Hobby Electronics

There are quite a few hobbies you could have that require electronics. Many people like to build and race electronic cars and airplanes. These can be exciting hobbies for youngsters, but if they are interested in any of these hobbies, they should know a little about how the electronic hobbies work.

It may vary from toy to toy, but many of the electronic hobby toys are operated by radio control. This involves a transmitter, receiver, motor and power source. The transmitter is what you hold to control the toy. This transmitter sends radio waves to the receiver. Transmitters usually have a 9-volt battery that provides the power for it to transmit the signals. A radio controlled toy doesn't have a wire running between it and the radio control because the signals are transferred over a frequency. The Federal Communications Commission (FCC) determines the frequencies to be used by different things. The frequencies 27 and 49 MHz have been designated for radio control toys among other things. However, some more advanced radio controlled toys may use 72 or 75 MHz frequencies. Once you submit signals to the receiver, you can do things such as make the toy move forward, backward, left or right.

The receiver is an antenna and circuit board inside the toy. When it receives the signals from the transmitter, it activates the motor to power the toy. The motor is used to power the toy – to turn the wheels of a car, the propeller of a plane, etc. Motors in the smaller toys may be about the size of a dime. There are two battery leads running from the motor. When hooked up to the battery (the power source), the motor runs and moves the toy.

Radio control toys are great fun to play with and educational toys for children to learn how things work.
