While making a two-way radio requires a lot of technical know-how, home-made talkie-walkies are much simpler to make. For your next creative hobby project, craft classic canned talkies, or set up your smartphone to use Push-to-Talk service and have fun talking to your friends remotely. Completed!
Gather your material
- Two tins tin or aluminum or two paper cups
- 5 to 10 meters of yarn
- a hammer
- a nail
- Canned tin or aluminum cans will hold better than plastic ones. The thread will be less likely to break if it has passed through the bottom of tin or aluminum
Push the nail through the bottom of each tin or cup. The holes in the cans must be large enough to pass the wire.
- Thread one end of the thread into one of the cans. Take the total length of the wire and pass one end through one of the handsets. Make sure you have passed the cable from the outside of the handset to the inside of the handset through the bottom.
- Each tin will act as a handset.
- Attach the wire inside the handset. Pull the cord far enough to tie it without having to go inside the handset.
- If the first knot is not large enough to prevent the thread from coming out of the nail hole, knot the knot over the first knot.
- If you use plastic cups instead of cans for your handsets, leave the nail on the inside of the cup and attach the wire to it. This will help keep the wire inside the cup as it may enlarge the hole in the plastic bottom.
- Make sure you have secured the first end of the wire before attaching the other end to the other handset. If this is not the case, the cable will escape from the first cup.
- Repeat steps 3 and 4 on the second handset. Now that you have completed your first handset, you must put the other end of the lead into the second handset and tie it.
- Again, if you use cardboard cups as a combination, then you may need a second nail that you can use to tie the wire.
- Stretch the wire until it is tight. All sounds are created by waves of sounds moving through a substance. It’s the same thing for the voices and even the sounds coming from the vibrations of the stringed instruments, like the violin or the guitar. This is why the wire must be stretched like the string of a violin so that the sound can pass through it effectively.
- Of course, you should not shoot too hard, at the risk of breaking the wire or tearing it from the bottom of your handsets. Pull enough on the thread to vibrate when you pinch it.
- Talk to the person at the other end. Now that you have finished setting up your talkie walkie use it to communicate. Speak in the handset while the other person is listening on the other side of the handset and sending secret messages.
- Do not pull too hard on the wire connecting cardboard cups or tin cans or aluminum cans using your talkie walkies, as this may tear the cable from the containers or boxes.
- If you make your handsets with tin or aluminum cans, be careful when placing your ear or mouth close to them in case the edges of the boxes are shredded.
