes some more fixes over the GTA04A3) Goldelico collected pre-orders from interested people from the Openmoko community. They were able to collect about 250 pre-orders and were thus able to start the first big OpenPhoenux production run.

Unfortunately, “mass”-production turned out not to be an easy task. Goldelico had to find, analyse and solve a lot of problems within the production line and especially in the soldering process, which took a lot of time. Because of all the troubles the people who pre-ordered in the beginning had to wait about 1 year to finally get their devices. At the end of 2012 all problems were solved and the “Group-Tour” had successfully finished. The GTA04 team is very happy to have reached that big milestone. Now that there are about 300 GTA04s (A3+A4) out in the wild, the interest in the Linux/FOSS community seems to be growing for our project. To satisfy that growing demand Goldelico will happily produce more GTA04s of revision A5 (which will include some minor fixes over the A4).
“Now as we have finally learned everything about mass production [...], it is time to kick-start the next [production run].” (Dr. Schaller, Golden Delicious Computers)


Next production run (2013) – Out now!

DSC01512To finance the 2nd production run of about 200 more GTA04 boards Goldelico started to collect pre-orders just recently. The production should run smoothly that time, as there were no big changes and the process is known. Production will start in march 2013 and the boards should ship shortly after that.

If you’re interested in pre-ordering one of those new A5 boards, check out the Handheld-Linux store. If you’re interested in getting a complete “Letux 2804″ unit (GTA04 board build into an Openmoko Freerunner case) now you can get it from the first OpenPhoenux reseller Pulster.eu (stock is limited!).


OpenPhoenux ecosystem

openphoenux
While preparing the next revision of the GTA04 and solving production problems, the guys at Goldelico started to experiment with other GTA04 powered devices. So it is no secret, that there is already an open GTA04 tablet prototype (Letux 7004) and the ready to use GTA04 professional PDA (Letux 3704), which can be used e.g. in logistics (RFID), measurement (GPS) or guiding tasks (big sunlight readable screen & long lasting battery).
The software for the GTA04 is already in a good shape as well. Besides the Debian (squeeze) hardware-validation image, there is the Debian based QtMoko distribution and the FSO based SHR distribution, which makes the GTA04 useable as a daily phone. Furthermore, a port of Replicant (fully open source Android) is in the works. All in all the GTA04 owners in the OpenPhoenux community seem to be satisfied with their devices, so is Nikolaus Schaller from Goldelico:

“[...] I enjoy every day to be member of this OpenPhoenux community. Let’s make the OpenPhoenux fly to new levels next year!” (Dr. Schaller, Golden Delicious Computers)

I really appreciate to see our community grow again and can just second Nikolaus’ sentence. I wish the community a successful year 2013, in which we can satisfy a lot of free software enthusiasts and freedom lovers needs. OpenPhoenux – Free your phone!


Some more Goodies

There are still some more goodies in the pipeline… So stay tuned!

Open Hard- and Software Workshop 2012

Soon this years Open Hard- and Software Workshop (OHSW) will take place in Garching (near Munich) at the TUM Campus Garching. There will be a lot of intetresting topics to discuss and people to meet. Make sure to drop by if you find some time!

The agenda and further details are now available online:

GTA04 production is processing

The OpenPhoenux GTA04 production is finally making nice process. All the GTA04A4 (Group Tour 1) preorders should be ready and shipped soon!

This is the lastest batch of devices, which has sucessfully passed Golden Delicious Computers’ QA process and fulfilled the high quality claims.

After a lot of production issues had to be solved in the last months, we’ve now found a method which provides us with a good production yield. After switching to vapour phase soldering [0], we got rid of most the soldering problems.
