Final project

My Final Project Proposal 1

I am proposing my idea to design and fabricate an Automatic Whiteboard Cleaner .Whiteboards are commonly used in educational and corporate settings, but manually cleaning them are time consuming and inconsistent. Therefore, this clearner will help the tutors and students to save time and hence provide more consistent results. This would target to benefit schools/universities, offices or any spaces that frequently use whiteboards. My rough sketch below:

sketch idea

Components required with functions:

1. 3D printed gear(rack and pinion type) to connect with arm and control movement of cleaner across the board.
2. Make Microcontroller Board to control the motors.
3. Motor controller (driver modules L298N) to control stepper motors
4. Stepper motor to drive the gears that move the cleaning mechanism.
5. IR/ultrasonic type sensors to detect edges of board, to follow specific path.
6. cleaning cloth/pad
7. Control interface switch to start or stop.
8. USB power supply
9. Small size whiteboard

Final Project Proposal 2

Final project idea- 2

My second idea is to design and fabricate Automatic Hand Sanitizer Dispenser. In the World, after COVID-19, the use of hand sanitizers has become the key factor on health system. This idea would continue to benefit the community. As shown in my figure, i will use plywood for casings, while dispennser and its straw will be made using 3D printer. I will try to make PCB board as my controller for motor and other devices.

Final Project

I have decided to choose Automatic Hand Sanitizer Dispenser as my final project.

During my third week of Fab Academy, my local instructors called upon me to present my final idea and discussed for the requirements of the materials required.

project idea discussion

I have got some recommendatons to look for container feature, to include both laser cut and 3D printing, top lid should be able to open/close to replace solution.I was also advised to plan to place the electronic devices on board, and to add vinyl stickers to look good.

First Prototype using Cardboard for Final Project.

During, fifth week, i have prototyped the casing for my final project.

I am slightly changing my project name as Automatic hand washing system as recommened by my instructors.

Here is my work using cardboard.I have created two case boxes, one for detecting while entering to washroom with ultrasonic sensor, sound and ESP32 microcontroller.

detect system

Another case box created was for soup dispenser along with motor and pump, ultrasonic sensor which can be displayed near wash basin.

Further, i was instructed to study on the force required to pour/dispense the soap solution and its mechanism to develop.Also to look on motor and its position, load for dispenser container.
