    Matt Eargle pays a visit to Ben in Madison so that they can work together on a Zen robot garden using CNC parts.  The build will use a handheld controller, a stepper motor, and a 3D printed Zen garden rake that will draw designs.  A typical Zen garden rake is a flat piece usually made of wood with four large tines coming out of it. The one they print will hook up to the servo and use the mounting points on the servo to make an actuator for the rack and pinion vertical Z.  Felix and Karen help Matt program the code for the Arduino shield and board using the Arduino IDE.
