hi sleeper(why the hell you choose that name , you seem to work all
day :) )
first good luck for finishing your adc board.
and starting to debug your amplifier board !
and second , i liked you're idea of trying the tiny avr with 1 pole
filter .you're on the right direction to the $100 machine !
bye man !
