The NW is velcro'ed to the inner side (the one on my thigh) and touches no other side, thus any pressures on the case go around the NW and since the super-case is firmly attached to myself, accelerations are reduced too. The idea was: "How do I maximize hardware survival should I fall down onto the case". >> Minus: runs very hot internally (typ: 50deg C) and is *not* hardened like > >It does- it has a lot of PC type peripherals packed into a very small >area, and not all of them can be powered down when not in use. > >> SO-DIMM RAM is custom...some internal specs are available, but it's (IIRC) >> a 10-layer SMD board..definitely *non*-trivial to hack. > >I've spent months hacking it, and am still working on it- though I am >getting paid for it ;) There is a daughter card which in the standard >machine has the 10/100 ethernet chip, the serial port driver, and some <snip> >could potentially reprogram the FPGA to do things like image processing if >that was more useful to you. We originally planned to use a DSP, but the I've always thought that a NW with a DSP daughtercard (think Analog's SHARC) with mucho I/O could become a killer lab computer or industrial process controller...or wearcomp. Unfortunately, it seems Rebel.com is not going at all in this market. >--------------- Linux- the choice of a GNU generation. -------------- >: Alex Holden (M1CJD)- Caver, Programmer, Land Rover nut, Radio Ham : >-------------------- http://www.linuxhacker.org/ -------------------- -- Eric LaForest Nascent Linux Something -www.netwinder.org/~elafo/- #define Hacker !(Cracker) //FYI: http://www.tuxedo.org/~esr/jargon Breaking into computers does not make one a hacker, for the same reasons that hotwiring cars does not make one a mechanic... paraphr. from ESR -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org
