Tell me what you want it to do and i'll draw you a schem.

 

i would like it to at least ctrl three or four fan speeds because i am thinking of building a protype fanbus see http://forums.bit-tech.net/showthread.php?s=&threadid=28048

also i just want to see how to make a fanbus maybe cheaper than buying and more fun building own stuff.

 

Well i'm guessing you want minimal circuitry then:






The stuff that will go in the keyboard is on the left, the Stuff in the PC is on the right.


50Ohm Pots should do the trick (AT A HIGH WATTAGE)

 

thanks mate - that s great

 

no problem
