Project Ideation
1- Tell us about the purpose of your project. Which problem does it solve? Why do you care about this? What were you inspired by? Include images and videos of similar projects
Centrifuge
A centrifuge is a device that uses centrifugal force to separate various components of a fluid
I was influenced by the DIY bio team at London University, who created lab equipment using 3D printing, laser cutting, Arduino, and electronics to lower research costs.
2- Describe the project idea and general features. How would it work?
Final Project Proposal
the idea of the centrifuge is a device that uses a rotor to separate particles from a solution.A centrifuge's rotor applies a centrifugal force to each particle in the sample, which causes the particle to sediment at a rate proportional to the centrifugal force supplied to it.
sensors are provided to detect each of the buckets if the sample is missed the gadget will not function until it detects a sample in the bucket.
Buttons will be used to control the centrifuge.
t uses a 12V DC motor and a simple rocker switch. It also has provisions for adding in a microswitch and enough room for adding in a micocontroller (like an Arduino Nano) to add timing and cycle functions.
This DIYbio micocentrifuge. A video overview can be found here: https://youtu.be/Od_wNhkoEakIt uses a 12V DC motor and a simple rocker switch. It also
3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop
Project Planning
4- Describe the Technical Modules that your project consists of
Construction Parts
Fusion 360 software will be used to design the body pieces, which will then 3D printed.
Input (Sensing and/or User)
the device will take in put from the porentiometer to start rotation and to change the speed also there is a slide switch when it is off the device will take input from the temperature sensor to rotate.
Action
Dc motor for the rotation till the separation of the samples and buzzer as an alert when the temperature change to the range can lead to degradation
Brain
To take inputs and generate actions, an Arduino UNO board will be used.
Power Management
DC power supply
5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
Minimum User Features
Example:action : rotate and separate the sample
Input :adjust the speed
Complete User Features
Action :LCD showing the speed and time
Input: adjust the time
sensing: Temperature
Nice-to-have User Features
Action :Red led showing the empty rack to adjust the balance
another rack for tubes with different size
alert when the temperature unsuitable for the samples
