I have been working on a PCB design which I think is pretty much finished for fabrication. Because it is a double layer PCB
I was able to create some larger copper areas and make it a bit more compact than with perf as I am not stuck to a 0.1"grid.
the maximum size that would fit is 100x50mm or at least the 50mm is fixed. However the cheapest boards are 100x100mm
so I had some spare space. I thought about creating some small boards for a simple LM317/LM337 supply which can always
be useful but I also need some busboards. I can't fit a lot of connectors on such a small size but I wil have 10 of them so I
added some space for screw terminals to link them together. The reason it is upside down is because I cheated a bit to get the
maximum amount of board space. The demo version of eagle I am using allows a max size of ±100x85mm however I noticed
that this only seems to count for components. The boards can be larger and you can still add silkscreen, traces etc. just no
components. So I used this 'free' space for the connectors which don't have the solder pads close to the edge.

also, the fancy gold plated headers I'll be using for the connectors have arrived. Cool
