17. Applications and implications¶
Propose a final project masterpiece that integrates the range of units covered, answering:¶
- What will it do?
- Provide entertainment to young’uns, and adults, during long drives!
- Who’s done what beforehand?
- Some years ago a company called Apple released products what they called “iPod” and “iPhone”. But the price paid for them was too high, both in terms of dollars and on-the-road fortitude of families. But I rely mostly on designs that have been provided in class. I have no consious knowledge of similar devices.
- What will you design?
- I’ll design two interconnected modules, capable of providing some level of entertainment to the users. One is intended to be mounted in the front passenger compartment of a car, and the other is intended to be mounted in the rear seat of the car.
- I’ll make the electronic components needed, the vehicle mounts, the casings and program the modules.
-
What materials and components will be used?
-
The project will be comprised of a number of materials and components, such as PLA plastic, PCBs, MDF, acrylic and various electronic components.
-
BOM(Bill of materials) for my setup, which is 1x control board, 2x button boards, 2x power boards, 2x jack boards
-
| Component | Qty | Explanation |
|---|---|---|
| SMD LED | 6 | For the button boards |
| 1k res | 6 | For circuits |
| 4.99k res | 6 | For circuits |
| 1uf cap | 5 | To regulate current fluctuation on boards |
| BUTTON_B3SN | 6 | 3x buttons per button board |
| ATtiny 1614 | 3 | Processors used on control board and each button board |
| 1x2 pin header | 2 | Various connections |
| 1x3 pin header | 7 | Various connections |
| 1x4 pin header | 1 | Various connections |
| 1x6 pin header | 3 | Various connections |
| 1x7 pin header | 1 | Various connections |
| USB_B_Mini | 2 | USB connectors |
| Regulator_Linear_NCP1117-5.0V-1A | 2 | To provide power to each unit |
| SJ1-2533-SMT | 2 | Jack connectors, for data wire |
| Double wires | 1 m | For creating data wire between parent and child unit |
| USB cables | 2 | For powering devices |
| Jumper wires | 20 cm | For connecting boards |
| Plywood | Scraps | For the back boards |
| Plexiglass | 1 sheet or scraps | For the cover of units |
| Nuts and bolts | 8x | Attaching back plate to middle and front cover |
| Small screws | 7x | To attach boards to backplate |
| PCB | 1-2 plates | For milling of boards |
| 3D Print filament | I used what I had laying around |
- Where will they come from?
- Most, if not all of the parts, will be sourced in the FabLab.
- How much will they cost?
- As I predicted, the cost is very low. For us here in the lab in Iceland, the cutting of a fresh Plexiglass plate is probably the most expensive thing. The ATtiny 1614 are below $1 at Digikey, and most other items very cheap in bulk and all are part of our FabLab inventory. I will set price at the sub $50 range!
- In terms of machine time, this project requires only a short a mount of time in the laser cutter, a bit of (large) milling time (~1h with setup), some small mill (PCB) time (~5 hours, if all goes well?), 3D printer time (~20 hours guesstimate) and some quality time at the soldering station!
- What parts and systems will be made?
- Electronic circuitry will be made, both enclosures and mounts.
- What processes will be used?
- Lasercutter: For parts of the casings
- 3D printing: Also for the casings and mounts
- Electronic production: For the electronic components
- What questions need to be answered?
- What do I need to do make things ‘childproof’? Both in terms of risk and safety, and in terms of durability.
- How will it be evaluated?
- Does it work at all?
- Have you been in the situation that a child in the backseat is bored and restless?
- What lengths are you willing to go to entertain said child? Learning to produce electronic components, programming and basically almost anything else??
- A big part of the project is to spark interest in making stuff, how things work and DIY mentality. If the final outcome might look like it could, I’d consider it a great success.
Your project should incorporate:¶
- 2D and 3D design,
- additive and subtractive fabrication processes,
- electronics design and production,
- embedded micro-controller interfacing and programming,
- system integration and packaging
- Where possible, you should make rather than buy the parts of your project.
- Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable .
