Hi its Roger,
I thought you would be interested in
this ,the coil is not the best but is was at hand ,so I used it.
I have and LCR impedance bridge and on the bridge the coil was 5.7 mH but the Q was 5 , the wire was very thin and I do not think the core was ferrite , lated on I will use a better coil.
Interesting , in fig A the device works like a neon discharge oscillator. In fig A wave form at point A
In fig B, Ch1 wave form is point A and Ch2
wave form is point is B , the coil was one I had
around and its Q was low ,not a
Also when I put one turn of wire around the core and short it ,the wave form at point b reduced but the input current did not seem to notice.
All the best Roger
