Do you have a schematic for the DC step down circuit or a website where I can buy one?

The power converters are on eBay as posted in another thread, no time to look. They're about $8 shipped, maybe less.
When I shut off my ignition, I hard-off. I don't care about the "possible" problems. If my car goes off, so does the computer. I do have a switch that will hold power but that is risky business. My bootup times are about 10 seconds, so turning on is not a problem for me.

I think this was posted before: http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT but it's about $15 shipped. Was this the one or is it a different one?Originally Posted by colin
That's the one, but it only came to about $8 shipped. To Canada.

Guys you're all going overboard on the "step down converter." It's not hard. 5 volt linear regulator, i.e.

They come up to 5 amp capacity. Simple to hook up, 3 wires (+12 in, +5 out, ground). Add a cap before and after and you're golden. It's all explained in the datasheet:

Yet you link to a 1 amp version. LOL
Also with a 3A or 5A version you will need a rather large heatsink.
So it's better to just buy a prebuilt regulator.
My 2007 Yukon XL setup. http://www.mp3car.com/vbulletin/show...64-5000-a.html
The problem with converting 12v to 5v at 3A is heat.
Think of it like this, you're dropping 7 volts to get 3 amps. That's gonna be HOT.

if you used a little pricier switching type regulator you can eliminate most of that heat, can't you?
That's exactly what was used...
theshadow27 proposed a linear regulator instead.
