Minecraft, jam and history in the making

Taken from:

History was made on Saturday as the University of Northampton hosted Northamptonshire’s first-ever Raspberry Jam. Raspberry Jams see those with an interest in the affordable – and tiny –Raspberry Pi computer get together to share knowledge, learn new things and meet other enthusiasts. More than 30 people of all ages attended the county’s inaugural Jam at Avenue Campus, which was organised by the University’s Associate Professor in Computing and Immersive Technologies, Dr Scott Turner. He said: “The Jam was a real success, with a wide mixture of people including fairly notable experts; those who have a Pi, but aren’t quite sure what to do with it and complete novices. “It was great to see people who had some sort of Pi-related query have their questions answered, and others showing off what they have managed to get their Pi to do. “It really helped to inspire the novices to get more involved in the R…

Dancing bot on a Microbit

In a earlier post on using micro:bit (Playing with microbit emulator-dancing bot)  a simple dancing robot image (using the 5x 5 grid was created). 
A dancing bot - 3x3 box for the body, with two legs. 

Thanks to a loan of a Micro:Bit from Lancaster University I can experiment with an actual micro:bit ()

Experiment  1 - Using the buttons

So the functions for the idea were:

Button A - Move to the left and then back to the starting position;Button B - Move to the right and then back to the starting position;Buttons A+B - Jump up and then back to the starting position;Shake - 'Crouches' and then back to the starting position

On the Microbit

Experiment 2- To add left and right tilting to it.
So if the micro:bit is tilted to the right the 'bot'  moves to the right, and the same for the left.

The tilting operation here is essentially - when the x on the accelerometer is less than zero move the 'bot' to the left and when it greater than zero go to the…

Pimoroni Flotilla first play with Python.

The Mega Treasure Chest Flotilla set from Pimoroni, was kickstarter project that got a lot of people interested. A nice package - a hub for a collection of devices such as light sensors, barometer, temperature, switches, motors and many more; all linked to a Raspberry Pi. The kit is shown in the image to the left.

A Python API exist for this system. Instructions on how to set up the Flotilla to work with Python can be found at .
I wanted to play with switching the Rainbow (A set of RGB LEDs) outputs to Red, Blue and Green by pressing either 2,3, or 4 on the Touch Sensor as in the images.

Using the mini-kit example from as the basis, produced a simple system that uses the Touch module and its buttons 2,3 and 4 to change the Rainbow; the code is shown below and ran on a Raspberry Pi 3 using Python 3.

import colorsys import flotilla import time
client= flotilla.Client(     requires={         '…

Experiences with Raspberry Pi Touch Screen

Well for once I am not going to be talking about robots, but my experience in setting up a Raspberry Pi touch screen - this is not a how to guide, a couple links to those are included in the post, but my experience of setting one up. 

So the I bought the Raspberry Pi Touch Screen from Pimoroni and along with the stand/frame for it.

Setting up the LCD frame was simple with the instructions provided and the link at the end of the instructions provide some further help on setting up the screen

A tutorial from The PiHut ( was very useful on how to connect the screen to the Pi. The blue side  on the white ribbon cable (provided with the screen) used in connecting the two together needs to blue side down towards the LCD (as explained in PiHut tutorial) and facing away from the Pi when connecting to it…
