So there it was staring me in the face- I'd been looking for a ferrite toroid to make a joule thief for some time. The old Samsung came right in the end. How did I not spot it before?
Joyously unwrapping the mains lead from it ; I was , like a magpie dazzled by something else on the board. Moving in I stubbed my finger with toroid on the bench and it promptly fell to the concrete floor.
I remembered reading that ferrite was fragile just this morning.....
Boo Hoo
