The Devon and Cornwall GNU/Linux User Group is for anyone who uses – or is interested in using – Free, Libre and Open Source Software. The group is made up of a wide range of people from home users to professionals and between us we have a wide range of experience and knowledge. Please feel free to join our discussion mailing list, or chat with us on IRC (chat). The Torbay meetings are now part of the Raspberry Pi jams as these are arranged by members.


Holsworthy Meeting Nov 2014

Our next meeting is due this coming Saturday 15th November at the White
Hart starting at 2 pm. As I mentioned in an earlier email this is also
the day of  Holsworthy carnival. There is usually a procession for the
young people in the afternoon, but this year this has been cancelled.

Th carnival procession itself is due to start at 7 pm so there should be
not problem for us. I have booked the meeting. Hope to see someone

Exeter Raspberry Pi jam – 1/11/2014

Today was another excellent pi jam up in Exeter,  and well attended,  the word is getting out there.


Tom Brough demonstrated the parity bit trick and also had some coloured cones to demonstrate how a bubble sort works,  you can try this take about 8 cones of different sizes and put them randomly in a line now sort them one by one so the line goes from biggest to smallest.

I spent some time, with some help working on getting scratch to talk to the pi liter,  once done (not too difficult) we spent some time then creating a program that is the same as the chaser type program written in python.  This works really well,  further enhancements allows the user to interact, chance speed as well as stop / start the routine.

I also had a chat with another user who showed me his chromebook running lubuntu.  This was also connected to the Pi with vnc,  the performance was excellent.

Ivan was also showing various projects and we had minecraft running on another pi.  In the fab lab was the usual beginner work shop where you can learn to light up leds on a bread (project) board using the raspberry Pi GPIO

So in all excellent,   Looking forward to next week as it is the Torbay Pi jam from 1 – 3 at Paignton Library,   good news is that the 3 sd cards (well micro + adapters) arrived to day so these are all ready for next week,    I may look at preparing at least one with Noobs,  as this may save time next week.

Thank you to Simon and Exeter library for hosting another pi jam and everyone who attended.

Coder Dojo South West


Coder dojo is coming to the South West,  they are looking for volunteers for Liskeard, Exeter and Torbay (Paignton).

Coderdojo is the global network of free computer programming clubs for young people.

October Pi jam

Great pi jam today

Despite the low turn out, if you didn’t make you once again missed out on some cool projects,  computer science related stuff as well as demos.

1. Knights tour,   – using a chess board how do you move 1 knight so it goes over each square once, only using the valid moves a knight can make ?

2. Sort program,  this is was a demo of the article that Tom Brough wrote yesterday  You can read the info http://www.dcglug.org.uk/network-sort-algorithm-animation/ If you would like to see the demo come to the Jam on the 8th November 2014.

3. Minecraft,  one of our younger members was using a laptop to create a 8 bit adder circuit in mine craft,  yep you can build computers inside minecraft,  again if you want to know more come next time

4. We also set up another young persons Pi , downloaded xfce so we could run that instead of the default lxde desktop environment.  It worked great once we got the pi toNovember connect to the internet then figured out how to tell X to load xfce.   Tom and Mark did a great job with this.

I brought along some cards with 1’s and 0’s,  to demonstrate how binary works,  Will make some more up for next time, I also need to bring extra power supplies along.   We made great use of the laptops donated by Dan Smith at the last jam.

Once again we did more than JUST raspberry pi.  We are focussing on computer science and coding too.

Hopefully, next month we can get a full demo of the minecraft 8 bit adder,  as it’s really interesting (and kinda complex) but it should be possible to also use my binary cards to explain what is happening in a different way.  Want to know how 1 + 1 = 11  then come along next time.

Usual goodies of free stickers are still available along with gummy bears,
