* प्रोजेक्टची माहिती :-

   १. three phase change over :- या मध्ये                        थ्री फेजचे कनेक्शनची वायर घेतली. पुढे काम करताना येथून बंद केल्या नंतर काम करू शकतो.

   २. three phase changer :- या मधून three phase चे कनेक्शन दिले. या मधून तीन फेज पैकी

एक लाईन घेवू शकतो.    

   ३. change over mcb :- या मध्ये दोन कनेक्शन घेवू शकतो. मी three phase व genaretor चे कनेक्शन दिले. असे दोन mcb बसवले. दुसऱ्या mcb मध्ये single phase व पहिला mcb comman केला.

   Tubelight

* Aim :-    Working and connection of tubelight and trouloieshooting methods                                                        * Tools :-   Tester,Series , testing lamp , pliers , wire stripper

* Materials :-  Wirescis sqmm , insulatien tape , ballast ,  ,starter,tube holder 

 *  Procedure :-   We brought a tubelight  w`hich was not working, We tested the supply wires of the Tubelight ,     We Testedthe tube using a series lamp, We checked the connections  referring from a circlit diagram , We Troubleshooted the tube ,starter and ballast .

* Observation :- (1) We checked the Tubelight,s  tube  first it successfully  passed the Trouloleshooting  test .

(2)Secondly we checked the starter, it was also  working in a good condition.

(3)Thirdly we checked the ballast which was also working.

* Conclusion:- After 1 hour of work we concluded that the problem was with fanlty witring

D. O .L.  Starter

* Aim:-  Working and Connection of a Motor Starter

* Tools :- Tester, Series Lamp.

 *Materials:- Wires.

*Procedure :- (1) We took a mechanical starter from the arfificiai pond.

(2) We opened it and separated the parts and stadied them carefudly .

(3) We brushed  the contactors as a carbon residue forms a fter long times of use .

(4) We saw the thermal relay that contains a  bi-metal Sfrip.

*Observation:-  While testing the no-volt coil we saw that when we passed the current through the no-volt coil the coil turned into on Electromagnet.

*Conclusion :- We also concluded that we can use a MCB  instead of a Motor Starter. 

          Motor Rewinding

Aim :- Riwinding a Motor

Tools :- wire cutter , spanner, screwdriver

Materials :-Copper wire, Cotton Thread , Varnish , PVC Paper ,Capacitor,Screw Connectors Sleeves (1mm and 3mm)

Procedure :-  1 Hp Motor

(1) We Disassembled the motor according to the earlier motor practical

(2) The important earlier motor practical

(3) The  Taul was the coil was Shatcriated

* Observation :- (1)  while filling the coil we should fill it in any same direction otherwise the coil will not work      

(2) While fillng the coil there should be no damage  or any type of pressure on it doing that will damage the coil and you will have to Rewird the motor again .

 * Conelusion :- If the coil gets short circuited at any point you will have to rewind it again .

* Contacters :- Pices of copper  which connect to the main supply

* Thermal contail switch :-Contains a bi-metal strip which on reaching a desired  current  bends   and disconnects from the maj supply.

  *   We were in  fab lab  moking a lanreth for Diwali

 *  We  made a  bief  sketch  on  the  book  and  then we findlised our         diesian

*  Then we downlaaded a  box  form the internet then  we searchedfor a pattern

 *   After downioading the pottern we placed it on the box sidel and then we cultad it accordingly

*  We were  making a magic lanten  because diwail  is coming  clpser and we warted  ro  make  something  that  woutd  fit in this generation of the world .

*       Something  whidn would  be smat and is capaie of doing  tasks on its own on a commound

*  We had two groups :-  (1) Arduino (they looked  about how to make the      lanten smate )

                       (2) Fab Lab (we look about making the lanted look modem )

We made a small devghar for Ganpati.
We used the Laser Cutter machine.
We used Inkscape for designing and saved the file in a .dxf format.
The Laser Cutter machine understands .dxf format language.
Then we opened the .dxf file in a software called "RD Works" and then downloaded the file to the cutter.
We positioned the laser point and started cutting the given file on an MDF sheet.
You can define the speed and power of the laser.
The Cost of the small temple in Rs.120.
