Solder fume extractor

Unleaded solder obviously isn’t made of rosewater and unicorn kisses though, so whatever you’re using when you’re sticking electronic components on to PCBs, you’ll need some sort of fume extraction method. Prolific maker Arnov Sharma has come up with this fume extractor, built on a Raspberry Pi Pico and assembled out of 3D printed parts that he’s designed himself. 

At the core of this device is a repurposed CPU fan, a Raspberry Pi Pico, and a custom PCB driver board. Arnov also designed his own PCB to host the switches, and another one to hold the LEDs in the light – because you need good lighting when you’re soldering components together. The body is all made from 3D printed PLA, including the diffuser that sits over the LEDs, and there’s room for a replaceable filter for the fumes, so you’re actually removing toxins from the air and not just cycling air around.
