I decided I better draw this up before I started soldering things together.
This is what I came up with:
I have also attached a PDF of this if you want to get a printed copy.
I'll see how I go over the next couple of days with this but it is not too late to tell me it won't work or suggest some ammendments as feed back to an electronics noob would be much appreciated.
EDIT: Just looked at this again and it seems that C1 is not required where DC voltage is going through IC 2. so leave it out.
