Four months have passed since we started our donation campaign aimed at the PCB design and we are now at around €6500 (27%) of the goal €24000 for the entire phase 1 of the design, and we must admit that the rate of donations is slower than what we had hoped for.
Phase 1 is subdivided in two subtasks:
1A) PCB Project € 19000
1B) Fast SI bus simulations €5000
In other words, we reached an encouraging 34% of what is required for subtask 1A.
As we really want to speed up as much as possible the activity, we decided to formally split phase 1, and not to wait to reach €24000 to start the design of the PCB.
To do so, we signed a contract with ACube Systems (company we rely on for the design) just for subtask 1A. Doing so gives the chance to start right now the PCB design. At the time of signing the contract, we paid €6000, the amount required by the designer to start working.
One of the reasons forcing us to speed up the planned activities, is linked to the availability of the Slimbook model “Eclipse” that will not last forever, very much like any other commercially available products such as the electronic components we selected during the electrical schematics design phase. In fact, the electrical schematics are customized for the pinouts of that specific Slimbook model, and the PCB design will be specifically shaped to fit in the Slimbook Eclipse chassis. Because of these constraints, we have to finish the PCB design (phase 1A), the fast SI bus simulations (phase 1B) and the prototypes (phase 2) around this summer.
We fixed the end of April 2020 as the time-limit for phase 1A, so we have 3 months left to raise the remaining €12500. As you may well understand this goal is quite ambitious, but it is necessary if we don’t want to risk to fail.
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
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.
We announce the cooperation with C-Media. C-Media is a global leading audio IC/software solution provider.
In this post we want to explain one of our latest achievements. During the present year we have been looking for an audio chip to be included in our motherboard. We found that the CM8828 HD-Audio controller and CM9882A Codec family was a good candidate. After some discussion with them explaining our project, they decided to support us. Furthermore, they have sent the Evaluation Board to Acube.
Maybe more important is the fact that C-Media will provide the needed chips for the production of our notebook. They know that their chips will be in our Open Source Hardware motherboard and will provide us with the needed information to write drivers as may be needed. In addition to this, we have ordered three pci sound cards based on CM8828/CM9882A to test with our T2080 Devkits and for Acube developments.
In the end, all these little steps are very interesting for our project, as this audio chip has high end specs but the most important point is that we have a direct and good communication with the manufacturer. We want to thank C-Media for supporting our project and believe in Open Source Hardware.
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.
In our last post we stated “we hope to publish the initial schematic design before the end of February 2019”. Unfortunately a series of problems arise that we will try to explain in this status update.
As you may probably know, at the end of the first donation campaign we received four incremental releases of electrical schematics from the designer, the last one on the 11th of January 2019. We started a validation task at each release prior to their publication and each time we ended up sending back the schematics because we thought some design decisions had to be improved. These hardware reviews are quite complicated, and we would need additional volunteers, possibly hardware engineers able to properly address the task. Please, contact us or fill the collaboration survey if you can contribute.
At the same time, we were continuously evaluating various notebook chassis options, striving to find a suitable chassis that could fit our motherboard that has a MXM video card. The goal here was to identify an empty chassis that could be bought without a motherboard and with a life cycle of at least two or three years, which is the envisioned time-frame covering our laptop project.
The hardware designer that was paid thanks to donors is stuck waiting for the final notebook chassis as he requires the pinout specifications to finalize the design.
These are the reasons why the development of the electrical schematics is frozen since the 11th of January 2019. As a result, also our collaborators that have volunteered to validate the hardware schematics are stuck, as well as our selected product maker ACube Systems.
Identifying a suitable chassis is taking an unexpected amount of time and it is terribly delaying the second campaign aimed at the PCB design. Last year we had a meeting among both Power Progress Community associated members and the core group that is coordinating the project, and we all agreed to start the second donation campaign only after publishing the schematics resulting from first campaign. However, the amount of accumulated delay arise doubts among the participants on how to solve the current impasse, and we decided to ask the donors to give their opinion about whether to start now the second campaign (link) or keep waiting the publication of the result of the first campaign. If you are willing to actively support the project, feel free to express your opinion about the matter.
Our hardware volunteer team and ACube Systems are still reviewing the next round of documentation for selecting some key components that heavily depend on the selected chassis.
So far we have identified some potentially suitable chassis. However, some of them are designed to host a separated board to manage the batteries, a board that does not exists in our design, and some chassis have a dedicated space for a separated ethernet board, and again, others do not have a thermal design compatible with the heat generated by an MXM video card. The problem here is that the hired hardware designer stated very clearly that he is not willing to make an extra work to alter the initially agreed design features of the main board to accommodate it in a chassis requiring a very different internal layout. In other words, splitting functions in separated boards is out of question.
At this time the key question is: how much time is required to identify the correct notebook chassis?
Unfortunately, given our very limited spending resources and the experience we had so far, we are not able to make any speculation at this point. We strongly believe that it would be better to make a wise choice requiring more time, rather than an hasty solution now, because any wrong decision would risk to compromise the feasibility of the entire project.
We are not a private company aimed at making a profit out of this project in order to survive, in fact we don’t sell anything. We are a group of hardware enthusiasts more or less structured in a non-for-profit association. We are doing our best to face strong limitations to achieve what we knew since the beginning was a very difficult and complex goal.
Taking all of this into account, we think that publishing to a wider audience now a very incomplete electrical schematics could impact way too negatively our project and the donors expectations. On the other hand, we are conscious that we are delaying for way too long the promised outcome of the first campaign and this fact too have a great impact to our credibility.
We are moving forward extremely slowly, that’s for sure. You know the requirements and the extremely limited actions that we can make, mostly due to extremely tight financial constraints.
After all what was said in this status update, we delivered to the donors the current version of the schematics, stressing on the fact that they should be considered only a draft not yet ready to be shared with a wider audience
In the end, we still strongly believe in the project, we are facing a contingent problem (the chassis) that it will be soon or later be solved. If you can help you are more than welcome.
The schematics are still under review by our hardware volunteers and Acube itself, we hope to publish the initial schematic design before the end of February 2019 in our gitlab repository. It will be a Work-In-Progress schematic design. As the schematic design is a Work-In-Progress we will only publish the pdf. We will publish the Orcad files when the schematic design will be finalized. In parallel to the schematic design being released to the public, we will begin the PCB Layout Donation Campaign.
The schematics will be updated later including all laptop external connectors actually present on the laptop chassis, due to the selection of the chassis to use is still pending.
We plan to begin the PCB Layout Donation Campaign before the end of February 2019.

Sfscon Bolzano – Italy – November 2018
At 16th November 2018 at Sfscon.it we have made our project presentation speech in the bigger room with the presence of around one hundred people ( even though it was late and it was the penultimate) .
We have talked about the steps done by us for our project of Open Hardware PowerPC GNU/Linux based Notebook. We have disclosed a preview of our electrical schematics and informed about the next steps.It was for us an honour to present our project near important speakers and just before Simon Phipps which is the President at the Open Source Initiative (OSI). We thanks so much IDM Südtirol and Linux User Group Bozen-Bolzano-Bulsan of the Free Software Conference Bozen, South Tyrol, that are the organizers for such an opportunity. You can find the program of the Sfscon 2018 at this link.

Open Source Laptop Chassis Design
Thanks to some collaborators there is a first setup of the design of a future Open Source laptop chassis design, done in FreeCad. You can find the design in our repo.
If you like to collaborate to the Open Source Laptop chassis design please contact us.
We want to thank the University of Campinas in Brazil for their support and for the excellent service (called Minicloud) they are offering. The Minicloud provides free access to POWER virtual machines that can be used for development, testing or migration of applications to POWER. The virtual machines of Minicloud run on OpenStack, which supports running a large number of virtual machines on a single scale-out Linux server. We are using their infrastructure to build our Yocto based distribution. Currently we are upgrading all the project to Yocto 2.6 and this task is being performed in a Minicloud VM. If you have a project which follows the basic rules explained before, you can ask for an account here https://minicloud.parqtec.unicamp.br/minicloud/ .
