The performance factor vs. torque vs. DOFs is the most silly thing as a licensed mechanical engineer I have ever seen. And I was around for Kony 2012.

em0shon Ask HN: How do you document your hardware projects?

At work. I think it’s not very good most of the time.

em0shon Ask HN: How do you document your hardware projects?

Mechanical Engineer here - this is the million dollar question.

We currently use antiquated systems, or bad software based on antiquated systems.

My approach - don’t rely on software. It’s a mentality, not a software. Your CAD should be organized in a future proof structure. Your analysis should reference the hardware by diagram. You should be able to easily find the analysis with nothing more than a hunch. Your drawings should be organized and the numbering should make sense. Create a part numbering schema that gives some information more than just the part number.

Ask yourself every day - if someone asks me where the work I did today is, would I be able to quickly find it?

em0shon Is this Duplo train track under too much tension?

Hello hello! Licensed Mechanical Engineer here. Not to be pedantic, but the track wouldn't be in "tension". It would be in bending (a combination of tension and compression).

Happy to elaborate further if it is valuable to the discourse!
