@zadiac your Computer fan mixer, do you use a heating pad for heat and if so how do you temperature control it? I made one months ago with a portable usb fan thingy as per 1 video on YouTube and it was not strong enough to mix anything unless the beaker almost touches the magnet. Very keen on building the Comp Van setup?
I'ts a 120mm fan. The heating pad has a controller on the cable. I use strong neodymium magnets and the magnets are about 1mm from the top plate which is a cd case that I cut to fit. I'm working at the moment on a new one that will use a higher torque high speed dc motor with a speed controller.
I bought the heating pads on ebay and they're for heating reptile tanks. They don't get hot, just warm. Highest settings on the heating mat and the ejuice only gets to about 32degrees. That's fine with me.
