Raspberry Pi - Who's gonna have a dabble?

I like the car pc idea, I was wondering if a 7" tablet screen would work with it too, for car pc or whatever.
I'm more a hardware hacker, Id like to get one to finally get my head around Linux. Was curious to read that wine isn't compatible due to architecture, wonder how long before someone has a fix for that.
The "problem" with the tablet screen is that, once you buy a tablet -for the screen-, the SOC in that will probably be a lot better than the Raspberry Pi, defying the point of going for the difficult task of pairing the screen with the Pi.I'm more a hardware hacker, Id like to get one to finally get my head around Linux.

Been reading few articles about the pi and one says that the graphics chip is twice as powerful as the one found in the iPhone 4s...
Hmm from what I understands it also needs to be to support full hd. It has video formats hardware supported because the CPU itself is to weak for decoding.It also only has 256MB RAM, which is a lot less than what we find in the tablets.

Anyone else think the 2 choices of retailers are a bit odd? I'd never heard of them before today!

A: CAPITALS!! lower case

I'm signed up waiting for an email to tell me when there's stock. My plan is to see if it can be used as an in car computer (with touch screen), however I'm likely to mess with it for a couple of weeks and then sling it in a draw.
I excitedly showed my wife the 20 quid PC, she glanced over the top of her iPad and muttered something about sad w
ker. I might get several just to annoy her.

Back on topic, the power supply will probably be an issue for a car computer as it needs to be heavily rectified.
It shouldn't do. Car electrics are already heavily rectified to 12v dc. The rasp pi uses 6v dc I think. (it can run on 4 AA batteries, I was considering its use in a low earth orbit satellite and was doing a little research Back on topic, the power supply will probably be an issue for a car computer as it needs to be heavily rectified.
It's also possible to solar power it, it only needs 700mA)Unless your concerned about surge? An inline fuse should keep it safe.

Not good for a LEO sat, radiation would cause it various problems. Tiny feature size, latch-up, no error detection and correction etc. Better to use an old school relatively rad-hard plus one of the more resilient FPGAs that can run a soft processor (the Mars rovers have done this to very good effect). That way, when an error occurs you can wipe it, scan for bad cells and patch around it. Generally speaking, satellites don't need masses of computing power.
It would be kinda funky to remote synch an mp3 or video player in the car, from the house. Sleep current of ARM cores is tiny and would take years to flatten a battery.

I didnt mean a LEO for commercial use I was thinking a LEO for schools too program (with attached sensors, cameras etc). Critical sat control systems would have to be seperate.It would be kinda funky to remote synch an mp3 or video player in the car, from the house.

Some UK uni's have been experimenting with using Android smart phones as sat control computers.

Might buy one although I'm having enough sleepless nights dicking around with Arduino for my final year project at Uni (electronic engineering / computer science degree)
My project supervisor is exploring the use of Raspberry Pi as a teaching aid, planning to make it a compulsory purchase for his classes like a textbook (teaches low level programming /embedded systems programming etc)

I placed an order for mine on Wednesday; got the email Thursday to say that it's expected mid-April.
I have to admit that it was quite funny to see the Farnell web site fall over in such a way (I have had the occasional problem late at night when looking for components, but not normally during the day - and most of it!)
