This PIC controlled fanbus allows to control the speed of 6 fans with PWM.
It uses 4 7segment led displays wich are multiplexed and the PWM is generated in software.
your zip file is incorrect. It contains 1 file called "Fanbus[1]" this needs to be extracted and renamed as "Fanbus[1].zip" and then re-unzipped...OR uploaded again correctly.
Other than that, it's a nice looking and well thought out board design (I am at work so I didnt look into the schematics or code).
