blog.makezine.com When you think - "DIY electronics", one of the first images that likely comes to mind is a bunch of parts and wire soldered to a standard piece of perforated circuit board - and that makes sense. Perfboard is super-versatile - essentially it's just a grid of potential solder-point connections. You can trim it down to just the size you need - or leave extra space for future enhancements ... or revisions, if need be.
