I would like to make a simple 2 axis CNC machine to create gears. One stepper motor could spin the gear, and the other could move a drill bit in a single axis. On ebay, I can find double h bridge controllers for less than $10. For example: [http://imgur.com/XBEww](https://imgur.com/XBEww)

Now, if I were to buy two of these, and two stepper motors, and a power supply, is this all that's necessary (electric wise) to build a gear maker? I already have an arduino and a computer. For the power supply, can I just use a simple power supply that turns a home power supply into something that looks like my car's cigarette lighter?
