I changed the cheesy IC sockets they provided to quality ones and =
exchanged the LM324 and CD4066 to LM2902 and 74HC066.
They send me the LM1086 instead of LM317. Which is the one that should =

Normally me too, but in february my start was to send an ordering-email =
to the guy who organized a group buy of parts last year, but never get =
an answer. Then I read that some people send money via paypal and =
haven't got a kit, so I start to search at my standard suppliers here in =
Europe (RS, Farnell, Conrad) - found only 90% of the parts, and cause =
the minimum packages I have to buy oodles of different 1% resistors. =
Then I read about the OZ thing and ...

Just now I saw that there is another group buy - the price difference is =
$10,- maybe $15,- considering the cheap parts. Ok - I think they will =
not get very rich with this work. =20

In principle thanks to the designer(s) of the DIY-WB. I thought 2 years =
about designing an evaulation circuit for WB-Lambda sensor but I'm a =
mechanical engineer; analog in - linearisation - analog out with an =
embedded =B5P that's the maximum what I am able to do. Ion pump cell =
supply with positive and negative current -- uiuiui.=20
