Kcarp:
Controllable Power Outlet - SparkFun ElectronicsI found this tutorial.
I think this is what I need.
The tutorial tells you all you need to get them to work, I.E. a little transistor drive circuit, but I really hate the idea of a clunky relay to switch a heating element (ask you friend about a solid state version or to even look at a cross over zero switch at least)
all the best
