  3. StrongARM router/firewall/server by [Xorian] · · Score: 1 · on Build Your Own StrongARM Linux Computer

    [Moderators, prepare your offtopic flags]

    I've been trying to figure out how to build a silent (read: convection cooled) Linux firewall/router to serve my cable modem connection to my other machines. I'd like to do it with a StrongARM part, but I can't seem to find a solution with a reasonable price (sub $500 total).

    I've looked at the Chalice CATS, which could definitely do the job, but is more than $500 just for the board. LART looks pretty cool, but seems to have support for only one ethernet adapter at this time (and I have no idea how much it would actually cost). The NetWinder is also very cool, but it starts at around $1400 (and I've heard that they are not exactly silent). I've seen some info on machines from Acorn which might fit the bill, but I haven't been able to get their website to load.

    Does anybody out there know of a low-cost StrongARM device which can run Linux and can support an IDE drive and two ethernet adapters?

    Yes, I've looked at the fixed purpose firrewall boxes that do this, but I work for a large company with a constantly in-flux Intranet tunneling strategy, so I want enough control of my firewall to make sure I can keep up with the protocol du jour. I've also considered doing an insane i-opener hack (one USB ethernet adapter, one parallel port ethernet adapter), although I might as well just pick up a cheap box with a socket 7 motherboard and slap a Winchip in there myself to get the low power consumption. I'd have to take some other steps to quiet such a box, but it may be the best solution in my price range. Still, I think a StongARM solution would be much cooler.

  4. Chalice CATS by Anonymous Coward · · Score: 4 · on Build Your Own StrongARM Linux Computer


    There's another, perhaps more accessible ARM based Unix computer out there for experimenters.

    It's call the Chalice CATS, a ATX-form factor board, with a StrongARM processor (at 233 MHz,
    IIRC), and most of the other features of a relatively modern PC (3 PCI/4 ISA, parallel,
    serial, USB ports, SDRAM DIMM memory, UDMA/33 IDE port).

    It ships with NetBSD, but if there has been some porting effort for Linux.

    Have a look-see:

  5. photovoltaics, power consumption by Anonymous Coward · · Score: 0 · on Wind-Up Notebook Computers
    Since it seems we have a few geeks (or perhaps not geeks; I'm just guessing from the posts I read ;) around who are sufficiently knowledgable regarding this sort of thing, anyone care to guess at the power consumption of the board shown at http://www.chaltech.com/products.html? I want to have a portable machine put together by the end of this coming summer that runs entirely off photovoltaic power, and I've been looking for parts for some time now. I can probably get >10 watts in full light with all the film/panels exposed to light, and perhaps 1 watt with dim light, but I'll of course have a storage battery so it should all even out.

    Any suggestions for parts? Here's what I'm looking for:

    • CPU/Mobo - needs to be minimal power consumption so it can run idle even with very little light and periods of darkness. I'm currently planning on using strongarm, but I haven't decided on any particular board.
    • Storage device - large but low power consumption; speed isn't much of an issue. An eeprom-based storage device might be the best, but I really don't know enough to decide yet.
    • Display - know of any good non-backlit lcds? ...any at all? :) Power consumption isn't a big issue, since the battery can supply power when the display is active, but I do want to keep it as low as possible.
    • Network interface - some sort of wireless ethernet for short range, plus something like freewave's wireless terminal adapter for long range (it uses a bit of power, but I think I could handle it...although I might change my mind if I see the price :).
    • Photovoltaic power supply - I'm open to suggestions, but Jade Mountain's look nice...


    I've been trying to get this thing put together for over a year now, and I'm still in the planning stages (although I have found some nice places to get hardware), so I'd really appreciate any suggestions/help I can get. While I'll check for replies here, it's probably easier to just email me if you want to discuss the project, since no one looks at old slashdot articles anyway after a few days... ;)
