Mixing water and electricity is extremely risky and potentially lethal, yet that's exactly what I did with the Scariac. In its simplest form, the Scariac is just a glorified version of two wires in a bucket of water, but it's actually one of the cheapest power controllers you can make.
BUD (Block Update Detector) switches can essentially take the place of a regular switch like a lever or a button, but instead of having a "usable" function like pressing the button or flipping the lever, BUD switches trigger when a block next to a piston changes states.

But to get to the stars, we need to start with the basics.

You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.
In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it mind-boggling! The world of microcontrollers is fascinating, engaging, and an awesome hobby; it never gets boring. I'll be focusing more on I/O and analog based microcontrollers, such as those running Arduino, and using Atmel chips as examples (these are most commonly available, and easy to program).
