A 12 volt fan made from scrap found in Techshop in Chandler, AZ!!
A cardboard tube
Old ventilation fan
A glue gun
Step 1: Step 1
Find a working vent fan from any broken down electronics
Figure out which of the 2/3 wires in the back are the positive and negative ends.
Step 2: Step 2
Attach 2 sticks, or more if needed, on the sides of the fan using a glue gun.
These sticks will help make the fan stand upright.
Step 3: Step 3
Glue together the end of the stick to form a 'V' that would go inside the cardboard tube
Step 4: Step 4
Find a cardboard tube big enough that will support the fan to stand upright.
Put in the 'V' end of the stick inside of the cardboard tube and apply glue inside to keep it from moving around.
Step 5: Step 5
Find an old adapter that would work on the fan. In my case, I found a fan that runs on 12 volts, and luckily an adapter that would work on it.
Step 6: Step 6
Cut off the end of the adapter and find which of the wires is positive and negative.
Attach the positive end of the adapter to the positive end of the fan. Do the same for the negative. (ignore the yellow wire :P )
Tape the wires together and you're done!
