Most of my income currently comes from:

1) ~45% - Two hand-selected ads on a major developer website. These were individual deals with the companies placing the ad.

2) ~5% - Ad network ads on two websites.

3) ~45% - Rental income from my house on AirBnB.

I wish I could say that these were clever projects or startups, but I haven't yet found a "traditional" software side project that makes money. I have one that's been running for a little over a year, although I haven't figured out how I want to actually charge for it. People are just using it on a free tier right now.
