'''''WARNING''''': This is a potentially risky project. If not built right, you may damage the device, your equipment or harm yourself. '''DO NOT''' follow these instruction or use anything on this website unless you are willing and able to assume all risk and liability. '''Alteeve's Niche!''' does it's best to mitigate risk and reduce the chances of ill effects, but does not guarantee this information to be free from defects, omissions and mistakes.

Now then, let's begin.

= Updates =

'''May 15, 2010''': Updated the minor version to '''v1.1.4.1'''. This version adds 330ohm resistors to the node feed lines to make it safer to draw the signal directly from the PSU.

Building your own Node Assassin is relatively simple, but it will require a little patience and precision as there are a lot of joints that will need to be soldered. Some things to keep in mind:

* Before soldering each joint, be sure that you've accounted for all wires that are to go into that joint. Trying to solder in an additional wire after the joint is already made is tricky and increases the chance of damaging components and wires already soldered into the joint.
* Think about what order you want to solder in joints. Generally speaking, it is easier to start in the center of the board and then work outward. Add large components, like the extended length 2.54mm pitch pins, only when you need to so that they won't be in your way.
* Clean your solder tip after each joint.
* Use the minimal amount of solder needed to get a complete joint and apply the heat for the shortest time possible.
* Use a [http://en.wikipedia.org/wiki/Helping_hand_%28tool%29 Helping Hand] and a good light.
* Use a fan to suck the solder fumes away from you while working.
* Have a good pair of small needle nose pliers, edge cutters and wire strippers available. If you don't have a wire stripper small enough for wire-wrap wire, practice using your edge cutters to strip the wire.
* BE PATIENT! If this is your first project, you will make mistakes. That's ok, it's the best way to learn! Be sure to have some spare parts around in case you break something. Common parts to break when you are a beginner are resistors, LEDs (specially melting them), diodes and similar fine components. Getting frustrated will just cause you to ruin your project. Believe me, I speak from experience!

|style="vertical-align:bottom;"|The Node Assassin itself is built to piggy-back on an [[Arduino]] and a [[network shield]]. If you already have these, you only need the parts for the Node Assassin itself. If not, then you will need to full kit. Any company that sells Arduino's will most likely carry all the other parts you will need. If you are having trouble sourcing the parts, we sell Node Assassin kits.

This is a complete parts list needed to build the 4-port Node Assassin
described in the files in this directory. Many parts can be substituted if you
are unable to find the exact part mentioned. If you replace a part, please
ensure that it is electrically and mechanically compatible.

== Node Cables ==

When creating the node cables, you may want to get a longer length of black wire as you will use extra to "fan out" from the node-end of the cable when connecting the two extra connectors.

Here is a block diagram of the wires you will need to make for each node:

You will need to make custom cables with pass through connectors to properly use Node Assassin. The only real requirement is that the connector attaching to the Node Assassin be 1x4 wide, 2.54 pitch female connector. Personally, I like to run a common ground to the power button connector and then fan it out to the other two connectors. Each distal connector needs to have a male pass-through connector so that you can still plug in the case cables.

{|
|-
|[[Image:na_v1.1.4_protoshield_variant_cable_01.jpg|thumb|800px|left|Example cable made using off-the-shelf parts.]]
|}

Note that if your motherboard uses the three-pin wide header for the power LED, just use a knife tip to swap out the connector on the NA cable with the chassis cable.

If you do not care about connecting the node's chassis' front panel connectors, you can forgo adding the somewhat tricky male pass-through pins.

= Build Images =

If you want to download all the images, [[XCF]] and [[ce3]] files plus the [[BSchv3]] program as one compressed file, click here:

I found it very useful to use an image viewer, like the free [[GeeQie]], that could switch images via the mouse wheel. This allows you to rapidly compare different layers with the image of the board staying static on your screen.
