Applications and Implications

Assignment:

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? - How much will they cost? - What parts and systems will be made? - What processes will be used?

Your 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 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

Learning outcomes

  • Define the scope of a project
  • Develop a project plan including a bill of materials (BOM)

What will it do?

  • The Impromtu Speech Selector will take in inputs from the webserver hosted using Xiao esp32c3 which will be stored in google sheets. Upon pressing the emoji button(the randomiser button), a random topic will be displayed on the i2c lcd and a random grade and a roll number will be displayed (from the code which will be programmed through arduino ide). After a student is picked and done with the speech, the teachers will either approve or disapprove the speech. If approved, the thumbs up button will be pressed and the roll number will be removed from the loop. However if disapproved, the thumbs down button will be pressed and the roll number will be inserted back in the loop (meaning nothing will change).

Who’s done what beforehand?

What will you design?

  • I will be designing my enclosure using fusion 360 which will contain a top and base which will be laser printed, the middle layer which will be milled using the shopbot and the button covers which will be 3d printed. I will also be desigining my PCB board and fabricating it with using Roland SRM-20 which will cover the electronics part.

What materials and components will be used?

I will be using:

  • 20x4 i2c lcd
  • xiao esp 32c3
  • Tactile push button - 3x
  • Piezo buzzer

Where will they come from?

  • So most of the components are present in the lab itself so I did not have to order any components and the PLA filament is from Prusament.

How much will they cost?

  • Here is the list of the component’s cost:

What parts and systems will be made?

  • Top, middle and bottom layers
  • Button covers
  • Electronics

What processes will be used?

  • For designing, I am using fusion 360 and for cutting and milling the enclosure, I will be using the 3d printer, laser cutter, vinyl cutter and CNC. For my pcb boards, I am using KiCad for designing and MODS to create the rml file. For milling my pcb board, I will be using the Roland SRM-20.

What questions needs to be answered?

  • “Will my system integration turn out well or not?” as I am still working on it. So this is the BIGGEST question that needs to be resolved for me.

How will it be evaluated?

  • My project should be successful if it can incorporate 2D and 3D design, additive and subtractive fabrication processes, electronics design and production, embedded microcontroller interfacing and programming, system integration and packaging. The project should be able to easily edit and store Student ID, Student Grade and Topics and should be used by anyone to make the Impromptu Speech Selection process more efficient (and fun!). In this project, the input will be a tactile push button and teh output will be the displaying of topic, grade and roll number.

Workplan

Here is my workplan for the last few days:

Since I have been engaged with some other activities in school, I have not been able to work for my final project so far. SO after I was done with my work at school, I made the workplan I shared above. As we only had only less than 2 weeks, we decided to work on our final projects instead of attending the usual classes. Due to this I was able to fully work on my project according to my plan.

The design files are in my final prject poge!

THAT’S IT FOR THIS WEEK!!!

HAVE A NICE DAY!!
