For me it was reverse engineering an obsolete travel scanner (should have just taken a photo ) and automating a document workflow. Something I knew was possible but impossible for me.

This pulled me into BLE protocols and private APIs and integrating with things directly instead of using 3rd party apps that were bad or limiting.

It's now opened up vibe-coding personal apps in hours, where I simply didn't bother before because I didn't have the time. https://type2fun.net/infinitely-scalable-personal-apps
