Irresistible to make! A collection of motor craft ideas that captivate adults (1–10)
handheld vacuum cleaner
You can make a handheld vacuum cleaner using a plastic bottle as the main body.
Fix a propeller made of thick paper to a motor, secure the motor assembly to an insert cup holder, and then combine it with a plastic bottle with the bottom cut off to complete the build.
When you turn on the switch, the motor spins, the propeller rotates, and an airflow is created from the bottle’s mouth toward the bottom.
As a result, the setup allows debris to be sucked in through the bottle’s mouth.
If you equip a sponge or a fine mesh in front of the propeller as a filter, it should be able to pick up even finer dust.
belt conveyor
You can even make a belt conveyor using a motor.
All you need are familiar materials like plastic bottle caps and cardboard.
If you stick the template onto the cardboard and cut it out, you won’t misplace any parts.
The main conveyor section is made by laminating and gluing several sheets of cardboard, which makes it surprisingly sturdy.
Attach a motor to spin the plastic bottle caps, and your belt conveyor is complete.
With some creativity in how you use it, this device could even make everyday life more convenient.
Elevator
The idea is to build a LEGO elevator powered by a motor.
The motor’s power is transmitted to a pulley, which rotates a shaft connected to the pulley.
A kite string connected to the elevator is pre-wound around the shaft, so when the motor runs, the string is first unwound and then wound back up.
This mechanism makes the elevator move from top to bottom and then back up again.
There are also clever details, such as setting a loose connection to the pulley so the motor freewheels after the string is fully wound, preventing strain.
motorcar
When it comes to projects using a motor, you naturally want to make a car! The key point, then, is how to transmit the motor’s power to the tires.
In this idea, the power is transmitted by meshing the ridges of a plastic bottle cap directly with the motor’s gear.
It’s probably the simplest method.
Also, this idea is full of clever touches: a milk carton is used to make a lightweight battery box, a styrene board is used for the chassis, and rubber bands are wrapped around the tires to prevent them from slipping.
When you make this motorized car, it could be fun to think about where you can add even more improvements as you build.
medal game
You can make a medal game with materials costing under 2,000 yen.
What you’ll need includes MDF, a gearbox, casters, and so on.
Being able to draw lines exactly as shown in the plans is key to success, so take your time and don’t cut corners.
The crucial point is converting the motor’s motion into the action of pushing out the medals.
If you build a few projects that use motors, you’ll likely come up with ideas for how to use them.
The building steps are explained carefully, so give it a try.
hovercraft
A hovercraft is an amphibious vehicle that floats and moves by blowing air downward.
You can make one using a motor and an empty instant noodle cup.
To build it, cut out the bottom of the cup and attach a motor with a propeller—mounted on an ice cream stick—to that opening.
Whether it hovers properly will depend on the overall weight, the propeller size, and the motor’s RPM.
Start by making a prototype and find the right balance.
Try changing the propeller size and adjusting the voltage supplied to the motor from the power source.
spiral lift
Let’s try making a spiral lift that gradually rises and, before you know it, carries the marble all the way to the very top.
This is a spiral lift for a marble run: the marbles that are lifted by the mechanism then roll down the marble run course, and when they reach the bottom, they are lifted up again by the spiral lift.
Using this system, you can watch the marble run operate automatically forever.
The mechanism works by winding a thick cord around a rod and rotating that rod with a motor.
Give it a try and build one yourself.
