HiFq Flasher revisited + SCR alternate

somewhat unusual LED-driver that i doubt will startup with 2N2222-s but might with single MJE13005 or with it's higher frequency v.

the following appears to be an in series (or in parallel) self-powering/-delimiting supply for power control -- a concept / feature-research design for . . . !!!

PS! -- it quite likely is not secure to build and use as shown e.g. one must realize the principles and shortcomings here , also extensive additional testing is needed to verify such as secure or not -- there were studied a special situations where the supply failed to lock up / delimit itself -- i haven't collected enough data on it yet !!!
