HI. I'm planning to construct this ICL based ammeter : http://electronics-diy.com/ICL7107_digital_ammeter.php where it is stated that "the 0.01 Ohm resistor should be made out of 1.5mm thick / 5cm long copper wire". I think this is an error since someone needs much much longer 1.5mm thick copper wire to get 0.01 ohm . Don't you?
