running a 4W LED from a 1 volt source by pulsing it with back emf. press button to start
the oscillator should work, I want to try it out. the transistor base current comes through the secondary winding, turning the transistor on. current flows through the primary winding which builds more current through the secondary back into the base, forcing the Transistor on harder and harder until Vbe gets too low, switching it off.
my theory there is that the resulting back emf spike should pull the voltage on the emitter negative enough to hit the high Vf of the LED, switching the LED on, and the current sink of the primary will be enough to power the LED
or it will just blow up
