Project Development



What tasks have been completed, and what tasks remain? 

Initially main aim was to make Basundi on solar reflector with food grade material that should I can use as actual on feild working model. 
But to include all process I made working model that will make Basundi but without food grade material.

Major completed project tasks are :   

Did project survey and finalize actual need.
Made final project prototype sketch
Drawn design in 2D and 3D.
Printed project  parts on Laser cutter and 3d printer.
Inserted Input /  Output devices inside for automation and efficiency.

As per objective remained part is to make prototype using food grade material, rest of all tasks are covered.

What question need to be resolved?

Up to yet it is remained to decide the value of current required at different amount of milk.
It is remained to check its reliability
We have to increase water evaporation capacity of system so that we can put more amount of milk in that

   
 
What has worked? what hasn't?

Mainly this project has two parts one is modular and other one is Electronics. Under modular first decided to use big spindle with high torque motor and aluminum pot but that covers only few digital fabrication processes. So decided to go with acrylic material for some of part that doesn’t comes under food grade. For motor initially tried with small 100 RPM geared motor but it moves faster that unsuits for my application so now using a wiper motor that gives around 50 RPM speed.


Inside electronics to check milk viscosity I tried first level sensor as milk level gets down and down after heating, But again its not giving a proper results, it’s based on assumption. So now I put one current sensor in series with motor that gives input to controller when speed gets down when liquid goes denser and denser.


What will happen when??


Initially height of motor assembly is more so it gets difficult to stir it wel. So that I changed Motor assembly height and by default mechanism of stirring process. It happens when all project is at middle stage. Same time I come to know that level sensor doesn’t works wel for getting viscosity of milk so I  replaced current sensor instead of level sensor.


What Have you learned ???


During the project and assignments I learned so many things. Some part like design,web page design are totally new for me. Some are as follows :


Project management, Time management and Market Survey are the main thing I learned
Because I had very short time to complete project but I had started market survey from the beginning of fabacademy.Instructors suggestions helped me to do good time management.I also learned,
Design software: Inkscape,123 autodesk,Tinkercad , 123D make , Solidworks ,Eagle and machine software.
Programming : HTML, CSS, Embededd C, Assembly Language etc
Intellectual property
Machines and handskills: Soldering, Laser cutter, 3D printer, Scanner, Shopbot , Modella, Vinyl cutter, Power tools , Molding and casting etc
Market Survey


Documentation during Development:

2D design and cutting
Input
Output
Electronics design
Computer controlled machinning
composite


Demand vs supply side management :


The product to be deliver, will be prepared at the time of order, so no money is stuck as stock and it enables cash-flow. Building time for product is short so thus option is possible. Also this one is open source design so anyone can make this with contributing cause.


Project Plan was:

Make a prototype – Fabricate – Test is on solar cooker  – Make it using food grade material – Test it on the field












Spiral development:


This project is with social aspect considering conservation of fuel , health  and cost. It’s necessary to be always in contact with Hotel Propriaters to rake trials and show actual use of this product which reduces fuel and human efforts . In other side have to make chain network of these  peoples  for mouth publicity of a product . If anyone wants to improve design or any part he can do this and use commercilize spread this. Social media and web are options to get income with reaching peoples,find them ;set them as a trendsetters and give some kits to them in exchange of spreading words. As more peoples see the system working, more people will wonder and get interested in the project,not only for purchase but for funding and investing.
