Reicht aus, um sich nachts im Badezimmer gut zu orientieren.

100 Wicklungen 0,3 mm Kupferlackdraht
2 superhelle 3 mm LED´s gegeneinander verschaltet
ein Käppchen von einer Haarfestigerflasche
etwas Heißkleber
die vorhandene elektrische Zahnbürste mit QI Ladung

Nachdem die LED´s nicht lange gehalten haben, habe ich mal nachgemessen. Der Qi Lader schwingt sinusförmig mit einer Frequenz von ca. 21650 Hz bei einer Vss von ca. 20 Volt. Das Zufügen eines 340 Ohm Widerstandes hat jetzt die Lebensdauer der Led´s wesentlich gesteigert.
:) :)

Weniger Windungen ? Rv ist sowieso ein Muss.
