    Is anyone here rocking a Cubieboard or Hackberry or anything of the sort? Been looking at some RaspberryPi alternatives that offer the same cost:performance ratio (I don't mind if it costs more so long as the increase in cost is reflected by the increase in performance). What do you guys think?

    Since I've gotten my raspberry pi, I've been what you could call obsessed with embedded computing and trying to find the best cost/performance/usability ratio.

    There is a not so popular company based out in Israel called solid-run that makes a 2 inch cube with a 1ghz quad core ARM processor (without overclocking) as opposed to a 1 core 700mhz core with the raspberry pi.

    http://cubox-i.com/

    I'm actually looking forward to picking one up whenever Newegg starts carrying them within the next 2 weeks or so. The included wifi/bluetooth/ir adds alot of capability in that small package. I will likely have a dedicated ssh / irc system running on it using a fraction of the power my computer uses now.

    Edit: After spending about $100 for a raspberry pi with all the peripherals to actually get it so its not just a bare board hanging around, its should be fairly obvious that $124 for essentially the same thing with better specs would be the way to go. The cubox includes the case, connectivity, micro sd card and power cable

    The Raspberry Pi is quite in the middle between the $200 all-you-can-eat boards (like the PandaBoard) and the Arduino clones for $10.

    There is one board that I would buy if I did not have a Raspberry Pi: The BeagleBone Black for about $45.

    BeagleBone-Black.jpg

    If you compare them:

    raspberrypi-vs-beagleboneblack.jpg

    BeagleBone elec. connections:

    • 3 I2C buses
    • CAN bus
    • SPI bus
    • 4 timers
    • 5 serial ports
    • 65 GPIO pins
    • 8 PWM outputs
    • 7 analog inputs
    RaspberryPi elec. connections:

    • 8 GPIO pins
    • 1 UART interface
    • 1 SPI bus
    • 1 I2C bus
    And the BeagleBone board is open source - so you can use it for any projects you want.

    Another nice looking board is the Cosmic Board:

    cosmicboard.jpg

    If I would have more free time I would buy the Parallella board.

    parallella.jpg

    This is about a ARM A9 processor which has got access to a Epiphany chip which consists of a scalable array of 16 RISC processors programmable in C/C++ connected together using a shared memory architecture.

    So this little board has a FPGA and an array of 16x700Mhz = 11.2 Ghz processor grid.

    If you are able to get your c++ code using all the cores.

    But a perfect and cheap start into massive parallel computing.

    Edit: Added the BeagleBoard black image.

    Arduino clone for $10? Where? I'm still searching a way to setup a small clustered netwerk here for learning purposes.

    Ebay and cheap China resellers are your best friends.

    My Pi is taxed.   Runs the VPN... Runs Squid... Runs some other proxy and filtering inline.

    Overall, the throughput straight remote network is lacking and CPU ceiling and above gets hits quick and hard.  Definitely in the market for something with more oomph and ability to push bits faster with overhead for processing things.

    The Pi isn't bad for what I am doing.  Exception is the one image resizer inline that gets ill and slogs  with these modern designer idiot layouts and 500 elements.

    I'd wait a while on the Parallella - I'm an original kickstarter backer and mine has yet to arrive. They have at least started production a couple of weeks ago, but yeahhhh.

    On a related note, I have an odroid-u3, and it's pretty nice. Not as cheap as it looks because power cable/case/(microsd|eMMC) aren't included, and you also really need the IO shield if you want to do electronics stuff, but still quite nice.

    I'm surprised by the seeming lack of quad-core boards like these at this point.  Phones have been packing such.

    Lack of proper disk interfaces is unappealing also.

    CubieTruck is interesting but price point is rather high.

    Currently there are two main hypes floating around:

    • minimal always on desktop machine
    • technical/electronics hobbyist playground from LED to quad-copter and robots
    If you want to have a more powerful PC they offer you something like Zotac Zbox.

    If you want to have something mobile they offer you Ultrabooks and tablets.

    If you want to have something with a lot of drives they offer you NAS machines that are able to run a lot of stuff.

    If you want more network connections they offer you routers that can run OpenWRT.

    The niche with FPGAs (Field Programmable Gate Array) is filled with Parallella and other FPGAs like Alan.

    The niche with a lot of GPIOs is set with the BeagleBoard and copy cats.

    If you need more cores you can check Wandboard: Cortex-A9 Quad core with 2 GB of RAM or the OrigenBoard.

    Or even an eight core monster with a Cortex™-A15 1.6Ghz quad core and a Cortex™-A7 quad core CPU.

    BeagleBone Black is eating the Raspberry Pi for launch. More pins more power and the operating system is on board. The SDCard can be used for data only to save its life. I like the Arduino universe and the great community. You find code and shields for everythings. I will buy the pcDuino V3.

    My RPi arrives tomorrow! First on the agenda is rebuilding my HTPC.  Next project is plug my pair of 3TB drives into a dual bay USB enclosure and RAID1 those fockers.

    RAID1 over USB sounds like a bad idea. You will split the already small USB bandwidth in half.

    Cavalry has a great USB Raid dock: http://www.cavalrystorage.com/en-cahdd-d.aspx

    Code:
    With a choice of 4 modes, you can set up your hard drives in any available configuration for your needs. 
    Choose RAID 1 to mirror two drives for data protection, 
    RAID 0 for speed, 
    JBOD for flexibility, or 
    Spanning (BIG) for increased capacity.

    I have been using Olinuxino imx233 and A10/13/20 devices from Olimex. All of the boards can run Linux and their price range is from 22 EUR to 65 EUR (+VAT) depending on the features.

    For example, currently I have one Olinuxino-imx233-maxi (64MB RAM, 454MHz CPU, custom Linux distribution) running as home dns server, and one Olinuxino-A20-micro (Allwinner A20, dual core Cortex-A7, 1GB RAM, SATA interface, Debian 7.x armhf) as file server.

    I also ordered one of the Olimex devices to test it - A10-OlinuXino-LIME and it looks very good. I will consider making some micro servers from these, in addition to the Raspberry Pi.

    Olimex is a great company I will buy one of the Olinuxino boards.

    This is a beast for only 35€. SATA,native ethernet, 5V compatible and 160 GPIOs on four GPIO connectors!

    Power managment is great:

    Code:
    A10-OLinuXino-LIME can be powered from three sources:
        +5VDC voltage applied PWR jack
        +3.7V from LiPo re-chargable battery connected to LiPo board connector
        +5V applied to USB-OTG connector 
    
    Power consumption is as follows:
    
        LiPo 3.7V power battery: 1.2W
        +5VDC input power: 1.3W 
    
    Code:
    LiPo battery allow backup power supply when main power is interrupted. 
    A10-OLinuXino-LIME have power managment IC which charge the battery when main power is present, 
    when power is interrupted the LiPo battery automatically provide backup power supply. 
    Step-up converter prvide 5V for the USB peripherials too.

    @peterw the bet part - Olimex is a Bulgarian company and these boards are made here. It is always great to be able to support the local business :)

    Just the GPIO connectors are too tiny for my liking (1.27 mm pin to pin spacing instead of the normal 2.54mm), but i guess you just can't fit 160 pins in such small space otherwise.
