Electronic Gurus... need a little help
Is there some way to reduce voltage to devices connected to a 12v car battery ? For example, I want to mount a cam in my car but it requires only 9v, is there something I can wire inline to reduce the 12v battery supply? Thanks.

It sounds like you might be looking for a voltage regulator, often referred to as a "v-reg" for short.
Guitarjunkie, you're probably thinking of V = I*R (ohm's law).
Voltage = Current * Resistance.
Another way you could crudely deliver 9V would be to add a resistor inline, but if this is an expensive piece of equipment like a camera, you're going to want a voltage regulator for sure. You might even be able to find one at Radio Shack. How many amps does the 9V device need?

Here's a link to the item I'm trying to duplicate. I missed out on this auction and they don't make them any more so they are really hard to come by.

What wattage/amperage is required? There are many cheap, pre-packaged, universal DC-DC power adapters available, but you need to know how many watts/milliamps the camera needs to find one. And you also need to find a connector that will work for your camera.
This place might have a DCP-77: http://www.iviusa.com/WebList.html

OMG
i must have been smoking crack last night!!!! that's what i get for trying to multi-task
but voltage is E, so i said voltage is current times voltage....hmmm that's the way dave's world was working last night. HAHAHAHAHAHA

Problem solved!!! When I looked at the link Jim posted, I remembered I had bought several plug-in converters similar to those back in the day to install my old Sega Genesis in my van. I just had to figure where I stored them... FOUND THEM!!!! They are Archer universal DC adapters for game players. I bought them from Radio Shack sometime in the early 90's and never used them. Now to figure the polarity and wire it to my battery case! Thanks for the help guys!
