Homebrew PCBs

I agree on the space. If you put the ground too close to pads it can make  
soldering harder, as it easily bridges the gap. I think i've 0.3mm default  
in my software, which is too close.

On the etching side i must say it worked rather well each time. Faster,  
and more even i think. Seems the uniform width lines make for a even etch,  
and the small area for speed.
