Now we will begin the mechanical design for the controller. This will include a CAD design of the Arduino/breadboard assembly as well as a physical prototype. The CAD work will utilize two new key functions including importing parts from external files as well as inserting parts directly into an assembly from McMaster-Carr.
This video shows the exploded view of the controller assembly along with all of the parts needed to create the assembly.
Copy the engineering notebook template into your engineering notebook then work through the procedure below, answering questions in the ENET as you go along.
3.8.3 - Controller Mechanical Design (ENET)
In this section you will build an assembly of the Arduino. Follow along with the video to begin the import and assembly process.
Open Fusion 360 on the computer.
In the Data panel, create a Folder in your FE-X Fusion 360 project called "Game Controller Project"
Download the following f3d files.
Arduino UNO Acrylic Case Final_bottom v4.f3d
Arduino UNO Acrylic Case Final_top v3.f3d
Upload these items into your folder.
Create an Assembly File called "Controller_Assembly_Lastname_Firstname" and Save it
Next we will begin assembly of the controller as well as inserting parts directly from McMaster.
The following hardware should be inserted from McMaster (McMasterInsert.mp4)
94639A702_Off-White Nylon Unthreaded Spacer 1/8" length (Qty. 4)
91099A167_Passivated 18-8 Stainless Steel Phillips Flat Head Screw 4-40 Thread, 1/2" (Qty. 4)
90480A005_Low-Strength Steel Hex Nut 4-40 (Qty. 8)
94639A658_Off-White Nylon Unthreaded Spacer 9/16" length (Qty. 4)
90272A114_Zinc-Plated Steel Pan Head Phillips Screw4-40 7/8" Long (Qty. 4)
Now use a pair of calipers and a data sheet (dts02-2586188.pdf) to CAD your own Version of the Push Button
The legs of the push button can be straight like the image below.
Now add the buttons to the full assembly. Position them as depicted in the image to the right:
Note that you will need to use a Joint Offset to align the pushbutton switches on the breadboard. This can be seen in the images below:
Dont forget to post all of your work to your engineering notebook.
