Well, it's finally gone into production. The Raspberry Pi.
A credit-card sized computer, with a USB socket, HDMI output, ethernet connection, SD card slot, and lots of other goodies. Yours for $25
Here's the website, a few minutes ago they posted the first video of one of these things actually booting up for the first time.

That is so cool! Here's betting that it finds a hoe in places they never thought of

Are they fine hoes?
So my raspberry is expected delivery 16th April, just in time for my birthday. I'm such a geek. |

Very fine hoes as a matter of fact. One is stainless! They are both very sharp too!
I went to the site, but it wouldn't let me order. Looks like they are inundated with orders and interest. |

They're selling out fast;
//downloads.element14.com/raspberryPi1.html?isRedirect=true
"Following the successful launch of Raspberry Pi Board B this morning we've seen unpresidented levels of interest in this product. Stocks from Raspberry Pi of the initial production quanitiy are limited and these have already sold out. For those of you who have already pre-ordered, we will let you know in the next few days when you can expect your delivery. We're working very closely with Raspberry Pi to ensure we meet the demand as soon as possible. We will be one of the first to have Raspberry Pi's in stock and delivered to you, so if you haven't been able to pre-order, register your interest below so we can let you know as soon as you can order again and keep you updated with the latest on availability.

| My question is how much will it cost when you add a box, keyboard, monitor, etc.... might make as much sense to buy one of those $100 laptops being distributed in several countries ... |

| Not intended as competition with all the available consumer hardware, more as an encouragement for youngsters to go geek. |

What I want to do is put it on top of a motorised lego car and attach a web-cam to it. Then leave it sitting the middle of my house.
Then, I want to log on from anywhere, and see my little car webcam. And click a few arrows and have it drive around my house broadcasting me a video feed from inside my house.
And you know... All I've got to do then is attach a little screen and speaker to the front of the car and broadcast my face and voice, and I'll have a virtual version of me that I can move around my house from anywhere in the world.
I'll never have to go home again. Daddy can work late every night.
In fact, this is great... attach a robot arm on top of that and I can even feed the cat remotely. (Although, it might freak the cat out when he sees me approaching as a disembodied head attached to a lego-car, trying to reassure him with my robot arm)

I suggest laptop battery (or four), and create a litte docking port with sprung contacts you can reverse the car into when not in use. |

Yes, I've been thinking about that. I'm looking at how my robot vacuum cleaner does it. It's got a rechargeable battery and when it detects the charge is low, it finds its way home to the docking station (using an infra-red beam) clever stuff.
You could use this in conjunction with a system of 'retracing steps' back to the docking station.

If you "retrace steps" you'll need it to turn around and head for the recharger when it still has half a charge left.
Why not add a GPS locator and have it take the shortest route back to the docking station? You might also have it use a "dead-reckoning" system to locate itself so it can calculate distance and direction.
And you might look into that magnetic plug thing Apple has on laptops or those new cell phone charging stations so you just need it to make contact to recharge, rather than having to actually engage a prong/socket system.

GPS on the best day gives 3m accuracy, which is not even close to good enough. In a building...it gets worse. |

I was thinking running an 'as the crow flies' algorithm against the outward route to calculate the straight line route back to the recharger. That way it's not just replaying every single step in reverse.
Also, I only need to get it close enough to the charger so it'll see the infra-red beam, as soon as it sees that then the 'home-in' piece comes into play, and it positions itself close enough that the magnet can engage the charger prongs (similar to my robot vacuum, I love that thing!)

Yes -- that's what I was thinking with the second suggestion of a "dead-reconing" locator calculation ... I look forward to seeing video.
BTW: you mentioned using a Lego car -- can you do something similar using Lego's own Mindstorms programmable system? |

Yeah, the thought occurred to me. My son was at a Lego workshop a couple of weeks ago, they were using Lego stepper motors and sensors connected to a laptop via USB, and a simple graphical programming language, similar to 'Scratch' - I'm not sure if that's Mindstorms or part of the 'Lego for Education' thing.
Although Mindstorms coding would make it easier to control the Lego motors and sensors, I'd probably need to code for the wifi and webcam piece (and route-finding) separately. It'd be easier to have all the code in one place like Python, and then use an API to control the motors.
I'm still throwing ideas around - I should probably think about patenting my "disembodied human cat-feeding (and comforting) device" |
