Raspberry Pi - the $25 computer

Hmm. Anyone know how to make an OS that we can use specifically for lasers? XD
 





This uses an ARMv6 processor, it won't run anything designed for x86. Windows 8 will support ARM. M$ hasn't said which version of ARM as far as I know. When they say RaspberryPi will run Fedora, Ubuntu or other distros they mean the ARM versions.
X86 mhz & ARM mhz aren't straight forward to compare. The system requirements for ARM versions is different.
The power of the RaspberryPi is still limited but might not be as limited as it first looks. Plus keep in mind its $25 & this is the first version.

So basically what I'm saying is I doubt this thing will run a full distro of ubuntu very well.

6-20v input provisionally.

Brings a whole new meaning to the saying "bootable usb stick".

That ones bootable in the opposite direction. Its cute too - I could probably use one of those as an ion laser supply controller :)

Right after I finish Thor

Which will be finished after I finish the capacitor bank :P

If it was over a 1Ghz maybe. ~700Mhz is kind of week.

At only 128mb of ram it won't run any of the newer windows versions. You may get win2000/ME to run but it would be kinda slow.

Once I put ubuntu onto an old old computer with nearly the same specs as this (~700mhz, 196mb ram) and it ran really slow. It took over 15+ seconds to open any program, firefox took around 30 seconds for a blank window to pop up and another fifteen for it to completely open.

Numbers aren't everything. It's more about the architecture these days. ARM11 is a fairly new and highly optimized architecture for portable devices. Even though it may only be 700Mhz, I'm sure it's far more powerful then that old computer you described.

As for comparing it to a netbook, this is far cheaper and quite a bit smaller too. Although, the RAM might pose an issue for real multitasking. But Linux can be quite resource efficient these days, even full distros. Especially if you use a lightweight GUI framework.

The alpha boards are here! (These are not for sale)


The final version will be smaller, credit card sized. Same ports on ~$35 model B as these boards tho.

Alpha board video Not sure if everyone likes embedded videos. If I didn't use flashblock I wouldn't like it.

Has anyone else been eagerly awaiting these? November feels so long. Going to buy one the second its out. :san: Probably a few more a second after that.

Nice video. He's got Schrodinger's equation behind his head for some reason lol.
 
All the beta boards have already had the error corrected by hand by the RasPi crew.

I'm really glad the bidding has gone this high on the beta boards so far.
Buying a final board might be hard until production can can catch up with demand but it will be worth it since the massive popularity will create a nice large community.
Community support, add on boards, HD camera & lcd modules, software ports, anything it can handle open source will provide with a large enough community.

That's how he's gunna sell them for $25.. Get people to pay $1000 / board for a while and that will subsidize the cheap ones :p
 
Anyone want to take bets on the winning bid amounts? :pop:

£2,050 ($3194 usd) for #10. :san: Liz messed up the listing for #9 & 10 so they are only listed on ebay.co.uk but anyone can still bid.

I like how XBMC (tv media player) didn't seem interested in an port at all... Then they heard the RasPi storm approaching. Perhaps a little fear of being left behind.

Now they even posted a video of them correcting the beta boards. Hope we get a video of pick & place too at some point. :D

#01 has hit £2,000 in 1 hour. Sold for £3,500 ($5,361)
All together, the 10 auctions raised £16,336 ($25,033)

Think I'll wait for the price to drop....:whistle:
