TheJamesHimself got a 106 on his final

[home]    [projects]    [stupid]    [music]

so we have an old linksys router (befsr41/befsr11/befsru31) that has a problem of overheating and killing the internet connection. so i'm going to put a fan on it.

 to take it apart - rip at it until you break everything into pieces... while you're at it, grab a fan:

now that you've alleviated yourself of the stress of not knowing how to disassemble this piece of crap (and not being able to look it up on the interweb), cut a big hole out of the lid and mount the fan using a couple of screws:

warning - math/physics: because the router is designed for a 1amp load and the fan is .25a, you'll need to put a resistor in parallel to divide the current. step one - figure out the resistance of the fan:

mine was 5.23 Mohms. using my very limited knowledge of current dividers i came up a value of 1.75 Mohms for my resistor (if this is way off email me). i soldered a few resistors in series to get close to this value, then figured out where on the router's pcb i can steal my power from (that's bottom side closest to the power plug):

solered my leads off the board then wired everything up according to my diagram above:

in it's glory:

quality.
