Nice work there..

What sort of etchant agitation do you use?
I found with smaller bubbles from the bubbler hose my etching is OK now.  
It is still faster at the bottom edge, but that is to be expected .

I really get high quality pcb. One of important tool
is accurate temperature control from my tmpr module.

Now, all other points in home PCB is solved perfectly, only problem
to me is etching uneven! I prepare to build a contant temperature tank, with
fuild in cycling.

By the way, if any body need my tmpr module, you can email me. I will enjoy
my time turn out with some cash. And only if you can handle 110 electricity.
