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
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 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
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
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!
It is quite refreshing, and it is a great utilization of old recycles.
