This is a solder suction device for soldering. You need:1x toggle switch 12v1x step up converter1x USB cable to plus and minus1x 80mm fan8x pc Fan screwsI couldn't find any other fume extractors in the internet so I just created one.I used a step up converter to volt the 5v of the usb up to 12v, But I wouldn't set the volt higher, otherwise the fan would quickly break.
