Crimper and pins?

Slippyblade:
Question for you folks that roll your own harnesses.

I've been looking and not finding the info I need here.  I've been using a lot of .1" pin headers lately.  Love em.  But I've been using scavanged wires to make connections.  I'm running out of salvage to scavenge from and will need to start making my own wires.  What is the proper name for those types of connectors?  I'm assuming that it is possible to make those connections on your own, but without knowing the proper name of the pins or the crimper, I'm WILL end up ordering the wrong tool and that's a pointless mistake that costs money.

So, what are they called?  Anybody wanna toss a link at me?

You're looking for a D-Sub crimper

Paul Olson did a decent how to video here:

I still only crimp my own when they're being inserted into some type of connector housing.
Otherwise it's just easier to buy a bunch of jumper wires from pololu, cut them in half, then splice my wire to them.
It doesn't look too bad if you have proper sized heat shrink tubing and the crimp is much better than I can usually acheive.

They also sell "premium" jumper wires that have the square black housing on the ends.

They are commonly called DuPont connectors.  The pins are a pain in the butt even with a good crimper. 

D-sub refers to the end of a VGA or Serial cable, not the kind that uses the .1" pins.

To add a bit more...

These are headers and header connectors. See here.

But they are commonly called DuPont connectors (even though DuPont doesn't make them).

The tool you use to crimp them is usually called a D-Sub crimper, because it crimps D-Subminiature connectors and header connectors. People complain about the price of these, but you can get a cheap ones for less than ten bucks.

What's the application?  Are we talking Arduino or a similar avr or are we talking arcade controls or a hybrid of both?

The reason I ask is because those jumper wires (that's what they are called) for an avr are so cheap you can't make them as cheaply.  Go in ebay and you can usually get 10 or 20 sets of 5 pin jumper wires for well under 5 bucks.
