Here's a handy prototyping PCB for larger sized projects
Designing a circuit is one thing; making it is another. Here's a well thought-out PCB from Sure-electronics for those larger projects.
It borrows a similar layout to standard "plug-in" breadboards, so moving from temporary prototype to permanent circuit is relatively easy. Here's the stats:
Dimensions: 4.7 (inch) x 4.1 (inch) x 0.062 (inch)
Weight: 40g (1.4oz)
Hole pitch: 2.54mm (0.1"), 1160 holes total
