15. System Integration
Goals
Individual Assignment:
-[x] Design and document the system integration for your final project
Tools Used
- Pureref - An amazing program for gathering images into a big moodboard
- Concepts - My goto sketching app on the ipad
- Fusion 360 - 3D CAD/CAM software from autodesk
- Zed
- Blender - Free and opensource 3D software that can be used for anything from sculpting to animation and much more.
TLDR; Nice images
Individual Project
1. BOM
| Process | Name | QTY | Description | Link |
|---|---|---|---|---|
| CNC | Top Cover | 1 | The main sufrace on the product, this covers the electronics and is the key touch point of the product. | Local timber supplier |
| Casting | Case | 1 | The body of the product is cast in Jesmonite in a nice contrasting colour to the wood top | Link |
| Lasercuting | Base | 1 | Cork base plate stops the product from rattling in use and offers a nice shadow gap reviel to the case. | |
| Electronics | Board | 1 | Double sided copper board for the main pcb. this acts as both the wiring for the componants and the structure for the periferals. | Link |
| Slide pots | 3 | The three slide pots are the linear inputs for the device, they control pan-horizontal, pan-vertical and zoom. | Link | |
| Rotary encoders | 3 | The rotary encoders control the rotational axis and also the vew toggle short cuts | ||
| OLED | 1 | |||
| PICO 2 W | 1 |

4. 3D printed prototype
As there is takes a lot of time to make the mould for my base section I want to be absolutely sure that I get it right first try.
So I have decided to 3D print all parts first and make sure I have a full working prototype before making my final parts.
I decided to use my board from last week for my final project as it will be a big time saver over making a new board
Using the board above meant I needed to adjust my proportions a bit from the render
For the knobs, printed them in increments of 0.1mm so I could achieve a slip fit on the inputs.
For the top plate, I printed each revision only 0.2mm tall, this meant I could confirm the positions of the holes and slots without wasting material
After a few iterations the 3D printed case fit well
However after using device I noticed that the screen was being covered by my hand, so I replaced the female headers that the screen ws attached to with some male ones and used a set of female to female cables to move the screen to the top left of the device
I took this opportunity to laser cut a top plate, just to move one step closer to the CNC top plate I plan for in the final design.
In Summary
This week I wanted to take an opportunity to work on my final CAD and how all my parts are going to fit together
Things I would do differently next time
As always I would love to be further ahead, I didn’t have my final board ready for this week so I decided to make my board from last week work.
