I had a concept for the hall effect sensor layout that translated into a straightforward software implementation with no additional sensors, but one additional magnet. My proposed layout is simply drawn up in Inkscape and the analysis written up in LaTeX.

I am excited for this project and hope to contribute more. Once a first functional design emerges I plan to build and test it.

Thank you for the consideration and I hope this helps.

Inital addition of a geometry tester based in blender.

The tester uses blender scripting to report the distance between magnets and sensors, updating it on each new frame of an animation, with the option to output it to a CSV. This can allow for positions of Magnets and Hall effect sensors to be tested, viewing a simulated hall effect strength.

an example of this can be viewed here: https://imgur.com/a/oOc8l2U

I am pretty much new to using GIT etc, so apologies if I do something wrong/not standard practice. Please just tell me what to do and I shall do my best to learn.

Added a README that includes a bunch of inspiration projects, most of which include both 3D designs as well as firmware. Other videos included are a SpaceMouse teardown, and some non-conventional designs.

This is an assembly I was using to decide whether or not to use an off the shelf control stick or produce something that is mostly 3D printable with some basic additional hardware.

The assembly is not complete, and the stick would not function without some modification to the model.

If this was to be considered a viable option I can make any required / suggested modifications and complete the assembly.

This is just a mockup for comment, not a working board. Enclosed copper areas should be filled and connected to appropriate nets.

As proposed https://twitter.com/databasescaling/status/1388295587062243331

The boards in the stack would all be the same but with different parts wired up.

A stack of two boards could provide the two pan degrees of freedom in X and Y. A stack of three boards could provide the twist degree of freedom as well.

The middle board would use the radial pad on the top layer and the rectangular pads on the bottom layer. The top board would use the radial pads on the bottom layer to complete the twist sensor. The bottom board would use the rectangular pads on the top layer to complete the X and Y "pan" sensors.

The boards would be mounted concentrically in the enclosure but bonded to different parts. The enclosure would have to ensure that they remained a small and well specified distance apart.

Dimensions are not properly specified yet but hopefully there will be sufficient space on the top and bottom boards for the supporting circuitry.

Thoughts?
