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.

I think that part of the problem is down to the modern world, a world where the majority kids today inspire to be Rock Stars or Celebrities, rather than Astronauts or Computer Programmers, as it was in my day growing up in the early 1980's. What most of them probably don't relaise is that people like Bill Gates and the late Steve Jobs, were Geeks with more money of their own, than many countries have! and far more than most "celebrities" So what can we do about this! Well, Eben was keen to get the kids of today interested in the building blocks of technology, and make a product that would appeal and inspire them, and so, the Raspberry Pi was baked!
To most of us reading this, technology and how it all works is a drug, I'm certainly addicted!, I think the difference between me when I grew up, and the kids of today, is to do with the evolution of technology and modern media. Inspired by movies like Wargames and Weird Science, I pretty much had to build my own first computer from a kit, and I learnt how to write basic on it and I also used it for gaming. Today, games consoles are just that, you can't write basic on it.... the hours of fun I had writing things like "10 CLS, 20 Print " Pete is Cool!", GOTO 20...... ,today they are just off the shelf throw away commodities which a monkey could operate.
So this is the problem... there’s no real incentive or easy way for kids today to get introduced and involved in technology and computers at a nuts and bolt level, and if we're not careful, within a generation, electronics hardware and software design could almost disappear from the UK, just as manufacturing almost has. So taking the technology drug into schools, and getting kids hooked on technology from an early age, seems like the answer! Now, there are platforms like Arduino around which are great for introducing electronics to beginners, however these type of applications generally require some heavier coding, where as Raspberry Pi is more along the lines of the old school computing from back in the 1980's, when BBC Micro was king and so is easier for a younger user to get to grips with. Although I understand uf you want to, you can open up the Rasperry Pi and do alot more heavy programming on it.
So, Raspberry Pi is a great first step to get kids interested in technology and influence more of them to become electronics design engineers and computer programers of the future. Raspberry PI is in fact a registered Charity, and there are some big old school names involved with the Raspberry Pi project, including Jack Lang, who back in the day, was involved in taking the BBC Micro computer to market.
The sad thing is, due to the price point required to get this project to fly, it looks like manufacturing this in the UK isn't going to be possible now due to crippling taxes! Come on David Cameron and Vince Cable! these guys are a charity, don't gamble on the fate of UK Electronics and software engineering, please help these guys manufacture this in the UK, otherwise the custard I refer to in the title of this post may end up as pies in your faces....
My original comment from a week ago seems to have gone! Here is a shortened version.
This is great introducing micro-computing to schools and stimulating the growth of this area, but is it the right way?
My suggestion would be to have an emulated micro on the PC which drives a USB I/O pod. This will allow great visual displays of what is happening and allow interation with real hardware.
Yes it will be slower than a micro target, but I learned on a 1MHz 6502/6800 and Z80 which was fast enough.
Yes it will be tethered to a PC, but you can still learn about sensors, motor control, solenoid control, stepper motors, temperature control.......
It can also be robust and also cheap to repair a damaged USB I/O module if socketed components are used for the 'at risk' components. Reminds me of the "User Ports" we used to have on Commodore Pets and other early microcomputers.
The emulated micro can also be a special simplified micro to help with this initial learning stage and then be a more complicated version as the student advances, even emulating a 'real' micro. The language can also be assembler, BASIC, C etc., as required for the particular teaching stage.
In summary this would provide a versatile, robust, low cost solution which can lead on to Arduno and mBed.
Whilst projects like this are all well and good, one should bear in mind that not all electronics is digital and software! I don't wish to poor scorn on a well intentioned scheme, but in my view it misses the point slightly.
What does the 'raspberry pi' offer in terms of educational value, over and above the Arduino in any case ? Personally I feel that due to its simplicity and its limited nature, the Arduino is more likely to engender the need for some real creative thinking. The ability to solve a problem creatively is surely what differentiates the good engineer ?
Like many on here, as a boy, I spent many a happy hour building projects from those little paperbacks from babani, utilising little more than a soldering iron, some vero board and a handfull of discrete components. Back then, one could build things that you could not buy - nowadays the situation is reversed.
It is the fundamentals that need to be taught, not how to use the latest highly integrated chips. How many graduates these days could build even a simple audio amplifier, without recourse to an intergrated operational amplifier?
The concepts of digital logic can (and should) be taught at the fundamental gate level, using TTL to build up more complex functions, reinforcing demorgan and the boolean algebra which should be taught in parallel.
I remember seeing a video some time ago about the project and hoped so much it would come to market.
This SUPERB unit will rock the world and become a first choice for projects for millions of creators.
The creator's philosophy behind the project, explained in the video I saw, was an immediate 10+ and I am convinced that he will acheive so much more that he never anticipated with his creation.
The synergy that will be created by millions of users will give it all of its power
Looks to me like in a few years we will all be in the users group.
They are a bit behind schedule due to this manufacturing location issue, but hopefully should be availble very soon! If you want one sooner, A Beta Board went for £3500 on e-bay yesterday!

Anyway, that's my two penn'th

It would be complete with RTC and battery backup or super cap.
At that price, 700MHz processor, HDMI and ethernet, it is going to be next big thing.

That is SO cool! If only it sported a LVDS display connector so I could use the LCDs I have lying around...

Wow!! that is a great idea, so.... who is going to get one of those for their kids? I don't have kids yet but many of you are certainly blessed!
When is a first release date, anyone knows?
