World's First Linux Computer In A CF Card 113

Posted by timothy from the please-don't-format-in-your-camera dept.
An anonymous reader writes "LinuxDevices reports on the world's first Linux computer to fit inside a CompactFlash card. The 'Compact Flash Computer' (CFC) can be mixed and matched with third-party CF cards to instantly create minuscule Linux systems based entirely on CF cards. A wide variety of third-party CF peripheral cards can be used with the CFC, including RS232/485, Ethernet, Bluetooth, USB, 802.11, GSM, GPRS, GPS, and more. A combination power supply / bus expander module on a separate CF card, as well as a tiny 8-slot CF card backplane, are available as options." An anonymous reader adds "The card is based on a Freescale MPC5272 system-on-chip processor and contains 32MB of SDRAM and 8MB of Flash memory, and it comes with a uClinux based operating system and GNU development/debug tools."

Just slot your French translator card into your portable wearable computer.

    In the short term, this could be part of a counter-revolutionary movement against the notion of ubiquitous wireless computing - rather than making most devices dumb terminals that rely on a remote centralised server for their data repository, this could effectively make any dumb piece of hardware a fully fledged computer, even without a network connection (indeed, it might be preferable for security or logistical reasons not to have to worry about a network).

    I wonder what kinds of things we'll be able to do with this type of technology when memory cards can hold 100s of gigabytes of data?

    You know, this could be a great way to bring upgradeability and extreme customizeability to portable devices.

    One could imagine a sleeve where you plug in a cpu card, some data storage cards, a wifi card, and so on. Sleeves could be upgraded to provide new peripherals. You would use firewire, usb or some other generic protocol to provide the interface between the sleeve, the cards, and the outside world (possibly using stub cards that transform a cf card to a usb data storage card).

    That way when you need a bigger screen, you'd buy a new sleeve and dock your old cards into it. Cpu not fast enough? Just upgrade the cpu card, no problems with having to replace the entire pda.

      Why hasn't this been done yet?

      Because most people, unfortunately, are not geek hobbyists, and think of computers in terms of application, not of mechanism. To them, this reconfigurability is just additional cost, complexity, and fragility to get a "follow the directions to assemble it yourself" device that performs some task that they want to do, like store lists of phone numbers. Sure, it drives us bonkers that we don't have a pretty interface and better support for the I2C bus (or internal USB in cases), interesting input (knobs, sliders, etc that can be interfaced with) devices, cheap interesting output devices (LED/LCD/VFD front-panel displays), thermometers, and the like. The typical computer user, though, doesn't give a damn about extending or reconfiguring their computer, because they want to accomplish a task, and don't really want to "figure out what to do to their computer to accomplish that task".

      Sigh.
      • Reconfigurability is only additional cost if it takes much effort. If increasing your CPU power is just as easy as putting a new CPU card into your "computer" (i.e. less complicated than getting cash at a cash machine!), then the non-geek will appreciate it. You don't actually have to think, just buy the card which does what you want, put it into a free slot, and voila.

        Unfortunately, I suspect the reality would again be plug&pray instead of plug&play.
    • When I read about "sleeves" and "cards", the idea that comes to my mind is cheating in poker. A micro-camera in a ring in your finger shows the cards as you deal them. Bluetooth connection to the computer in your pocket, which calculates the odds. Another bluetooth to your glasses, where a small speaker near your ear tells you how to play... From now on, beware of players who turn the stone in their ring towards the palm side of their hand when dealing!

      Hmm...speaking of LCD displays...that's actually a very interesting idea.

      Currently, smartcards have one huge hole for use in secure environments -- they have no secure user-input or user-output channels. This means that if someone sets up a bogus ATM/card reader (which has been done oh so many times), they can swipe your PIN and since the interface, including hitting "OK" or not is all done through the reader, can hit "OK" for you.

      But if you can build a small computer with a simple interface (CF is a good choice, though a smartcard interface would also work), you can slap a display on it (actually, all you need is a calculator-style alphanumeric LCD strip) and a nine-button numeric keypad. You can enter your PIN directly to your card, and you can trust that the price being displayed on the card is the price that you are actually paying, and the payee being displayed is actually who the money is going to.

      For a long time, I've been wondering how long it will be until smartcards become standard for sales. The attacks on smartcards are largely doable because of a lack of untrusted readers (as I said, no keypad or display on-card). Smartcards are great for e-commerce, where you can have a reasonably trusted reader in the form of your computer. I figured that one day AmEx or someone will partner with Dell and Dell will start bundling smartcard readers with their systems (the cost of a smartcard reader is very, very low, and the potential savings with not having to deal with constant fraud attempts on credit cards, and the ability of vendors to actually trust and allow purchases coming from, say, Nigeria, is a significant benefit). Nobody's got around to shipping lots of computers with smartcard interfaces -- but *lots* of computers have CompactFlash interfaces. All that's needed is an open standard for communicating with "smartcard on CompactFlash", someone figuring out where they can get their paws on some cheap, durable LCD displays, slap some buttons on it, and you have one hell of a compelling commerce mechanism to replace the credit card.

      FWIW, while I'm sure credit card vendors have no interest in allowing such a thing, a smartcard vendor could provide actual privacy, not knowing about each one of your transactions, since your transactions cannot be (reasonably) forged.

      God, that would be cool. Anyone know how many mW CF can provide?

      • Nobody's got around to shipping lots of computers with smartcard interfaces

        Umm, gotta disagree with you there, every computer purchased by the US DoD is -required- to have a smartcard reader. Dell has a keyboard (model SK-somethingorother) that has the card reader built into the keyboard.

      Second, given the extensibility of this product, and the fact that it is solid state plus low weight, it can now be used in places that no normal PC would be able to go. I.e. high pressure, high heat, etc. Why? Because it can easily be enclosed in a protective casing to do so.

      The potential advantage of this CFC thing over the gumstix [gumstix.com] (which is cool) is that the stupid client USB port on the gumstix means that it's going to be a struggle to attach USB peripherals. With the CF bus, I should be able to attach CF peripherals to the CFC easily. Presumably the next gumstix will based on a part with the new USB 2.0 controllers which can be switched between host and client modes. This would be good.

      OTOH, the gumstix ARM should be substantially faster than the CFC Moto ColdFire part.

    During business hours, it also captures and stores any interesting packets that it sniffs, including passwords.

    Late at night, it uses the mac address of the legitimate device (so nothing looks fishy) and makes an IRC connection to a private chat channel where it just silently listens for coded commands from its master, including commands to upload anything interesting that it captured today.
