17. Applications and Implications¶
This week I worked on define the scope of my project, and develop a project plan including a bill of materials(BOM).
Overview¶
Propose a final project masterpiece that integrates the range of units covered, answering:
- What will it do?
- Who’s done what beforehand?
- What will you design?
- What materials and components will be used?
- Where will come from?
- How much will they cost?
- What parts and systems will be made?
- What processes will be used?
- What questions need to be answered?
- How will it be evaluated?
What will it do?¶
This is a smart night lamp that allows users to remotely control the light switch, adjust the color, and monitor the room’s temperature and humidity in real-time. Its gentle color temperature aids sleep and provides illumination for nighttime trips to the bathroom. The light features a square design with wooden stripes forming the character “中” (meaning “center” or “middle” in Chinese), evoking a sense of classical elegance. This design element is reminiscent of the profound heritage of Chinese culture and traditional patterns.
Who has done what beforehand ?¶
I gain remotely control switching of lamp from this video. The blogger in the video uses MQTT to achieve remote on/off control of an LED light strip.
I gain inspiration from this outlook of the lamp. I was really impressived by the patterns and also the clever thread structure design, and press-fit design too! Its pattern reminds me of the ancient Chinese pattern, and this idea encourages me to design a Chinese traditional pattern, Especially some patterns of cultural relics in the Forbidden City. I hope I can design these patterns and apply them to my project works.
What will you design ?¶
- Traditional/ Ancient Pattern
- Lampshade outside frame with the pattern X5
- Integrated lamp shade (bottom removed)
- Lamp shade bottom and corner screw holes x1 ; corresponding supports with thread structure x4
- Lamp shade trepanning with thread structure, with a support connected to it
- LED light strip wiring method
- The power method / The power bank position
- The position of the PCB, temperature sensor
- User Interface
What materials and components will be used ?¶
- Plywood
- PLA filament
- LED strip
- Grove DHT11
- XIAO ESP32 C3
- 502 glue
- CCL(copper-clad plate)
- Dupont thread
- Tin bar
- Sand paper
Where will they come from?¶
Chaihuo Maker Space, Shenzhen
- Grove DHT11
- XIAO ESP32 C3
- CCL(copper-clad plate)
- Dupont thread
- Tin bar
- Sand paper
- Other componets on the PCB, see as bellow
ISA Science City Fab Lab
-
Plywood and PLA filament
- LED strip
How much will they cost ?¶
The cost may cover these components below, for polywood and PLA, it may just about 20 RMB.
| Component | Amount | Price | Notice |
|---|---|---|---|
| LED strip | 1 | 34.9 ￥ | |
| XIAO ESP32C3 | 1 | 4.99 $ | |
| Grove DHT11 | 1 | 5 $ | |
| CONN HEADER SMD 10POS 1.27MM | 1 | 0.88$ | |
| CONN HEADER SMD R/A 4POS 2.54MM | 1 | 0.93 $ | It’s a 6POS component, you need to adjust it to 4POS manually |
| CONN HEADER SMD R/A 3POS 2.54MM | 1 | 0.93 $ | It’s a 6POS component, you need to adjust it to 3POS manually |
| Tactile Switch SPST-NO Top Actuated Surface Mount | 1 | 1.08 $ | |
| LED BLUE CLEAR 1206 SMD | 1 | 0.23 $ | |
| RES 1K OHM 1% 1/4W 1206 | 1 | 0.1$ | |
| RES 499K OHM 1% 1/4W 1206 | 1 | 0.10$ | |
| JUMPER WIRE F/F 6” 20PCS | 1 | 2.10$ | |
| Dupont Cable | 1 | 8.99 $ | |
In total , materials and components may cost around 23$.
What parts and systems will be made ?¶
- The inner part structure to support PCB,LED strip, Power wire
- The middle lampshade
- The outlook lampshade
- Micorcontrolers and electronics system on PCB
- MQTT Communication & User interface
- Led Color Mode
What processes will be used ?¶
I will work on my PCB schemetic diagram first, this enable the following steps for the whole project. Then I will mill the PCB and also make a copy one in case the initial one not working. After that, I will work on the outlook of my project. I need to define the traditional patter, and laser cut it. Last, I will work on the user interface, networking and communication, edit the program to enable the night lamp.
What questions need to be answered?¶
- How do the communication implement?
- How to design the user interface?
- How to assemble different parts in a better way?
How will it be evaluated ?¶
Project should incorporate:
- 2D and 3D design
- Additive and subtractive fabrication processes
- Electronics design and production
- Embedded microcontroller interfacing and programming
- System integration and packaging.
Is all functions working?
- remotely turn on/off
- remotely color adjustment
- real-time data visualization
Extra credit:
-
User Interface simple and beautiful
-
Programming:
No time delay / laggie networking when operating.
