I started using python scripts to invest in the stock market when nobody did that and earned some money.

I modified a digital hygrometer and thermometer so I can register the temperature cycles inside and outside my house. I also do it with my plants in the garden.

I reverse engineer all my GPS(garmin) clocks so I can store or upload GPS coordinates and tracks without some stupid and inefficient web app that the manufacturer controls for me.

I reverse engineered and hacked the routers from old Internet providers and posted the instructions on the internet for others to replicate.

I scan and OCR and process every single ticket and receipt... Do the same with books.

I also have friends that do the same kind of things so it is kinda normal to do those things all the time.
