Can anyone please help me to find a circuit for Voltage to Frequency Converter using BJT and 555 Timer IC?

The basic idea is to use the pin 5. Apply a variable voltage to it to modify the frequency of the bi-stable oscillation.
Check for "Police Siren Using 555", a circuit using the principle (and two 555).
