RASPBERRY PI IV – October London Raspberry Jam

[Fig.1] Solving problems that new users have at the hack event.

Yesterday was the October London Raspberry Pi Jam at the Mozilla Space in London. This particular event was more geared up to be a hack evening. There were around 25 attendees, thus it was a smaller event than previous occasions; we discovered this was due to the fact that we did not email the eventbrite mailing list, so only those who are signed up on meetup and twitter users would have heard about it. This issue will be rectified for November.

There were several interesting projects and demonstrations present. The first project I saw was someone who was setting up a remote camera system. The Raspberry Pi was sending a webcam stream over Wi-Fi, and he was working on getting it set up to send it over GSM. In addition there was an interface to Arduino to control a Servo motor to allow the camera to pivot. He had a breadboard thermal sensor interface set up also, and would like to add thermal sensors.

We had a student present that had just received his 512MB RPi and wanted help setting it up. Initial attempts to get a port pass-through Wi-Fi connection to work via Ethernet were unsuccessful but rest assured a small group of individuals got it up and running. Something he confessed he would have struggled to do on his own. Very much in the spirit of the evening, help was on hand from all sides.

Peter (@555) had returned with his Lego NXT robot, now with on board RPi. He was having problems with the USB identification of the NXT computer on the RPi. He eventually wants to get it working completely wirelessly to allow live updating of the program from a remote terminal.

There was a lovely chap who had downloaded virtually all the GUI (Graphical User Interface) available on the Debian repository; this was a trip down memory lane for those present as TWM, CDE and other window managers were shown off, all working efficiently. The benefit of using a GUI designed in 1993 is that it is incredibly light weight unlike modern operating system GUI’s such as windows explorer. In fact the only reason CDE is in fact open source is that the man doing the demonstration had been working for seven years in his spare time to get the proprietors to release the source code. For the brave the Alpha Build for Linux is available [HERE].

Keith Dunlop was busy working on the big screen using an RPi running RISCOS. This operating system I have mentioned before was designed for ARM from the outset and has some great mouse control features as well as being incredibly lightweight. The current version of the OS is 2.4MB including vector graphics program, a text editor and a bitmap editor. Its official release is on Saturday at the RISCOS London Show. If you are around on Saturday it is worth checking out. Information on the event can be found [HERE].

One teacher had been awarded £2 000 to get an RPi project into their curriculum, so a big congratulations to them; they were surrounded all night by people discussing ideas on how she should use it. This is exactly what they wanted from the evening and I hope it was as helpful as they had hoped.

Next time we will endeavour to get a couple of speakers in and we will certainly do more to ensure all those who would be interested in attending will hear about it. As always if you enjoyed reading, please follow in the sidebar or on twitter (@scientificmoust). Thank you again to the Mozilla Space for hosting. The meetup group for the London Jam events can be found [HERE].
