Regulated single 1.5V AA Led Flaser Concept

there are different 2N3904 models the ones with 100mA I.F and the ones with 150mA I.F -- in REAL implementation of this circuit you may need to multiple parallel these for a switching transistor or use a more powerful low U.CE type one

PS! this is a simulation experiment - the real circuit and components for a similar output parameters may somewhat or significantly differ of those shown in the fig. !!!

about & how we got ↑there↑ ::

initial circuit
the op amp regulation promises worse results than the transistor regulation on the first figure

Web Buck Remake

src. ::

somehow it did not "work"/simulate too well

experimental/unfinished mod. :: with "pulse skipper" for low loads
/// i have no any idea at this point how one should tune the real circuit into proper operating mode . . .
