# SatNOGS Rotator
|
|
|
|
Hardware for SatNOGS Rotator. This repository includes all needed source files for 3D printed (and other) parts of SatNOGS Rotator.
|
|
|
|
## Documentation
|
|
|
|
More information can be found in our [wiki](https://wiki.satnogs.org/SatNOGS_Rotator_v3).

|
## Repository policy - Naming Convention
|
|
|
|
According to F3 - [Form, Fit and function](https://en.wikipedia.org/wiki/Form,_fit_and_function) and
|
|
[Part number, wiki page](https://en.wikipedia.org/wiki/Part_number) some rules build about the naming
|
|
convention and versioning:
|
|
* C, custom parts, placed in rotator_parts file
|
|
* H, hardware parts, placed in shared file
|
|
* A, assemblies, placed in assemblies file
|
|
* All used part numbers are placed in part-number-list spreadsheet.
|
|
* Start the number from 1000, e.g. C1000-1.
|
|
* Dash -1 (odd), are parts from same family for example M5 screws with same DIN and different lengths.
|
|
* Dash -2 (even), are parts from same family but all features are mirrored.
|
|
* Small changes in the part (fit - aspect), not affect the part number but affected the variant (-n).
|
|
* Big changes in the part or assembly (form and function aspect), affect the part number, make a new one
|
|
and replace or remove the old one.
|
|
* When a part is ready, in the commit message only this part and the message contains the revision of the part and a
|
|
release note about the changes. If needed update the drawing inside the freecad.
|
|
Then commit all sub-assemblies and the main assembly which affected by the part or parts.
|
|
* In order to add a new part take a new part number according to the part number list (spreadsheet).
|
|
* When a part or assembly isn't ready for release, in commit message add WIP, work in progress, write the
|
|
changes must be done, refers to the issue.
|
|
* When all parts and assemblies are ready and working properly, a release is done with tagging the last commit
|
|
and a file with all fabrication files like *.stl, *.step, *.pdf (for drawings), *.dxf (for 2D parts) are generated
|
|
which each file is naming with pn_revN.*
|
|
* Master branch is most times under active development, so expect things to break.
|
|
* Assembly is broken down to specific groups, sub-assemlies. The first priority of assembly levels is to help the designer in
|
|
design process and not in the real assembly. The second priority is to make assemblies that helps in assembly process.
|
|
We never work on very large assemblies, due to limitation in CAD program.
|
|
* Try to use a coordinate system that is fit in the main assembly.
|
|
* Drawing revision does not exist, only part or assembly revision is modified. When a small change is done in drawing for example in text the revision isn't change because the part or assembly isn't change.
