daFred added a comment to T423: GitHub Informational Modeling.

A common origin could be a good idea in some cases but in Austria we say: "Du kommst in Teufels Küche" ("you get into devils kitchen.." :-)) if you change any part like the hight of a connector or a socket. You have to change this distance in every part in the whole chain. This is not a way to go. There have to be some defined interconnection points on every part but no dependency to any common origin!

The fan is rotating with 2000 rpm! I don't want this blade close to my head while filming!
And sadly the design is not open source, they sell licenses....

I also don't like the connection to guns but the coating seems to be very sturdy and resistant and they offer a lot of colors too.
There are two cerakote partners in Vienna (and one is related to cars and not guns :-) ) maybe we can take a look....

daFred added a comment to T421: establishing a naming scheme for Beta assembly revisions.

If we call the baby with the full name "Apertus Axiom Beta" the version name should be as short as possible. Shortest would be one character and we can build 26 versions. Subversions could be A1, A2....
And we still can give them alphabetical nicknames.
The name on the identification label (with serial number) should be short and straight...

What do you think about naming it like JJMM e.g. 1505
An we could add names like Ubuntu too: 1505 AngryAbigail, 1507 BeautyBelinda
In my opinion numbers are easier to associate with versions then names. ( I just remember JJMM of Ubuntu and not the names...)

daFred added a comment to T346: Flying Camera.

We are designing a variant with E-mount. So we could save weight on the camera side, shorten the distance for the center of gravity and choose from good lightweight (and copter proven) lenses. Storing the data as a different thing....

There are aluminium cooling profiles out there. We should find a fitting profile to reduce production costs. Let's search...

pactec has nice things! So what we should find out or decide is what we should use.
Cheap and single use or a more expensive case.

daFred added a comment to T138: gphoto support wanted?.

There has to be a protocol for setting camera parameters from outside the camera (dictator, mobile phone...).
Is there already a protocol implemented? ptp / gphoto could be an option for this...
Every (supported) parameter of a digital camera can be read/set with this protocol.
The picture transfer itself is the not so important part.
