Are you working on an Arduino or robotics project using servo motors where the wires aren't long enough? Then you need servo extensions. You can buy servo extensions at many hobby stores and online. They are designed for a particular brand of servo and have specific end connectors that usually don't fit my needs.
When working with DIY robotics projects we usually need some kind of custom servo extension so I'm often making up a special connector. I am also preparing for a Soldering Workshop at the CCCKC Hacker Space so this Instructable will help serve that purpose too.
Another gratuitous plug for CCCKC.
Building servo extensions are not breakthrough technology for an Instructable but this might help someone pick up a few tips.

Solder and soldering iron.
Helping hands
Clippers, saw and small vice.
Wire strippers
Heat gun or lighter
Servo wire
Male and Female connection headers
Shrink tubing
Use a low wattage soldering iron. 15W to 30W works best for me.
Solder - Some solder may contain lead so don't put it in your mouth (I saw someone do that once).
It is possible to use individual stranded wires but I like to use the 24 awg three conductor servo wire I bought from Servo City. It comes with the correct layout of the wires, red for + power connection, black for ground, and white (or yellow) for the signal wire.

The servo I'm using has circuitry inside to control its motor and can work directly from the Arduino. If you are using regular DC motors then you do need to have a motor driver chip or other devices like the motor shield to operate them.

thank you for the help. I was wondering because i wanted to make a cheap version of the SERVB and i wanted to know what I needed. My version would cost only $33.50
