Awesome, this is a much better hardware build than I ever had!
Thank you for sharing. The readme is getting pretty extensive at this point. We should strive for a concise readme to allow people to quickly see what this is about.
How about we
- move the construction instructions to a separate file, i.e.
CONSTRUCTING.md - From
README.md, we only give short teasers for the end product(s) and links to the construction instructions.
That also allows us to become more extensive in the instructions and show all your images, ideally in a step-by-step manner. I can do this in a follow-up PR.
General comments:
- git doesn't like large binary files. Please crop the images where suitable, and scale down images that don't need that much detail.
- Consider enumerating your images from beginning of construction to final product
As always, I'm happy to implement any of my suggestions myself ;)

| If you make it on an Arduino shield, you can 3D print [this case](https://grabcad.com/library/glass2glass-arduino-mega-case-1) for it and do something like this: |

Nice! Should we give more details to the readers about how to construct this? I'm not sure whether the images are sufficient for e.g. beginners.

The case is just two parts, and I provided the full SolidWorks assembly which shows how all of the hardware is put together (no circuit on the protoboard though), so to me that's ok for the hardware. If they have access to a 3D printer they probably won't have trouble with threaded inserts.
The other part would be explaining how to solder the protoboard, and I feel like that should also be prerequisite knowledge if they're going through with using the case. Only other thing I might add would be a comment on the wire gauge/type and length, I picked something thick but it looks like in your paper you used really thin wires

Sorry for being unclear: I agree that 3D printing is covered by SolidWorks. I was more concerned with the exact circuit you put together. But now, when looking at your photos of the front and back of the shield, I think that these are absolutely sufficient. In particular when embedded into the explanatory text.

okay, thanks for the clarification. I'll respond to the other points when I get the chance!

Can you state what you're using in the images? Arduino shield, I guess? Which one specifically?
