It means kinda little machine. '-illa', as I understand it is a sort of cutsie diminutive suffix. Máquina is the word for machine, so I'm sure you can see what's happening here.
So basically. I write a Spanish word, say something about it and if you like it, or you are curious, you phone me up to hear it. If I don't answer, leave a message and I'll call you back. Easy.
