Ajutor flasher cu 8 led-uri

Recommended Posts

Buna seara, am nevoie de ajutor in realizarea unui flasher cu 8 led-uri bazat pe un "joule thief" si un Lm3909."Joule thief"-ul este asigurat de o lampa solara de gradina la care i-am adaugat un mini-montaj realizat cu batranul Lm3909 dar care nu reuseste sa aprinda decat un singur led. Doar cu lampa solara, fara montajul "flasher" se aprind toate cele 8 led-uri, deci energia necesara ar fi.Ceea ce as avea nevoie ar fi o idee, schema sau ceva care sa-mi asigure un boost de energie la iesirea din LM3909 dar fara a folosi alta sursa de alimentare decat cea a lampii solare.
