Weekly Assignments Final Project About me

WEEK 18

Applications and Implications, Project Development

How the week started

This is ongoing along with the final project execution. Still also a time to realsie and analyse how much my project has evolved or cut short.

How the week ended

This week's documentation was doen in a day. A pretty long exhausting day I would say.

Week 18’s Assignment

Applications and Implications:

    Plan 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
    • 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.

    See Final Project Requirements for a complete list of requirements you must fulfil.

Project Development :

    Prepare drafts of your final project summary slide (presentation.png, 1920x1080) and video clip (presentation.mp4, 1080p HTML5, < ~minute, < ~25 MB), put them in your root directory, and check that they are linked in the final presentation schedule

Assignment

What will it do?

In simple words it is a kinetic clock. A kinetic clock that denotes the time of person of your choice, who is living in another country. It leans more towards the artistic appeal of a decor, serving as a subtle time telling device on your wall.

Who's done what beforehand?

Well I am inspired from an already exisitng product. The light in that has to be manually moved


video source

I have seen similar videos of this on Pinterest. They move the sun manually, my first thought was to automate this. Then I was wondering why to see sun move when I already know the time of my place. That is when I thought of the dual clock I use to check my friend's time who is in Dubai. Thus born this idea of moving the sun based on the location of another person. Now I can have a device which passively tells me time at my friend's location

What will you design?

I am designing a kinetic clock + wall decor. The product has an intergration of Mechanical, Electrcial and Software Systems.
Mechanical system

Source

I am using a curved gantry to move the sun in the path of an arc. The gears will be designed on Fusion. The 28byj-48 stepper motor is mounted on the pinion. The curved grantry would either be 3D printed or lazer cut on acrylic sheet.

Image source - Youtube - Accurate Peripheral Motion | PRT2 Curved Rails | Animation

Created on procreate

The frame is to be made using rubwood, cut on Shopbot or Zund machine. The images are created by stacking synthetic paper. The paper will be lazer cut to create the lightbox frame.

The pinion will be 3d Printed

Electrical system

Milling of pcb on Modela, soldering and testing the baord. The following components are used Microcontroller -xiao esp32c6 connected to rtc, stepper motor, photo-transsitor, neo pixel ring, limit switch, capacitative touch.

Software system

Use of Ardunio to program xiao.

What sources will you use?

The pretty basic source to do anything would be to Google Search. Pinterest - without which my project would'nt exist. I do need the help from instructors of Super Fab Lab Kochi.

mechanical - gear design - Gear Generator
pcb design - Input week & Output week
Neo-pixel ring PCB - Custom NeoPixel Rings From Scratch!-By- Hyper Ion Namitha Aravind
Programming and system integration - ChatGPT, Claude ,Gemini

I would also be discussing doubts with the AI mentioned above.

Material - Source & Cost

What processes will be used?

What questions need to be answered?

I have to figure out the gear ratio. I have to design and try one a curved gantry. I have to make sure the pinion does not side off or have trouble climbing back up the arc. If the gear will be able to hold the motor and move, I am told it will.
The thickness of the frame can be fixed after assembling the gantry and mounting the neo pixel ring. I have to figure out the height at which the diffusion is good. I also have to figure out the packing process

How will it be evaluated?

It will depend on how the microcontroller is able to calcuate the steps and move the sun (neopixel ring). The sun has to move based on the time from timezone set in the app.

Project Development

I have added a trial slide to the public folder to understand how to upload the image and its constraints

SLIDE - Presenation.png how to edit and add

I have created the slide using Affinity and pasted the image I drew in Procreate which is an ios app

The slide has to have few details like a title, image, description, creative license, fab logo, fab lab kerala logo and name

1 / 6 On opening Affinity click the plus symbol on the window to create a new document. The image size is 1920 x 1080 pixels
2 / 6 Affinity is so simialr to photoshop. I wanted to create a simple template for the slide. I used the shape tool or press U and drew the rectangles. Press T for placing text.
3 / 6 I added a guide . VIEW > MARGINES AND GUIDES. It opens into a dialog box, the changes in values, the changes in the guiides are seen on the workspace.
4 / 6 The template I went for.
5 / 6 To export the file. FILE > EXPORT or shortkey [Alt+Ctrl+Shift+w] Selct the PNG format from the left side panel. Make sure the size is still 1920x1080px . Click export and choose the file location to save.
6 / 6 IMPORTANT : save the file name exactly as presentation small letters and png format. SAVE in PUBLIC folder In the image I am replacing the file I made earlier

VIDEO - Presenation.mp4 how to edit and add

I tried to edit in Kdenlive. In Handbrake I tried to compress the video with presets shared in lab

Kdenlive ediitng

1 / 6 Open Kdenlive>New Project. Drag and drop the files in the top left window. then drop the files to the below track to edit. click to transcode if asked
2 / 6 the selected video is previwed in the window. I have muted the Audio of that video. I added an image to the beginning of the video, drag and dropped.
3 / 6 To edit the video speed. Right click on the video and click change speed.
4 / 6 Another dialogue box with the speed slider appears. Adjust the speed or enter the value. Click okay
5 / 6 To complete the editing, Select FILE > RENDER
6 / 6 In RENDER PROJECT , Choose the location to save the file. Then choose the video format MP4-H264/AAC, then render to file. File name is important presentation.

Handbrake- video compresser

1 / 3 A preset was shared with us. I will add it below. Open handbrake on the toolbar select PRESETS > ADD PRESETS.
2 / 3 Drag and drop teh file into handbrake. now I selected the preset I had added before.
3 / 3 In the below toolbar, select dimensions. Make sure the resolution is 1080p HD ,Scaled Size : 1920x1080px Choose the location to save the file. Then CLICK Start Encode.
