Tranzystor jest dowolny (np. bc107 lub odpowiednik).
Zasilanie jest prawie dowolne. Układ pracuje prawidłowo od 3V. Napięcie przy którym następuje zniszczenie diody LED w tym układzie to 455V :-) więc jeżeli chodzi o zasilanie to układ jest bardzo elastyczny. W rzeczywistości górne napięcie zasilania jest uwarunkowane napięciem przebicia kolektor-emiter tranzystora (np. w BC107 jest to 45V).

The transistor is desired (e.g.. BC107 or equivalent).
Power is almost arbitrary. The system is working properly on 3V. The voltage at which the LED is destroyed in this system is 455V:-) so as regards the power that the system is very flexible. In fact, the upper voltage is subject to voltage Collector-emitter breakdown transistor (eg. In the BC107 is 45V).
