Step 1: Laying Everything Out
The list of supplies:
- Two Wire Hangers
- One Cream Cheese Container
- Two AAA Batteries
- One AAA Battery Holder (holds two batteries)
- One 1.5 - 3.0 Volt DC Motor
- One Rocker Switch
- One 25 Ohm Rheostat
- Assorted Wires
The list of tools:
- Glue Gun and Glue Sticks
- Exacto knife
- Soldering Iron and stand
- Wire Cutters
- Needle Nose Pliers
Step 2: Building the Base
Once you've cleaned out your container take off the lid and cut three holes in it. The one in the center is for the DC motor. The second largest hole (right) is for the Rocker Switch. You'll then cut a small hole for the Rheostat. Make sure you get a tiny slit in the lid to secure that rheostat.
Don't be worried about lining up the holes. As long as you have the motor in the center you can mess the rest up. Also, on the top of the cream cheese lid (where the label is) you might see a circle imprinted. That circle happens to be the right size for the motor.
Lastly, if you cut the hole to big the motor will slide right through. Cut the hole only big enough so the motor will fit snuggly on the lid. Use the inner diameter of the casing and not the outer diameter as your guide.
Step 3: Putting It Together
Hint: The Rocker Switch should be easy to flip on and off while the device is on. In order to do that you'll want to position it sideways so that it is just as easy to do both operations. The photo should make this description more clear.
Step 4: It Needs More Power
You can see how I've wired the device in the picture I've provided. If for some reason yours doesn't work with the same wiring, which would be amazing, just change the wires around. Your most likely problem will be with the rheostat. Notice I only use two of the three leads from that device.
Once you've done this step have fun turning it on and off for a while. I know I did! Play with the rheostat to see how fast and how slow you can get the motor going. You'll notice that by turning the resistance all the way up you can actually stop the motor.
Alright, now stop doing that! You'll waste the batteries:P
Step 5: Happy Feet
What I did was to take apart two wire hangers and bend them into the shape I needed. Fortunately they already come premade in a fashion close to what I desired. I've lined up the pieces I took from the first hanger next to the second hanger so you can see where I got everything from. The feet are about four inches high.
Make three feet and use a leftover piece of the first hanger to use for the wiggler. You'll attach that last piece to the motor later.
Step 6: Attach the Feet
You'll want to use the glue gun to secure the feet. The feet should point out a bit. That's to make sure the wiggler doesn't swing out and hit them. Also, a wide base will be a bit more stable. Make sure you don't accidentally glue in the batteries. The only other rule I have here is to ensure that you can get to both the switch and the rheostat. Otherwise, have at it!
Step 7: Attach the Wiggler
Be aware that the glue from the glue gun isn't rock hard when its dry. This might cause it to bend a bit and the wiggler might hit your fingers the first time you turn it on. Don't worry, it doesn't hurt ... much! Just kidding.
Also, put a weight of some sort inside the lid. A small rock or some quarters might do. It's a little too light to stand still on its own. The store bought one used D cell batteries to overcome this. I used a rock. Go figure.
Now check out the movie to see it in action!
One last thing, and this is critical: The water wiggler is supposed to stand on the three legs in a body of water. I don't show that position very often, but that's how it works. Don't try to float it in the bird bath upside down. It might scare or injure the birds you want bathing in your bath.
I hope you enjoyed my first instructable!
