Because I have to work with solder wire so,I have to protect myself from smoke of it.
I use the simple rectifier 7812 to drive a big fan. You can see from video below.
It might not be able to protect my nose 100 % but at least I don't want to breathe the solder wire directly.
If there're more budget,I'll buy the smoke sucker.
Here is my simple rectifire 7805 and 7812 for 5Vdc and 12Vdc.
