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.
