Nerds assemble! Raspberry pi close to launch date.

Arduino Pro Minis run at 16MHz iirc

Yep, it does. I wasnt sure which versions of ardunios people were using for this, so i had a look about and found the fastest one i could (around 60MHz)

Edit: actually, i think the fastest may be 32MHz, i was looking at other atmel chips. Whichever it is, the Pi has a clock speed at least 10 times faster.

For those of us who, for whatever reason, weren't able to place an order for one of these right at the start, it is looking as if we will now have to wait up to two months before we can get our hands on one, which is a shame.

Let's just hope they find a way of increasing production somehow.
 
Clock speed isn't really that important, it's what the cpu is doing, although saying that I do think a Pi running fully-fledged linux could do it, depending on other system workload/interrupts.

The Arduino's run a 'tight loop' polling system, essentially an infinite while loop, this gives very good response, based purely on the size of the loop.

The Pi's will run full linux so there are quite a few layers to get down before it actually happens. But firstly the difference in power is significant enough that you could probably do it (with a caveat that once in a blue moon it might take that bit longer to do something than expected, which can cause issues), but it's always possible to port one of the real time kernels and/or play around at the driver layer where you can get much more accuracy/defined timings.
 
Apparently there are some real time kernels, we might be OK actually. If they run fine then I imagine, we won't have many problems apart from a bit of time jitter.

They could also sell the bits so people can put it together themselves.

Whilst im no electronics expert, surely that would be near impossible given the size of some of the connections required, especially on parts such as the processor?
The lack of profit is probably the reason they cant just up the production, I suspect its not quite as simple as just telling the manufacturer to produce another 100000 boards without some kind of payment.
 
It's a layered PCB too, you'd need some mad soldering skills

Edit: If want to send a hundred thousand quid the foundations way I am sure they'd be happy to ramp up production ;)

Why do they need more money when they have plenty of sales?

They should be meeting demand in a timely fashion or they're failing as a business.

They have been planning/designing/researching this since 2006 (iirc) I suspect the first lot of sales doesn't cover anywhere near whats been spent so far and they are also a charity not a business.
 
Having only registered my interest today, I am wondering how long it will be before I hear anything at all.

I would place a firm order if I were able to do so... even if it did mean a two month wait before it was actually available.
