18. Project development

This week I worked on defining my final project idea and started to getting used to the documentation process.

Assignment

Complete your final project, tracking your progress:

What tasks have been completed?

  • Completion of the basic concept and programming for the final project was done, in the form of my Input Devices assignment
  • Materials have been obtained to build the Base for the vacuum attachment
  • A repaired, carded for disposal Shop Vac, with cover housing, was obtained to create the suction needed
  • The 3D design for the PCB has been completed
  • Initial Testing of the FSR sensor as well as the ShopVac
  • 2D design MDF Board piece for the chair to attach to the base piece

What tasks remain?

  • To assemble the major pieces for the base
  • 3D Printing of the PCB enclosure still has to be completed
  • Attachment of the hose system for the suction aspect still has to be developed
  • A costing of all materials that were not recycled has to be determined

What’s working?

  • The ShopVac is able to perform the suction needed
  • The program to detect the change in pressure via the FSR is working as intended

What’s not working?

  • The base, with the shopvac mounted, seems to change the stability of the it entirely
  • The FSR sesnor, when added to the assembly, didn’t work as intended.

What questions need to be resolved?

  • How to get the FSR sensor to work as intended

What will happen when?

  • The vacuum chamber, that holds the debris becomes full. Maybe an additional mechanism is needed to engage and trigger the FSR sensor
  • The chair is in use, and clients are present, would the noise from the vaccum be unbearable

What have you learned?

  • Always work on major projects, in stages.
  • Leave a lot of room for improvement, in any and every aspect of this project
  • Ensure to measure twice, and cut once (most technicians would know ehat I mean)
  • Proper time managment is essential for every part of the development of major projects
