Paignton Library STEM Group – August 2022 Writeup
The August STEM group meeting took place on Saturday 13/8/2022. It was a quiet meeting but fairly productive.
I partly set up a monitor / keyboard and mouse as I was expecting 2 attendees to come along for help with a Raspberry Pi. They didn't make it so we just carried on with the other planned activities.
We watched the August Space Telescope Science Institute public lecture ( recording ) and had an interesting discussion around this, which also led to a discussion on photography and infra red and UV filtering. Harding also offered a talk on Space and time, which we will discuss further and agree for a later date.
Prior to the meeting starting, and with help from Loic at the library, we set up a tablet with the Lego WeDo 2.0 and got this working. So this is another activity for both Code Club and a future STEM Group meeting.
The next two Code Club will take place on the 20th August and 3rd September, while the next STEM group meeting will be on 10th September. So hopefully more of the same.

Paignton Library STEM Group – August 2022
The August STEM group meeting will take place on Saturday 13/8/2022. As with previous events, this will be a mix of Science, Technology, and Engineering subjects along with discussions and a look at projects brought along to the event.
We will be watching the August Space Telescope Science Institute public lecture ( recording )
Note : I have now fixed the issue with low volume, so we can now turn the sound up to level where people can hear any audio clearly.
Description
Speaker: Alexandra Lockwood (Space Telescope Science Institute)
The Webb Space Telescope has recently showcased its spectacular first images and is now ready to do incredible science! It has been a long road to get here, including meticulous planning, exacting execution, and an amazing amount of teamwork! Join Dr. Alex Lockwood as she talks about the journey from launch to commissioning, explores details of the first images and spectra, and helps us understand the awesome scientific potential of NASA's newest great observatory.
Recorded live on Tuesday, August 2, 2022.
Preceding this I have found a short video to explain emission and absorption spectra,
I have linked some courses on FreeCodeCamp, that are partially related to data analysis and use of Python in Science.
Schedule (talk / video stream)
- Emission and Absorption Line Spectra – A Level Physics
- James Webb – First image & Spectra – STSCI Lecture
- STSCI
- JWST
- I have downloaded and printed the technical specification for the Nancy Grace Roman Telescope and will make this available too.
- Science forums question on spectra and molecules
The plan is to watch video, then have a discussion around this.
Schedule (projects stream)
As we are a bring you own projects group, then attendees can bring what they are working on, or perhaps carry on with what they are doing at Code Club for example.

STEM Science Session at Paignton Library
Sphere science will be running a family science session on Tuesday 23rd August at Paignton Library.
They are looking for some teenage volunteers to help run the session. Training provided in the morning, then after lunch present some activities to families.
Please see below for details

Code Club & STEM Group updates 4
Identify different video out connectors. I am making this post, as I may need to ask people what type of video connectors they have on their hardware, this will help them, help me. I can then turn up at a school or other venue with the correct cables.
A few pictures below, from OpenClipArt
VGA Connector
HDMI Connector, this should give a rough idea of the size, shape

Code Club & STEM Group updates 3
Pi-Brella
The Pi-brella is a small add on board for the original Raspberry Pi, but still functions on newer models. This had features, such as a buzzer, i/o sockets, a switch and LEDs.

Code Club & STEM Group updates 2
Working on a few resources to support code club, if there are doubts about my ability to put effort in to something then these are clearly misguided.
I am looking for employment to support and help with STEM. At code club & STEM Group, I think there is scope to help with
- Physical computing
- Electronics
- General coding (Scratch, Python)
- Networking
- BASH Command line
- BASH Scripting
- Data Detox workshops
- Study skills
Along with a lot more,
A few photos below
Raspberry Pi, set up with a Breadboard and wires. I just need to re-flash the SDcard.
LED Bargraph (this can be connected to a PI using Female to Female leads, however using Female to Male leads, it can be connected to an Arduino.)
LED Traffic Lights (this can be connected to a PI using Female to Female leads, however using Female to Male leads, it can be connected to an Arduino.)
The GPIO header allows connection of a Pi to a header on a breadboard for prototyping, the other end (under the board) plugs in to the Pi.
We will hopefully carry on at the next STEM Group meeting.

Transistor Amplifier
I have finished building a transistor Amplifier. This is in preparation for the next STEM group meeting, on April 9th.
As this contains a voltage divider, I have also built a few more resistor boards, with the view of presenting an activity around this.

Resistor boards
This is a repost and update for a previous post. I am posting this here too.
As the next Paignton Library Stem Group meeting is
Date : Saturday 9th April 2022 Times : 11am –> 15:00
In preparation for the next event, I have been working on creating some electronics resources to demonstrate at the event.
These are quite simple to make, solder on headers and which ever component is needed for that particular board
Various resistors 270ohm 330ohm 1k ohm 10k ohm
As of 23/3/2022 I have made up the following:-
- 20K
- 1 M
- 2,2K
- 15K
- 80k
Which I hope to use for demonstrating voltage dividers.
A few pictures of some previous boards, that I have built up.
Power supply, we need to get power from a battery to the circuit.
Reed switch (not soldered), 1uF capacitors (soldered) and a switch block, not soldered as I want to figure out which switch block to use (I have a few)
I have added a 3 way header as this allows for:
- Components to be attached together
- Branches in circuits
- Connection of meters, scopes and other equipment
It should be possible to build a circuit that, internally will flash, for example an LED then use a scope to examine the frequencies at different points in the circuit.
I plan to solder up other component boards. Hopefully I will have something to demonstrate, but other visitors should be able to have a go.

Moonhack 2022
Moonhack is a free international event bringing kids from across the world together for a week of coding! Suitable for kids ages 8-15, it's a free, easy and hands-on way to get coding, no matter where you are. Over the past 6 years, more than 150,000 kids have coded as part of Moonhack. founding partners
Details for 2022 are still due to be announced, however there is no reason why you can't look at lasts years projects and think about forming a team for this years Contest.
In fact why not use the Paignton Library STEM Group meetings as an opportunity to get a team together, meet up and see what help / support is needed, then look at registering your team.
