Taking apart old devices

these few weeks we have been able to pull apart old electronics and see what makes them work

I chose to to take apart an old five dollar mouse with an expose wire

Here is the design



here are some of the photos

Here’s what it looked like originally


First thing i did was take out the screw at the bottom and that releases the mane components and lets you to separate the pieces of the mouse easy

here’s a photo of the screw not there

After that i tried finding places where i thought the plastic would separate and open

here’s a photo of where the plastic opened

sorry didn’t take a photo

Here’s a photo of when i opened it

Here’s a photo of the shell

Here’s a photo of the devise that controls it

There is also a small scroll wheel and a screw but that not to important


Here is what i changed it into

I also created a Game called hit the target hears a photo of the game sorry it was blurry



These few weeks my class has been working on spheros I’m in a group with Archie and me


Here’s a list of what we’ve created so far

so far we have created

Hot potato

Here’s the code

first it says on start program that activates the line of code


start of loop 10

delay 10 seconds delays the code for 10 seconds you can change the amount of time

play bubble pop sound you can change the sound but this is the sound for a player loosing

The main led turns red and it goes real fast and moves everywhere to show that you have lost

end of loop


don’t forget thee is still another line of code

On collision play chomp sound to symbolise that they haven’t lost

and also the colour green to show they haven’t lost


we have also made a square

Here’s the code


On start program / when program is started


loop 4 times / repeat 4 times if you lower the amount it will not make a full square

speed 29 / you can make it any speed we just didn’t want it to be a huge square

delay for 0.9s / again you can make it longer or shorter but this is a reasonable size

Spin 90* for 0.9s / we made it 0.9 becauseĀ  because we didn’t want to make it a very fast turn and make it go further than its supposed to

End of repeat


Speed 0 to make sure it stops after its finished



Theese few maths sessions we have been working on probability or chance but also spinners


this is something I made in one maths lesson

That what it looks like I’m going to use it for what I eat at hoe for dinner


Heres whats going on behind the wheel

Food Maths probability gues out of 10 anser
Maccas 1/32 guess 1
KFC 1/32 guess 1
rice paper rolls 9/32 guess 4
parents choose what’s for dinner 8/32 guess 3
Tacos 4/32 guess 2

Macas has 1/32 of a chance

Kfc also has 1/32 of a chance

Rice paper rolls have 9/32 of a chance

parents choose whats for dinner 8/32 times

tacos have 4/32 of a chance
