Window-mounted solder fume extractor (not just for RVs!)

Step 10 Plug in power and start soldering!

Now plug in your power supply (or 12V lighter plug if you're in an RV; I used an old cell phone charger cable from the thrift shop) and you're ready to go. Adjust the hood so that it is as close as possible to where you're soldering and make sure that it's capturing the fumes OK. Make the hood bigger if you need to.
