I don't have any cores - unknown or known.  I would like to buy what I need
but don't know where to start (seems they come in a wide array of shapes,
sizes, types & materials).  I've used the RF chokes (J.W. Miller) from
DigiKey but would like to know how to wind my own.  The RLC circuit for
checking will be useful though.  Thanks Peter.

I'm aware of this circuit but get the impression it doesn't blink.  I'd like
a blinking LED.  Thanks.
