Ergonomics Workgroup
1 Meeting 27th of October, 2014
Are there HDMI connectors pointing away from the PCB surface they are mounted to? -> http://lab.apertus.org/T93
Lets research metal bending processes and prices.
Lets create a Grip Handle Concept and physical mock ups for testing.
We need to design the stray light filter part in the AXIOM Beta as independent part from the lens mount so swapping image sensor means you do not need to swap the lens mount part as well for the matching stray light filter.
Cheese plate concepts for camera back plate and top plate (illustrations will follow).
Lets research leather (fake or fair) as material for some camera parts (hand grip, etc.)
2 Meeting 3rd of November, 2014
2.1 Researching the lens mount patent situation
Mechanical dimensions cannot be patented so anyone can build a mount that particular lenses.
Of course the manufacturer names (Sony, Canon, etc.) are trademarked so we cannot advertize any mount as "Sony E-mount" we can only call it "e-mount" or "compatible with e-mount". The word "e-mount" is very likely not trademarked.
The electronic data exchange protocol is under a Sony/Canon/etc. licenses and to acquire it you need to sign contracts and pay fees, etc. In Europe though it is not illegal to reverse engineer something if it is required for you to make specific things "work" so we will be able to listen to what the lens is saying and being told to do and would be able to create software that sends/receives "similar" commands. This is in full compliance with the law.
2.2 Camera Enclosure Surface Finish Notes
The typical options for surface finished of aluminum are sandblasting, abrasive blasting, anodizing, painting, powder coating.
The typical camera surface finish is called "Runzellack" which translates to: wrinkle paint.
Painting Aluminum is not a trivial process.
Labels can easily be CNC engraved, then painted and the wet paint wiped away, that way the paint only remains in the engraved areas and dries there.
laser engraving is another cheap way to create labels but we would need to outsource that
2.3 Manufacturing Material Notes
There are innovative wood-plastic combinations: http://www.fasal.at/ that feel similar like wood and are bio degradable. These can be used like any other injection molding raw material. The material is still in research and long term integrity, UV-resistance, etc. are unknown.
3 Meeting 17th of November, 2014
PCBs should have rounded corners to match the round corner design of the AXIOM CI and to reduce risk of injury with sharp PCB edges.
We will inquiry receiving samples from a powder coating service provider.
Method for getting HDMI/SDI connectors to the side/back of the camera:
