Spintronic Battery (6 V)

Pulling the string to charge this battery is oddly satisfying and takes just a few seconds. My spintronic circuit has been running steadily at exactly 6 V without any fluctuation.

Wasn't sure a pull-string battery would keep a steady 6 V, but it does — no flicker in my spintronic circuit at all. Charging takes a few pulls and the spin voltage stays rock solid after.

Pulled the string back and it held a rock-steady 6 V spin voltage the whole evening while I ran my spintronic circuits. Winding it up takes a few seconds, and honestly the constant output surprised me for a part this small.
