Battery Powered Solder Fume Extractor

thingiverse

This is a remix of the great battery-powered solder fume extractor by Malectrics. It almost shares the electric schematics from it, so check the original page for instructions. #### Changes * Added an hole on the side for a better switch * Added a support for the USB charged PCB to lay on - no need to glue styrofoam anymore and more room for wire organizing * Added two tiny holes just over the battery charge monitor to guide the status LEDs light from the charger to the case. Glue a small piece of transparents nylon wire on these LEDs and on the holes (1mm fishing wire is perfect for this) * Changed the hole for the FAN wires to an U-shaped and moved it on the top - this way you can slide the wire on it saving the original JST plug coming from the fan. * Added the embossed, logo of my Youtube Channel on the bottom right corner Fusion 360 archive file is provided to you to change dimensions, to remove my R3 logo, etc. The switch is crimped for easiness, but you can solder too if you prefer (or you want to save some bucks) You may want to add a 1N4007 in anti-parallel to the step up converter out for better protection against reverse emf currents. If your fan is not _state-of-the-art_ (read: cheap, inductive crap) you _could_ blow the MOSFET inside the converer without it. #### Shopping List (I earn some pennies while buying from the links below.
