Just had a quick look at the diagram. It was posted before my time, however it looks like it should work in theory, but the way it is set up, I'm unsure how long the individual components might last. There are plenty of other "Timer" switching circuits available that would be more robust. If you're buying your components at Jaycar (or most other electronic components stores) they should be able to help you get the right one for the job you're doing.
