Build electric boat and solar boat yourself - construction manual for children: yourself

Packaging materials can be used to build fast electric boats and solar boats. By dealing with different materials and the small electronic work, children not only learn what can be made out of packaging, but also train their technical understanding. If a A solar catamaran made of styrofoam, a solar boat from an empty fish tank or a propeller boat made of PET bottles: On this page we present detailed construction manuals for three different boats, which are operated with solar or battery.

For the following construction instructions we have used the electronic and solar components from the learning package "Adventure Electric and Solar Boats" by Franzis Verlag. Most building steps can be done by children from 8 years old. Since the connection of the solar cell or the batteries is a little tricky, parents should take over this task for the children.

  • Styrofoam
  • 1 x large roll of duct tape
  • 2 x chopsticks or 4 x long shashlik skewers
  • 1 x black marker
  • 1 x wide cutter knife
  • sandpaper
  • tongs

From the electronics building book:

  • 1 x solar cell
  • 1 x solar engine
  • 1 x air or ship propeller

Cut boat from Styrofoam

Build catamaran from Styrofoam

In the first step, the Boat parts for the catamaran cut out, To do this, draw two long rectangles on the styrofoam, whose front tip ends in a triangle. For the middle bridge a third piece is cut to size. This should be wide enough that the roll of adhesive tape fits on it and the two long boat parts have a distance of several centimeters. Match the styrofoam pieces, prick them one long chopstick in the middle from above into the two hullsto fix the middle piece. Knock off the protruding chopsticks with pliers. As an alternative to the chopsticks, there are also two long shashlik skewers per side.

Attach solar engine and solar cell

Now a piece of Styrofoam is cut so that it can be pushed into the roll of adhesive tape. Now cut a piece of tape with the cutter and push it over the solar engine so that the pin looks out. Now fix the engine on the polystyrene bar, as you can see on the pictures.

In the next step, a wide piece of tape is folded inwards into a roll and pasted under the solar cell. Alternatively, double-sided adhesive tape can be used. After that will the solar cell in the middle of the roll of tape pressed. The red and black cable should point in the direction of the ship's engine.

Now put the ship's propeller on the pinn and test whether it does not hit the styrofoam or the adhesive tape roll when turning.

Done is the self-built solar boat

The next step will be broad Adhesive tape folded again and glued to the middle styrofoam bar of the solar boat and the roll of tape firmly pressed. For a better grip you fix this with a strong tape on the boat. Alternatively, it can also be fixed with a special polystyrene adhesive.

Last will be the red one Cable of the solar cell with the black cable of the electric motor and the black cable of the solar cell with the red of the engine connected, So that the cables do not get into the ship's propeller, they are tied together with a rubber band and fastened in the reel.

Now the solar catamaran is ready and can be put to test run in the sun.

Solar boat from fish tin

Build electric boat and solar boat yourself - construction manual for children: boat

Material for solar boat

This boat is made in about half an hour from a rinsed and cleaned fish can. If you want to build this solar boat yourself, you need the following Materials:

  • 1 x empty fish tin
  • adhesive film
  • rubber band
  • Possibly. double-sided adhesive tape

From the electronics building book:

  • 1 x long additional axle
  • 1 x reducer connector
  • 1 x small propeller
  • solar engine
  • solar cell
  • Possibly. Crocodile clips with cable

preparation

First, the empty fish bowl must be completely rinsed and cleaned of grease. It should be noted that the small opener does not come loose from the metal lid. Once the can has dried, the solar boat can start building. Beware of sharp edges of the lid!

Build ship deck from fish tin

In the first step, the lid is completely pulled out of the box and bent as in the first picture: Gently bend the end down with the opener and slowly push it outward, Here is a sure instinct so that he does not break off. The other end is bent diagonally upwards. Now you put the lid into the can and correct the shape of the ship's deck if necessary.

Build motor and drive for solar boat

Self-built solar boat

Next you put the Solar engine on the folded openerso that the pin points out through the opening and sticks it with adhesive tape. The connector is placed on the pin and connected to the axle and the small propeller.

To fix the solar cell, one folds a strip of adhesive film into a roll and sticks the solar cell onto the bent end of the cover. Alternatively, double-sided adhesive tape is also suitable.

Now put the lid to the sample into the can and correct - if necessary - the position of solar cell and drive. The propeller should touch the ground.

Remove the cover and push the cables under it. With the help of Crocodile clips connect the red cable of the solar cell with the black cable of the motor and vice versa. The protruding cables are tied together with a rubber band or a cable tie under the lid.

Finally, fix the lid with a folded, wide roll of adhesive film or double-sided adhesive tape in the fish tin. The terminals and bundled cables are located in the middle and front part of the solar boat.

Tips for swimming test for the solar boat: It is important that the weight evenly distributed in the fish bowl, so that the boat has no list. To test it should be placed in a water-filled sink or in the bathtub. If it is too heavy at the front, the clamps are pushed further into the middle or the solar cell is moved backwards a bit.

Construction manual for a propeller boat made of PET bottles

  • Propeller or large propeller
  • battery holder
  • Crocodile clips with cable
  • solar engine
  • solar cell

Build center bridge

At the beginning you cut with a broad one Cutter made of styrofoam the center bar, In the process, two recesses are cut in the lower part, to which the bottles are attached later. The upper end of the polystyrene gets a round recess, in which the engine is set. For clean edges, sand the bridge with sandpaper. Then the motor is fixed with the pin outwards with strong adhesive tape in the recess.

Assemble propeller boat

In the next step, the propeller boat is assembled. For this one drills with scissors small hole across the central pier above the recesses for the PET bottles and pushes through a long cable tie. Now attach the bottles to the styrofoam piece with the second cable tiewithout tightening it. So that the bottles do not collide at the rear end, cut a narrow block of Styrofoam and push it in between. In addition, the solar cell or the battery holder so a better grip. For greater stability, both bottles are fixed with adhesive tapeas can be seen in the picture on the right. Now put the propeller on the pin of the solar engine. It must not grind on the center bar when turning. If the distances are right, the cable ties are tightened and protruding ends are clicked off.
