Topic: Anyone Wanting to Try Rasberry Pi ? (Read 3 times) previous topic - next topic


No it's not a sex act (I hope)...  it's essentially an ARM processor on a board (Like Arduino the board) except it comes with USB, HDMI, a GPU etc.. basically a phone without a screen but with real
world connectors you see on computers, you plug your keyboard and mouse into it...

(without going into shock over questions like this... http://www.raspberrypi.org/forum/general-discussion/worthwhile-me-buying-a-pi-want-to-learn-a-language-for-running-calculations#p64804 )

What's peoples opinions? flop or possible success?.. of course $25 for a 700mhz ARM processor and GPU i'm going to eventually buy one out of curiosity, but for those who've not heard of it, have a look at this, they clam that they're pushing this at kids to get them interested in programming again, i don't see how personally,  I just want to write one for an extremely low cost low powered web server with 256 meg of ram, i can't quite imagine the Atmega putting up much of a fight.. of course this is not a replacement, the beauty of any Arduino board is the header pins to interface with the real world... so forget it, nobody's taking my Arduino's away from me NEVER!!!!....


Maybe some kind of hack on the Rasberry Pi to make it interface with Arduino? my electronics side of me says Rasberry what.... my geek side says, whoooooo $25 gets you a 700mhz CPU and GPU and 256 meg or ram which runs Linux direct from SD card... so to anyone who thinks this might be a threat to Arduino's future forget it, unless we see header pins to interface with the real world,  the rasberry pi will just be another event in the computer history calendar, let's face it an UNO board as of now will be just as suitable to do stuff on now or in 10 years time, you don't need to go faster (we don't run an OS on it...) with a phone or this rasberry pi, newer software comes along and the device will fail... if a new sensor comes along and we can't get the data off... that sensor fails :)


The Raspberry Pi is surely going to affect how people use Arduinos.  Just like the Arduino it appeals to the hobbyist on price and ease of use, but suddenly we can opt for a whole computer complete with operating system and video output.  I don't think Arduino can compete on price, but it does have certain strengths:

  • Plenty of I/O ports

  • Can run at very low power

  • Better suited to real-time tasks

I hope the RPi will stimulate some evolution among the existing Arduino species.  I think we'll see lots of Arduino-based I/O expansion boards for the RPi, for a start.  Perhaps we will also see newer Arduinos that play to their strengths, such as remote sensing or mobile applications, with support for Lithium Polymer batteries, solar panels, or low-cost rf communication.

In any case, it's a great time to be an electronics and computing hobbyist.


I'm waiting for the initial riots to die down.

Although, frankly I don't understand a lot of the excitement.  You've been able to get similar systems at not-too-much-higher prices for quite a while (in the form of linux-based appliances: routers, chumbies, pogo-plugs, etc.)  And if size isn't so much of an issue, you can frequently get a PC-class machine for free from someone who is upgrading.  I've probably got a half-dozen things lying around that could fill a "I want to learn python programming under linux" urge (not counting the actual computers that could run linux under VirtualBox or the equiv.)


I'm kind of annoyed at the choice of a broadcom chip which you aren't actually allowed to find out everything about without doing a deal with broadcom and signing NDAs (and probably paying a fortune). Seems counter to the sort of thing the project is supposed to be about (but no doubt it will be fun for people who like to reverse engineer things :-).


Here, here.

Yes, it's interesting and I'll probably buy one.  (After things settle a little.)  But, what about the Beagle Bone?  It's a bit pricey in comparison, and I don't know whether it does 1080p decoding, but otherwise, it's an Arduino running on a 700MHz ARM processor.  GPIO is already available on the BB.  It's an option for the RP.

So, if the AVRs were going to be threatened by a core clock speed makeover, that ship would have sailed by now.  Fact is, there's plenty you can do at 16MHz.  There's no need for near-GHz speed for many of these projects.  There's plenty of room for low-power processors.  Right tool for the job and all that.

I would also like to strongly second the discontent with proprietary chipsets, though I don't know that there's any option out there for hardware-accelerated 3D and video decoding that isn't going to be swamped in patents and NDAs.  That's what we, as a society, get for allowing the fancy HDMI, Dolby, and MPEG logos to sway us away from perfectly good open and patent-free alternatives.  Now, if you want to play commercial content, you have to be licensed to decode those formats.  That costs money.  To ensure those fees get paid, the libraries aren't available for free.  (Part of the Pi's cost is licensing of MPEG4/h.264 codecs.  No MPEG2 yet.)  And since there's no point in restricting release of binaries if the source is available, you don't get that either.  Which means you're stuck with the drivers and kernels made available to you.  Happy tinkering!  Far cry from the BBC micro in that sense.

Sorry.  Touchy subject for me.   :smiley-roll-sweat:
