BCS Event Report: Raspberry Pi

Two parallel Raspberry Pi activities were run by the BCS Northampton branch at the Newton Building, University of Northampton, UK 

The first activity was aimed at generating interest in the use of of VOIP on the Raspberry PI  and covered a number of topics:-

  • Outline of VOIP as a voice technology
  • Advantages of VOIP telephony for business and the consumer.
  • FreePBX on the Raspberry PI - build, configuration and usage.
  • Discussion of VOIP trunk technology, VOIP services.
  • Demo of a PI FreePBX system with two VOIP phones.

The second activity was aimed a beginners to the Raspberry Pi and was run by staff and a student from the Department of Computing and Immersive Technologies, University of Northampton. 

The central aim was, what can you do with that Raspberry Pi this half term? You brought a Raspberry Pi but never got around to using it, what could you try?  

During this session some basic example activities were shown. 
  • Basic Scratch programming activity:- Bonfire Night Game. Create graphical stars and make them act like fireworks - shot across the screen, multiply, expand changing colours and then shrink
  • Scratch control of LEDs via a Raspberry Pi making two LEDs flash all under the control of a Scratch based program.
  • Junkbot  program a robot made from a Raspberry Pi, a drinks can, pens, and a motor and get it to draw (see the video below and for more details)

The event attracted both members of the BCS and non-members (youngest two being 7 years old).

Social Analysis of Publications

The Computing staff's network of co-authors, at the University of Northampton, based on the University's  research repository NECTAR - on 12th November 2016. The data goes back to 2010.

The data was analysed using the software VOSviewer - free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.

To dig a little deeper, going to  look at the two biggest 'hubs' through their NECTAR records, so potentially going …

Computer lecturer’s research helps improve the next generation of technology

Taken from: A computing lecturer at the University of Northampton, who is researching into how the efficiency of our everyday devices, such as mobile phones, can be improved, has been awarded the best paper at two recent conferences. Dr Michael Opoku Agyeman has written several journal papers focusing on how the next generation of technology can meet the ever increasing demands from consumers. He was invited to present his work at the 19th Euromicro Conference on Digital System Design in Cyprus and the Institute of Electrical and Electronics Engineers’ 14th International Conference in Paris. Part of his research concentrates on whether several processing elements can be incorporated on a single chip, known as System-On-Chip, to improve the efficiency and speed of the computing systems that we use every day, from mobile phones to video-game consoles and even medical equipment…
