Soldering Fumes Fan W/ Bendy Arm and Smoke Sensor

This is a Soldering Fan to remove harmful fumes created when soldering. This fan includes and adjustable desk mounted arm, a dial for a fan speed, a smoke sensor to alert users of high dangerous smoke levels, special solder filers, and a durable 3D Printed Encasement. This is a great, fairly simple project for go getters and regular solder's ready to build their own soldering fan.

ESP-32 Dev Module, Wires, Ardunio Smoke sensor, switch, LED, 9 volt battery, battery housing

Step 1: 3D Print Your Pieces

3D print with the files below. You will need one hexagon shaped encasement, one of the square shaped fan encasments, and two of the panels.(one for the front, one for the back) I used matte charcoal PLA filament with default printer settings.

Step 2:

Using a drill or a sharp hand saw cut a slot for the fan wires to pass through the encasement. Then install the fan in the encasement. Make sure to install the fan facing the correct direction so it pulls smoke through the side you want.

Step 3:

Using the dial provided with the fan, break open the compartment it comes in and drill a hole inside of the hexagon encasement. I then pushed the dial into place. I also carefully removed the sticker that was on the original housing and placed it as desired. (This step is optional for esthetics)

Step 4:

Carefully place your fan and the housing in the middle of the encasement and make needed connections. This part may take some fandagaling to get the cords in the spaces around the fan.

Step 5:

Then make a small cutout for the power cable to fit through. This will make more sense later after we install the back plate.

Step 6:

Upload the code provided below upload it to your ESP-32 Dev Module, You may need to play with the sensitivity number depending on your smoke sensor. I have it set at 650 and it works great. Follow the connections shown in the images, if you need to you can refer to the code for further pin outs and correct connections.

Step 7:

Drill a small hole inside of the fan housing on the opposite side of your dial, you will also want to drill a hole for your LED on the outside of the hexagon encasement. Glue LED then slip the wires through fan housing, make connections and glue your sensor to the center of the fan.

Step 8:

Drill a hole for your switch and install where desired. After having everything installed you should have something that looks like this.

Step 9:

On the front of the fan, the side that sucks air in, outline and cut a hole on your faceplate for the battery housing. The housing should sit on the same side as the ESP-32 Dev module and your wiring. Test fit your pieces, glue/screw as needed.
