Maplin do a range of 5v regulators which would be suitable, as long as you're not going to be drawing too much current. These are the 2amp versions, but there is a 3amp one as well. They also do some which are designed specifically for automotive use, although I think they're lower current (1amp?) http://www.maplin.co.uk/Module.aspx?ModuleNo=7939 You do also need a couple of capacitors in the system, don't omit them because the output voltage becomes unstable. Also, check the requirements for heat sinks, particularly if you're running the devices anywhere near their rated maximum. Heat-conductive paste (as used on computer heatsinks) is a good idea too. The datasheets (also available from Maplin on free download) should tell you how much current you can safely draw without a heatsink. -- Tony Vincent --- avast! Antivirus: Outbound message clean.
