- Task 1: Isometric and Orthographic Projections In this task, we had 3 drawings: 1) Orthographic projection of Tetrahedron. 2) Isometric View of a Nut. 3) Isometric View of a machine part. for drawing and learning about them. I didn't face much difficulty in this and could understand how the drawings could be drawn easily. From the part 1 of the task, I learnt about how to do orthographic projection of a tetrahedron.
In part 2 of the task, I learnt about isometric projection and its creation from orthographic projection.
In part 3 of the task, I attempted to do the Isometric View of the machine part shown, but I got stuck in the thought about how to do the curves in the drawing. The drawing was a bit complex, and I didn't find a way to do it yet. 2.Task 2: 2D Drafting in CAD In this task, I learnt about how to do 2D drawings of platonic solids using fusion 360 software.
3. Task 3: 3D drawing At first, I attempted to draw 3D drawing of pentagonal pyramid from 2D sketches but couldn’t finish it successfully as I didn’t understand how to draw 3D models from 2D sketches. But then, I learnt about the 3D sketch option which can be used to create 3D sketches and so, completed it successfully.
Then, I also completed the 3D model of hollow cylinder in which I learnt about how to extrude a plane to create a solid and how to remove parts inside it.
Then, I performed part 2 of this task which was about 3D model of hexagonal pyramid over a cylinder. Here, I learnt about how to extrude closed surface and also how to remove undesired parts using plane section to create the hexagonal pyramid.
After this, I finished part 3 of this task which is to draw a 3D model of triangular prism placed on a square prism, in which I learnt about extrusion of plane surface to create a solid
4. Task 4: Design, Assembly and Simulation In this task, I performed the rapid 3D prototyping of hinge joint, in which, I learnt about how to create different components and how to assemble components. At first, I was facing many confusions and problems regarding this like how to draw different components separately and assemble them together, but then, I found out the way to do it and therefore successfully completed the task.
5. Task 5: 3D designing of ball and socket joint In this task, I performed the 3D prototyping of Ball and Socket Joint, in which, I learnt about how to make different components and how to assemble them. I also learnt about how to remove unwanted parts properly and how to extrude only the required planes.
6. Task 7: LED on a Breadboard In this task, I rigged up a simple circuit for lighting of a LED using a breadboard, wires, a battery. I learnt about testing LED using multimeter. I also tried stacking of LED's and saw that their brightness decreased. Here I also used the breadboard power supply to get power supplies with different voltages and tried finding the resistance values that has to be used in series with the LED.
7. Task 8: Transistor as a switch Here, in this task, I learnt about how to use the transistor as a switch. I built the circuit using a npn transistor, resistors, wires, switch and a voltage source and looked into the working of the circuit.
8. Task9: Flash an LED using a transistor This task is about blinking LED's using transistors, resistors and capacitors. Here, I learnt and experimented about how the rate of blinking changes with change in values of capacitors and resistors.
9. Task 10: Darkness detector using LDR In this tas learnt about how a darkness detector and light detector circuit can be made using LDR.As we kept on varying the intensity of light, the LED kept on becoming dimmer or brighter depending on which circuit we were using.
10. Task 11: Convert your drawings on paper to CAD In the part 1 of this task, I performed the 3D modelling of an isometric projection picture using Fusion 360. Here, I learnt about making a cuboid and cutting it as required to make the required 3D model.
In part 2 of this task, I performed 3D drawing of isometric projection of the given image using fusion 360. Here, I learnt about how to make attached components and extrude them in simplified terms.
Here, I tried to complete the part 3 of this task but could not complete because I had confusions and had difficulty in understanding how to do the 3D model. 11. Task 12: Simple soldering practice In this task, I practiced soldering using a soldering gun, a soldering tin on a copper board. I learnt to solder an IC and also to solder a stripped resistor. I also learnt about safe practices about how to maintain the gu also learnt that we should place the gun only on the holder and nowhere else. I also soldered another IC on my own. I faced problem of short circuiting, so I used a copper desoldering braid for desoldering.
