World's Smallest Linux Box Fits in RJ-45 Jack

An anonymous reader writes "German electronics company Kleinhenz is shipping a network-enabled Linux system built into an RJ-45 Ethernet jack. "Picotux" has a 55MHz ARM processor, 2MB of Flash, 8MB of RAM, a serial port, and five lines of GPIO. It measures 0.75 x 0.75 x 1.4 inches (19 x 19 x 36mm), and weighs 0.64 ounces (18 grams), packaged in a metal housing. A wireless 802.11 version appears to be on the horizon, too. So, if you've ever wanted to network-enable, say, a robot, boombox, or model airplane, this could be the system for you." Is this really the world's smallest? It looks a bit chunkier than a tiny gumstix machine.

    I realize that others by now may have made products to do what I figured would be the smarter way to deal with massive amounts of wired hardware. But, since many companies and individuals are not encrypting nor using Wi-Fi out of fear of rogue waves going out anyway, does it make sense for the smart panels idea to take off again?

    IF that happens, and if these Linux jacks could be sort of like nano-bot security bots, these could ensure that NO rogue wired hardware could be easily planted on the local net. Of course, I realize that someone with skills could do some sort of man-in-the-middle hijacking of packets and obtain service or illicitly move company secrets off-site, but for IT departments such dealing with less secure data, but which need to keep rogue machines at bay, would these devices make sense? (This assumes that wireless is either forbidden, jammed, or just not being used at all...)

    But, will these Linux Jacks play a role in distributing and deprecating the expensive Cisco-type routers, firewalls, and switches? Not that Cisco hasn't already thought about and quietly stashed away a response plan, but isn't it inevitable that devices like these will begin to erode the market for the big, expensive companies which have a motive to push/sell large quantities of expensive iron?

    Seems to me, programmable, managable things like these, provided they have few exploitable pieces of code in them, could act as very intelligent, distributed ports, monitoring, reporting, and even honey-netting and more.

People in the automation world probably remember a few years ago how the PC-based "soft PLC" would reduce costs and replace all those proprietary, expensive traditional PLCs. Never happened and never will because PCs are too general purpose and inefficient. To this day all I've ever used software-based PLCs for is simulation.

    For those who are unaware, PLCs, or Programmable Logic Controllers, are esentially purpose-built embedded computer systems used to monitor and control industrial equipment. The bulk of them today are about as powerful as a 286 PC or even less and they cost as much as or more than a high-end PC. Despite that, the hardware and firmware/software in a PLC is designed from the ground up for deterministic, hard-real-time operation and I/O intensive applications. They also do not have processor fans, hard drives and other unreliable mechanical parts.

    That is why these tiny Linux machines are so interesting--even if they cannot do as much as a PC or are more expensive. They could be the beginning of a standard, truly open platform for embedded systems. If the processor unit can fit in an RJ45 jack, then in the future we could do away with racks of PLCs and make field equipment control itself. The stuff I can imagine is mind boggling to say the least.

  38. The picotux is actually smaller than the gumstix. by sytxr · · Score: 5, Funny

    The gumstix has a larger surface area, the gumstix has a larger average visual cross section when viewed from a random angle. German shipping services like to define the size of a packet, for the purpose of determining fees, as the sum of of its dimensions.

    Which is smaller - a gumstix or a sheet of paper ? If you say it's the gumstix, then the picotux is smaller.

    Otherwise it does not make sense! The german postal service says the picotux is smaller, so the picotux is smaller; but what do shipping fees in Germany, which are paid in Euro, have to do with the size of the gumstix in comparison to the picotux ? And why am I comparing it to mice which are mammals which are rodents of the genus Mus as computer input devices ? It does not make sense.
    Therefore you must admit the picotux is smaller.

    This is *exactly* what I've been thinking of for a weather station. Add the processor to the sensor, place one on the anemometer at 10m, another on the temp sensor at 10m, but have it tightly networked to the 2m temp/humidity sensor. Presto! intelligent heat flux calculations. Tie the 10m anemometry to the 2m wind speed, voila`, 3d wind data.

    well, that may be true, but until the mesh topology network technology becomes more popular and more advanced, we're still at the mercy of the network. in a large network of small processing cores, the importance of network integrity is significantly greater than in smaller networks, especially if redundant systems share a common network. if a switch dies, the potential for stranded data is larger if there are more nodes connected through that switch.

    this all begs the question of when this technology will be applied to neural networks and artificial intelligence.

    I guess one could hook up an ADC and/or a DAC with some kind of serial interface, perhaps I2C, to some of the 5 GPIO lines. However, as the unit stands, it seems to be most suitable for a "RS232-to-Ethernet" converter application, to easily add networking to equipment with the simpler interface.

    Although 5 GPIO lines and an RS232-style serial connection does allow for connecting other interesting kit, what would have been really nice here, would have been a larger number of such general digital IO lines, and perhaps some additional peripherals, such as a timer/counter, ADC, and DAC.
