16. Applications and implications¶
This week I worked on defining my final project idea and started to getting used to the documentation process.
Assignment¶
Your project should incorporate
- 2D and 3D design,
- additive and subtractive fabrication processes,
- electronics design and production,
- embedded microcontroller interfacing and programming,
- system integration and packaging
Where possible, you should make rather than buy the parts of your project Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable
Propose a final project masterpiece that integrates the range of units covered, answering:
What will it do?¶
The purpose of the this final project is to ease the burden placed on Barber’s/Hair Stylists by decreasing the volume of hair (waste product), that they would have to remove upon completion of their subtractive work. The device can be operated/ controlled via a switch or timer system, which would allow the barber to, always have control of its primary function.”
Who’s done what beforehand?¶
Throughout my research, no one has created or built this concept. There are variations of salon vacuums in exitence, for example this one from Comfortel, but not integrated within the actual salon chair such as mine.
What will you design?¶
I will design the following components:
- A PCB (to integrate with the sensor I propose to use)
- Various 3D Printed parts (Used in different aspects of the build)
- A redesign of the chair system and base of the salon chair
What materials and components will be used?¶
I will essentially be recycling the majority of materials for this project. Most of which was sourced locally, and the electronics sourced online via various websites. (see table below)
How much would they cost?¶

Where will they come from?¶
Most of the materials would come from in house, that is, at the Insititue I work for. As we’re in the process of relocation, there has been alot of disposal activity taking place, fulfilling the term, “One man’s garbage, is another man’s Treasure!”. The remainder of materials would be sourced online (for electronics), and locally at hardwares.
What parts and systems will be made?¶
- The Vacuum stand (chair base)
- The PCB (electronics)
- 3D Printed enclosures/ parts
- Plexiglass Cover for PCB Enclosure
- Support base for repurposed office chair (MDF)
What processes will be used?¶
There will be a number of processes being used for this project. Some are, 3D printing for the various parts and enclosures, CNC Routing for the chair base attachment, Precision Milling for production of the PCB, Soldering for the production of the PCB, and a good bit of adjusting and fitting when assembling the ShopVac/ PVC attachments.
What questions need to be answered?¶
- Will the FSR sensor work as intended?
- Will the suction power be enough for operation?
How will it be evaluated?¶
As its main function is intended, which is, to vacuum debris/ hair/ etc.
