Beetle blocks

3D printing.

For a third of this term with Mrs Watson we are going to be 3D printing different patterns and shapes.

Beetle blocks.


I programmed the beetle to repeat the following code 4 times ‘go forward 1 space turn 90 degrees’ and that will make it go in square; However, the beetle only moves in a square it doesn’t trace it, so we get a start extruding lines block. Extruding because it has to be 3D and lines because the only other option is curves and then it just looks like a squircle.


I programmed the dodecagon to repeat the code the same amount of times as the amount of sides the shape has. It is the same as the square except the turn block which is 36 not 90. I didn’t use a green operator block, I just used the calculator on my computer because I didn’t know what the block did due to the odd sign (  /  ). I also found the color block and that’s why the shape is pink!


I don’t need to explain the nonagon that much as its the same as the others just changing the turn again but you also need to set the repeat block to the amount of signs. this doesn’t matter as much though when you are just looking at it but when it prints is will confuse the printer.


The tower was not extremely hard but not very easy because you had to start and stop extruding lines a lot and you have to play around with the X, Y and Z axes a little too. I chose a heptagon because I found it the easiest shape to code. I also used 2 of the green operator block we mentioned before.

My Pattern.

I like my rotational pattern because I think it looks cool and it looks like a pattern I did when I was little on a drawing app.

Hexagon on the X axis.

This shape is almost the same as my pattern, except instead of rotating z by 360/6, we rotate x by the distance each hepatgon is apart, in this case it’s 15. Therefore we divide 360 by 15 so that the beatle will stop once it has completed the last heptagon in the shape.

Turtle Art.

The differences between Beetle Blocks and Turtle Art are :

  1. Beetle blocks is 3D and Turtle Art is 2D
  2. Beetle Blocks also has the Z coordinate and Turtle Art just has X and Y coordinates
  3. Beetle blocks can 3D print and Turtle Art can’t.
  4. Beetle Blocks has a shapes option and Turtle Art does not.

The similarities between Beetle Blocks and Turtle Art are:

  1. They both use block based code and the code looks relatively similar.
  2. They both have fast ways of getting to certain blocks.
  3. They both have a little avatar (turtle, beetle).


Here is one of my Beetle Blocks polygons recreated in Turtle Art:

This was relatively easy to create because all I had to do was copy the code from Beetle Blocks onto Turtle Art.

I used Turtle Art to make my rotational design that I originally made on Beetle Blocks using my polygon.

Changing the size and colour.

Changing the size in Turtle Art will make the line that the turtle is drawing a little bit thicker. These are some photos of making the line thicker:

In the photos I only added ten, but as you can see it actually makes the lines a lot bigger so be careful with your adjustments.

Changing the colour in Turtle Art is easy. To get the exact colour you want is a bit tricky so I have added a colour chart below.

You may notice that 0 and 99 are the same colour, that’s because if we looped this into a circle then 0 and 99 will be next to each other; therefore, they have to be the same colour so that the circle works. Red and aqua are also opposite colours, so in the circle they would be on either side.

In the photos below there are 2 different ways of changing the colour, that I know of. Sorry if I don’t know one.

0 is the default colour

This is 0 and 50 next to each other (opposite)

This is 0, 50, 75 and 25

The other way of changing a colour that I know of, is by getting a number, then adding another number to it to equal a number. These cannot add up to over 100, or the colour chain will be broken. Here is a photo

Rotational symmetry drawing

Here is a screen snip of my rotational design. It demonstrates different pen sizes and different colours.

  1. I created this design by simply getting an arc block and then making an s.
  2. Next I made the line thicker so that it formed a thick s.
  3. Each step I made the line a little bit thinner and changed the colour by 10.
  4. Then I got the yellow diamond shape block so that it would be easier to use the repeat block.
  5. Then I got the turtle right block and used a number block so that I could get the code to divide a sum for me. The sum was 360/6
  6. Finally I put the turtle right block and the little yellow block that the diamond created into a repeat to divide by 6 because the sum was 360/6 therefore whatever we divided 360 by, we want to repeat that amount of times so that the 6’s relate to make a rotational design that has 6 s’


Parts Purposes And Complexities

For a third of this term in design with Mr Colbert we are pulling things apart and upcycling them in to other things. I am pulling apart a drone here is a picture: Image result for Quadcopter Drone CX Model CX 002 DIY

Here is a photo of my drone design with the parts(purple) and the Interactions(red) in my design book:

This is a photo of the insides labeled:


Angus B, Adam H and I are planning to use some of each others parts to make a helicopter; However, we can’t make it fly because one motor isn’t strong enough to lift the helicopter into the air as the motors are only about 1.5cm. Here is a scanned photo of my design:


Here are some photos of our progress:

Sphero blog

For a third of this term in design with Mr Mckie we are using sphero’s. I am working with Leon and his mini sphero. We are learning to program spheros with a block based code and a java based code.

Here are the games we coded:

/\In the photo above/\ The game on the left is the hot potato game and the game on the right is a spinning top.

The hot potato game is when you throw the sphero from one person to another. When you start the code the sphero says: “Time to play the hot tato game.” Then it starts to count to a random number selected by the system, but the players can’t hear it. The sphero is green at the start; however, if you are holding the sphero when it turns red you will be out of the game and the sphero will say: “Ha ha ha”.

The spinning top code is just the sphero turning red if its spinning anti-clockwise and green if it’s spinning clockwise. You also need to manually spin the sphero.

Here are the shapes we coded:

We used roll blocks and delay blocks to get the sphero to form the shapes. We programed a square, a pentagon, a rectangle, a triangle and a rhombus. The sphero moved along the floor, drawing these shapes on the screen. Leon’s mini sphero made them look easy and didn’t even quaver or lean forward when it stopped.

We also made a boat and here are some photos:

/\ontop | underneath\/

Angus doubted that our boat would even float and we wanted to prove him wrong, so first we put only the boat in the water and it sort of worked; by that I mean it didn’t touch the ground but it didn’t float. Then when we put the sphero in the water it floated so it moved a lot more slowly than on land but it still moved. The boat worked until the cardboard got soggy then it turned to mush so we threw it out. Angus also made a boat and it was made of plastic so it worked really well but neither of the boats could carry very much. The cardboard absorbed the water so it sunk faster than the Angus’ plastic boat because the plastic didn’t absorb the water and instead it floated on top. If we put both the spheros in one boat made it go a lot faster, but it was harder to control.

Mini Golf Project Term 3 Farm Theme


This term our design project is a mini golf course and I am working with Leon Ho and Angus Boydell. The size limit for the course is 3 meters long and 1 meter wide. Our mini golf course is going to have a farm theme with a fake gravel path a windmill, a barn, and a drawbridge. Here is my design:

Our goal

Our goal is to make a fully functional golf course with some moving obstacles as well. We wish to have a windmill, a drawbridge and a barn. We want to code parts of our golf course with the LEGO MINDSTORMS coding software. We are going to code our wind mill and drawbridge.


This is our windmill, it’s our first piece of the mini golf course. We used Lego Technic to create the structure and covered it with cardboard right now it is not in a box but will be soon. The windmill has four small blades and a medium motor to power it. It has small legs that hold it upright so it doesn’t fall and the blades don’t hit the wood when it stands alone.


The next part of the build is a drawbridge. the main part of the drawbridge is that it has no walls making it a little bit harder but we may add wall later when we test it if it’s to hard. The bridge has a Lego Technic frame and a wooden base. The bridge is made a draw bridge because of the large motor winding a piece of string and pulling the drawbridge up and down on a three second loop.

Now the barn, we have done the walls and decorated them as well as making a roof and decorating that too. We think that our barn is looking how we want it to look but the bottom of it isn’t even so we will have to figure that out as well. I helped by cutting out the wood and hot glueing it together. Leon and Angus helped by cutting and printing out the decorations for the barn and glueing them on.

Why our obstacles are important:

The draw bridge and river.

The drawbridge was added because I personally think that more mini golf courses should have different obstacles. The drawbridge will probably be the hardest obstacle because it might have no walls meaning that the ball can fall onto the fake water and you have to try again. none of the other groups have a bridge or a draw bridge so it is a unique idea.

The barn.

We think that the barn feature is a big part of our design because we have a farm theme. I think a barn is a traditional farm icon and every good farm has a barn, right? We haven’t started the barn yet, but we are planning on making a classic barn with red walls and a white roof with little windows near the top on both sides. We are planning on building it out of wood but might use cardboard as well.

The windmill.

The windmill is our most classic feature because it is a well known mini golf obstacle. We thought that it would be easy to build but we were wrong. The code was easy but building it is hard because we couldn’t figure out how to get all four blades to point out. After a little while of rummaging around in the back room we found a little cog that had four holes. Then we connected the arms to the four holes in the cog and attached the blades and we have added supports for the Lego brick as well.

The order of the obstacles.

We decided that we should put the obstacles in a literal order putting the drawbridge first because is acts like a driveway over a river to the barn and maybe even a small house off to the side for decoration then the windmill as you get deeper into the farm and then the finish. The reason we only have three obstacles is because we only have a small space to work with.


We haven’t talked about decoration yet but I’ll list some ideas here:

  • small house off to the side
  • little animals in paddocks
  • hills next to the track and a valley also
  • grassland
  • trees
  • flag at the finish
  • fake gravel and grass paths

Final reflection

I feel that our golf course is going mostly to plan and is looking how we want it to look. The golf course is coming along nicely it has dirt in one paddock and a rock wall around the course and the obstacles. Some of our challenges were the drawbridge because we couldn’t figure out whether to put a lego technic base or a wooden base because a lego technic base had holes in it and a wooden base wouldn’t fit well. We solved this problem by putting a lego base on the bottom and some wood on top to make it smooth, then voila we have a smooth sturdy bridge. Something we worked well on was the windmill because we all had a little part in building it, leon got the blades to point out, I got the motor to point out the side of the brick and reinforce the windmill, Angus helped make the legs and he helped code it too. We have all enjoyed this project a lot because it has been a rollercoaster of ups and downs and all of us like building and making things so we have really enjoyed this term’s designs project.

Lego EV3 project (both)

Archie Morgan and I were building a snowplough and here is five photos from all angles. Archie and I were also with Leon when we built the snowplough.

Our next project was a crane which we are still building. Here are are some photos from that project.


What Worked Well

Some things that worked well with the snowplough were the tank tracks for wheels as they would grip the carpet and it would move along with quite a lot of speed.

Things that worked well with the crane was the frame work and the arm i just found the arm on the ground and put a few more long pieces on the end and it fit perfectly so the next day i brought string to school and attached it.


What Didn’t Work Well

Things that didn’t work well with the snowplough were the grab and lift and getting it attached to the front of the block and the code. At the time we were using scratch and we found it unreliable so we tried different things but all to no good use.

Things that didn’t work well with the crane were the lifting mechanism and the motor to do so


What I learnt

With the snow plough I learnt that the tanks tracks were not good at moving on tables instead they were better on the carpet. I also learnt how to code with the lego ev3 software and how to make a robot follow a line using that software.


How could I use what I’ve learnt in the future.

In the future I could program more complicated robots and machines. I could help program other peoples robots if they were struggling.

The History of Australia’s Prime Ministers

Makey Makey Design Project:

I am working on a project with Leon. The project we are working on is a project about the prime minsters of Australia.

Our Design:

We are going to design a cardboard box with the past Prime Ministers names glued onto the outside. We will attach a small piece of foil below each of the names so when you touch the foil it will react with the Makey Makey and follow the code. Here is a photo of my design:

The Code:

We coded the Makey Makey to play prerecorded information about each Prime Minister when you touch the foil.

What You Will Learn:

When you touch the foil you will learn when each prime minister served and also when and where the were born for example:

Malcolm Turnbull: Malcolm Turnbull was the Prime Minister of Australia from 2015 to 2018. He was born on the 24 of October 1954 in Sydney.


Progress Photos

Here are some photos of our project:


Our Goal

Our goal is to make a black box with the names of the past 6 prime ministers on it and when you touch the foil it will say some information about each prime minister. on the sides and back of the box there are drawings that Leon and I drew


Our Struggles

Some of our struggles were:

  • getting the alligator clips to attach to the foil
  • the volume
  • getting the code to react

How we solved it

We solved getting the alligator clips to attach to the foil by sticky-taping the clips to the foil in a way that it would still conduct electricity and react

We solved the volume problem by bringing a speaker and putting it inside the box
