Please, share your story of your own project/site/app built in a single weekend and generating you some positive income. Those stories are the most inspiring part of HN to me and i would like to hear more of them!
I built the original http://www.giftlizard.com in a weekend. Marketing and adding inventory took a ton more time after that.
I also wrote some twitter bots that earned passive income for the last 2 years (not huge but $x,xxx for a weekend's work and it continues to earn). Trick was finding something people wanted and was easily monetizable and constantly updating. They were mostly in the jobs space.
Building an audience that is interested in content I can automatically generate/link to. Figure out related content I can put in that pays too or get some type of commission from from content sources.
I was a bit bored during this weekend and created "Bored Bookworm". http://www.bored-bookworm.com/
It has not yet generated any money, but my brother promised me to buy some book through it. :)
