Thanks to my esteemed colleague Jean-Marc Drouet in Canada, I have recently discovered a new world of statistics called Boostrapping to resample data and produce confidence intervals for a resampled distribution of data. I’ve found a nice free online tool… Continue Reading
Calculating drag co-efficient, Cd of a sphere Here is a great tutorial to calculate the drag co-efficient for various Reynold’s numbers. The model here is an external steady-state CFD model. It’s external because the fluid flows around the outside of… Continue Reading
Embedded programming options on the Microbit Embedded programming a term used for programming (writing code for) microcontrollers. It is also known as embedded software development or embedded systems programming. Essentially, embedded programming is useful in the design of software for… Continue Reading
Autodesk Eagle Autodesk Eagle is a PCB (printed circuit board) design software that is free to use for relatively simple circuits. Designing simple through-hole electrical circuits in Eagle The library system is very confusing, but here is how to find… Continue Reading
OLED screen with Micro:bit using Makecode and Python Here is a nice guide describing the process of setting up the 0.96″ OLED screens to work on the Micro:bit. This uses both Javascript (makecode – for simple text) and MicroPython (this… Continue Reading
Programming the Microbit in the Arduino IDE It is possible to use the Arduino IDE to programme the microbit. Here I’ve done this using 2 examples: to use generic example programmes to turn on LEDs, measure acceleration, temperature use bluetooth… Continue Reading
Measuring acceleration on a water rocket with the Microbit The Microbit can be used to measure the rocket acceleration and can send data using the the radio transmission to send it to another microbit connected to a PC. It really… Continue Reading
Using the 12864 I2C OLED screen on Microbit Here is a nice project done in the Makecode BLOCK environment where the Micro:bit will measure give the min and max temperatures that it is exposed to over a period. It is… Continue Reading
Introduction This guide outlines the induction exercise for using the Imes-Icore M40 3-axis router which is situated in the E28 workshop in heavy engineering, Cockcroft Building. Note that the induction only includes cutting .dxf files (i.e. 2.5 axis cutting). In… Continue Reading
This is a test image to use as my featured . I found a site that says a generic size for images to use on WordPress (and hence Edublogs) is 1200 x 628 pixels. This has an aspect ratio of… Continue Reading
