Since this thread didn't specify that the recurring income has to come solely from technology, I make $400-$1k/mo DJing. Technically it's work because it's not passive, but it is recurring and it is a hobby that requires little to no work - I have a LOT of fun doing it and it pays well by the hour. I'm only posting this because I think it's important to also point out that you can turn hobbies into passive, recurring income and that is a surefire way to getting the most out of your passive income.
