Hi, A few days ago someone of you posted that he had built a power supplay which is able to supply +12V, -12V +5V, -5V from a car power supply (12V). Unfortunatly I deleted this message. But I need such a supply so I would be happy if you post this message again with the URL for the schematics (I think there was a URL) thx, =================================================================== Kraft Bernhard aka.
