The National Teaching Repository (NTR) has just won a prestigious national award for teaching and learning — the Collaborative Award for Teaching Excellence 2026 . Good timing, then, to bring together two things I've been enjoying lately: being part of the NTR board, and playing with AI to solve problems. I wanted to see what happened if I pointed some vibe-coding and some AI-assisted analysis at the repository itself. Could I surface patterns in the NTR that aren't obvious just from browsing it — the invisible web of who has worked with whom, and what the collective body of work is actually about ? Two small activities, one feeding into the other. Activity 1: Mapping co-author connections The first idea was simple: go through the NTR's FigShare listing and map the links between authors, to see the inter-connectedness that has organically built up over the years. The prompt I used was: I would like to go through the https://figshare.edgehill.ac.uk/The_National_T...

The Earth is restless. In any given month, earthquakes rattle the planet — most too small to feel, but all carefully recorded by sensors around the globe. What if you could pull all of that data into Python and put it on a map in minutes? That is exactly what this project does. There is something compelling about real, live data. It is one thing to practise Python with made-up lists and fictional datasets; it is another to write a handful of lines of code and get back information about actual geological events happening right now. This project is a great entry point into the world of APIs — the digital doorways that let your programs reach out to the internet and bring back structured information. We are going to pull a month's worth of earthquake data from the US Geological Survey (USGS) , load it into a Python DataFrame, and then plot it on an interactive map. No specialist hardware required — just Python and curiosity. 💡 This project was inspired by the "Fetching Cu...

The last of the posts on the Hug avoider and the 4Tronix's Eggbit 4Tronix's Eggbit (in fact I bought three of them  https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/eggbit-three-pack-special   :-) recently) is a cute add-on for the microbit.

In two recent posts, Makecode was used with the Enviro:bit from Pimoroni to try out a few ideas ( https://robotsandphysicalcomputing.blogspot.com/2021/06/pimoroni-envirobit.html  and   https://robotsandphysicalcomputing.blogspot.com/2021/06/pimoroni-envirobit-light-and-led.html ). In this post Pyton using the Mu editor was used to try out the Enviro:bit. As in the makeCode version, Pimoroni has provided both a python library (via Github) but also within the Readme.md useful installation instructions. There is at the time of writing a possible typo; to get the BME280 sensor (temperature, pressure, humidity sensor) to work; you need to add parenthesis in the line  bme = bme280.bme280() After that, it works fine and includes potential altitude measurement which I don't think is in the Makecode version (though I could be wrong); I need to play with it a bit more. To experiment the code below was used test reading temperature (in Centigrade), humidity (%), and altitude (f...

Code Bug has been around for a while, and it is incredibly cute, When it first came, it was a very interesting piece of kit - and it is still is and fun to play with. It spec means it is still a very useful piece of kit. 5x5 Red LED display 2 buttons 6 touch sensitive I/O pads (4 input/output, power and ground) Micro USB socket CR2032 battery holder Expansion port for I2C, SPI and UART Blockly-based online programming interface CodeBug emulator for checking code before downloading In 2020 Code Bug launched and successfully funded a Kickstarter campaign ( https://www.kickstarter.com/projects/codebug/codebug-connect-cute-colourful-and-programmable-iot-wearable ) for a new version the Code Bug - CodeBug Connect with a serious upgrade.(and the name Connect is highly appropriate with USB tethering and Wifi capability in this version.
