I find it highly amusing that both of the links you provide use a homebrew
tank. Who did say there is no need to build one ;-).

Thanks for the side note, i hadn't considered that so far ;-)

ST

Another side note: make the tank very narrow, mine is about 2cm, just  
enough to let
the hydrometer float.
Also make the tank higher than it is wide (which i didn't). you add dead  
"safety headroom"
space if you make it wider than high. (but then i have a lot of "strip"  
cutoffs which
fit nicely horizontally now if i need a giant pcb.
