<?php
      include 'fusionFunctions.php'; //gives access to fusion brain daemon
      relay(5,1); //turns on relay 5
      relay(7,0); //turns off relay 7
      print getAnalog(2); //prints the analog value of sensor 2
?>

So, for example, I could code a web page with buttons on it like 'Relay 5 - ON' and point it to a script that was, say, "relay7_on.php" and it would turn it on?

I'll PM you so we don't hijack the thread. I'll show you a few neat php tricks that make this easier than you imagine.

There you go. You've got web design, now expand into javascript. From there take on something that looks like javascript... like C# (Best Programming Language Ever, yes I'm biased) or Java (Piece of crap).

It's not to difficult if you go about it how I did. If you can work with wood, you can spread bondo over it and sand to get that plastic-looking finish. There's another thing to throw on your "try" list. haha

I've began to program a stand-alone cross platform application which allows you to control the Fusion Brain across the internet and from a variety of programming languages. Check out this forum post: http://www.mp3car.com/fusion-brain/1...-internet.html

Cant wait to see..... youve been very quiet! What was the name of the 12V - 5V stepdown that you use? Would this one be any good? http://www.current-logic.com/shop/in...roducts_id=190 What I like about it is that it has a total of 70amps. That could power just about everything and then some.

The Mean Well brand converters have been working well for me for over a year. I'm using their 50 watt, 5 volt supply. http://www.jameco.com/webapp/wcs/sto...0001_212549_-1

50 watts is definitely overkill in my project. But those current logic supplies look pretty nice with efficiencies over 95%, high current, and high temperature tolerance. I've never used them so I can't speak on reliability, but if that's the current you're going for, those look pretty good.

Let me ask, the devices I connect will only use what they need? They wont overload anything will they. I estimate I will only use about 30 amps. Just want the extra for future proofing.

Also for you car, you have a dedicated connection? What are you using for it? Company, etc.

Well the devices power consumption will definitely fluctuate a bit. What devices are you powering that are going to eat 30 amps at 5 volts?

Well its a number of them:

1 7 port USB Hub (1 amp)
1 Ethernet Switch (2 amps)
6 KVMP Switches (2.6 amps each)

So its only about 20 amps. With that being said I decided to lower it to a 12V - 5V 30 amp unit. So thats 10 amps to spare.

Let me ask, I am going by the amperage listed on the devices. Is that the max that they can use? Then technically I dont need more then 20 amps?

The USB hub consumption sounds about right assuming you're using every port.

I *HIGHLY* doubt those KVMP switches use 2.6 amps each. Are you basing that number off what it says on the power supply, or does the device state what it requires?
I would double check that with a multimeter. I would be surprised if they even consumed 1 amp. They do next to nothing except power some multiplexing circuit and some LEDs. I bet the LEDs use more power than the rest of the KVMP combined.
But, definitely, do double check before taking my assumption for fact.
