My book "Mastering Modern Payments: Using Stripe with Rails" continues to sell well, in the $2k range per month. It's not exactly passive, though, as I write blog posts and develop other related content in the same theme. https://www.petekeen.net/mastering-modern-payments
My iOS app that teaches you what a tesseract is and lets you manipulate it in 3D and 4D. https://itunes.apple.com/us/app/the-fourth-dimension/id50420... It blows my mind that people still find out about this app and happily buy it every day even though it occupies such a small geeky niche.
I created and sold Stickonspy ( http://stickonspy.com ) just after mid last year. The initial month I launched it did pretty well as the NSA news was still a pretty big deal. All in all it's made me I'd say my time - which was evenings after work - investment was around 3-4 days initially and then fulfilling orders is simply writing a customers address and posting the stickers - which if the demand was bigger I'd pro…
I had created http://notationtraining.com in 2010 when I was learning how to play piano. I did update this project few times, but otherwise it is completely on its own. It makes only about 300 USD/month but I am quite happy with it as I am not doing anything to promote it or anything else.
Income is often called passive but essentially there is always something you need to do, monitor, improve or change in order to keep cash flow steady. If you don't, your income will decrease over time until reaching zero. It is surely easier to maintain "passive income" than to start from scratch.

I've got a job where i do almost nothing. It's my passive income.

Tips:
- I agree with cdaven. Good content is better than SEO, but you only take the fruits 1-2 years later. Use your expertise. It is much easier/faster/more rewarding if you blog about something you are an expert.
- Adsense is ugly but is the fastest way to monetise a blog. I was making 15€/month before adsense and now I have slightly less traffic. Text ads or images ads? If you have an text intensive blog go for image ads and for an image intensive blog go for text ads.
