Hi Ronv, A bit of feedback:
NFET WIRE SIG GEN.
Test on the bench with 2Xseries 15ohm resistors instead of WIRE. And 2X parallel Schottkys instead of suggested diode, to be
ordered soon. = even Square at D-pin, NFET cool, tot current Circuit + Resistors 200mA, Diodes cool, Resistors hot.
Test with Long WIRE 27ohm = only bottom of square wave at D-pin visible, NFET tepid, Tot circuit + WIRE 100mA, Diodes cool, WIRE cool.
COIL CIRCUIT, with long WIRE +NFET SIG GEN. COIL 100mm above WIRE.
At Circuit output 100mV DC (Bit low I had hoped for up to 5V)
Using a spare COIL simply connected to Oscilloscope, COIL 100mm above WIRE = 50mV
So I'll do more tests, and check all of the COILs and Circuits.
Cheers.
