I've Been Collecting Data Without Realizing It

I keep a spreadsheet of every electronics component I’ve bought. Date, price, what project it was for, whether the project actually worked. I started it to track spending, but the other day I realized: that’s a dataset. A messy, human one, but a dataset.

Same with my synth patches — I’ve got notes on what settings produced what sound. Same with game scores, reading lists, even which soldering tips I reach for most. All of it is data I already have, just sitting there being boring in a spreadsheet.

Data science always sounded like a corporate thing — dashboards for executives, A/B tests for ad clicks. But the tools are the same whether you’re analyzing customer churn or your own solder joint failure rate. And honestly, figuring out that I waste 40% of my component budget on projects I never finish? That’s more useful to me than any corporate dashboard ever would be.

First up: I’m going to visualize my component spending over the last year and see what story it tells. Matplotlib, a CSV export, and an honest look at my impulse-buying habits.

Here’s your nudge: you already have a dataset. A spending log, a workout tracker, a list of every book you didn’t finish. Stop reading about data science and go plot something you actually care about. The tutorials will still be here. Your curiosity might not.
