Raspberry Pi!

I have to admit I’m getting really excited waiting for this┬áto be released…

This pic from the official site, not taken or owned by me... if there's a problem with me using it, let me know and I'll take it down!

It’s a tiny little credit card sized computer, designed for teaching kids programming. Despite not being a kid (well, not physically anyway) and already knowing how to program, I want one.

Or several… they’re only going to cost 25USD for the basic Model A or 35USD for the slightly more powerful Model B. But despite the ridiculously small size and price they are capable of playing full HD video, which is more than my netbook can manage. This is made possible by the fact that the Raspberry Pi is using a mobile phone processor rather than a normal PC processor. (The main processor core, an ARM11, is very similar to the chip in my HTC Wildfire, but the one in the Pi runs a bit faster and is coupled with a very powerful graphics processor to handle video decoding and 3D acceleration).

The idea of it, a simple little machine that plugs into a TV and is easy to write your own programs for, takes me back to the old home computers of the 80s and early 90s that I first learned to code on. I did most of my learning on a ZX Spectrum +3, which is probably still in the wardrobe somewhere along with a BBC Micro Model B+ that I acquired a bit later. They were laughably primitive machines by any sort of modern standard, but I miss the simplicity and accessibility of them. You could turn them on and immediately start writing a program, and if you were curious there was plenty of information out there that would let you learn how the machine worked inside out.

The Raspberry Pi won’t be quite the same as that. It will still run a modern operating system (some form of Linux; Windows won’t play well on hardware like this) and elements of it, especially the graphics chip, will be too complex for most people to learn fully. But it seems like it will be a fairly large step in that direction. The Model A and Model B naming, in fact, is a nod to the first two versions of the old BBC Micro.

Normally when I want something like this, I’d probably buy one eventually, but have nagging doubts at the back of my mind. “You’re already working with computers all day”, they would say. “Why do you want to spend your free time hunched in front of a screen playing with code as well when you could be enjoying so many of life’s other rich pleasures instead?”. “But I want toooo… it’s fuuuun….”, another voice would argue back in the tone of a whining five-year-old.

This time, though, I’ve neatly side-stepped that whole dilemma by offering to supervise a project at work involving Raspberry Pis. So I can legitimately play with, um, create something valuable and useful with them in work time and even get paid to do it. Yay!

Can’t wait for the release date… which is hopefully January 2012 :). Next problem is how to actually get hold of one… seems I’m far from the only person to be disproportionately excited about this, and I wouldn’t be surprised if the first batch sells out pretty quickly.
