To keep my wife happy in her gardening, I have put together a PICAXE-based watering system controller that might be of some interest. The system has been dry-tested but, since our morning temperatures here in Colorado are still below freezing, I will have to wait for a month or so to actually water something!
Have a look and let me know what you think.
