Subject: intercom 9v/12v


Hi all!

I'm looking for an help for this "little" problem:
(Micha, always little problem ;-))
 
I want to connect my 9 volts (actually battery powered) intercom to my
@'s battery (under key switch for avoid empty battery if I forget it
on).
You know @'s voltage is 12v: any idea for reduce it to 9v between + and
- of my intercom (without damage the @'s electric circuit) ?

If you've suggestions or simple electronic circuit please let me know

Thanks
Nicola
