Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

They represent a significant leap forward in terms of functionality and ease of use, offering a solution to many of the issues that have traditionally plagued servo motors and controllers.

Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.

Animate then does the interpolation between the different shapes, producing the servo positions needed for each frame. He uses an AS3 script to send those positions off to an Arduino.

The CNC-Machine Instructable, created by the folks at CNC World, is fairly straightforward. You take apart a DVD player and then use the case to create a sort of platform for the system.
