Week 18 : Applications and implications

• Propose a final project that integrates the range of units covered.
  Think of your project plan as an 'installation and implementation guide' for the future. How will others be able to make your project by reading your documentation?

Final project

My final project will be a trash bin with several bins to sort wastes. It will weigh wastes to compute ecological impact of your way of life. And it will also be modular to go with what type of wastes you want to recycle.

The project can be split in 6 parts:

Main bin
Each bin will be mabe with two containers. The inside one will slide in the outside container.

Bin link
Bins should be removable for the system to be modular, suitable for each situation.

Bin lid
First version, a manual lid you can open by hand. A second version wich can be open by foot can be made later. This part is optional

Weigh device
The most important part of the bin. A mechanical system will transform weight to a potentiometer rotation .

Electronic devices
A small board to each bin connected to a main one or just one connected to bins.

Board application
The app will ba a firmware wich compute bin weights

for each part, we can define 4 states of progress:

from the idea to 3D design, board schematic

3D print, laser cut, engrave the device

assemble, verify, debug and return to prototype state if necessary

write documentation for user to know how to make, use

Questions to be answered

• what will it do?
My project is a bin helping you to sort your wastes and measure your ecological impact
• who has done what beforehand?
It's easy to find bins where you can sort your wastes but I didn't find one able to weigh them and show you how much you product
• what materials and components will be required?
• 3mm MDF to build bins and lid
• PLA for link pieces and weigh system
• ATTiny 84, I2C LCD Display, potentiometers and FR1 to make the board
• where will they come from?
Most of them will come from my Lab. If available, some will be waste material
• how much will it cost?
I'd like the project to cost less than 30€
• what parts and systems will be made?
All will be made but not electronics components
• what processes will be used?
• 2D design and laser cutting for bins
• 3D modelling and printing for links and weigh system
• Electronic design and production
• what tasks need to be completed?
All parts : bin, link, weigh system, electronic and application need to be completed
bin lid is optional

• what is the schedule?
See below
• how will it be evaluated?
Bin has to be able to measure weight and compute when you add something
