Week16- Application and implication

Introduction

Finally, we come to the end. Well, not really the end but almost the end.

Assignment

  1. Propose a final project masterpiece that integrates the range of units covered, answering:

    1. What will it do?
    2. Who's done what beforehand?
    3. What will you design?
    4. What materials and components will be used?
    5. Where will come from?
    6. How much will they cost?
    7. What parts and systems will be made?
    8. What processes will be used?
    9. What questions need to be answered?
    10. How will it be evaluated?

  2. Your project should incorporate 2D and 3D design,

    1. additive and subtractive fabrication processes,
    2. electronics design and production,
    3. embedded microcontroller interfacing and programming,
    4. system integration and packaging

  3. Where possible, you should make rather than buy the parts of your project

  4. Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable

Q&A

1. What will it do?

My final project is named Bright Bright lamp. The name is literally what the lamp function as . Firstly t is very bright as it can sense light intensity and motion and turn on and off the LED and secondly because the lamp is bright as it uses LED bulb. The bright bright lamp uses an ESP32 Wroom 32 as an microcontroller. The input used are LDR sensor and a doppler sensor. The output is a solid-state relay which acts as an switch to turn the LED on and off.

2. Who's done what beforehand?

Motion sensor lamps are available in the markets which those are manufactured by the neighbouring countries. We don't have any motion sensor lamps that are manufactured in my country so far.

This is an example of the motion sensor lamps is displayed when I click on an indian shopping site image

Since the fabacademy is an open source, I took the advantage of it and looked at the amazing works done by the previous graduates of fabacademy to get a kick-start at how should i proceed.
