extractor

Every electronic lab needs a fumes extractor, so as i don't intend to buy one for the lab i made one, all started when found a "fan blower" from a server system, since this fans are system specific i had to do some reverse engineering, started to open the fan case tho see what was inside, what i found was a very robust system, the fan itself is made from aluminium the board has a nice layout were the air flow cool the power components, as the motor is a brushless i expected to find a brushless controller on the board and also found a pic16f88, the BLDC is a ML4425 with a few control pins that were connected to the pic, so the only thing i had to do was tho write my own control sw, the result was a very powerful fume extractor that work very nice.
