Sounds good.

I dont know if it will help but the bits i have laying arround have come from an old amstrad sterio system (the really big ones). One is from a hitachi VCR thats about 25 years old now. Ive got a sky box here thats not doing anything too. Im just trying to track them all down. I know they are in the loft somewhere. Might take a while to find. I could always drop into maplin i suppose.

Can someone explain version 2 in that link i posted please. I dont understand it. Where does it even get the power from?
