1. Making Charcoal By Bio-waste
Aim :- Making charcoal with the help of biomass.
Requirements :- Tin barrel , tin pipe , match box, Bio waste (5 kg) ,wheat power (500 gm)
Procedure :- We take a tin barrel and we make holes on tin barrel at the part of side surface at middle we put holes after that we put bio waste in the barrel . We burn the bio waste in the barrel slowly slowly and we cover the barrel with the help of tin plate and put the tin pipe at the upper surface at the cap surface .We burn it for three hours after extinguish fire we remove the charcoal in it and after some times we make a powder of charcoal and put atta for stickyness for giving shape also .we mix charcoal and aata .And we put it in sunlight After then we give it shape like a ball,cube etc and do packing .
Observation :-
1)When we burn it we should keep tin plate because if we not keep it , it will be burn fastly
2) When we burn it the smoke was coming out of that barrel it is harm full to us for breathing we stand longer for the barrel because bio waste give`s carbon dioxide which is useful for plants .
Conclusion :- I learn about how to use charcoal in our daily life .
2. Safety Rules 1)Having rubber shoes when we working at electrical work.
2)when we join 2 wires we have to use plier. 3)Before we touching any electrical wire we want to test with a tester.
4)Main switch off before doing any electrical work

6. JOINT`S
Aim:- exploring different types of wire joint`s Requirement`s:-plier, stripper and wire.
procedure:-we saw different types of joints .
1) Union joint :-the wire are crossed positioned to make along and twist or bend in each wire at one end of the wire is unrapped and then the other and four or five times around the straight position of each wire are pressed down as close as possible to the straight position of the wire.
2) Married joint :- The married joints used for joining multi stand cables. The wire re-unstranded and then interlocked with the wire of the other cable and then married (Twist) together finally being soldered.
3) Simple joint :- simple joints used in house wiring and while doing simple wiring work.
4) Britania joint:- The britania joint is a from of electrical joined use for base over head wire where great tight strenght is required the two wire are each tinned and then and each have a short shoulder are then round together with tinned wire before the whole.

Plier, Hammer, Nut & bolt, Cutter, Tester, Stripper, Srew driver,
1.5mm wire, Test lamp Milimeter, Spanners, Sensors & Circuit.
Pre - planning -
I took help of ethernet and made blue prints of the whole diagram to
know wiring. After knoqing all the bugs we bought the new
material,sensors & circuit. While working on wiring we took help of
our sir.
Procedure - We checked out wiring of indicator, mcb & motor connection. Then drawn circuit diagram. By
using multimeter we checked continuity of motor and it was on the
negative result. Then we removed motor. We checked the whole motor ans
changed the wiring. Also repaired safety door button and bought new
sensors and circuit. After these trials we fixed the circuit in machine
it started workimg properly.
Observation -
I learnt new type of wiring qhich would be helpful for me in my further
work. Most of the work depends on wiring this what i learnt from this
project.
