Computer-Controlled Cutting:
1. Laser Cutting

1. Used parametrics of Flatfab to arrange for my drawing paths

2. Experimented with multiple tesselation designs found online and tweaked their designs to see their effects on the print. Checked for their tensility, bendibility, flexibility and rigidity in relation to other designs

3. Designed pressfit locks that can rotate about min. one axis.

4. Printed a 4.5 m MDF made out of press fitting .75 m strips together which i'll use to tie my turban.

5. Calculated the kerf of the laser cutter through
Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated.

2. Vinyl Cutting

1. Tested different cut speeds to determine the right speed and power for cutting vinyl.

2. Used mod to run a roland vinyl cutter

3. Printed a parallel series circuit on copper.

4. Will be experimenting with Sand blasting and screen printing in coming weeks>
A vinyl cutter uses a computer-controlled blade to cut out shapes designed using vector graphics. The vinyl cutter is primarily used for cutting vinyl into signs or stickers, but can also be used to cut copper tape into circuit traces and the negatives of vinyl can be used further for multiple 2-3 step processes like screen painting and sand blasting.

After a very informative Recitation with Dr. Neil, I sat for an hour or two to think of ideas regarding my assignment and how i plan to go about it. Went through softwares suggested by other fabbers like Flatfab and also different types of laser machines like waterjet, iron cutting etc.

Day 15
[ Setting Up ]

Day 16 -->

1. Troubleshooting Laptops of my peers installing Ubuntu
2. Editing my Website

Today, its Vigyan Ashram's holiday as its their Village yatra (journey) where all the people belonging to that village meet each other coming from different places, pray as community and invite others to their home for lunch and dinner. So I was invited to one of our instructors place which had a very beautiful and heritage architecture, ate very tradional Vegetarian food. On this occasion they also have faire as community. I went at 11 and got free in evening around 6 because i had to walk from one corner to other and to other and back to Ashram,in which i even visited one Historical place in pabal.

[ Detailing 3d model ]

Day 17 -->

Today:

1.Learnt Parametrics in flatfab
2. Tested and measured the kerb of the laser cutter
3. Started Group Assignment in which I Laser cut (Laser cutter SIL) two different types of Locking system

As I shared with my team, the importance of us learning parametrics , so we all sat together and distributed tasks we will do , which we will share later with each other. I took task of exploring Flatfab and how it can be used in this week. After that, I went through Neil's latest recitation on laser cutting and realised importance of measuring the kerb before proceeding for designing. So I went designed normal square measuring 50-50 cms and after laser cutting (downloaded RD Works and its plugins) , with the help of Vernier caliper i measure the outer and inner offset and concluded the diameter of the kerb is 0.6mm. therefore, now i know how i have to keep offset in my designs that they are exact as expected. Also, in group assignment we decided to make a module board explaining different sizes, forces and speed, locks, curves for reference in the lab , I designed and tried my designs and scaled them up accordingly, which we all decided tp print on monday morning and work on our individual assignments till now as this helped me figure out what fits well to my assigment.

Day 18 -->

Today is Saturday :
1. Learnt how to use Vinyl cutter
2. Fab module on Ubuntu
3. Started Desining my LAser cutting Assignment and Vinyl cutting Assignment

y
1. Well, Our instructor gave us hald day to design our vinyl and we all failed to do so because we were working on laser cutting different locks and press fits. 2. Other half day our instructor Suhasji showed us how to use vinyl cutter , its uses and did whole process, told us about speed, force. 3. While I was designing, my Co-partner of my startup Nishtha Kaushik, approached to me that copper cutting on Vinyl is not coming out right. So we spent whole day giving different trials and errors understanding the best speed and force for cutting copper and that thickness was also one of the concern for copper cutting also we improvised bit more by exporting eagle file ( yes we both learnt EAGLE which was seriously fun for me because i was designing even in Eagle) to autocad and making circuit in the shape of our company's logo,as even i was planning to copper cut so i found it worth my time to learn . We both spent whole day and night till 12 midnight bringing the perfect copper design which was her *series circuit and mine parallel circuit in the shape of Zio's(our startup).Finally even after 12 i spent more time thinking and searching for ideas to vinyl cut and laser cut.

Day 18
[Time to Expand the Makerspace ]

Day 19 -->

I liked this week as it forced me to not sit on laptop whole day designing and working but also do hands on work . I discussed with Yogesh ji my final project and how i plan to improvise it with time and use Shopbot before the given week so that i am able to figure out ideas to improve my final project. Nishtha made few designs which can be used for folding in group assignment as reference for all of us for our projects, so using 2 from that and designing 3-4 of mine i laser cut all of them and analysed which one go well easily for my Maker turban.

[Remaining Assignments]

Day 20 -->

-Learnt Fusion 360 (Simulation beginner) -Made my Laser cutting patterns parametrically on flatfab -Laser cut my turban sample to check its turns -Vinyl cut Parallal series for Nishtha's book as my vinyl assignment

Today, We had a morning story on water, a very interesting facts and sicsussion. Then we had a seminar and discussion on Autodesk applications, parametrics, modelling, feature based softwares etc by Mr.Yogesh kulkarni (ex-autodesk employee). I discovered fusion 360 modelling and simulation. Spent day designing my turban and parallal series. Interacted with young students and taught them how to use lasercutter and Vinyl cutter. Have regional review tomorrow and I have to complete my documentation plus final my Maker turban because the traingle pattern didnt work out, will try again tomorrow.Its 3am, i would continue later.

ATTACHMENT FOR TENSILE STRUCTURE

Day 20
[ Tensile Attachments for Container]

Day 21 -->

Today is Saturday :
1. Whole day in Designing my Expandable Container through sketching followed by Sketchup
2. Took inputs from the young team i have with me, taught them sketchup , photography for now

Its a great day. I skipped my lunch and visited a dhaba (traditional restaurants in india), we ate really amazing food.Again, Sat with those young minds and showed them what all can we do with softwares like sketchup, inkscape, made them familiar with different tensil fabrics, which i plan to use in my project, whole day i was either learning Rhino or designing my 3 D in sketchup , as i attended its Boot camp in Denver, i really liked the way they give freedom to their users to invent new plugins. So i ended up downloading plugins to polish my design.
