We have an Altoids tin, and a water bottle. What can we do with that? Why not make a fan? That is what I did. I utilized the curve of the water bottle to make the fan blades, and an old motor to spin it around.
I used the cap of the water bottle as the holder of the fan blades, and an Altoids tin to house the whole thing!
Intuitive eh? I just Mashed the two items up, to make one awesome device!
Step 1: Materials Needed
- Altoids Tin (Or other enclosure)
- Small Motor
- Voltage Source for your motor
- Water Bottle
- Hot Glue
- Hookup Wire
- Switch of any sort
- Electrical Tape
- Dremel Tool with metal saw attachment or some metal cutter
Step 2: Prepare the Water Bottle
Find your water bottle. Take your Dremel or cutting device, and cut off the WHOLE cap neck. As shown in the picture. The bottom flimsy piece of the cap, as well as the cap, you need all of that.
Just take your Dremel, and cut it off.
Once you have the cap off, you can start cutting out the pieces of the water bottle which will be the fan blades. Take your scissors, and cut a straight line on the rounded part of the bottle, until you reach the part where it is is not rounded anymore.
Once you have that cut, cut along the line where it is not rounded anymore. This sounds confusing, but the pictures should help you out.
Now cut the rounded part of the bottle in half, so you have two fan blades.
Step 3: Attach to the Cap
Now retrieve that cap neck you cut off earlier. Take the fan blade and try to fit it in between the cap, and the flimsy round piece of plastic. Make cuts accordingly to have it fit snugly in between the two.
Now grab your hot glue gun, and on the top and bottom of the fan blade, put a strip of hot glue to keep it in place as it is connected to the cap and the other piece of plastic.
Do this for both blades, so they are opposite each other and spaced evenly. Spin the cap around your fingers to make sure the fan blades stay in place. If they do, you are all set to start wiring and cuttin for the motor.
Step 4: Cut Tin for Motor
Take your Altoids Tin and motor, and make a hold in the top of the tin that fits with the motor.
Just trace it or something, but you want the motor to fit snugly inside of the tin.
Now on the front face of the tin, make a hole for the push-button switch.
Step 5: Attach Motor to Cap
Now it is time to attach the motor to the cap and fan blades.
Take your Dremel, or cutting device, and drill a hole into the top of the cap.
Now poke the top of the motor through that hole. Take your hot glue gun, and glue the two.
You should be all set with the cap and fan blades attached to the motor.
Step 6: Wiring
- We have the power source of 3 Volts
- The negative lead of the battery clip, is soldered to a piece of hookup wire which is soldered to one of the motor solder joints. The other lead of the battery clip, is soldered to one of the leads of the switch.
- For the other lead of the switch, take a piece of hookup wire, and solder it directly to the other motor solder joint.
- Look at pictures for more detail.
Step 7: Time to Cool Off!
Attach the battery, press the switch, and hold it in front of your face!
It is quite refreshing, and it is a great utilization of old recycles.
