Trials on Dome Dryer

Trials started on  ’Dome Dryer’. Dome dryer is, dryer  based on natural air convention & dehumidification. This drying concept uses geodesic dome shape to generate natural air movement for faster drying. Initial trials ,showed that it can be effectively used in winter season  This dryer will be very useful for drying of high value fruits , vegetables & spices with maximum colour , flavours & nutritional value retention.

Initial trial have shown encouraging results on Mint leaves , ginger , onion etc. We are working on testing its effectiveness in different agro-climatice regions / seasons and standerdizing it for further dissemination.

Rice De-husking machine – Lab trial report

As a part of technology development for producing brown rice at domestic level, we successfully completed lab trial. The said machine is motorized with 10 Kg/ Hr de-husking capacity. This machine is very useful for Rice growing Farmers, SHGs , rural youth for starting domestic level brown rice production. For details on lab trial please follow link given below –

Sanitary Pad disposal unit.

Vigyan ashram has successfully fabricated & lab-tested sanitary Pad Disposal / Incinerator unit. The said unit is named as WOMA-VIVUS-FAB incinerator. Details on this  as below-

SP BURNER (1)

VA FAB-LAB has contributed for designing & development of this unit. Your comments / feedback will  help us further to improve it.

New prototype design of Hand Operated Rice De-husking…..

A new prototype design is made for fabricating Hand operated De-husking machine. This low cost machine will be useful for preparing brown rice (non – polished rice as  traditional rice pounding ) without grid (electricity) power. Dr.B.S.K.K.V , Agriculture B.Tech students Sanath Prabhukhanolkar and Nilam Shirsat worked on this prototype designing during their summer training at Vigyan ashram campus. For more information you can contact Mr.Anil Gadhe – aanilgadhe@gmail.com 

LDR based light Controller

LDR (Light dependent resistor) based light controller was designed in the FABLAB. It is very useful to operate street lamps.

There is no need to monitor or operate the lamp separately as it is operation is depend on the ambient light.

It change the state of lamp from OFF to ON  when dusk occurs & the vice-versa.

Please find the design document below.

Water Pump Controller/Alarm System

Water Pump Controller/alarm system is fabricated in Vigyan Ashram.Purpose of this system is to turn off the motor when water level close to the full. There is also another provision in the same circuit with few changes which blows the alarm when water level reach up to the sensor level. One can easily serves the purpose of water saving with this device.

It is very easy to built this circuit by following the given primary document below.

Solar Street lamp Installation & Maintenance Manual

A manual was design for the installation & maintenance of solar street lamp.The purpose of this manual is to train rural youths so that they can install,maintain & repair solar street lamp themselves and by means of this they can start earning  at their place itself. This manual is going to used by different trainers across Maharashtra state.One work shop was also done succesfully by Vigyan Ashram in the Selu village of Wardha dist.

Manual contains following things like:

• The basics of solar energy,
• Tools & components required for installation & maintenance,
• Calculation for finding load,battery capacity& solar power,
• Installation process & steps of maintenance.

Apart from this it also contain the information about the different types of solar energy based devices.

FAB 8 Conference

The FAB 8 conference, an yearly meet of all the fablabs, across the globe, was held in New Zealand, Wellington at Massey University. Vigyan Ashram, also being the first fablab, had its presence.

Find herewith the presentation (in .pdf  format)  we made at the conference. While the event is over, we wish to welcome our readers to provide us with feedbacks on this. They will be very much helping us for Fab – 9, to be held in Japan in year 2013.

Low cost, qualitative Hearing Aid

Introduction –

A very special note about human-ear is that humans do not posses control over activity of this vital organ. An incidental sound has to be heard by a human being unless she /he is sleeping or unconscious. Ofcourse there are artificial ways, but natural. However, another fact is that everyone of us may have different capacities of listening to the same sound.

We range from people who can listen to even a slightest noise to people – completely deaf. This particular document intends to connect a technological solution (to this problem) and the socio-economical (and why not political) conditions in India (and countries alike). We encourage the readers to implement the device and/or provide us with their inputs and/or observations.
