Diese Schaltung hab ich aus einer App. (Name:    Schaltungen mit dem timmer 555    oder so)

C1=0,001 Mykrofarad    (ceramic disk)
C2=0,001 Mykrofarad    (ceramic disk)
C3=4,7     Mykrofarad / 25V   (Electrolytic)

Zd1 ( unter R1 ) = 5,6V/ 1W 
Sw1=ON/OFF Switch
Led 1

VR1=VR2=20k Ohm  Vr= Poti

IC1= NE 555 Timer IC 2N4922

R1= 390 Ohm
R2= 680 ---"---
R2= 39 Ohm /1W
R4= 27k Ohm
R5= 47k Ohm
R6= 3,3k Ohm
R7=100 Ohm /1W
