17. Applications and Implications¶
Propose a final project masterpiece that integrates the range of units covered. Your project should incorporate:
- 2D and 3D design
- Additive and subtractive fabrication processes
- Electronics design and production
- 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.
QUESTIONS¶
What will it do?¶
My project is a modular construction that uses sensors and motors to be able to be automated, it can have a single section or be extended. I proposed a small version to be able to build it and there were many challenges, from the limitations of the dimensions of the 3d printer, to the precise joining of the materials.
Who’s done what beforehand?¶
Stand designs have been done before but they are not mobile or adaptable to the space and take a long time to set up and move.
What will you design?¶
It is a commercial stand module that can be adapted to any space, you can have an exhibitor or extend it and have much more space. My point is to demonstrate on a small scale that it is possible and later to be able to apply it not only to furniture, but also to architecture.
What materials and components will be used?¶
For structure:
MDF 3mm
3d printing
Acrylic 3mm
For decoration:
Vinyl
For electronics:
Copper plates
Attiny 44 and Attiny 45 Microcontrollers
End stop limit switch
Stepper motor
Power supply
Additional elements such as resistors, capacitors, FTDI, ISP, resonator, wires, etc.
Where will come from?¶
The materials are provided by the Fab Lab Esan node where I am located, I only had to buy the end-of-travel sensor from a local supplier.
How much will they cost?¶
What parts and systems will be made?¶
Estructure and electronics.
What processes will be used?¶
3d printing, laser cutting, plate design and programming.
What questions need to be answered?¶
3D design with measurements and correct tolerance for assembly of parts, varies according to the material and position in which it will be placed. Mechanism operation with motors, rack and pinion. Plate design and programming.
How will it be evaluated?¶
The motor and rack mechanism must work correctly, the assembly of the parts must fit together, the sensor must stop the rack travel.
