Ask HN: Do You Maintain a Hobby Dataset?

I'm looking for inspiration and would love to hear about the datasets and how you're using those datasets in your hobby applications.

My personal data set I am building is a single dataset of all SVG brand logos and colour palettes for as many companies as I can scrape. I'm at about 8k now and not doing anything with it except posting it on huggingface and also feeling a bit smug that I have all this info.

So let's see what you're working on.
