Fumes machine
Swindon Borough Council – custodians of the Magic Roundabout – have kindly agreed to my request to site a particulate sensor on traffic lights in town. It is hoped that the busy toad will provide a new data stream to add to the mountain air / classroom feeds that are already in place.
All being well, the fumes produced by passing traffic will show pm 2.5 readings that can be viewed in realtime to provide a direct comparison to those found in a pupil’s own classroom and that found within ancient woodland in Northern Ireland. Zjeremy the robot brings the sensor into classrooms – see www.flickernet.net/data or www.flickernet.net/pm25
A preliminary visit to the site has revealed open WiFi access from the nearby Co-Op which could help!
WatchBox
Coming soon – we hope – the WatchBox! This project-based-learning endeavour will offer children the opportunity to build, code and deploy, a wildlife monitoring system of their own. This will be a new way to connect with nature. For further details see here: www.flickernet.net/watchbox
Autism Support Kilkeel Event
Thank you to everyone who attended the first Autism Support Communicator event, which was held in Mourne Park on Saturday. Communicating our feelings as we explored the woods together: through the sending of images via Micro:Bit radio signals – it works!
Pi Upgrades
Led by Zjeremy, (who retains what Steve (HoD GWA) affectionately refers to as a “prototyping look”!) – a number of Raspberry Pi upgrades are now taking shape. Zjeremy needs to run Scratch 3 with a bit of vim if he is to juggle multiple HATS for interfacing with. His secondary 3b board was not up to speed, but the 4b seems happier. To celebrate, he was coded into taking images of the woodland views from the second floor of Great Western Academy.
Meanwhile low cost LCD screens set into basic plastic boxes are a quick and simple addition for classroom kit. Raspberry Pi units deliver physical computing with core electronics and more advanced sensing: it is helpful to enclose them for protection during transport. A ribbon cable allows the GPIO to be extended for easy connections.
The CarFume Detector unit is almost ready for deploying on a busy Swindon street. It will mirror the functionality of Zjeremy and the Tree Pi – providing new urban data for comparison.
Thermal woodland trail
As the cold evenings draw in, there is a type of thermal enhancement that doesn’t warm the toes much, but that does identify hidden cctv cameras in the trees! Thank you Eden for testing out your thermal imaging mobile phone functionality in our wood!
St Louis Woodland Coding fun!
Exploring the versatile Micro:Bit in Mourne Park: orienteering with a [coded] compass through the woods; searching for treasure with [coded] metal detectors then sampling the natural environment with sensors. Thank you Anthony and the team for coming along – full report here: www.flickernet.net/stlouis
Space To Learn – ready for tomorrow
Standing by to welcome St Louis Grammar School tomorrow – a specialist school in technology – and also my neighbours! Twenty Year 11 Computer Science pupils will be learning how to code Micro:Bits for outdoor learning adventures, including environmental sensing, orienteering, and even metal detecting!
Recycling Machine
Loving creating resources for team Digit<all> – with thanks to Amazon Sustainable Futures.
This is the Recycling Machine: metal detector drives a servo to sweep ferrous materials from a conveyor belt!
Reflections on a sabbatical year
From climbing trees in the woods of Northern Ireland whilst clutching Raspberry Pi units, to helping children who were on the cusp of quitting school to build adventure game-books, this year has been a real eye-opener to me.
It is a rare privilege to become free to teach what one chooses. I hadn’t dared believe that it could happen, but now Flickernet is full steam ahead – 24 years on from those early Dot Com years – with a new focus called TTH: Tech To Help. This is what I will be up to, going forward – please see the synopsis page for more information or if you would like to be involved.
Campfire Experiment
The Particulate Sensor was put to work sniffing the air above our campfire. More than just marshmallows to chew over.! Report here.
