Hi
Playing around with the Bowden AC current detector:
http://ourworld.compuserve.com/homepages/Bill_Bowden/page8.htm#aclatch.gif
but I have had no success with my modification of using a low
resistance (0.02 ohms) sense resistor in place of the coil. As this
resistor is in line with the live feed, it should have a small voltage
drop across it in line with Bill's inductive pickup - but is this the
wrong thing to do?
With no AC current, there is about 1.9V from pin 7 which seems to be in
line with his notes on "no-signal". With an AC load sufficient to give
about 8mV across the resistor, pin 5 still reads 0 volts. Do I have a
bad circuit, or just a bad idea?
