LED Power

This circuit has raised a question in my mind. Where does the power come from, that powers this pulse, power source? (a.k.a. the pulse generator) The reason I ask is because, if indeed the power for this circuit is supplied by a 1.5 volt cell, then it is implied that all of the power is from that cell. Op-amps (In E.C.)are powered from an invisible power source... Is this pulse generator powered in the same mysterious, invisible manner? It appears to be true. I am not posing this question to user Guich. I suppose this answer should come from Igor. / Perhaps it is time to make allowances, for all components that need external power. To give our circuits a more realistic look & action. Such as in this case of an indicated self powered claim. It could be as easy as a configuration setting for the given component, as to it's source of power, in the same way we set other component parameters. Opinions requested.

Love JT circuits. Entered about 10 tonight i want to breadboard. Want to try FET versions too? Check quantstuff.com for lots of JT coolness

I like the idea of manually powered op amps (instead of set voltages) and other components to an extent. In this case the actual current supplied by the pulse is 1mA or less (compared to 10 from the cell and 15 total through the LED) so it's not so much of a worry.

If those numbers seem wrong notice the precharge time of this circuit before the LED glows: I imagine if you waited long enough the capacitor would deplete and the circuit would oscillate.

@UncleRick i placed there a pulsegenerator for simulating a timer-ic
