So I was lucky enough to be asked to come along to a second Picademy event, not something many people get to do unless they are facilitating the event…
It started a while back when James Robinson from Raspberry Pi put a production company working for Google in touch with me. They were keen to get some interviews and video footage to demonstrate the impact that their support for the Raspberry Pi Picademy training programme had generated. James suggested they speak to me and I was more than happy to oblige. So after many email exchanges and phone calls between myself and the production company a plan was formed to get the video footage Google wanted to tell the story!

Over the past couple of months I have been lucky enough to be invited by the Raspberry Pi Foundation to attend two of their events in London.
The first of these events took place on September 8th, on the terrace of the Houses of Parliament, to celebrate the sale of 10 million Raspberry Pi computers. The event was attending by a wide cross-section of the Raspberry Pi community and afforded me the opportunity to meet with many people who I had, until then, only had had the pleasure of working with on-line. This opportunity also introduced me to a wide range of other partners and people involved in the development and engineering of Britain’s best-selling computer to date.
The second event I was invited to attend was held on the 5th October; a reception at St James’s Palace hosted by the Raspberry Pi Foundation’s patron, the Duke of York. This event was a celebration of, and a “thank you” to, the many different people and organisations who support and make up the Raspberry Pi community. Again, this event gave me the opportunity to meet up again with many familiar faces and get to know a few new faces, too!

This weekend I was lucky enough to be involved with hosting the second Raspberry Pi Jam event that Hull has seen. Through Twitter, Claire Garside and myself got talking and a tweet of my Raspberry Pi robot I was building one weekend, led to a discussion about re-igniting the Raspberry Jam events in Hull.
Thanks must go to Claire and the Leeds Raspberry Jam team for the loan of all the equipment which allowed our event to go ahead. Thanks also must go to Malet Lambert and Stephen Logan for allowing us to use their space.
The event kicked off with an introduction to the Raspberry Pi and allowed people to get hands on setting up their Pi and getting everything running. They then had a chance to hack a Scratch game and try to improve it.

So as I went into day 2 of #Picademy I had decided upon a “motion activated camera which tweets the photo taken along with a random poem, giving you a LED countdown indicator” for my project.
Some of this I had previously coded (the random poem part) which you can see running in this Trinket app below:
My thoughts were that I could make use of this to create the text of my tweet adding the #Picademy hashtag to the end too.

So after day one of #Picademy my evening was spent thinking about, and reading about what I could do for my project on day 2.
My initial thoughts was to use a USB microphone to get an audio feed into a Raspberry Pi to then try and use Python to “listen” to the microphone and react to different audio levels coming in; a kind of graduated analogue switch if you like… So between #Picademy finishing and meeting up for the evening meal I spent my time walking (quickly!) around Manchester trying to find a shop selling basic USB microphones; to no avail!
So over the evening meal I was discussing this idea more with Les and we thought it maybe possible to use the Jack Audio Server to flip the Pi’s inbuilt headphone jack into a microphone jack. This is possible on Ubuntu, as a quick search on our phones verified; so I thought we were on to a winner here. However after a little playing around with my Pi back at the hotel, it turns out that the HDA-Jack-Retask application just does not work with the Raspberry Pi soundcard 🙁
This left me back at square one… What do to on day 2?
So I wake with this thought… “A motion activated camera which tweets the photo taken along with a random poem, giving you a LED countdown indicator” – Should be easy!
Watch this space for progress!
This February I was one of the lucky few to be accepted on the Picademy event at Google’s Digital Garage in Manchester. More details about the event can be found here: https://www.raspberrypi.org/picademy/google/manchester/
This post is a summary of my thoughts after day one – more as a memorandum for me than anything else. Apologies if I have forgotten any of the sessions or put them in the wrong order; to coin a phrase used in the training, I reached “cognitive overload” fairly quickly!

This week my Year 8 class asked if they could do something festive with me for their last lesson before we break up next week. Now I am not a believer in stopping work just because it is the last week of term, but I thought I could probably give them a Computer Science lesson and easily add a Christmas theme to get the best of both worlds. I gave them the choice of either using Python Turtle art to create festive pictures, or use Sonic Pi to “code” some Christmas music.
The class went for Sonic Pi; so I thought I would share my lesson plan here.

We are just about to begin teaching our Python and Minecraft unit at school so I began testing everything out on our latest Raspberry Pi image to make sure we were ready for the lessons and adjust any of the lesson plans if necessary.
Our latest Raspberry Pi image runs Jessie. Now one of the improvements Jessie brings us is that the Print Screen button on your keyboard has been set up to run Scrot in the background to save a png screen shot into your home directory. You can read more about it here.
Now that is great as for quite some time taking a screen shot on your Raspberry Pi involved installing Scrot and then running it from the terminal; not the most user-friendly way to get students to take screen shots!

I have seen many posts on both Twitter and CAS about teachers having issues getting their class Raspberry Pis to update and install software through their school firewalls, so I thought I would share the simple solution that I have implemented at my school.
It actually leverages something that I put in place for our Ubuntu Linux servers, but works just as well for Raspberry Pi devices too.

We have just purchased a set of Raspberry Pi 2 boards to upgrade our Raspberry Pi B+ / HDMIPI set-up which we have been using for Computer Science this year. I will not go into the reasons why or the specifications of the Raspberry Pi 2; but needless to say the performance increase seen will make teaching with these devices much easier!
So we received our new Pi 2 boards and got straight into removing the old B+ boards from our HDMIPI set-up and installing the new Pi 2 boards. Pretty soon I ran into an issue though; having replaced the Pi board and using one of our SD Cards with our current image installed on it, the system would not boot; it just sat there at the rainbow boot screen. It turns out that the Pi 2 has an updated ARM processor and therefore needs the latest updates installing for the Pi to boot. Now I could have just downloaded the latest Rasbian image and been up and running, but we have quite a few customisations to our image which I wanted to keep
