Just saw off the left hand end (with the supply bypassing).

I suppose the "art" is in making it relatively easy to build but minimizing the space taken.

If you're manufacturing thousands then every cent counts, every hole you can eliminate in the PCB is a fist full of dollars, but one off homebrew you can be one hell of a lot more relaxed about components; they are a tiny fraction of the notional cost in time putting it together, and apart from scrounge, most bits are so cheap they are effectively free.  I have built some micro-miniature stuff for animal tracking (pre SMD), but if you don't gotta, then don't make life any harder than it needs be.
If you say theory and practice don't agree you haven't applied enough theory.

And now, for something different - "Manhattan style" construction.  The lands are small bits of PCB glued down to the ground plane.  This happens to be a Noisy Cricket amp, similar to the Ruby, but the technique is suitable for construction of circuits up into the VHF range.



This is a very simple and direct method and even allows the use of any old bits of PCB that happen to be handy.
