Today i’ll show you how to construct my design of a PVC mini Submarine
A submarine is a type of boat that instead of floating is supposed to sink, but not like a rock to the bottom it must have neutral buoyancy. This different design isn’t like the normal box shape design well it’s in the shape of the letter “ i “. So our thought process when we built this was one end would be longer than the other this is for Air will make it float in the longer end. And the smaller end would contain some kind of weight like sand or water. The propeller facing up on the air end would force the leveling out of the sub. Then the propeller facing outward attached to the weight end to well propel the sub, and to steer we have one last propeller facing to the right attached to the spine of the sub.

Materials / Equipment you will need

- Toilet Wax Ring - For the wax you need

- 3 Propeller

- Plastic cup

- Gloves

- Eye protection

- PVC cutter

- Soldering iron

- Aluminium Solder

- 10ft of 1/2in PVC

- 3 switches

- 2 Zip ties

- 2 ½ in t fittings

- 4 1/2in socket caps (or 2 if you want to use water as your weight)

- 40in of wire (with 4 different colors rapped around white wires)

- 6 feet of wire (with 2 colors (Red & Black (Positive and Negative)))

- Electrical tape

- OSEPP Motor x3

- Wire strippers

- 35 mm film canisters x3

- Computer Charger

Step 1: Making Your Moters

Picture of Making Your Moters

The first thing you'll need to do is gather the following materials:

- Toilet Wax Ring

- The 3 Propellers

- Gloves

- Soldering iron

- Solder

- Power source

- The 3 OSEPP Motors

- 3, 2 foot pieces of wire (2 mini wires inside)

- Eye protection

- 3, 35 millimeter Film canister

- And wire strippers

- Extra set of hands (someone helping you)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We'll start by taking Putting on gloves & eye protection (Safety First)

Then open the top of the Wax Ring, and role out wax with your hands. 3 the size of a nickle, and 3 the size of a dime.

Take off cap & poke about a 1 mm hole in the bottom of each of the Film canisters (Roughly Centered)

Plug in your Soldering iron - DO NOT TOUCH (The hot end)

Take one of your 2 foot pieces of wire, and taking your wire strippers strip one end of the piece of wire 1 to 1.5 inches down. Exposing 2 wires (color doesn't matter but we have Red & Black)

Using the strippers strip the Red and Black wires to the copper wire about a forth to a half an inch

Have some one hold the Red wire to the positive

Pick up the Soldering iron and the solder the RED and BLACK wire to there respective sides

When you wires are soldered on set aside

Take a wax ball (Nickel size) and Place / squish the wax in the bottom of the film canister. Don't worry about the hole for now. We do the wax to water seal the motors.

Now with the tip facing down place the motor into the some what filled film canister and stick the tip through the hole we made earlier

Now in the cap of the Canister poke a hole about the same size (maybe a bit bigger) as we did at the bottom.

Now add the dime size wax ball to the top of you motor

Run the end of the wire ( Not the one connected to the motor) through the hole in the cap

Press the cap on. If the cap doesn't fit remove some wax

Do this process with the last 2 motors

Then place on your Propellers

Step 2: Making the Frame

Picture of Making the Frame

Materials list:

- Pvc Cutter

- 10 ft. Pvc

- TWO 2 inch T shaped fittings

- 2 PVC Caps

- Electrical tape

Next, it’s time to make the frame. Start by grabbing your PVC and cutting as follows:

Cut list: -

- Cut a 18 inch piece out of your 10 ft PVC pipe

- Cut FOUR 5in. pieces of remaining PVC pipe

Now to put it together:

- Tape electrical tape on the 2 ends of the 18 in. spine. Connect the T fitting to each of the ends of the 18 inch piece. As seen in the picture. Some force is needed

- Then, connect the 4 inch pieces on each of the ends of the T fittings.

- After that, put the caps on one of the ends of the 4 inch pieces. - Lastly, put the T fittings with caps on that end with the one you want air in.

Step 3: Where to Put Your Motors

Picture of Where to Put Your Motors

Materials:

- 2 zip ties

- Electrical tape

This step is a short but crustal one:

In the 3rd picture the motor is facing away from the spine. Do that but on the side with the weight, and make sure that the propeller isn't going to hit the PVC in anyway.

- Place the motor on the T on the weighted end. Take the zip ties and zip them around the motor to keep it in place (not diagonally; strait), but to make sure it isn't going anywhere wrap Electrical tape around it a few times.

Now in the 2nd picture the propeller is facing to the left and is located near the weight side and is attached to the spine with Electrical tape.

- Place the motor on the spine facing left near the last one, using Electrical tape, tape it in an X fashion.

And lastly the 1st picture it's facing up on the "air" side, so it can level out the sub

- Place the motor on the T on the air side facing Up, and using Electrical tape, tape it in an X fashion.

Step 4: Attaching Your Motors to Your Main Wire

Picture of Attaching Your Motors to Your Main Wire

Materals:

- Wire strippers

- Soldering iron

- Aluminium Solder

- Main wire (4 colors)

- Electrical tape

- 3 switches

- Power source

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Plug in Soldering iron

-Take 2 wires of the same colors and and connect them to the 2 prongs coming out of the motor.

- Once it is connected then solder and tape the switch together

- Place the soldering iron over the point where the wire and the motor touch.

- Touch solder to iron and wait for it to melt

- Once completely covered in solder remove iron and let cool (and since the aluminum is used for soldering electricity can pass through it so DON’T CROSS WIRE (2 different wires touching) it will not work.

- Cover in electrical tape.

Step 5: Making Your Switches / Attaching Your Switches to the Motors

Picture of Making Your Switches / Attaching Your Switches to the Motors

Materials list:

- Wire strippers

- Soldering iron

- Aluminium Solder

- 3 1 foot of wire (4 colors)

- Electrical tape

- Power source

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Plug in Soldering iron

- Take wires and strip 1inch of the outer layer of the wire.

- Then take motors and take wire of one solid color and one striped (the white that was wrapped around the color) with the same color line running down it and wrap the wire around the connection point and once it is secure (So Color let’s say green, put the green next to the Green stripped)

- Place the soldering iron over the point where the wire and the motor touch.

- Touch solder to iron and wait for it to melt

- Once completely covered in solder remove iron and let cool (and since the aluminum is used for soldering electricity can pass through it so DON’T CROSS WIRE (2 different wires touching) it will not work)

- Rap the connection in electrical tape.

Step 6: Getting Power to Your Motors

Picture of Getting Power to Your Motors

Materials:

- Computer Charger

- Your Switches

- Power source

- Your Remaining wires

- Scissors / Wire strippers

- Soldering iron

- Aluminium solder

- Electoral Tape

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After placing your motors, you are going to want to have them work. You have all of your wires connected and soldered onto the switch.

- Now you are going to connect the computer battery (Charger) to the switches.

-The way that this works is when the battery is plugged in, it will give power to the switches, and the switches are connected to the motors making them move.

-Your switches should already be connected to the motors, connecting the power involves using the leftover wire.

-Take the remaining wires and lay them out. They should be the same color, one with stripes and one with solids.

-Take the computer battery and cut off the end of the plug that goes into the computer. The battery box should still have two wires on either side.

-Be careful, the battery should not be plugged in. Working with live wires can be deadly.

-Take the wire strippers and strip off the insulation like you did earlier with your switch wires.

-The inside of the insulation will look different.

- You should see two silver wires and a long piece of protective strand things.

-You can cut off the long strand things off.

- Separate the silver wires.

-Take the leftover wires from your switches

-Tie the striped wires to the dark grey wire on the battery

-Now tie the solid wires onto the exposed silver wires attached to the computer battery

- Plug in solder

- Solder the wires together then cover in electrical tape
