Unless you're well-versed in electronics construction techniques, and know about star grounding and other EMC techniques, you have little chance of getting a home-made switcher working reliably. But if you are conversant with these techniques, head on over to Linear Technology:
Linear Technology - Linear Home Page
And National Semiconductor:
Design Resources Including Online Design Tools, App Notes, Eval Boards, and Software from National Semiconductor
And do a search for 'switch mode', and you'll find lots of data sheets and application notes with circuit diagrams for switch-mode supplies of all sorts.
