Subject: R: intercom 9v/12v
Ciao Nicola
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) ?
[Lorenzo e Chiara Marsigli] I did this on my Fiat Panda (eh eh eh ) in 1992 to connect a CD player to car battery (12V). I purchased in a electronic stuff shop a small transformer (11x6x4 cm approx, including a winglet alu base for heating) with 12v fuse protected input and multiple outputs (from 1.5 to 9 v) set by a plastic screw on the transformer front.
I forgot the price but since I belong to Beppe's school, it had to be very low :)).
I think you can also build one on your own using a car-cigarette-lighter transformer: you know what I mean?
[Lorenzo e Chiara Marsigli] it shouldn't be difficult to put it somewhere in @
Ciao da Lorenzo & Chiara & Francesco
