Design reviews are good engineering practice in many industries, so even though this is a volunteer project we've decided that we will do one for Cosmic Pi! We've just published our current main electrical schematic on the open hardware repository for open comment. We'll be holding a physical design review open to anyone interested at CERN on Thursday 7th July from 5pm in Prevessin, however attendance is restricted to those who already have a CERN access card in the course of their professional activities. However, we've also put everything you need to participate virtually on our page at the open hardware repository - so everyone can participate, regardless of where you are in the world.

Our main schematic as of 04/07/16.

Our main schematic as of 04/07/16.

Here is a link to our current main schematic (drawn in Eagle, currently available in PDF) and the Bill Of Materials (BOM in csv and xls formats). 

We will be following the approach and procedures set out here for the design review. At the moment we're only making the schematic available, once we've been through and addressed the comments we'll probably do the same thing for the PCB layout. If you would like to participate virtually in our design review please head on over to the open hardware repository and check out the schematic, or if you want more information please don't hesitate to get in touch with us directly. For those who wish to participate please try to send us your comments before 12 noon GMT on the 7th July, so we can go over them during the physical meeting.

Based on our Facebook post yesterday, we've already had 2 sets of replies with detailed comments highlighting and explaining fixes for issues we've observed on our prototypes, so we would like to thank those who have participated so far. We will endeavour to keep the list of comments on the main schematic page up to date, to avoid duplication of comments up to the review, after which we'll be releasing an updated schematic.
