found one online store in sweden and they want 65 bucks for it lol
[QUOTE=M_B;34236646]uh, maybe because it's in the op, did you not read it?[/QUOTE]
The OP is wrong.
In any case, even if you could just lego these things together; you'd end up with a distributed cluster which are pretty much useless for anything other than highly specialized applications.
Does anyone know of any good (cheap) small screens that would be compatible with this?

that's not really what i was referring to. i honestly didn't bother to look up the background behind this thing but i know it's something you [I]can[/I] do, even if not with this particular product. you know like a farm
OK gosh
[QUOTE=Jallen;34208261]Well, it's not really electrical engineering but computer programming that you should be looking at.
From what I've seen, Python is going to be the main language used on it, but it supports several other languages as well (and compiling compilers for other languages written in existing supported ones should be possible too).
My recommendation would be to learn some Python since it is really a good beginner language.
Unfortunately, I have no idea whether it will use Python 2.X or Python 3.X, which is important because they are significantly different.
Still, here's resources on both versions (I reckon it's probably 2.6 they are using but I can't be sure)
2.6 - [url]http://en.wikibooks.org/wiki/Non-Programmer%27s_Tutorial_for_Python_2.6[/url]
3.0 - [url]http://en.wikibooks.org/wiki/Non-Programmer%27s_Tutorial_for_Python_3.0[/url][/QUOTE]
No no, I don't mean the programming for it, I mean the actual making stuff with the board - I see people on about wanting to connect screens and extra keys to it and stuff, and I want to learn how to do that.
Stuff like, what should I need to know to say, power this thing off a 12V battery? My knowledge goes as far as to say dump a shitload of resistors or a zener diode or something in their to bring the voltage down to 5V but people have much more elegant solutions involving voltage regulators, etc.
They said on the website you could run it off 4AA batteries, which comes to 6V. Am I correct in thinking that you could just ram some 4AA batteries in parallel connected to a microUSB lead and plug it into the board and it'd just come on, like magic?
Or do I need some boosting circuit, or ..current limiter or something so it doesn't explode?
That's the stuff I want to learn!

Well, the board has DSI connectors on it, and according to the wikipedia, that format is supported by manufacturers like Nokia and Samsung.
So, you might be able to buy a replacement screen for a phone and just solder it straight onto those connectors? Add some power and you now have a working screen. Maybe.

You don't mess with the circuitry.
If you want to power it off a 12v battery, you make an adapter to its micro-usb power in.
If you want to connect a screen you do it through its HDMI port.
If you want to have some form of input, you use the USB ports.
When you buy the raspberry pi you are not buying a circuit board, you are buying a small computer with no casing.

I thought the board was designed for people who wanted to mess around with the hardware as well as with the programming, otherwise they would have no reason to include the DSI or GPIO ports.
I'm pretty sure the reason that they are there is so if you want to mess with the circuitry you can [i]mess with the circuitry.[/i]

Does anyone know if Chromium has touch-screen support ( and if a touch-screen would even be compatible with one of these )?
[QUOTE=nick10510;34242315]Does anyone know if Chromium has touch-screen support ( and if a touch-screen would even be compatible with one of these )?[/QUOTE]
If you can get ARM software for reading the touch screen input then sure
[QUOTE=nick10510;34242315]Does anyone know if Chromium has touch-screen support ( and if a touch-screen would even be compatible with one of these )?[/QUOTE]
The only way I can think you could do a touchscreen would be through either the USB or the GPIO headers, both cases you'd probably need to make drivers yourself for it.

It's designed to teach software, not hardware.
You really think a school would buy a bunch of these only to let ditzy facebooktard A drip solder all over it?
[editline]16th January 2012[/editline]
The GPIO ports are a bonus, this is the BBC micro not Arduino.
[editline]16th January 2012[/editline]
Also, aren't these coming with cases?
[QUOTE=benjgvps;34228375]If you're planning on buying a screen, a keyboard, a battery and building a case... You're forgetting about these things called "Smartphones". You can find 2 year old smartphones for around $150 if you're lucky (I got my Nexus S for around that much), which might end up being what you'd pay after buying everything. They'll have a smaller casing, a faster CPU, Wifi, better battery life, ect. For a wrist computer, a used Android phone / iPod Touch with an arm-band would be much more practical than something that looks like a brick-sized IED. A true Android-based watch is available (Motoactv), which some guy hacked to run regular Android applications.
If you're interested in using the Pi for headless purposes, check out what this guy did with a tiny, cheap TP-Link router: [url]http://www.minipwner.com/index.php/what-is-the-minipwner[/url]
It has Gigabit Ethernet, Wifi N, OpenWRT compatible, serial header, one USB port and it's powered by MicroUSB. With the battery pack he bought, it gets about five hours of usage. It might be possible to use it as a very light webserver or some sort of NAS device with some firmware modifications.[/QUOTE]
You won't have half the fun with a smartphone, the fun in this is doing it all yourself and teaching yourself how the hell all this works, don't ruin our fun.
And yes they are coming with cases.

Well, the thing that interests me about this is learning about the hardware and how to put everything together, and while the board may not be intended for that, it's cheap, and expandable enough to let people who want to do that do just that.
Plus, it could let me learn more about working with software that's closer to the hardware, which also interests me. I wouldn't buy this just to learn Python, my windows PC can do that, I'd buy this so I can learn about the electronics of it, how to expand it, and finally how to program it.
i'm going to throw a 32GB SD card onto this and use it for a small server
So many ideas for this thing, yet i got a feeling i will be disappointed.. Lets hope its just a feeling and not the truth
[QUOTE=Protocol7;34243041]i'm going to throw a 32GB SD card onto this and use it for a small server[/QUOTE]
Reminds me, I should probably use one of the emulators/virtualisers that's loosely based on the board's specifications to try and cook up a [URL="http://library.linode.com/lemp-guides/debian-6-squeeze"]LEMP[/URL] webserver setup.
I'm probably gonna screw up multiple times, but that's sometimes part of learning.
Yeah I think it could be used for simple things like a webserver or a DNS server or simpler things like that
[QUOTE=Protocol7;34243736]Yeah I think it could be used for simple things like a webserver or a DNS server or simpler things like that[/QUOTE]
For things simpler than a webserver or a proxy, it would probably be easier to buy a cheap DD-WRT/Open-WRT compatible router.

[B]You can't run windows.[/B]
You especially can't run Windows 8. I mean, hell, this thing only has 128/256Mb of ram, that's like the minimum for XP iirc.
You can't run XP.
[B]You can't run anything that runs x86 - as in, things you run on your desktop computer, even if it's linux, will not run on this.[/B]
Half the stuff you plug into it might not work due to the lack of drivers for it.
You can run [B]anything designed for the ARM processor[/B] on it, eg, mobile versions of linux, Windows CE, embedded operating systems possibly, [B]providing the applications are within the abilities of the system.[/B]
You can run 3D games on it, provided they're ARM compatible. Eg, that quake demo.
You can plug the RPi into various different things to expand it provided you're able to hack your way through it, eg, raw LCD screens, servo motors, LEDs, etc. See [URL="http://www.raspberrypi.org/archives/411"]Gertboard[/URL].

99% the questions people are asking on here can be answered with:
a) Yes if you can find a version for ARM
b) No.
Also I'm gonna hook mine up to my TV with an aerial and use it to play all the films I have on my computer on the big screen :v:
I have tonnes of films on my PC and no way to get them onto my TV short of transferring them to a laptop and plugging it into it, which is laborious. This way I can download/flash drive all of my films onto the pi and solve all of my problems.
Is there a LAMP/LEMP server package that is compiled to work with ARM, or am I going to have to compile this all myself?
