## Introduction: Wave Plotter

• We were asked to provide a sound wave protester. Angles: 0, 90, 180, 270, 360 °.
Some definitions you may want to know:

The principle of superposition: when it changes

Calculate wavelength, time, and frequency using the following sine: wavelength = 2pi (m) time = 1 / frequency = 1 / 2pi

Sound Wave plotter

## Step 1: Fabrication

• First, you need to use the lab machines to fabricate parts. The machines we used are a 3D Printer and a CNC Machine. Here are the parts and their diameters

## Step 2: The Arm

• This picture shows the arm of the machine. You will need to use solid works to design it and a 3D Printer to make it

## Step 3: Fitting

• Next up, after designing the arm you will need to start making the fitting. You will need to follow the dimensions

## Step 4: Pen Holder Handle

• And for the third part, you will need to make the pen holder handle

## Step 5: Pen Holder

• After that, you will need to design the pen holder using solid works and 3D printer to print it it

## Step 6: The Plate or the Base of the Machine

• Next, you will need to design the base with the giving dimensions. and save file dxf

## Step 7: The Rotary

• Finally, you will need to design the rotary or the disk and 3D printer print it

How to Bild it?

## Step 9: Final Prototype

• this was our final prototype result which was success
