18. Project Development

Assignment (week 18):

Complete your final project, tracking your progress:

  • answering:

    • What tasks have been completed, and what tasks remain?
    • What has worked? what hasn’t?
    • What questions need to be resolved?
    • What will happen when?
    • What have you learned?

Week 18 : To do checklist

  • Continue the Final Project
    • Update the schedule
    • make the box for house and Assembling it (CNC Milling)
    • make the drum for litter chamber (Laser Cutting) and Aligned the axis for assembling
    • make the PCB and soldering (Electronics Production)
    • make the box of PCB (3D Printer)
    • make the Embedded programming for electronics devices (Input & Output Devices)
    • Testing the functional system
    • Answer the questions
  • make the poster and video for Final Project
  • Documentations

Answer the questions

- What tasks have been completed, and what tasks remain?

Updates until May 6, 2022:

  • The house has been successfully made and the walls assembled

  • The drum is made of MDF board using the kerf bending method. This drum material has been successfully made, as well as the front and rear drum walls have been made. However, the drum assembly has not been carried out and the alignment for the drum rotation axis has not been carried out

  • The PCB has been made and soldered using the MCU Attiny 3216, the connector for the sensor has also been installed (need to updated)

  • Programming for the MCU has been done and tested for Input and Output devices to be used. But it has not been tested in the condition of the whole assembly system

- What has worked? what hasn’t?

  • Part of the house has been successfully assembled
  • The electronic module part has been successfully tested, but not for the whole system
  • The drum rotation mechanism is working, but the rotational speed and separation system are not running properly

- What questions need to be resolved?

  • Drum rotation mechanism, it is necessary to align the rotating axis of the drum so that the drum can rotate symmetrically and not heavy
  • Programming for the whole integrated system
  • Documentation for Final Project posters and videos

- What will happen when?

The strict schedule that I set to complete this project starting May 7, 2022:

  • May 7, 2022: improve the drum system and alignment of the rotary axis, test rotation, integration with the stepper motor, determine the rotational motion of the motor
  • May 8, 2022: Update the electronic system, install sensors and indicators, programming the whole system
  • May 9, 2022 : Assembling roof, functional testing, video shoot
  • 10 May 2022 : compile the POSTER (1920x1080, png), and Video 1080p (<10Mb)
  • 11 May 2022 : Update (if needed) Upload the poster and video
  • 12 May 2022 : prepare for presentation
  • 13 May 2022 : presentation

- What have you learned?

What I learned while completing the Final Project

  • Horizontal rotating mechanism system that requires accuracy on the axis
  • Power transfer mechanisms and determine motor specifications for the power required in a system
  • Logic programming on smart (automatic) and complex systems
  • Comprehensive system testing

What I learned during Fab Academy

During the 6 months of participating in FabAcademy activities, I learned many lessons, including:.

Technical aspects:

  • I am a mechanical engineer, however there are many new perspectives that I found in the field of mechanical engineering, such as cnc for wood, art design, etc.
  • new knowledge and skills that I got in the field of electronics and instrumentation, with the latest technology updates used around the world, such as sensors, MCU, embedded programming, accessing communications etc.

Other aspects:

  • Documentation, is a new thing for me to be able to document something that I learn and do. It was quite difficult at first, but after a few weeks I got used to it and it turned out to be very helpful in the sessions that followed, so I really wanted to document a lot of things, but due to time constraints
  • Time management, one thing that I am concerned about right now is time management, how to be on time in doing things. This will be very helpful in our future sustainability when building and running Fablab in Indonesia
  • Communication, at first I felt inferior and wasn’t sure I could communicate well with all participants and instructors, but with frequent interactions I got used to it and it was easier to communicate
  • Global network, I can meet great people around the world who are experienced in creating open innovations, can imitate and develop potential collaborations

  • Tired, working day and night with limited time and resource targets, but finally relieved and happy to be joining the Open Innovation global ecosystem and community....

  • Thank you all: Neil, Global Instructors, Local Instructors, Fablab Kamakura, all students 2022…
