Joule thief laser

NettetMany of you are probably aware of the "joule thief" circuit. If you aren't, it's a very simple voltage booster that is normally used to power an LED off of a mostly dead AA battery, but it can be used for other applications where a voltage boost is needed. One such application is charging a battery off of a battery with a smaller volatge rating.
