dear allen,
my first attempt to wind the wire to the ring...see the picture no1 that i attach..
the shape looks just like pic no2 but right now i only can keep it to the same shape closely coz i tape it using selefon tape,if got no tape,the it would not be that close if u get what i mean..so any idea / suggestion for this matter?
and next question is if what im doing is right,how to test it work or not?
thank you
