Fume Extractor

Be safe, protect your health, use Fume Extractor when soldering!

This is version number two of my previous Power Bank powered Fume extractor.
This time i am using 12V PSU and PWM control!
Inside is Xbox One 12V fan but it will fit probably other fans too.
If you have some fan which do not fit just edit attached Fusion 360 file.

You can use up to two carbon filter for better air filtration.
Just remove filter holders cut carbon filter to fit and place it inside.

You can control speed of fan and check RPM on OLED display.
When you are changing RPM with knob there is also some LED(Neopixel) animation to see level of PWM.

There is also fan check if it is really spinning and if not there is loud beeping and Error animation with LED and OLED display.

It is obvious that there is piezo buzzer inside as well:)

It is designed to stack more units together if you need more fans in the row, driver board(electronics box with OLED, knob, etc.) is separated and will fit to fans
