I'm thinking of making a DIY fume-extractor for soldering electronic components to the circuit board. I like the idea of being able to vary the fan speed. This would allow me to set the speed for best draw of fumes into the carbon-activated filter chamber.
What are the primary electrical considerations to properly match a potentiometer [/QUOTE][/QUOTE][/QUOTE] to a small fan ?
Thanks in advance !
