Assignment:
Propose a final project masterpiece that integrates the range of units covered, answering:
Introduction
This week, our assignment was to think deeply about our final project and how we wanted it to turn out. In order to do this, we were given some questions to think about, such as what does the project does, what materials it will use, how much it will cost, etc.
What will it do?
As seen on my final project page or my week 1 page, I want to create a smart adjustable desk that can be adjusted vertically using a mobile app.
The purpose of this project is that many people are face the problem of hips and back. If you stand or move around during the day, you have a lower risk of early death than if you sit at a desk. If you live a sedentary lifestyle,
you have a higher chance of being overweight, developing type 2 diabetes or heart disease, and experiencing depression and anxiety.
The advantage of this desk is that we can work while sitting on the floor, sitting on a chair, or standing position.
Who's done what beforehand?
I have checked around the Fab Academy search engine, but nobody has developed such a thing similar to this. When I am scrolling Youtube to create new ideas while watching videos suddenly I got an idea through a weight lifter machine that works manually that is the same mechanical aspect as my project, But my application is different. I want to make an electronic desk I use a DC gear motor to connect with a microcontroller So I can easily control it through a mobile app.
What will you design?
PCB Controller board
The system main body
The 3D printed components such as electronic parts enclosure
PCB input and Output device Boards
What materials and components will be required?
ATMega328p along with circuitry
Bluetooth module
Motor Driver 12VDC, 28Amp
Dc gear Motor 12VDC, 5Amp
Bearing 1/64
Lead Screw with nut
Linear Bearing 8mm
Motor pulley
Scissor Bushes
Adaptor 12VDC 2.5Amp
PLA 3D Printed Parts (100g)
Chipboard Sheet 8*4ft, 16mm
Nut bolds 3.5-inch 12mm
Steel rod(MS) 8ft rod
L-Shape Angle 3ft
Angle Clip
Where will they come from?
most of the components and material are from FABLAB Khairpur, these are some components which I bought, the list is mentioned below:
Motor Driver components(Local Shop - Gulshan-e-Iqbal Karachi )
Bearing 1/64 (Bohra Pir Orangzaib Market - Karachi)
Lead Screw with nut (Electronic Shop - Karachi)
Linear Bearing (Electronic Shop - Karachi)
Motor pulley (Electronic Shop - Karachi)
Scissor Bushes (Lathe Work Shop - Khairpur)
Nut bolds 3.5-inch 12mm (Khalid Brother Shop - Khairpur)
Steel rod(MS) 8ft rod (Local Shop - Sukkur)
L-Shape Angle 3ft (Lathe Work Shop - Khairpur)
Angle Clip (Lathe Work Shop - Khairpur)
How much will it cost?
I have tried answering all these questions using the table bellow
What parts and systems will be made?
PCB of Atmega 328P board
PCB of Motor driver board
Press-fit wooden desk
Vinyl cutting
Android Application
3D printed Circuit Box
Networking between 328P and Bluetooth HC-05
What processes will be used?
Input Devices (measuring the height using ultrasonic sensor )
Output Devices (Motor controller)
Wireless Communication (BLE) between smart desk and Smartphone or PC
Vinyl cutting for decoration
3D circuit box
Smartphone/PC applications to control the smart desk and measure height using an ultrasonic sensor
What questions need to be answered ?
When a person is at a table, how can it be adjusted to accommodate different users ?
How to improve the load capacity of a weight that is greater than 5kg ?
How to make application more user friendly so they increase no. of features as well ?
How to market this product ?
How may the movement of the body be improved ?
How will it be evaluated?
After the project is completed, we may adjust the smart desk using an android application and manual button and also measure the height of desk using ultrasonic sensor and LCD display.
