hi all!
i wanted to use a 555 circuit for flashing 24V bulb, i had desined the circuit! for 12V first and it works fine , now i added a bridge diode rectifier and a zener to alter my input source to be 24Vac , after rectification and using a 12v zener the circuit doesnt flash , its On all the time ! plz can you check the schematics
in the working circuit taht uses 12Vdc there is no zener , now i added the zener as shown and the ac 24 v are rectified before that !
