80 mm Fan Solder Fume Extractor

This was made using a TP4056, a toggle switch, a boost convertor, some activated carbon, and a high static pressure 80x25 mm 12V fan. The magnets I used were 5x2mm. It gets enough airflow to suck in fumes from about an inch or two away, which is acceptable for a battery powered mobile tool to complement my Pinecil.
