Fab Lab 0.0 to Fab Lab 0.4 - Learning from running a lab in an Indian Village

Abstract
Fab Lab in developing countries have different operational problems. Within the constraints of resources, they have to prove effectiveness and the impacts of utilization of Fab Lab for their community. Vigyan Ashram (VA) Fab Lab was started in Pabal, a small village in western India with the support of MIT and Fab Foundation in 2002 and has been operational since then. It was started in a small 150 sq.ft tin shed with few machines. This lab is used by rural youth mainly, school dropouts. As the utility of the Fab Lab was experienced by the community, the lab grew in size. It saw three phases of expansion in terms of physical space and machinery. This paper is presenting challenges faced in this evolution in terms of machinery, inventory, infrastructure, manpower and projects. It is also presenting different approaches tried by VA to overcome these challenges.


1          Introduction
Vigyan Ashram (www.vigyanashram.com) is located in a drought prone village Pabal, which is approximately 60 kms from nearest city, Pune in western India. It is engaged in training rural youth on various rural technologies. VA helps these youth to start their own micro-enterprises in the villages. Dr. Kalbag, the founder of the ashram, was a firm believer that instead of giving ready made solutions to the poor community, we must give them means to find out their own solutions. Dr. Neil Gershenfeld (Center for Bits and Atoms, MIT) first visited VA on the 27th January 2002 and stressed the need to use advanced technology to find out solutions to some of the pressing developmental issues in the community. Through this interaction between Dr. Kalbag and Dr. Gershenfeld, the first Fab Lab outside MIT was established, hence the title Fab Lab 0.0.
The VA Fab Lab end-users are mainly rural youth with minimum qualification and computer literacy. Machines in the Fab Lab are often too sophisticated for them. There were challenges in terms of the quality of electricity, dusty atmosphere and high ambient temperatures which caused troubles in the  appropriate functioning of the Fab Lab.  In spite of all these odds, VA Fab Lab could sustain its momentum. This paper documents the learning and difficulties faced in each of the operational areas. The operational areas are divided into machines, man power, education, projects, camps and community outreach, funding and support from the Fab network. It also documents alternative strategies found by VA. This learning may help new Fab Labs setup in rural areas of developing countries.



2                   Fab Lab Machines

It is often said that the Fab Lab is not about the machine. It is about the makers and them making things! But tools for digital fabrication differentiate Fab Labs from maker spaces and tool rooms. There was initial hesitation at VA about using digital fabrication. Teachers and students were finding it convenient & faster to use traditional tools for making things. Use of computers for drawing design was taking considerable time due to lack of practise and skills. Further the originally installed Fab Lab machines were not found suitable for making projects involving metals, as required for example in making improved agricultural tools etc. Table 1 presents a machine wise analysis of the problems faced in the machine operations. Overall learning curve of VA fab lab was long to master digital fabrication. Now, VA fab lab is comfortable with these tools and have become an integral part of Vigyan Ashram programs.
Machine (year of installation)
Applications
Frequency of use
Technical Problems faced & solutions found
Outcomes
Vinyl Cutter (2002)
Screen Printing, Name Plates, flexi-circuits for wearable electronics.
Good
Not major issues other than software re-installation.
Two of VA alumni started their micro enterprises. They have purchased machine and providing letter cutting service. 
Laser Cutter (2006 & 2016)
Acrylic / thin plywood for casings, sign boards
Good
- Severe problems due to bad quality of electric supply, needed replacement of controller and laser tube. Normal earthing did not work due to dry & rocky soil so chemical earthing was used.
- Cost of acrylic and MDF sheets was overcome by using packaging cardboard for practice.  
Most loved machine! Many projects and all electronics casings made on this machine.
VA wrote a manual on ‘How to do earthing?’ for laser cutting machine based on this experience. 
Got additional CO2 laser machine from corporate donor.
Plasma Cutting (2007 & 2016 )
For making Agri tools using metal.
Not used
The machine never worked since beginning. There were issues with critical parts. Other issues related to electricity and voltage led to its failure.
There are lots of applications in agri tools and solar using sheet metal plates.
Therefore in consultation & support from local metal fabrication industry, VA has recently purchased new plasma cutting machine.
CNC Milling M/C
PCB making, Moulding & Casting
Average
- End mills are expensive. Therefore unless essential (e.g. fab Academy), VA students used traditional PCB making methods.
- Availability of SMD components was problems in the past. Making through hole PCB was difficult on CNC milling. Therefore traditional PCB making methods were used.
- The use is limited to Fab Academy projects and in the Fab Camps.
- Moulding and casting is mainly used for training.
3D Printer (2014, 2015, 2016)
Science project, Jewellery design, casings, prosthetic project.
Good
- VA tried to make our own 3D Printer using D-I-Y kit. But it did not work.
- Then VA purchased PLA 3D printer from local start-up. It had several maintenance issues, the company closed down. VA fab lab could not use it any more.
- VA have purchased ABS printer from another start-ups. It is performing satisfactorily.
- All this experimentation was funded from the awards received by VA.
Now 3D printer is working fine.
VA team are working on making open sourced prosthetic hand in our lab.
Recently, VA have got 3D printer from corporate foundation for secondary school.

3                   Fab Lab Staff

Vigyan Ashram (VA) is a voluntary organisation. There are challenges in attracting qualified persons due to limitation in salary, limited resources and remote location. Therefore VA employed technically qualified freshers from surrounding areas and trained them on the job. They were encouraged to learn digital fabrication. Bright and committed members are sponsored to Fab Academy course. Sometimes, the trained person leaves the job for better opportunity. It has impact on VA lab operations due to such changes. But over a period, VA has many trained users of the lab. Now many of ex-VA staff and students have joined other Fab Labs. As such the efforts in training of youth are benefiting the Fab movement in India.
Volunteers / Interns: VA being a social organisation attracts many youth from India & abroad for volunteering. They have worked with VA Fab Lab in durations of 1-6 months. VA used their expertise to streamline some of the processes of the VA Fab Lab. Every year, about 4-5 volunteers contributed to the VA Fab Lab. These volunteers helped VA to complete projects, develop curriculum, conduct Fab camps and solve maintenance issues of the equipments. Beside volunteers, students from MIT/Fab Foundation introduced new tools and techniques. Realizing contribution of volunteers, VA has developed modest residential facility for volunteers. There were few volunteers who took sabbatical from their corporate job and worked in VA Fab Lab for a few months. In short volunteers are important strategic contributors in the VA Fab Lab operations.

4                   Education 

Education is the most important activity of VA Fab Lab. Students of VA are the primary users of the lab. They are youth in the age group of 14-20 years and have studied up to secondary school level. VA uses pedagogy of involving student in ‘Socially useful productive work’. The work activity is selected in such a way as to introduce curricular concept to students. Students provide various services to the community as a part of their learning. Services include agriculture, fabrication, electrical fitting, food processing, repair and maintenance, construction, etc. Digital fabrication tools become addition to this bouquet of services. 
VA has developed a program to introduce them to the fab lab environment. Following programs are conducted for new students:-
1.    Fab camp – To introduce machine operations in 3 days sessions. It involves introducing drawing software, operation of machines, printing of job & documentation. There is also small introduction to Arduino and micro-controllers.
2.    Think like an innovator – A manual to select project ideas and work on them. It is available on http://www.navazkarim.com/works/think-like-an-innovator/
3.    FabEd – For secondary school children, VA has started a FabEd program. It is designed to link fab lab activity with curricular areas. The process of conducting FabEd activities can be found in the following link:   https://drive.google.com/file/d/0B_Jk2xLqAXjcVmNydHRSc0EtVnRGOWNqSzdJLURLSHQ4MW1R/view?usp=sharing
4.    VA is working with 122+ rural secondary schools and implementing ‘Introduction to basic Technology (IBT)’ program. In IBT program, students learn while doing for 20% of the school time. These schools have conventional fabrication & electrical tools.  They also have computers. These schools are encouraged to work on design software and use VA fab lab for creating from their files. Projects on automation & microprocessors were introduced last year. This year, VA has planned to introduced electronics and 3D printing by conducting 40 camps for secondary school children targeting 300 students.   
5.    How to start Fab Lab : VA has designed and conducted 3 day workshop for organizations willing to start Fab Lab. It was successful and many new labs are opening up because of the training.
6.    The new programs are announced and communicate through social media. Schedule of Fab events are on : http://www.vigyanashram.doattend.com/
7.    On an average, VA fab lab is used by approx. 100 + youth every year.

5                   Fab Projects

Fab lab environment helps to generate new ideas from VA students. Many projects ideas were born at VA Fab lab and developed into prototypes. There ideas have great potential. A few ideas, VA could not take it to the logical conclusion. Students, however, learned very well through these projects. It was very good academic exercise. But harnessing the good ideas to its full potential remains the main challenge of VA Fab Lab. Some of the good projects on which VA has worked but remain unfinished are listed in Table 2These examples show the variety of projects that were handled by VA Fab lab. VA has invested time and resources on the projects. They could have benefited Fab lab and society. Such unfinished project remains main worry of VA fab lab.
On the other hand, VA has been successful in completing many other projects. Members have used traditional fabrication tools like arc welding, CO2 welding, lathe machine, electrical motor rewinding unit, etc., along with tools for digital fabrication. VA has a food processing unit, poly-house, dairy, goat farm, poultry, traditional fabrication shop etc., on our campus. In true sense, VA can make almost anything on the VA campus. The completed or near-completion projects are listed in Table 3.
Documentation & report of all projects are shared on the blog www.vigyanashram.wordpress.com

Milk testing Device. (2002)
VA got initial circuit & program from MIT. It was reproduced in the lab. It was able to detect difference in the quality of milk samples.
VA team could not carry out the calibration of the circuits between good milk and spoilt milk. VA could not get technical report to make the efforts successful.
Projects still remains relevant.
Admin Device for Teachers  (2005)
To help teachers to maintain students records.
A device was made in the fab lab to record attendance of students.
Only one device was made. It worked and was tested in Pabal. Some more refinement was needed. But the person in-charge left the job.
There is no more need of the handheld device due to availability of Smart phone and apps.
Low cost weather station(2006). Unlike commercially available weather station this device measures only customized parameters necessary for pest management.
This was made with the help of volunteers from Engineers Without Borders.
One device was made. Refinement was not done. After first prototype, new person was not able to take it forward.
Still relevant and required.
Leaf Wetness duration sensor (LWSS).
This need was expressed by grape growers. They want to know duration of dew wetness on the leaf to control pest attack.
Prototype was made and tested in the lab. There were issues in the consistency of the readings and sensor.
Two engineers worked on it for almost a year but could not take it to the field.
Project is still needed. It requires competence and patience in taking solution to the field.
Bull Controller -
To control bulls in bullock race.
Idea is to make remote control reins to control bull. The circuit was made and it worked as prototype.
Did not get high torque motors to pull bulls reins. Therefore not tested in the field.
The person doing the project lost interest and it remains incomplete.
Task remains incomplete.

6                   Peoples Involvement

VA is located in a small village and farming is the main occupation of the community. There are regular visitors to ashram. Through open house exhibition and demonstration, community become aware about the potential of Fab lab. Now, they come with their problems and ideas to VA. These are their needs and they are willing to pay for solutions from the lab. This helps VA, to work on real life problems. Following are few examples of projects done on demand from community :--

HTP spray pump attachment to a two wheeler.
For spraying pesticides in small farms.
High rise fruit cutter  / Fruits on thorny bushes
Simple clutch and cutter attachment that can we fitted on any rod or bamboo.
Mahua collector
To collect flowers falling on the ground and getting spoilt in the soil.
Terrace dryer -  low cost dryer
It uses basic drying principle and customised to local vegetables & climate.

7                   Fab Network & Fab Conferences

In last 13 years of Fab operations, there were many disappointments and frustrations. Sometimes, nothing seems to work at VA Fab lab. The problems range from electricity to laser & computer software.  Strength of network helps in overcoming such anxious moments. Visit of MIT students from Fab Foundation helped to overcome technical difficulties. Most importantly, VA team learned a lot from attending Fab Conferences. These conferences and workshops helped VA team to learn from other labs and implement the ideas at VA. Attending Fab conferences abroad by village based institute are not considered priority by many donors and foundations in countries like India. Therefore attending Fab conference remains a challenge and it has became possible so far due to support of Fab foundation. It can be concluded that investment in attending fab conferences greatly contributed to human resource development at VA.

8                   Funding

VA is working with support of foundation and individual donors. VA mainly caters to student from socially and economically disadvantaged community. Foundations are mainly interested in funding skill training which will give youth immediate livelihood. Long term and capacity building initiative like Fab Lab goes into lower priority activities.  Fortunately, VA got initial support from MIT for machines. Department of Science and Technology (Govt. of India) supported salary of one Fab Lab engineer & a small financial support for recurring cost.  Other than this, VA-Fab Lab has not got any significant financial support from 2002-2014.
VA-Fab Lab operation is funded by combination of following –
i)              Government (Dept of science & Technology) : 20 % of total cost of operation, mainly for salary of  Fab Engineer
ii)             Fees of students: 40 % to cover mainly cost of project materials.
iii)            Private donors and foundation : 10 % for machine up-gradation
iv)            Projects against orders :10% (fees paid by the customers)
v)             Fab Foundation  : 20% (scholarship for Fab Academy students and Fab conference)
With the success of the Fab projects and awareness about the Fab Lab increased, VA started getting support from foundation to upgrade its machines and replenish its inventory. In 2015, VA got Laser cutting machine from corporate foundation and others.
In 2012, Government of Maharashtra sponsored establishing Mini Fab Lab in Pune. At present, Govt of India and State Government of Maharashtra are planning to establish tinkering labs, innovation centres at block & district levels. VA fab lab is regularly visited by authorities for consultation. 

9                   Way Ahead:  Fab Lab for Appropriate Technologies

In last 13 years of operation, VA Fab Lab is becoming focussed on Appropriate Technologies (AT) for rural and under developed regions. Mr. Schumacher (1973) wrote a book ‘small is beautiful’. His ideas give rise to concept of AT. AT technology solutions ask for:-
1.       People’s involvement in finding solution to their problems.
2.       Solution which is environmentally friendly and uses local resources.
AT movement was at its peak in 1980. It has lost its momentum due to the following:-
1.       AT solution was seen as inferior technology solution.
2.       AT solution requires local skills and workmanship to make it locally.
3.       AT solutions were difficult to replicate and hence its impact remains limited.
Fab Lab is for people to find solutions to their own needs with local resources. From the experience of Fab Lab at VA, it can be said that Fab lab can provide answer for the shortcoming of AT movement of 1980’s.
1.       Digital fabrication and computer cutting machine will reduce dependence on the local skills for reproducing the product.
2.       Sharing of designs and files become easy in the fab lab network.
3.       Fab network will make it is easier to work with the other labs with similar interest and problems.
At present, Vigyan ashram is concentrating on AT projects in the following areas-
1.       Precision agriculture
2.       Prosthetic solutions
3.       Clean Energy solutions

Design Innovation Center (DIC) : VA has started DIC to overcome the problems of incomplete project ideas. DIC started a course on design for graduate students. They will work in the Fab Lab for six month and learn design concepts by working on real life projects. The project will be evaluated on the criteria of user experience and field testing. They will get academic credit from Savitribai Phule Pune university (SPPU). This initiative started in March 2016 and now has ten engineering students working on their projects.

10              Conclusion:

In 2002, Journey of VA fab Lab started in small tin-roof room of 150 sq.ft. In 2005, Fab Lab was shifted to slightly bigger room of 800 sq.ft. In 2011, Fab Lab was shifted to well-constructed workplace of 1000 sq.ft. In 2016, VA fab Lab shifted to 2000 sq.ft place. The journey is described as Fab Lab 0.0 to Fab Lab 0.4.
The journey was full of challenges and fulfilment. Lots of questions are asked about sustainability of the Fab Lab. Anything which is useful and needed by the society, sustains itself. VA Fab Lab survived and grew up in last 13 years. It became possible due to support of various stakeholder and Fab network.
