rotary car phone

Use an old phone in a car.

Wouldn't it be fun to use an old "Ma Bell" or candlestick phone in a car? My idea adapts a modern cell phone and cigarette lighter jack to power a rotary phone. Use a bunch of logic gates or a BasicStamp to interpret the rotary pulse and control the ringer. Solder the digital controls to the buttons of a used cell phone. To be safe (and to make a lot of fun noises), use a relay and resistor for each button on the phone. Power the POTS phone with a modified inverter. The program or logic set-up would have to provide for sending and ending, of course. This idea probably wouldn't work well with the recent PC-like generation of cell phones. I would love to be driving down the road and hear a real bell ring. My passenger would answer and say, "Sir, you're wanted on the ether."
