Individual Assignments

  • Prepare drafts of your final project summary slide
    (presentation.png, 1920x1080) and video clip
    (presentation.mp4, 1080p HTML5, < ~minute, < ~25 MB),
    put them in your root directory, and check that they are linked in the final presentation schedule
  • Plan a final project masterpiece that integrates the range of units covered, answering ↓↓↓
Applications and Implications Answer
What will it do? You can practice to improve your control to become better at table tennis.
Who's done what beforehand? We could not find the same idea in particular.
What sources will you use? From the reference link sites posted each week
What will you design? - Case of the main unit
- Case of the sensor side
- Sticker of the point to be placed on the stand
- The board
- What materials and components will be used?
- Where will come from?
See BOM below.
How much will they cost? ¥7,164(JPY)
What parts and systems will be made? The sender and receiver cases were made with a laser cutter and a 3D printer. The board was designed and milled by me, and powered by LiPo 3.7V from the battery input terminal on the back of the XIAO ESP32S3.
What processes will be used? See develop page.
2D design (Illustrator) : Score stickers
3D design (fusion360) : Part of the case and Sender side
Laser cutting (XTool P2S/Illustrator) : case ans score sticker
CNC milling : Board
3D printing :Case for input device and output device
Electronics design (Kicad) : design a XIAO ESP32S3 board
output devices : DFplayer or OLED display
input devices : Piezoelectric Device
networking and communications (ESP-NOW/Arduino IDE): Networking with XIAO ESP32S3 board
What questions need to be answered? Do you understand how sender-receiver communication takes place?
How will it be evaluated? The transmitter side (piezo sensor) detects the pin ball hit, and the receiver side works with it to check if DFplayer and OLED Display function properly.
- Your project should incorporate 2D and 3D design,
- additive and subtractive fabrication processes,
- electronics design and production,
- embedded microcontroller design,
- interfacing, and programming,system integration and packaging
See develop page.
2D design : Case, Score stickers
3D design : Part of the case and counter for input device
Laser cutting : Case,Score stickers
CNC milling : Board
3D printing : Case for input device and output device
Electronics design : design a XIAO ESP32S3 board
output devices : DFplayer or OLED display
input devices : Piezoelectric Device
networking and communications : ESP-NOW using XIAO ESP32S3 board
Where possible, you should make rather than buy the parts of your project under manufacture
Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable -
- what tasks have been completed? 1 Production of sensor side base
2 Produce the main board
3 Make a case for the sensor side
4 Build a case for the main board, speakers, and display.
5 Make a sticker OR mark of the score to be placed on the table.
6 Thinking about how to attach the sensor to the back of the ping-pong table.
7 Production of parts for mounting sensors on the back of a ping-pong table
8 Write programs on the main board and the board on the sensor side, and have them communicate wirelessly via ESPNOW.
9 wiring and assemble
10 Slide production
- what tasks remain? 1 Video production of the final project
2 Final Presentation
- what has worked? what hasn't? All mounted devices are working. (OLED Display,DFplayer Mini,Speaker,Piezo sensor)
- what questions need to be resolved? - Because the material of the target placed on the platform was paper, the target was easily blown away by the fast ball wind.
- Currently, Sender side case is fixed with adhesive tape, but if there is a better way, we would like to change it.
- what will happen when? There will be a Final Presentation on 6/9.
what have you learned? When I calculated the price of each individual component, I learned that they cost more than I had imagined and how wonderful the world's cheap, high-performance products are.
