Raspberry Pi 5

 

usecases 1 week in:

• Marking work on Class notebook on office 365
• whilst listening to you tube 
• editing a blog 
• organizing a raspberry jam 
• responding to school email through office 365.

In summary 1 week in multi tasking on basic school and teacher based tasks are now completed on my pi 5 rather than my school laptop. There is inevitably things I have to do on m school laptop like accessing SIM's and other things but this Pi 5 is very much going to reduce my dependence and need to bring my Laptop  home. In summary so far Pi 5 and not even over clocked is a game changer....

Over!

Craig and Dave videos student recall questions....

Hi all, 

I'm attempting to train my year 12 GCE CS students into watching the Craig and Dave videos before they attend lessons to free up more time for coding and so they have some concept before attending the lesson. Craig and Dave promote this flipped learning approach and Alan O D has been talking about it for many years. As part of this process I have been trawling through videos of recent topics and posting questions based the videos as evidence that they have actually done this and to serve as useful notes these are the few that I have done so far are green........

(a) Arrays (of up to 3 dimensions), records, lists, tuples. 

(b) The following structures to store data: linked-list, graph (directed and undirected), stack, queue, tree, binary search tree, hash table. 

(c) How to create, traverse, add data to and remove data from the data structures mentioned above. (NB this can be either using arrays and procedural programming or an object-oriented approach).

Rainbow Road

   

Rainbow Road

In order to get the below code you will need to follow these blogs in order to get started:

Setting up the server link

My first code link

In this code you will use the following skills:

+Import code from libraries

+Create a connection to the Minecraft server(local on this pc only)

+Create a procedure to draw/drop a rainbow road beneath your feet every time that you move

Coding key skills

Selection	Iteration	Sequence	Data Structures(Lists)
Variables	Data Structures(2D arrays)	Input	Output
Logical Operators	Mathematical operators	String manipulation	Functions
Procedures	File handling

Instructions:

 Follow the steps below and you will get there pretty quickly:

1.Open Idle

2.Click on “File” > “New File”

3.Type out the following code

In the Adventures with Minecraft folder click on “Start Server”

5.At this point press enter and the following should happen….

7. Next press enter...then this should happen.....

 9. Next on Minecraft select “Multiplayer”.

9.Then type in "local host"

10.Type in local host and hit the “join server” button.

11. Press “Esc” on the keyboard to allow yourself to quickly pop back to IDLE so you can save and run your code.

12. In IDLE “File” >> “Save As” >> Call it “Rainbow road.py”

13. For it to work you will need to save it in a specific folder which is:

“AIMStarterKitPC\AdventuresInMinecraft-PC\MyAdventures”

Like I have here:

14. Still in IDLE select “Run” >> “Run Module”

15. Head back to Minecraft and you should see your code in action:

16. To kill the code / stop I from working you will need to press “Esc” >>> find this window in IDLE then close it down. See below:

Forcefield

  

Forcefield

Before we go any further this code was originally created by Elton Lane(@piinthesky2015) a few years back as part of a Minecraft coding resource pack that I curated called the "hackpack" see link. He has kindly said that he doesn't mind me reusing this code for this Java coding retake on Minecraft Python coding. This code will allow you to bore big chunks out of the landscape. See the demo video at the bottom for a demo of it in use.   

In order to get the below code to work you will need to follow these blogs in order to get started:

Setting up the server link

My first code link

In this code you will use the following skills:

+Import code from libraries

+Create a connection to the Minecraft server(local on this pc only)

+Create a procedure to draw a air "forcefield"

+ Using parameters 

+Conditional statements

Like I have here you can see three example programs:

14. Still in IDLE select “Run” >> “Run Module”

15. Head back to Minecraft and you should see your code in action:
