Anyone have any experience converting a TV into an oscilloscope?
I have found the deflection coils and have tested them but I'm not really
sure where to go from there. I know that for the horizontal I need a
trigger(a sawtooth) but I'm not sure at what currents and voltages I
need(with my variac hooked directly to it about 3 volts gives almost full
deflection(which I measured about 0.05A).. but I'm not sure if thats right.)
Is it simply a matter of putting an variable gain opamp on the vertical and
a variable sawtooth on the horizontal? Seems like it would be kinda hard to
measure frequency that way since I'd have to convert the resistance of the
sawtooth into frequency.
Any ideas?
Thanks,
AD
