Thank you Davepar I shall look forward to receiving your order. I am sorry for the delay in posting my progress but you have to have some before you can announce it.
I am pleased to say that I have sitting on my desk the first prototype IRCLONE-MX. It isn't perfect, yet, but all the essentials work. I can upload to it which means it transmits and receives and I can capture key presses with it. I can't successfully download from it yet but I know the general area in which the problem lies. I had a major problem programming the micro-controller over the weekend which necessitated me writing a whole load of software. That is now fixed and working.
The good news is that I don't have to change the PCB layout and all the components work the way they are supposed to and right now I am tired but very happy. I'll be in touch.
