"Open Revolutiion" is just a marketing name.
The only eCCR with open source that I am aware of is the published GPL'd K1 code and PCB files.
AD_Ward and I went around on this a few months ago, and the conclusion was that OR is not open source / open design - its a marketing name for exposing the validation protocol(s) used in the design to public scrutiny.
Now that is in and of itself a fairly significant thing (and a first in the industry), so in no way is this an attempt to "slam" AD_Ward and what they're doing - but its not "open source" - its a full-on commercial product full of trade secrets, just like all the others out there.
We discussed this on another thread.
Open Revolution is not open source as per GNU type licences. Open Revolution does publish the sources for all to see, publishes the safety process, the verification models and their sources, the circuits, their safety review, the mechanical drawings.
Open Revolution is not an initiative from Marketing. It is one from safety engineers, to meet the best global practice for safe design.
There are no trade secrets. All circuit diagrams are already published along with the safety review and MTBF & MTBCF data. Full mechanical design will be published. We recently approved publication of the design procedure meeting EN61508 even though this is commercially very valuable.
Our objective is purely the safest possible system we can design.
About 6 years ago, I had a conversation with Iain Middlebrook of HSM Engineering. We agreed that either company could easily make rebreathers or supply rebreather technology. We both agreed not to for Sports Rebreathers, until we could meet the 1 billion hour safety requirement with full gas monitoring (incl. CO2). HSM and DL are direct competitors in several areas. However, we have a high regard for Iain's integrity and the altruism of safety comes first in their business, just like in ours. We both believe there have been a string of CCR deaths from poor design. We both would like that to end. We are exposing our work under the Open Revolution initiative as part of our contribution to that goal. HSM are offering a free rebreather test facility as part of their contribution to the community (to which we are contributing one of our breathing machines).
Diving gives access to a wonderful environment under the sea, that it is only really diving that is preserving. When we dive I for one feel grateful at the priviledge of seeing things under the sea, live, in ways previous generations never could. I hope more can enjoy and be part of this. To make that come about, we do need safer equipment. If there is a better way than the Open Revolution initiative to do that, I am keen to hear of it. Please tell me the solution rather than the problem.
Cheers,
