I'm currently working on a project that has 1 component (a dc water pump) that requires +12V. I'd like to use the current +5V supply the rest of the project uses however I'm not exactly sure how to get up to 12V. This is all a bit new to me so I checked out the DC-DC wikipedia entry where I read up on step-up converters which seems to be what I'm looking for. If so, can anyone point me in the right direction as to what exactly I need in order to build one? Or is there a better option available such as a simple/cheap IC?
