I've got active cooling!!!

    I am working on a project for my highschool tech expo. I decided to go with something in the networking category preferably wireless. Upon deciding to tackle something in this category I knew I had to modify a wireless ap or router, and prove that the schools microwave was sooo outdated and that my little 80$ wrt54gs ver. 2 could kick their expensive POS's ass. Not only going further than their link but pushing the speed to unbearable means. So far I've only got to the active cooling stages via the use of two fans per router one under the unit (exhaust fan), and one inside the upper segment of the unit (intake fan) effectively creating some airflow (now it really sounds like a nix box). I used two 8$ hard drive coolers and removed the fans (hdd coolers had 2 fans each). I then went about wiring them up directly to the female end of the barrel plug. After this I mad some spacers out of heatshrink, then hot-glued the antenna cable down, and finally mounted the fans via screws and I will soon paint the Router a mettallic silver w/ some bad ass graphics.

    I have the alchemy pre7a firmware and it kicks major ass, well at least so far. I haven't tried to connect the two routers via wds yet. The next step in my little project is to make two directional antennas with some primestar sattelite dishes. I will be using two aluminum-welded soup cans for the feed can w/ chassis mount n-connectors solder about a quarter wavelength onto the connector. I'm totally stoke and hopefully I'll win either an iPod or Palm outa this whole excursion. Well I just thought i'd let everyone know and hopefully you can give me some suggestions.

    I also have a micro-atx machine in my 99 f150 w/ a lilliput 7" vga lcd, So this will hopefully turn my router into an entirely mobile access point which could eventually be connected to the internet via at&t or verizon sattelite!

    I have pics but i can't post for some reason... anyone wanna host for me?

    could you be more specific on how or were the power supply for the hdd fans are coming from

    i also have active cooling on my wrt54gs
    and i have some tips for you
    dont increase the output too much because you will get a degrading dirty signal around 56mw seems to be topps per concensus.

    i used an old pentium pro heatsink fan which just perfectly fit into the holes in the top of the router.
    then since i dont use it on high power all the time i wired in a small toggle switch between the antenna and the reset button which i colored linksys blue.
    the fan seems to do its job because i have no heat at 50mw and when i turn it down to 1mw i can switch the fan off.


    it is undetectable from the top and sides (except for small fan hummm) but in the rear you can see my switch.


    p.s. i can host your pics and i will be getting mine up as soon as i do the serial port mod.

    hit me back and i will figure out how to host them (i have a dedicated webserver but i am not near it and on dialup


    addressing the above post. the power connector that runs the unit has enough power for a small fan so i hardwired it into the bottom of the pc board so that i didnt have to mess with it again.

    not really as the connections are not that small all you need is a medium to small soldering iron and some extra wire (small) if the fan doesnt already have enough

    i have to steal me fiance's camera and i will get pics up...
