Space Cube – the World's Smallest Linux PC 265

Barence writes "Meet the Space Cube — the world's smallest fully functional PC. Primarily designed for use in space, it somehow manages to cram a working PC with USB ports, card readers, audio outputs and proprietary interfaces into a tiny cube chassis measuring just two inches square. It runs a basic Linux front-end, which the blogger takes a look at, and there are some great photos of the device being loomed over by everyday objects like coffee mugs and cellphones. It has connections for controlling various electronics used by ESA, NASA and JAXA, but it will also apparently be for sale to the public soon, for use by amateur engineers and robotics clubs."

    In terms of volume it looks bigger than a beagle board + CF card. The Beagle board is 3" square, but it can be a lot less tall than this. It also has a much faster CPU and (to me, most importantly, since it means I can actually connect it to a modern monitor) DVI output.

      Maybe 2 years ago this might have been 'Wow!' - but with the likes of the Eee etc around - the appropriate response is 'Meh.'

      Just some quick back of a fag packet calculation on the Eee put it at 9cm^3. Obviously, a lot more than this with its 5cm^3, but you do get
      * a keyboard
      * a screen
      * 3 usb ports
      * wireless ethernet
      * mouse pad
      * power
      * loads more disk space
      * 3 times the processor
      * etc
      all for 300 quid

      Which if you got rid of would reduce the size right down to a lot less than 5cm^3.

      No disrespect to the folks that put this thing together - and yes I would like one please - but... it's not rockin' my world.

        Of course not. And it also doesn't help that the Space Cube, unlike the eeePC, is totally useless by itself.

        It's wonderful to have a tiny computer, but if you need to slap on a monitor, keyboard, and mouse to use it it's really not all that tiny, is it?

        It also doesn't help that the real reason, in general (i.e., other than embedded computing environments) the reason people want small computers is portability, and this thing is hardly portable- sure, it's small and light, but given that it's totally useless on its own, that lack of size and weight is mostly irrelevant.

        Even for use in space, I still think it's a waste of, well, space. Either you're going to connect it to a real computer for display and use (with that big monitor and keyboard) or you're not, and all those jacks are a waste of space.

      Actually this stuff IS available to the general public.

      It's called the PC-104 formfactor and it's been around for decades. Hell I got a 386 with A2D inputs and digital in and outs as well as VGA, CF interface and audio interface in the basement that is slightly larger than that that I used for wearable Computing in the early 90's.

      It's not new or special. It's standard industrial PC gear repackaged and sold with a "Ooooooh space technology" marketing twist.

      • This is substantially smaller than the PC-104 form factor, which is 3.6" x 3.8". It did however remind me a bit of the old Intrinsyc CerfCube devices that used to be available a few years back, one of which I have in my collection of stuff somewhere around here.

      It is enormously expensive to launch things into orbit. Making a smaller and lighter computer saves on launch costs, and the weight allowance can be used for other things.

        Not necessarily. You could (for example) have them control all kinds of things with no peripherals attached for most of the time (that is, except in the case when a problem needs to be diagnosed).

        In case of a problem if there's need for diagnostics, you can then plug some small screen+keyboard and you're set to go.

        They're running linux so they should be ideal for monitoring sensors and reporting, transmitting ping/heartbeat signals for any kinds of devices, for controlling hardware, basically for anything that can run autonomously.

      I would think that the primary "big deal" would be programming talent.

      Way back when, the government used proprietary, government-programmed operating systems and software for stuff, and it rarely worked and it was difficult to find programmers to maintain or update the software. This way, by using a processor that can run a well-known, well-liked, popular OS that has literally millions of enthusiastic programmers available, it shouldn't be difficult to get critical software written or maintained.

      You also won't need to re-invent the wheel for common modules, and your programmers can therefore concentrate on the stuff that is unique to your application of the hardware.

    This is Not a PC.

    From the Manufacturer's web site, it runs a fairly standard MIPS SoC from NEC... a Vr5701. There is not x86 compatible CPU in there. Since it's MIPS, don't expect to just use RPM and install anything, and clearly it doesn't use RedHat. The OS might be derived from RedHat, but I suspect it's just bad journalism (everything Linux is RedHat, right?).

    I'm not saying it's not cool, but it isn't a PC. And I think if you want a Space capable device, you'll have to deal with the radiation hardness yourself. has some perhaps more suitable chips that are rad hard (SPARC based).
