    Please, please, please - Don't Shoot Me!

    I have been reading your boards for over a month - what a ton of great information! Although I have tried to get the answer to my question by "searching" my fingers off - I figured I'll try to ask it hopefully without getting flammed!

    I currently have an 8" TFT monitor installed in my Park Avenue, have a Treo 650, and use an SD card Presenter-to-Go system to duplicate my Treo screen onto the monitor. Works GREAT, but I need the SD card slot available for GPS, so I am going the carputer route.

    I have an HP-E40 on order from Ebay, was planning to just use an inverter. But after reading your boards, installing one of your power supplies or a controller is appealing to me. But, after reviewing the installation diagrams for weeks, I still can't figure if I can do this "easily" or not. I am a computer semi-novice - I can replace hard drives and memory on anything. But, I have never worked with an individual mother board, which the diagrams refer to. I also have self installed a bluetooth handsfree kit in my car, so I have the avaiabale wiring for the battery and ignition already set. I also have Windows XP and a bluetooth mouse ready to install to my new system.

    My question is, to install one of the power systems (or the mini controller), is it as easy as "just" taking off the CPU case cover, connecting two or so wires to the motherboard and power switch, replace my cover, place my new power board in a safe place next to my CPU (I don't plan on an enclosure), connect the battery and ignition wires to the new board, and I am done??? I'm sure I can connect a couple of wires inside of my system, and have the wires stick out of my CPU case cover. My other question is that the new CPU will have an HP motherboard, so how do I know where to connect the wires to? The diagrams on this site seem to reference a specific board, and I'm sure when I open my case, I'll have no idea what I'm looking at!

    But does it require more than just the few connections I "thinK" I see on the installation diagrams? If it's just this easy, I can install this in my trunk in 15 minutes - but it seems almost too easy.

    I searched and searched for a topic as "easy install", and found nothing. Any help is grealy appreciated!!! Thanks!

    Most of the power supplies have a plug on them that you plug into the motherboard. It replaces the one from the power supply you plug into the wall. Shouldn't be a problem for you if you know how to wire the ignition and the constant "on" power.

    The opus connects directly to the mini-ITX....with a connector
    There are 3 wires coming from the opus, these need to be connected to the battery, ign, and ground. this is the only "hard" part. The other end is all connectors, and it is painfully obvious to connect.
    The install instructions for the OPUS are fairly clear and can be found in the description of the unit in the MP3car store.

    It really isn't that hard.

    My experience:
    1. Make sure you are connected directly to the battery with a fuse, as close as possible to the battery.
    2. Make sure the green/white wire from the opus is in the right place and on the right pins of the motherboard. on a mini, green is pin #6, White is #8, if you reverse those, the opus will indicate it with a double flash of the LED indicator (in the manual).

    I wired everything (temporarily) to check it first. THe opus has a light that indicates faults or problems. My only issue has been with an XM cable. Everything has been fairly easy to "figure out".

    Good Luck.

    Oh Well......

    I just posted this under the classified section. Guess it just ain't that easy..........



    Wanted - On/Off Remote Switch for HP E-PC 40

    OK - Just received my HP E-PC40, and there ain't no way I can see how to add an Opus type system. I wanted to buy one, but the motherboard on this HP doesn't look like anything on the diagrams.

    After opening it up, I don't even see where to connect anything for the on/off switch. So, I'm looking for a pre-made, "easy" to install remote switch.

    OR, I live in the Los Angeles area. Anyone interested in installing an Opus system to my E-PC 40 for a small fee? I have the battery and ignition switch wires all ready to go - but I don't think I can screw around with this HP unit.

    Thanks.

    Where is the power switch on the E-PC40 case? Where do the wires from the power switch run to on the motherboard?

    Post some pics.

    Well, a simple solution, but not the best. Install a DC to AC converter. Before the DC Converter add a relay, put a switch to control the relay on the dash, then set the computer to automatically start up after a power loss.

    The correct solution is to wire up the power and reset buttons to a switch on the dash using relays in the computer (those long wire runs scare me, I'm worried noise will get to them) I'm going to use a piece of CAT5 to run my control wires in my car.
