on In Week 9
Electronics.
We learned to solder a circut board to make a light go when it get to a high temputure. We soldered in –
This is the video of me allowing energy to the light from a switch that was imputed into the the motherboard.
Thankyou.
on In Week 8.
Programming.
We learned how to use a micro bit. This is a softwear that allows to code a micro bit to do diferent types of activitys.
In this video it shows how I coded the Micro bit to sing and put on a hart when it get to a certain temputure.
Thank you
on In Week Seven
We learned about Laser Scanning. This is my favourite as it allows you to download data of an physical object by scanning it in and then it creates a CAD design of the scanned object, allowing you to alter the CAD design and even 3D print it.
When learning about the laser scanner we were also introduced to different types of terminology.
There are different types of scanning avalable,
Photogrammetry – This is were the object is photographed from multiple angles, making a photogrammetric reconstruction of the object allowing you to place it in a 3D mesh or point cloud.
Triangulation – This a laser scanner that move around the object, analysing the objects features and usind the light from the scanner to show off the indentation of the object.
Time of Flight Scanners – This is the same as the Triangulation as it uses the light from the laser to outline the features on the objects. Except they use different types of actions and convertion.
This a 3D laster scan that we did using Triangulation.
Thanks for reading.
on In Week Six,
We learned about the CNC Machines. It allows you to cut thicker peices of wood, engrave or cut out any design needed with precision and without the worry of burning the materials, which could occur when using a laster cutter, a more preferred form of cutting and engraving.
To learn how to use the CNC machines we created a design on fustion 360.
Due to computer issues, I had to work with a partner. Together we decided to design a A for us to engrave. We first started to sumulate the CNC machine engarving the A out. This is to show how the engravement will go, what drill peices we need to get the right size.
Thanks for reading.
on In Week Five.
Today we are testing strain and stress on a object using programed simulation on fustion 360.
As you can see we have been given a shape in groups and told to design the shape in CAD. To test the strength of the object and where it experiances high amount of pressure and tention.
The coloured version of the CAD design is showing pressure placed on the object, the red tone is where it is experiencing the highest amount of tention and the blue is the least.
Now its time to put the test into action.
We test them by making two tests. One is to show off a failed test. We did this test to show off a failed structure and to learn how to mesure a failed test out in real life.
How to mesure a failed test.
Tensile testing.
This is a failure analysise of the tention of the different types of materials and structures.
Thanks for reading.
on In week four.
We learned out to make a computerized version of our rocket and put it through a simulation that would show the turbulent and laminar flow of wind and how it would act on our water rocket.
This is the design of the first rocket.
We then designed a box that molded the rocket, this would then gave us a chance to see the area around the rocket. Inculding the action of the turbulent and laminar flow of wind round the rocket.
This program is called “Ansys”.
Thanks for reading.
on In Week Three.
Rocket analyis.
We learned that we are going to build our own rockets using pressurized water as thrust to fling it in to the air.
To ensure that the model stays in the air for the maximum amount of time we will have to reduce air drag and ensure that its aerodynamic. This will be through testing out different noses. Different types of bodies, adjust the wings or stabilizers to make sure that the rocket doesn’t flow off course. Work out wind speed and direction.
we have to take in –
We have to take all this into considration or the rocket won’t be able to get enough hight and it will fail.
To get an idea of the process and the expectation we should have for our rocket, we started to look at. Videos posted by NASA when they did this experiment. Look below for the video.
Using the wind tunnel, we are going to measure the lift and drag on the model to see how efficiently we can send out pressurized water bullet rockets to fly up in the air. The lift and drag will be determined by how aerodynamic the rocket is
Wind tunnel.
These are the results from the wind tunnel, using different nose shapes to swich up the different types of air flow round the rocket. This will adjust the drag force and lift.
Using this information we are going to make rocket nose using the first profile.
This will be put into place on the group website, move there for more information about the launch of the rocket.
Thanks for reading.
on Plasma Cutout Box.
In week two, we were shown how to make a box out of steel and use the plasma cutter to cut it out.
We made the CAD Design in Fusion 360.
This is the step to step intructions of how we made it:
5. Use extrude and within the mesurments input the chipboard setting to create the correct thickness.
6. Select the base and add the flange on two sides of the bases. use the Parameter, hight, to imput the mesurments.
7. On the flanges that you have just made. You now need to add sides to the flanges. The added sides will go on the side of the orignal flanges. These will have a width of 30mm.
8. After adding the sides on the flange, press the base and add another set of flanges to the other sides. Do the same to this sides as you did in section 6.
9. Unfold the box and cut out 5mm circles on the four corners. Then on the gap on the cut out circles, create a 30 deg angle on the added 30mm width sides on the flange.
10. Once thats done, fold the box again. It should then look like the video shown below.
on This was to test out the website and to see if I can imput outside media in to my website.
This was a video that I used for a previous video. I made my phone in CAD, I then use that model to create myself my own phone case in which I 3D printed.
