Code Club 5/3/2022 reminder
The next Club will be on Saturday 5th March 2022 @ Paignton Library. Please contact the library to book.
We will carry on with what we were doing last session, and hopefully do more with the Lego WeDo and Micro:bits.
If you are following the activities provided by code club, please use the website link below, this will hopefully avoid issues with the existing materials that are written for Scratch 2.0

Github Co-pilot discussion
Copilot is a AI tool to help developers with writing code. There will be a discussion on Thursday 3rd March and Monday 7th March to discuss various issues arising from the use of this.
More information can be found in the FSF article
This will take place on IRC Libera Chat at 19:00 UK time.

Skymaps – Celestial sky guide – March 2022
You can download a FREE celestial sky map for this month from Skymaps. These are excelent guides to the night sky. You will also find a list of what is visible, what other objects or events (e,g meteor showers) are happening. Lots going on in the night sky.

Electronic Structures of Atoms
In Chemistry is important to know how electrons are arranged in their orbitals. The guide below is a really good explanation of this.
Links
Typesetting
If you are using LaTeX to write up reports, then it may be useful to be able to confidently type set how electrons are arranged in their shells and subshells.
if we take an example for Boron from the above website, we can type set this in $\LaTeX$ using math mode:-
$1s^22s^22p_x^1$
The result is a nicely typeset electron configuration.
This is not perfect as it should display the final x as a subscript (below) the the 1 as a superscript next to this. But it should be possible to fix.
This tutorial is sort of related but may be useful for drawing diagrams.
To draw the orbital diagrams you need to use :-
\usepackage{ amssymb }
Then in the document use
\upharpoonleft and \upharpoonright
$\upharpoonleft$ and $\upharpoonright$
For this article I used detexify to figure out the \LaTeX code for the graphics.
Update : 25/2/2022
Having asked on the OU forum about this, in this thread reply I have been advised to use the mhchem package and this will type set the orbitals much better.
\usepackage[version=3]{mhchem} % you may prefer the spacing using version=4
...
$\ce{1s^2 2s^2 2p_x^1}$

Getting Hydrogen out of banana peels
Getting Hydrogen out of banana peels
This is interesting, and potentially a good way to make use of waste material. I have included a few links below, and the article link is in the main links below.
It would also be interesting to figure out if a school has such a Xenon lamp, should be possible to try and reproduce this in a school lab. I would guess the Hydrogen gas could be collected if the mass was in put in say a boillng tube, with a bung, and glass tube to a collection tube, then the Hydrogen could be collected and tested for with a lighted splint, so you would listen for the 'pop' made when the Hydrogen ignites. So on a small scale it would prove that Hydrogen can be produced.
UPDATE 25/2/2022
I have found an update to this, from the Royal Society of Chemistry article here

Building a ping pong ball shooter – part 2
Building a ping pong ball shooter
Further to the previous post, the ball shooter is now built up. I do need to solder this together, at some point. For now, it works as it is. This is the test I did at the library (more space).

Scismic : Finding your ideal industry role
The next scismic webinar is on 24th Feb
Please see here for the signup form.
Event is free, 10- 11pm UK (GMT) but your time zone will vary.
While Scismic are focussed on Biotechnology roles, these webinars usually have some takeaways for a lot of other industries, so well worth attending.

Building a ping pong ball shooter
Building a ping pong ball shooter
As part of an order from Better Equipped, I sent for a ping pong ball shooter. This consists of two rotating disks, which propel a ping pong ball forward.
So far, I have only partly built this. I need to do some soldering to complete. I also want to find a safe place to test it. This project will be demonstrated at the Paignton Library STEM group, but could be used in a school too. This would support, Science, Maths, Design & Technology and possibly other subjects.
