Materials and tools: what you need to work

Most of the materials will be found at home or in the nearest stationery store. Here. base-setThis is useful for any type of machine:

• 📦 cardboard - it is better to take corrugated (from boxes) with a thickness of 3-5 mm. For parts that require rigidity, cardboard from packages of household appliances is suitable.
• ✂️ Scissors and stationery knife - for cardboard cutting. Children should be given scissors with rounded ends.
• 🎨 Clay. — PVA for the purpose of putting together large areas, hot-glue or "Moment." for strong connections.
• 📏 Line and pencil - to mark up the details. Convenient to use metal-lineTo cut it with a knife.
• 🔩 Paperclips, rubber bands, threads. - to create mobile mechanisms.
• 🎨 Paints, markers, colored paper - for decoration.

For advanced projects You may need to:

• 🔋 Batteries and wires If you add lights or engines.
• 🤖 Servo drives (e.g., SG90) for the automation of movements.
• 💡 LEDs - to create effects (robot eyes, indicators).
• 🔧 Plastic straws - for guide or trigger mechanisms.

⚠️ Attention: When working with a hot glue or stationery knife, always use gloves Make sure there are no small children around. Cut the cardboard on hard-surface (for example, on a wooden board) so as not to damage the table.

If you plan to do so power-drivenCheck the compatibility of the components in advance. For example, a servo drive SG90 strain-driven 4.8-6 V VSo, select the appropriate power supply or batteries.

Step-by-step instructions: how to make a shooting machine from cardboard

So let's start with the simplest version. paper-ball gun. This model is suitable for children from 6 years old (with the help of adults) and explains the principles of the spring mechanism.

Step 1: Preparation of details

Download and print. gun-piece (or draw it by hand from a photo). You'll need:

• 🔫 Gun body (2 details - right and left sides).
• 🎯 Gun (a rolled-up cardboard tube or plastic straw).
• 🔄 The trigger (with a rubber band attachment hole).
• 🔩 spring (Can be made from a cage or a spiral from a notebook).

Cut all the details along the contour, carefully cut the holes for the barrel and trigger. Use it for smooth cuts. metal-line And a stationery knife.

Step 2: Assembly of the hull

Then, put two halves of the body between them. Fix the barrel with additional strips of cardboard inside the case - this will give the structure a rigidity. You can use it for reliability. hot-glue or double-scotch.

Stick the trigger so that it moves freely up and down. Check that the hook does not get stuck - if necessary, polish the edges with sandpaper.

Step 3: Installation of the spring mechanism

Secure one end of the rubber band on the back of the barrel (for example, using a paper clip), and the second end stretch and fix on the trigger. When pressing the hook, the rubber band should be sharply reduced, pushing the "shell" out of the barrel.

For precision add sight It's made of cardboard or plastic straw. Also experiment with the length of the rubber band – the shorter it is, the stronger the “shot” will be.

⚠️ Attention: Do not point the gun in the face or eyes, even if it shoots soft balls. Use it for games. goggles (e.g. sports or construction).

To increase the range of the balloon, lubricate the inner surface of the barrel vaseline Or a soap solution, it will reduce friction.

Vending machine from cardboard: how to make a mechanism for issuing

The vending machine is a more complex project, but the result is worth the effort! Such a machine can be filled with candy, small toys or even coins (for exchange). We'll take the option out of lever-drivenwhich is triggered when the handle is turned.

Vending machine materials

You'll need:

• 📦 Cardboard box (for example, from shoes or cereal).
• 🔄 Plastic bottle (to create a spiral dispenser).
• 🔧 A wooden stick or pencil (for the axis of rotation).
• 🎨 Paints or self-adhesive paper for decor.
• 🔩 Paperclips or wire (for fastening the mechanism).

Assembling the spiral dispenser

1. Cut the middle part (cylinder) from the plastic bottle and cut it in a spiral to make a long tape 2-3 cm wide.

2. Roll the tape into a tight spiral and fasten it inside the box so that one end of the spiral is at the exit hole and the other at the place where the candy is loaded.

3. Attach to the spiral. lever (a) which will be turned when it is pressed. Use it for smooth rotation. plastic-cap from bottles as bearings.

Issue mechanism

When you turn the lever, the spiral scrolls and the candy (or other small items) moves to the outlet. To the machine gives out one candy, make divider It's made of cardboard inside the spiral.

For design You can:

• 🎨 Paint the box under well-known brands (for example, Coca-Cola or Snickers).
• 💡 Add the LED lighting on the batteries.
• 🔊 Stick a button with a sound effect (for example, the entry "Thank you for buying!").

How to make a machine with a coin receiver?

For a coin receiver, cut a slit in the top of the box and install an incline plane of cardboard inside. The coins will roll into the tray and their weight can be used to trigger the mechanism (e.g., through a counterweight lever).

Automatic robot made of cardboard: moving parts and decor

If you want to create a static model, robot with movable arms, head or legsYou'll need it. joints and traction from threads or rubber bands. This project is perfect for a school exhibition or competition.

Articulation of hinges

For joints, you can use:

• 📎 Paperclips - unbend them and insert them into the holes in the cardboard.
• 🧶 Beaded strings - Pass the thread through cardboard parts and fix beads on both sides.
• 🔩 Plastic rivets (of stationery) - a reliable option for heavy parts.

Example of a robot arm mechanism:

1. Cut your shoulder, forearm and brush out of cardboard.
2. Connect them with paper clips, leaving freedom of movement.
3. Attach the threads from the shoulder to the body of the robot - when the thread is stretched, the hand will rise.

Decor and electronics

To make the robot look realistic:

• 🎨 Use it. dyes or spray-paint for metallic effect.
• 💡 Install. light-emitting diodes eyes or chest (for example, through holes in cardboard).
• 🔊 Add in. buzzer Or record a voice through a small speaker.

You can use traffic control to control the movement. Arduino Nano and servos. For example, program the robot to wave its hand when you press a button.

Tips for improving the cardboard machine

Even a simple model can be a masterpiece if you add a few “chips”. Here. 10 ideas for an upgrade:

1. Structural reinforcement - Pour the cardboard. painter or soak glue for moisture resistance.
2. Moving elements Add rotating wheels (from the lids) or swinging platforms.
3. Sound effects - Use the module. DFPlayer Mini It's for sound reproduction.
4. Remote control - Connect. Bluetooth module HC-05 And you can control the machine from your smartphone.
5. Sensors. - set it up infraredSo the machine can react to movement.
6. Illumination — LED tape It'll add to the effect on the batteries.
7. Magnetic locks - for machine-safes (use neodymium magnets).
8. Hydraulic Water syringes can serve as simple hydraulic actuators.
9. 3D printing Print out plastic gears or parts for machinery.
10. Interactivity Make the machine part of the board game (for example, for rolling dice).

If you want the machine to last longer, avoid it. direct sunlight and high-humidity - The cardboard can deform. For storage, use a box with silica gel (shoe bags).

Safety and Mistakes of Beginners

Working with cardboard seems harmless, but there are risks here too. Here. quirky And how to avoid them:

• ❌ Too thick cardboard It is difficult to cut with scissors, and the details are uneven. Decision: Use 3-5 mm thick cardboard or cut it in layers.
• ❌ Weak connections - The glue doesn't hold, the details diverge. Decision: Strengthen the joints with paper clips or strips of tape on the back side.
• ❌ Overloaded machinery - The bands break, the threads get mixed. Decision: Test the mechanics on the go and reduce the load.
• ❌ Sloppy paint - The paint is smeared, the cardboard is warping. Decision: Put the paint in thin layers and let's dry.

⚠️ Attention: If you use hot-glueNever blow on it to speed up cooling - it can cause burns to the lungs. Let the glue freeze naturally or use it. fan at minimum speed.

When working with electronics (LEDs, Arduino) observe the polarity of the connection and do not exceed the permissible voltage. For example, most LEDs are required. 2-3 B.So use it. current-resistors (220-470 Ohms).

FAQ: Frequent questions about creating cardboard machines

Can you make a machine without glue?

Yes, you can use glue instead of:

• Double-sided Scotch (for light parts).
• Paperclips or pins (for fixing movable parts).
• Plastic rivets (sold in stores for creativity).
• Strings or rubber bands (for connecting parts "on loops").

However, for strength, it is better to combine these methods with glue.

How to make a machine waterproof?

To protect the cardboard from moisture:

1. Cover all the details. varnish (in 2-3 layers).
2. Plug the surface. self-adhesive or painter.
3. Use it. waterproof (e.g., Titan.).
4. For street projects add canopy plastic.

Remember that even processed cardboard is not permanent – avoid prolonged contact with water.

Where can I get the templates for the machine?

Templates are available:

• Find it on the Internet (on sites like this) Pinterest or TemplateLab - Search on request. cardboard automaton template).
• Draw by hand, using photo-projects as a sample.
• Create in graphic editors (for example, Inkscape or Adobe Illustrator).
• Download from specialized books on cardboard (e.g., "Automata and Mechanical Toys" Robert Racela.

For children, simplified templates with large details and a minimum number of slices are suitable.

How to get a machine to move without electronics?

Mechanical movement can be organized by:

• Rubber - the strained rubber band upon release returns to its original position.
• Counterweights The weight on the lever creates movement when it shifts.
• Balloons An inflated ball that releases air through a tube can rotate the blades.
• Hydraulics Syringes with water connected by tubes transmit pressure.
• Inertia - Flywheel of cardboard, untwisted by hand, rotates for a long time.

Example: walking-robot Make your feet out of cardboard, connected to the axis, and unwind it, and the robot will walk on the table.

What can I replace cardboard with?

If the cardboard is not available, use:

• foam-plastlast It is light but fragile (suitable for decor).
• Plywood (3 mm) - durable, but requires a jigsaw for cutting.
• Plastic bottles - for round parts (wheels, body).
• Corkboards - soft, easily cut with a knife.
• Corrugated paperboard from egg trays - for small details.

Each material has its own advantages: for example, foam easy to paint, plywood It can withstand heavy loads.
