A step back in time to the 1980's with a Raspberry Pi...no flux capacitor required.

Over the weekend I took home one of the Raspberry Pi prototypes.  From the moment I took the first byte of the Pi, memories came flooding back...

So before I talk about how I got on with the Raspberry Pi, I thought i'd reminisce a little..... In 1981 our school got a Sinclair ZX81. I was 9 years old and pretty clueless about technology, but the moment I started playing with it I was fascinated. In particular I remember vividly that rubber keyboard that, if you pressed too hard on a key, got stuck in and caused the characters to whiz along the screen until you could prise it free! By today’s standards, you couldn’t do much with it - a bit of basic programming and a few clunky games - but it kick started the home computing revolution, closely followed by the BBC Micro.

A couple of years later, thanks to movies like Wargames, and a whole lot of whining to my parents, Christmas 1983 finally delivered the first computer of my very own. A Commodore 64, it made my Atari 2600 games console look like an antique piece of furniture.

Pimp my mobile phone mast

Like any respectable Geek, I've done my fair share of modifying stuff to make it "work better", or in some cases...accidently set fire to it!.  But in the case of these mobile phone masts, it's purely cosmetic.

If we were to take a before an after picture, I guess it would be bit like those makeover TV shows where they take a plain looking man or woman, give them a new haircut, new clothes and some strategic waxing, and hey presto... they look like a supermodel... well sometimes anyway... In the case of these telecoms masts, it's about blending in with the natural surroundings, and they've done a good job! The one in the picture is on the M4 motorway near Newbury in the UK, and belongs to Vodafone, whose HQ is down the road.  I've driven past this mast many times, but never noticed it before until I was in the car with a friend who pointed it out to me.

This just shows that technology and nature can blend together, and until we can get the trees to form a communications infrastructure, just as they do on the moon of Pandora in the movie Avatar, then we're have to make do with a make over regime.   I just wish they could do the same for Electricity Pylons, although my nephew thinks they look like Read more

Raspberry Pi and Custard for Schools

Ok, so this isn't a post about food! but it is a story about a recipe destined for success.

Raspberry Pi is a low cost credit card sized ARM/GNU based single board computer that runs on a Linux Platform and plugs into your TV, just add a mouse and keyboard and a little imagination.  It will be available to buy soon at around £22 for the fully loaded version.  It's the brain child of Eben Upton, who's work as an admissions officer at Cambridge university made him realise that "kids today", were happy to use and play with technology, but not interested in programming or designing it , hence the visible decline year on year of students wishing to study technology based subjects, such as electronics.

The Open Source Energy Monitor workshop at OSHUG Camp 2011

OSHUG           OSHCAMP October 2011

                  Openenergymonitor



In October 2011, DesignSpark sponsored OSHCAMP.  One of the workshops was about an Arduino based Energy Monitor.



As most of us know, Arduino is a brilliant platform for building projects.  Being part of the Open Source community means that we can share our ideas and help each other develop projects. The Openenergymonitor is a brilliant example of how we can get access to applications and build them for ourselves. 

Today, society is focused on saving energy, and how we can be more efficient with the energy we do use. With rocketing gas and electricity prices, we are all looking to reduce our bills. The openenergymonitor can help you understand the energy consumption of your home.  You can then make changes and impro… Read more

Happy Birthday Robert Noyce

Robert Noyce and his collegue Jack Kilby were credited as the inventors of the modern Integrated Circuit (IC), that is the backbone of todays electronics design.  Noyce, once known as the Mayor of Silicon Valley, would have been 84 years old today, but became the Mayor of Silicon Heaven, when he died in 1990.

A snap shot of Robert's journey to inventing one of the most revolutionary pieces of technology in our time, starts at the ultimate Geeks Mecca.... MIT, Massachusetts Institute of Technology.  After graduating MIT in 1953, Robert joined the Shockley Semiconductor Laboratory in 1956, but the following year, he and 7 of his colleagues broke away to set up Fairchild Semiconductor, and in 1958, the Modern Integrated Circuit was born.

Since then Semiconductor Technology has evolved at an incredible rate.  However, this is where Moores Law comes into the equation. Moores law is basically the theory that there is a point where Semiconducter technology will reach it’s limit with the number of transistors that can be placed in the circuit.  It’s currently thought that the number of transistors that can be placed inexpensively into an IC doubles approximately every … Read more

NORAD tracks Santa using Radar, GPS & high speed cameras

Only a few more sleeps left now until Christmas eve when Santa sets out to deliver toys to kids and gadgets to us geeks! :0) But did you know that modern technology actually allows us to track Santa on his journey?

santarudolphpresentsxmastree

Last year I stumbled across this brilliant website from NORAD.  With no expense spared, every year NORAD track's Santa in real time as he delivers presents around the globe. I for one am hoping for a new GPS, as my current one decides to stop working when I’m close to my destination!  My kids love this site, and it ensures they are in bed on Christmas eve within good time.

Now we come to the logistics of the whole thing.  If he was simply to travel in a circle around the Earth, then that’s about 25,000 miles, however, to visit every child's home in the world means that he would more likely travel around 4,670,193.27 miles in 24 hours!  That means he either has to travel faster than star light, or install a Read more

3D Printing workshop at OSHUG Camp 2011

OSHUG           OSHCAMP October 2011

                3D Printing Workshop



Last month, DesignSpark sponsored OSHCAMP.  One of the workshops was 3D Printing.

Did you know that you can build your very own 3D printer for under £500!  Not only is it relativly cheap, but the hardware design and the software that you need to build one are all Open Source.  The DesignSpark team were so impressed, that we are planning to build one ourselves.

Pico Technology and DesignSpark celebrate Guy Fawkes night with sparklers!

Our creative friends at Pico Technology had some fun with some sparklers on Guy Fawkes night this year!. My only question is how they managed to light them all without losing their eyebrows?!

Every 5th of November, the Britsh celebrate Guy Fawkes night.  On the 5th of November 1605, Guy Fawkes was arrested for an assassination attempt on King James 1st, by trying to blow up the Houses of Parliament in London with a big stack of gunpowder.  Ever since then, every 5th of November, British people have celebrated the fact that King James survived this attempt by lighting bonfires and burning a effigy of Guy Fawkes. More recently Fireworks and Sparklers have become part of the celebration.

Thanks again to Peter and Tim at Pico Technology for these excellent pictures!
