As we stated in a previous article, we have already contracted ACube Systems and the PCB design work has started. This post is a first report about the work in progress in relation to the PCB design.
These days, the designer is analyzing the Pericom Switch with the direct support of Pericom personnel.
The Pericom PI7C9X2G608GP is a PCIE Gen 2 Switch that provides one upstream port supporting x4 or x1, and 4 or 5 downstream ports that support x1 operation. This chip has a Power Dissipation of 1.2 W.
In our mobo the PI7C9X2G608GP is essential as it allows to connect one 4x PCIe 2.0 controller of the NXP T2080 CPU with four 1x PCIe chips/cards: M.2 3G/LTE card , M.2 WiFi card, 1x Renesas USB3 Controller and 1x C-Media Audio chipset.
At the end of August of 2019 we published the first version of the schematics in pdf format. Then, in October we uploaded the second version and after that the 13th of November we released the Orcad source, accomplishing what we promised.
Schematics Source in EDIF published and ready to be converted to KiCad
Now we have exported it even to EDIF format, to make easier for new volunteers to convert it to Kicad Format. To convert from EDIF to Kicad we have found edif2kicad tools https://github.com/svn2github/edif2kicad but we are sure you will find other tools or even you will be able to create a new one
It’s the first time that Power Progress Community and Acube Systems present together the project. This presentation is very comprehensive.
We thanks very much LugVi for the perfect organization and excellent work of video editing done with Olive in Flathub and the good participation from very active and expert people in free software and competent in hardware, that come from all the area (Veneto). It was very exiting and a pleasure to answer to all the questions!
Video of our presentation held the 15th November at sfscons.it Free Software Conference in Bozen, South Tyrol – Italy – where we have talked about “The Butterfly Effect of an Open Hardware Notebook Motherboard”.
For the second time we were giving a talk to the GNU/Linux Valencia Group, a local Linux group located in the city of Valencia, Spain, which is doing a great job promoting Linux and open source in general. Guillermo gave a brief explanation of the project from the beginning to the present, the objectives, technical specifications, other related projects of the Power Progress Community association, FAQs about the project and so on.
In particular the group was updated about everything that has occurred in the project since the last time we visited them. One of the key points was the collaboration with Slimbook, this collaboration started just because of last year meeting with the group as this company is located at the same city and his CEO is one of the founders of this Valencian group. The company will provide the laptop body and is supporting our team giving all specifications we need.
You can find an article covering this meeting in the GNU/Linux Valencia group page (in Spanish):
Linux Day Milano – Italy 26th October 2019
This year we have as expositor our running DIY wooden desktop case with the T2080rdb devkit, with our new Power Progress Community T-shirt, with our Posters with our “Revivo with Scratch” manifest , searching notebook to recondition.
People are quite exited using our PowerPC 64 Desktop based on the same CPU NXP T0280 of our future notebook motherboard.
Many young people reach our table and talk with us.
Open Hardware release of the Printed Circuit Board (PCB) design for the motherboard of the GNU/Linux PowerPC Notebook.
The initial 2,703 euro of donations of this campaign arrive most from recurring donations that continue to arrive from the old campaign after reached the old campaign goal.
Our hardware group identified in early 2017 a desirable list of components and a set of features of the laptop. In June 2017 we launched a first donation campaign that was aimed at paying ACube to design the electrical schematics and a year later, in June 2018 we reached the goal of collecting €12,600 and finally started finalizing the design. Here you may download the resulting schematics of the 1st donation campaign.
As of today, the notebook specifications are the following (subject to change):
Few days ago we announced that Slimbook will provide the enclosure we need for our Open Hardware PowerPC notebook. In addition to that, we have published in our repository the pdf containing the new version of the schematics. Further updates will arrive during the following days ( the Orcad source files will be available during October)
One of the main points when you are designing a laptop is the relationship between the motherboard and the enclosure. It is not a good idea to design the motherboard if you don’t have the chassis. At the same time, the enclosure has to take into account how the motherboard will be.
Now we are happy to announce that Slimbook will provide the enclosure we need for our Open Hardware PowerPC notebook. ACube and Slimbook are collaborating since the beginning of this year, exchanging information about components disposition and pinouts, thermal dissipation and so on.
Slimbook is having a great success selling their own Linux laptops (such as the ProX) and mini PCs world-wide.
Due to this collaboration we have almost everything we need to achieve our goal in terms of technology.
Electrical Schematics final version
We want to update you that first days of October we will publish in our repository the pdf containing the final version of the schematics. After that, during October, the Orca source will be available as well, tailored for the Slimbook chassis. This means that the design of the PCB will fit inside the Slimbook chassis.
In case you are able to convert Orca source to Kicad you are welcome to do it. If you have any issue when doing so, contact us and we will be happy to provide some help.
New ppc64 applications in our repo
Lastly, we have patched the following applications for ppc64 (Big Endian) : arcticfox, palemoon, mame, fs-uae, libx265, qemu, midori. They run on PowerMac/ImacG5 ( Power4 processor) but also on more recent Big Endian ppc64 processors such as NXP T2xxx and T4xxx.
We are also working on many other complex applications like Blender that require the creation of dedicated groups for the distribution of the necessary effort.
We’re performing tests, reporting bugs and suggesting workarounds to complete the installation of Debian 10.0 using ISOs released by the maintainers of Debian ports for ppc64be.
If you want to join the software workgroup and help these software tasks feel free to contact us.
Above all, one of the greatest problems preventing us from finalizing these schematics was the missing chassis required to take a series of very important design decisions. Finally, very recently, a chassis was selected and is now in our hands, paving the way to accomplish the goal.
In April we asked your opinion on either publishing an unfinished work or wait for better quality schematics. The Core Team chose to wait and “Send the information (the work in progress pdf of the schematic design) only to the 132 donors and kindly asking them to not publish”.
At the end of June there was an important meeting between Acube and the designer to discuss the suggestions from our Hardware team, and another topic was how to adapt the schematic to the new chassis. In fact we have prepared the next steps for the PCB design.
So now we have this modified block diagram that could have further few minor changes.
Currently, the designer is working to update the schematics. This task is expected to be completed on August.
In the meantime, the Core Team we voted again in June and this time we have decided to publish the pdf of the current version of the schematic. That does not contain the updates we are expecting in August.
In other words, the schematic that we have uploaded to our repository is the same pre-release version that we have sent to the donors at the end of March 2019, and it should be noted that it is an alpha version. The only difference from the donors’ version is that it contains the recently selected Open Hardware license that is the Cern Open Hardware License v 1.2 (Cern OHL).
We have selected Cern OHL because it is specific for open hardware and it covers aspects regarding hardware production. It has the same viral effects that other open source licenses have but taking into account that there is a licensor of the hardware and another part that is manufacturing it.
The current version of the schematic is published in our repo in gitlab.
It’s with joy that the Power Progress Community proudly announce the complete funding of the Hardware Research and Design phase for the Electrical Schematics. This phase has achieved the identification and design of all aspects of the motherboard reducing uncertainties related to the hardware specifications and, consequently, the production costs.
After reaching the amount of 12600€, the electrical schematics will be delivered to us in a month by ACube Systems. The final design resulting from this phase will be made public as soon as possible.
We are now dealing with the Open Source Hardware Association, asking them if we can certify as “Open Source Hardware” the documentation produced in this phase or, instead, we should wait until the board design will be entirely finalized. What is more important, we now have to choose which Open Source Hardware license to adopt for distributing our Electrical Schematic. If you are an expert on this field, please join us!
We are so very grateful with all the 128 donors that trusted us and actively contributed in achieving this first goal! We also thank all the people that supported us in spreading our project letting us able reaching a much larger audience.
We remind you that this is a first step of a much larger funding campaign planned more than a year ago. We still need new donations, and to do so, we need reaching even more people, so please, do not hesitate spreading the word. We are fully aware on the importance in publishing soon the Electrical Schematics that came out of the first campaign, as we want to show that we are able to respect the promise of delivering a fully open hardware output, hoping that more people will feel confident in further supporting the project.
The list below contains the planned campaigns and their corresponding funding goals:
[Achieved!] Hardware components research, analysis of the architecture, and design of the electrical schematics [12.600 euro]
[Upcoming campaign] Printed Circuit Board (PCB) Gerber format delivery of the electrical schematics [11.950 euro]
Production and delivery of five working prototypes [8.800 euro]
Hardware testing using software provided by the producer (ACube) [14.400 euro]
Pre-certification CE certification [12.500 euro].
Please, do not stop donating, even if the next campaign is not officially launched yet. Any new donations will automatically be transferred to the phase 2 donation campaign called “Printed Circuit Board (PCB) Gerber”.
We will soon circulate the next issue of our newsletter among subscribers that will contain a very short questionnaire asking whether people are willing to donate to the PCB design donation campaign and their advice on how to carry out a better campaign. This will be necessary to evaluate how much we should “invest” on further publicizing our project for enlarging the involved community and will help us focusing on what we should change in order to reach the goal in a shorter period of time.
During the last week of October we were presenting our Open Hardware PowerPC Notebook project in the Linux Day Italy and Amiga32 in Germany. After that, we also introduced our Open Hardware project in Alchimie12 in France.
Since 2001, Linux Day is a distributed initiative to learn and promote Linux and free software.
This year the main topic of the Linux Day was “privacy and individual confidentiality”.
The event consists of numerous local events, organized independently by groups of fans in their respective cities, all on the same day. In this context, you can find talks, workshops, technical assistance, gadgets, forums and practical demonstrations.
