About me Weekly Assignments Final Project

Midterm Review

During Machine Building week we made big strides with working towards the final project.

We went though some planned imprvements on the group page which I will consider in more detail and list related task.

You can read more about my final project on my final project page.

Internal components

I originally used cogs, however they were loud and not easily adjustable. I plan to use belts instead as they are standard parts and the pullys will likly be as easy to print as the cogs.

I will also be rotating the whole machine by 90 degrees so that the motor is above the drum.

Outside

I plan to mill the outside parts of the machine from wood on the cnc router. This means I will need to redesign the bearing and motor holders as the way I made them fit was using the fact the plastic will deform to my advantage.

I did not create a base or a cover for the machine. I will need to model a base which will support the walls to stand vertically and also provide a position for the electronics to connect to.

I plan to use wildcard week to create a shell using laminates to cover the internals and that will sit flush with the outside faces of the milled walls.

Electronics

I am planning to have my different hubs communicate with each other using wireless networking using esp32 c3 boards.

Networking week will hopfully give me a good understanding to build my project off of.

There needs to be inputs to control the speed, directions and a pause button for the motors.This may be on one of the nodes or a seperate piece.

Tasks

  • Redesign the drum to use belts
  • Look at buying a sutible pully for the motor that fits the motor shaft
  • Reshape the outside of the hub to be a nice curve as it nolonger needs to be square
  • Make the bearing and motor holders the exact size so that some sanding will make it a pressfit.
  • Submurge the bearing and motor holes into the wood wall for the machine.
  • Create a hole where a hensioning wheel could be placed
  • Model possible bases
  • Explore ways of joining the walls together with either joints or fastenings
  • During wildcard week expore using composites
  • Design a mould for the composite to be moulded within
  • Expore how wireless communication works during networking week and try using esp32 c3's to communicate with each other.
  • Consider the inputs I need and buy them

    • Schedule

    We have 8 weeks until presentations begin.

  • Apr 10: input devices

    • Explore what inputs I want for my project also redesign the 3D internals

  • Apr 17: molding and casting
  • Apr 24: networking and communications

    • Use the esp32 and discover how wireless communication works

  • May 01: interface and application programming

    • Possibility of using a app to control the machine as well as physical controls?

  • May 08: wildcard week

    • Use composites to cover the top of the project

  • May 15: system integration
  • May 22: applications and implications, project development
  • May 29: invention, intellectual property, and income
