    I was reading the book "The art of designing embedded systems" and came across the phrase "Firmware is the most expensive thing in the universe". It's true, considering Firmware has no mass. (about $25-$50 per line of code)

    The book also mentions that NASA paid $1000 per statement for the space shuttle firmware, and that Firmware accounts for 40% of the cost of a fighter jet.

    I'm enjoying the book.

    Unless you consider the mass of the electrons on the floating gates of the the flash memory array.... :D But the $$$/mass ratio would be huge anyway...
    I am currently playing around with some free firmware (PIC based HTTP server) for the ENC28J60 ethernet IC from Microchip..... It is really cool to be able to control a LED from Internet explorer for such little effort using light weight firmware you can download for free. :)

    Call your cable provider. In Toronto Rogers was more than happy to replace their old modem for a new one.

    As for the router, got an old PC laying around? This is awesome software and it's free.

    Really I have nothing but praise for it. Now when project #3 comes out it will tie into this.;)

    Firmware is actually the cheeeepest thing in the universe. If we didn't have firmware then where would windoze start when it booted up. We pay a lot for windoze and nothing for the firmware that makes it runable.

    When it comes to no mass, I guess that all knowledge has no mass and therefore all knowledge has infinite value.

    P.S.vGrim, are you not an engineer?

    Right now it is just on the LAN side of the router since my ISP doesn't allow me to run a Web server. Not to mention that I'm not sure how robust the TCP stack is yet and I'm just playing around with it right now...
    Any ideas of something geekier than an HTML controlled LED? The more pointless the function the better. :D
    BTW, I'm not an engineer... ;)

    An old friend of mine, who I've not seen for many years, used to write software for military missiles - for a large UK defence contractor.

    His wife used to work in Public Relations for the same company, one of her jobs was providing prostitutes for visiting dignitaries at posh dinners - she was always upset that THEY got a dress allowances, but SHE didn't!.

    I like it.... Then it would be platform independant. The Monica/Clinton one is the best IMHO.

    Try FreeCycling...it's hard to get something before it's gone...but it'll be free if you do get it...usually you have to go pick it up tho.

    Most major areas have a FreeCycle thingy, just Google around a bit. Some counties might have one too.

    Best of luck!
