Hi all
If someone want to change the frequency preselected by me which is between 50 and 80 khz
you can use a variable capacitor in parallel with your coil and following your calculation of the inductance of the coil
see here
use this website to calculate the values of C and L variable uH
or this
FOR JUMPERs
J1-J2 = battery 9V
J4-J5 = LED1
J6-J7 = LED 2
J8-J9 = Sound
J10-J11= Coil Rx
