Intro: Fume Extractor Powered by Bench Top Power Supply
Hi there, in this instructable I am gonna show how to make a simple fume extractor that can be powered from a benchtop power supply.
here is the parts list
2x 12volt fan
2x bullet connector
leftover metal mesh
and some wire
Step 1: Prepping the Case
I drilled a hole for the fans and screws. then I placed metal mesh and placed screws on it. After I placed the mesh, fan blades made a noise because of the contact with the mesh. Later, I soldered two 12v fans in parallel on a small piece of perfboard.
Step 2: Assembly
I placed filters, closed the box and soldered two wires to the bullet connectors. Finally I attached the bullet connectors to the stable 12v aux ports to my power supply.
