Stripboard can be a wonderful thing, but it can be improved...
Here we have a 50mm square slab of board with thin traces connecting the pads horizontally on the top layer. The trace can be easily cut with a couple of drags of a stanley knife, meaning there's no need to take out a whole hole to make a break in the track. Result - less wasted space, tighter builds.
19 x 0.9mm inner holes across, 17 top to bottom. Then there are another two rows, one top, one bottom, which are 1.1mm and aren't joined with a trace. These are designed to take pot pins. How cool is that?
Chop them down into bite-sized chunks for multiple use.
