can anyone help me with a simple circuit for charging a capacitor to
24 v from a pp3 9v battery ?
i can solder an read circuits buts thats it...........something i
could make on a breadboard / stripboard ? it would need to have an led
illuminate when the cap is charged

not sure how many uf cap would be

I'm not sure how suitable a blocking oscilator would be :)
