In this material, we present to your attention a review of a video on the manufacture of a typewriter with a motor.
We recommend starting with watching the author’s video
So we need:
- 3-volt motor from a cassette player;
- 3 finger batteries;
- metal washer;
- electrical tape;
- toy car.
At the very beginning, we note that the author advises using a machine in which there is a mechanism that moves it forward after rolling back.
We disassemble the machine, and cut out the mechanism mentioned above.
We take out the gear from the mechanism and glue it to the motor with a glue gun.
There should be one more small gear on the shaft. The motor must be glued so that the large gear touches the small one.
We connect 3 batteries in series, so that the minus of the middle battery is connected to the pluses of the extreme ones. You can connect the contacts with metal washers. Between themselves, the batteries can be connected by electrical tape.
We assemble the machine body, not forgetting to bring the wires coming from the motor.
We connect the negative wire from the motor to the negative on the extreme battery.
Next, we take another wire and connect it to the positive contact of the second extreme battery.
Install the battery pack on the roof of the machine.
In order for the motor to work, and the machine began to move, you need to close the plus wire coming from the motor with a wire that is connected to the battery positive terminal.
According to the author, special attention should be paid to the correct alignment of the motor, since the speed and range of the machine depends on this.
