The Raspberry Pi is a credit-card sized computer board that plugs into a TV and a keyboard. It’s a miniature ARM-based PC which can be used for many of the things that a desktop PC does, like spreadsheets, word-processing and games. It also plays High-Definition video.
Raspberry Pi Model B comes as a single board computer, as shown above, and is not cased. Accessories are not included, however can be ordered below.

No, but I'm interested in how good it would be for DSP in a cost/power/speed ratio considerations.

DARN YOU DWB; made me waste an hour surfing the Pi website!
Building something for Burning Man?

sucks for DSP thb (reckoned youd be faster to grasp this), funny for running android or linux. Its just a phone without the phone 🙂

We've been messing a bit with one at work, to compare it with our PICmicro based boards.
It is very strongly pitched at the UK educational market; the non-profit foundation that put it together are hoping to promote a return to proper 'computer/programming studies' in schools - kind of a revival of the mid-late 80's craze for kids programming their ZX Spectrums and BBC micros, by having a cheap, standardised platform.
For that purpose, the in built hardware sub-systems (display,, LAN etc.) and Java support etc. make for quick results with an interface familiar to every school kid - and I would say that it is pretty cheap for what it is. Even then, unless you are going to embed it into some device, you could teach the programming skills just as easily on a regular PC.
As a custom DSP builders tool? - I'm with MHz on that one, those same built in systems just eat up resources from a chip that really isn't all that powerful to begin with, and you've got all sorts of stuff fighting for interrupts - not good for low-latency audio, like going back to DS after using ASIO! If I were building a custom stand-alone FX unit etc., I wouldn't want all that getting in the way; just as I prefer ASM for getting tip-top efficiency out of SM plugins. The PCB does seem to have space to add sockets for programming the ARM directly, so you might be able to overwrite the in built BIOS and SD card bootloader - but that kind of defeats the idea of the thing, and you might as well go for one of the other "blank canvas" solutions.
And if you want to put one in your custom gizmo, be warned! - I was asked at work to mock up a casing for one; there are only about 2sq.microns of unpopulated PCB and no mounting holes!

Well, the Ipad2 is used for DSP just fine, which is based on ARM A9. RPi is based on ARM A11, which over the A9 "Microarchitecture improvements include...: SIMD instructions which can double MPEG-4 and audio digital signal processing algorithm speed".
But until Android ICS/BG gets ported or an ARM A11 + DSP specific Linux port gets stable on Pi, I would bet getting a laptop/Mac Mini i3-7 board would be more efficient if you would consider all the time & power costs... maybe 🙂

colleges of mine like em too, theyre the more standard computer people. (using them to do home theatre mounting on tv and stuff). Prolly for me theyd be running out of headroom and memory bandwith, only to power the cheapest adc and dac ever. 🙁
Last news was android does work but the sound had issues..
Yup, that's pretty much what I did too - by the looks of it, he found exactly the same handful of places around the board edge where you can get a mm or so of clearance without fouling anything.
Doing a fully enclosed case was a bit more tricky though - I found it useful to use the bezels of the protruding sockets to help support a couple of sides. Luckily we have a laser machine at work - don't know how I'd manage without it. (that and my vernier - most of the free CAD modes I downloaded to "save time" drawing were hopelessly inaccurate).
This one has to be my favourite though...
R-Pi case by Biz
...though I imagine it rattles a bit, and I hope the voltage regulator doesn't get too hot! 😉 😈

I don't know about this board but I have an Android tablet based on an ARMV5 (800mhz) cpu and it is barely usable to check if you have email thru the wifi internet connection, (if you're close enough form a wifi spot... meaning you're sitting on it!) but don't even think about opening it or answering to it... with pictures embeded in the mail, it takes ages to open...and if you wanna dare to answer, free an hour of your time cause of the freaking virtual keyboard... what a pita...
It reads mp3s and flvs but with lag when the video has too much details or is in a high resolution...
I tried a few music apps... no luck... all were making the cpu to lag or freeze...
I would say an ARMV7 (1ghz) is the least to consider if you wanna run some music programs...

Older androids yes, ICS v4.0 is supposed to be better. The biggest issues was the lack of standard hardware, unlike iThings.
Besides, I wasn't considering the PI for playback, simply number crunching.
Trog, let me know if you want me to smuggle these out of the USA for you: https://tindie.com/Dichstudios/raspberry-pi-case/

Seems to be able to run atleast on plugin well :P But then again latency is kind of a big issue.
Tzarls ·
They say it can run on batteries?
I was thinking thay maybe it could be used like a cheap recording rig for the road - a couple of solar panels, a SD card and some simple software to record audio, and maybe a small LCD like the ones used on those "digital photo keychain" things.... ok, maybe not the cheapest recording rig, but could be a nice project.... I still have to wait for a couple of weeks to get mine.

How about mounting holes + VGA connector? From VIA also:
