It is a great project for anyone who enjoys tinkering and building things to build a mini walkie-talkie. It is possible for anyone interested in learning more about electronics and the ability to build circuits to build their mini walkie-talkie with a few simple materials.

To build your mini walkie-talkie, you will need the following materials:

  • An additional 9V battery is required
  • Battery holder for 9V batteries
  • Transistor with NPN configuration
  • A 10K resistor should be used
  • The resistor of 100K
  • There is one small speaker
  • A length of wire equal to one
  • A single piece of perforated board

It is important to solder the components on the perf board correctly, with the flat side facing up on the transistor. Once the components are soldered, you can connect the battery and test the circuit. When you press the switch, you should hear a loud tone if everything is working.

If you do not have a small box or container on hand, you may use it to build the housing for your mini walkie-talkie. Make sure to drill a hole for the speaker and add an antenna hole to the box. Once the accommodation has been completed, the perf board can be glued in place and the battery reattached.

There you have it! You have completed your mini walkie-talkie. You can experiment with different antenna lengths to see how they will affect the range of your device. Have fun making changes and experimenting with different ways to make your device better over time.
