Oh, you have no idea. Seat of the pants isn't the half of it. It's really good fun and it's a massive privilege to be working on something like this, but I still have nightmares about Raspberry Pi several times a week. (Being buried under tons of them in a warehouse, shipments falling out of mail boats and sinking to the bottom of the sea, and free-form ones where all I dream about is stickers and boards with no context.)
I need a holiday.
Too much wine and rich food before bedtime i think. send me your next review hamper and i'll take the weird dreams hit for you
Re: Just an honest post.
I thought I'd add some interesting facts to put things into scale! Please correct my maths if I've got it totally wrong...
-----------------------------------
I propose a new internal unit of measurement, r-pi (one r-pi is = 85.6mm the longest side of the pcb - I know that's not including connectors which stick out a little but hey).
After the 1st 10k run of boards, Liz will have 856 meters of r-pi!
When they get to 9,401 r-pi's they have reached a mile high if placed end to end.
The worlds tallest building - Burj Khalifa @829.84meters is equal to 9,695 r-pi, that's not scary is it! Already taller than that.
Empire State Building @381meters means that 8,902 r-pi will be twice it's height!
Big Ben @96.3meters is only 1,225 r-pi so with only 9k of r-pi there will be 8 times the height of Big Ben.
What heights can the r-pi reach?
Ben Nevis (highest point in the UK) @1344meters is only 15,701 r-pi (so by the 2nd run!).
Everest (Highest point on earth) @8848meters is going to need 103,365 r-pi to reach...wonder how long that'll take, before the end of the year, who knows?
The International space station is around 382km up, so 4,462,617 r-pi should just about do it!
@Liz ok...don't think I'm helping with the nightmare situation here, sorry.

Some people have just too much time on their hands. Now find out the weight of a raspi and calculate how many to the ton

Re: Just an honest post.
I think a more useful (?) measure would be the power used.
Battersea Power Station came on-line in 1933, and by 1957 had a capacity of 509MW. That's (obviously) 339 million Pis at an average of 1.5W, or about five each for everyone in Britain. Now it's an art gallery.
Drax, with 4 GW, can power 2.6 billion Pis, so we'd need three Drax's for one Pi for everyone on Earth.
Someone else can do the sums to find how many Pis per square meter* could be powered continuously by sunlight with battery storage, or how many Pis Katrina would have powered.
* r^2, obviously

Re: Just an honest post.
If we had figures for the R-Pi in flops (although meaningless), we could work out what computing power the first 10k of r-pi's would achieve. Also, would be interesting to see how it's flops/watt compares.
Still, the R-Pi does make even an energy saving lightbulb a power hungry monster. Since you can't do much with just a R-Pi, the power values are difficult when you factor in the peripherals.
No doubt Liz will be able to testify to the weight of 10k of R-Pi very soon (here's hoping anyway).

Re: Just an honest post.
i've seen bogoMIPS somewhere around here.
Re: Just an honest post.
From http://www.raspberrypi.org/arc.....78#more-78
Calibrating delay loop... 499.71 BogoMIPS (lpj=2498560)
