Me too! I have never used airtable before but have heard of it. I needed an inventory system but I wasn't satisfied with the options I found so I created my own. Right now it is rudimentary but it can import BoM, export to CSV, "build" BoM's (auto-deduct from inventory), octopart API integration for grabbing component info/specs, and all of this compiled to single binary for lightweight selfhosting.
I don't have any experience with Airtable, but I do have experience with Retable. If you're looking for an inventory management system, Retable offers customizable templates for various types of inventory management, including product inventory, asset management, and more. Let me know what your specific needs are, and I can help you find the best solution with Retable.
Interesting, I have always visualized tangent differently. A line perpendicular to the X axis that stops at the intersection with the extension of the radius line.
I also always used the perpendicular to x-axis version, but I like this version better bcs the tangent tangents in the point of interrest, plus cotangent and tangent are colinear
