Minetest

I have now set up a Minetest server on a Raspberry Pi. This works and I am able to ssh in to the Pi and start remotely.

I have also set up a 3.5” Pi screen, set the pi to auto login and display the IP address(s) of the Pi. I followed some of the instructions at [2],[3] to set up the screen but didn't need the sections for setting up the gui.

The next step is to set up a router so try and provide an internal network at the library for playing minetest. I followed so

1. Minetest
2. 3.5 Inch RPi Display Touch – XPT2046 (480x320) Guide – Raspberry Pi Forums part 1
3. pi 3 – What have you done to make generic TFT touchscreen display work? – Raspberry Pi Stack Exchange part 2

Should be able to bring some of this to the STEM Group on Saturday and probably need help setting up the router to provide a simple LAN.

STEM Group 24th February 2024 Write Up

Today we had an update from Helen with her Advanced Lego car, this is going really well and can find objects and now turns to avoid them. It can also display information on orientation on a small LCD.

After giving the hot glue gun a quick clean and repair. This photo is posed as the glue gun is still plugged in.

We carried on with building the cars, we have been trying to build for the last few sessions. The main issue is lack of suitable resources and having to use bottle tops for wheels, kebab sticks for axels and then trying to fit it all together, when we also have either faulty or unsuitable switches, some don't work properly,, and along with motors have been soldered up too many times.

I also checked on my Copper Sulfate crystals I started last week, the liquid has now evaporated leaving some crystals in the dish, not ideal, but I need a much better way to do all this.

STEM Group 24th February 2024

The next Stem group event will take place on :

Date: Saturday Feb 24th 2024 Time: 10:30am to 15:00 Location: Paignton Library and Information Centre Room: 12

Please remember you need to bring your OWN resources such as wire, solder, glue sticks, components etc.

We can carry on with :-

• Robot car projects
• Have a look at the results of dropping a gummy sweet in to Vinegar
• Hopefully have a look at some Copper Sulfate crystals, I set this up on 17/2/2024
• Coding activities can still take place in the IT learning centre
• What ever else people bring along to the event.

STEM Group 10th February 2024 Write up

So today there were a total of 4 people who attended, Helen demonstrated various robots made from Lego. We also carried on making the poor man version with scraps of card, scraps of wire, motors and milk bottle tops. This method is NOT working, but it is ALL we have access to.

Cardboard Car 1

Cardboard Car 2

Lego car 1

This robot is mega advanced, has the ability to range find so it knows where it is in relation to obstacles, has a build in IP camera, and can move, by next meeting more features will be added. It also uses an IR remote control.

Something to aim for when you start building projects.

Lego car 2

This robot car just moves very fast across the room.

We also tried to do more chemistry but ended up just adding vinegar to bicarbonate of Soda.

I will try and get the Lego We do sorted out for next time, as I need time to pick up the Tablets, then will need help to get them to connect to the Lego via Bluetooth, which I struggle with.

Next Stem group meeting is on Saturday 24th Feb at Paignton Library, room 12, between 10:30 and 15:00.

We will probably carry on with the robot car we have been working on and see what people bring with them to showcase.

STEM Group intro video

I made a quick intro video to try and explain what we are about a little more. Hopefully the sound is OK, it may need turning up.

STEM Group 9th September 2023 – Details

As previously mentioned, we will be in room 12, as there is more room for STEM activities. This gives us more space, access to resources as well as sinks, work surfaces and other items.

I have planned some practical science activities which will be around using Bicarbonate of Soda and Vinegar. To keep things simple I will just set up TWO experiments.

This will be:

• Using this mixture in a zip lock bag to demonstrate air pressure
• Make a cool pack. This demonstrates Endothermic reactions
• Planning and risk assessment can be found here

In addition to this we can still do

• Computing
  • As the programmable caterpillars proved popular, I have requested if we can have them again for September

And take a look at what people bring with them.

More info

Please get in touch for further details or to suggest ideas. Please check back here for updates to what is planned or see my main blog for more frequent updates.

STEM Group 9th September 2023

From September the STEM group will start to focus more on the Science, Technology, Engineering and maths, rather than computing which can be done at Code Club,

As a result, we will be in Room 12, so that we have access to the Science and other equipment stored there. The IT learning centre will be CLOSED.

I have a few activity ideas in mind based on what happened in August.

Please get in touch for further details. I will also post a update to what is planned shortly.
