Raspberry Pi RC Lego car

In the next iteration of the Raspberry Pi based controlling of Lego motors I purchased another basic motor previously used with the Ferris Wheel, the aim was to create a simple RC Lego car. The remote control is the same idea as in the RaspiExpress using GuiZero and accessing that over wifi on my Iphone using Real VNC.

Here is a photo of the latest hacked together vehicle:

Here is a video of it working.... Link

Not a blog at all at this point simply a dump of the code. Write up to follow for now the code ..... https://t.co/60lTJxyFyD pic.twitter.com/ot78uELutg

3d printed light up Lego Christmas Tree

Kari Lawler has helped out at several jams over the last 18 months and has kindly made some 3d printed christmas trees that slot together and sit nicely on a Lego brick. Here is the relevant info if this something that interests you:

Here is the 3D stl file : link
Here is a video of it working: link
Here is the code : link

To control the light you will need:

• 1 x neo pixel 
• 1 x Micro:bit
• 3 x crocodile clips
• Power for the Micro:bit

Here are basic images of how it was put together:

Blocks controlling blocks

This recycles the code from the RaspiExpress and replaces the GUI buttons with whacking different blocks in Minecraft. This still uses a Raspberry Pi and a Lego motor. The same Edu Kit 3 motor controller/ hat is used. Please see a video below of how the initial test worked.

Here is a link to the code: link

25 Minecraft hacks of Christmas '18

Over the next 25 days I shall be recycling existing blogs and maybe a few new ones to look at 25 different coding experiments with Minecraft and Python.

Day 1: Modding interface with GUIZero. This experiment pulls together several previous coding experiments and cements them all into one GUI which can trigger a range of different array of block based events.

TUI Calculator/ binary to denary conversion

This is code covers:

• Casting 
• Functions 
• Tui's
• Basic input
• Procedures
• String element checking
• Basic mathematical operators
• Simple validation on binary section

It allows the user to chose from a text based menu and either:

• add, subtract, divide or multiply two numbers that the user inputs
• enter an 8 bit binary number and convert it denary

Here is the code:

Lists and TUI's

Here is a program I used with year 9 to introduce list basic list functions and TUI's.
It contains:

• selection
• procedures
• procedure calls
• casting 
• pop
• remove 
• lists 
• append

It is a very simple simulation of a "game server" allows the user to add gamer tags, remove and pop off the end of the list. 

Here is the code : link

Micro:bit Express 2.0 'adjustable speed'

This is an incremental improvement to the original Micro:bit Express which went via remote control fwd and back and stop. The next project the Micro:bit controlled Ferris Wheel allowed you to adjust the speed within a small range. This project applies the same logic to the train with a greater range of speed.

You will need all the same kit as in the original blog here is the key info:

• A video of the updated train in action link
• Code for the updated remote link
•  Code for the updated motor controller link 

Enjoy :)
