i have try to build this esr meter on my bread board but i have a problem,
the link is http://electronics-diy.com/electronic_schematic.php?id=950
for note i can't find a resistor 1% for 22 ohm for R10 and R12... i just try to 22 ohm that i can get (red, red, gold, gold) and i also try to use 4R7 both not 1% resistor..
i don't know exactly the problem but for the meter i using a small vu meter and the scale needle didn't move directly so far to 0 scale.. please someone that ever build esr meter like this help me...
