I've always had an interest in cardboard. When I was 7 I made a car out of it, but I thought that cardboard models were too simple. I decided to make something out of cardboard that was more complicated. I decided on a phone. And yes, it does work. It took the better part of a day to make, but wasn't very difficult to do so. I'm only 14 and have very few skills in wiring and technology, but was still able to to this easily.
Step 1: What You Need
You don't need very many things to make this project. You need:
1. Scotch tape
2. Pen (or sharp object)
4. X-acto knife or other kind of blade
5. Fine point Sharpie
6. Magazine to protect your table when cutting cardboard
7. Old telephone you can completely destroy
Step 2: Take the Phone Apart
The phone i chose was near impossible to open. the base was fairly easy thanks to a screwdriver, but the top part was held together so tightly, i had to pry pieces off of it before i could twist it apart. From there, i unscrewed the circuit board from the phone. I then had all the necessary pieces to work a phone.
Step 3: Cover Phone Essentials With Cardboard
If you have a modern phone, the model you make with cardboard can be smaller because there are fewer components. My phone was pretty old, so it was much bigger than i hoped for. When covering your "guts" of the phone, cut out a space for the keys on a piece of cardboard and for other switches you want to include. On my phone, the mic was at the bottom of the keyboard and the speaker was on the top. Because every phone is different, it is difficult to give specific instructions on how to do this project. After you have covered the circuit board and keys, work on covering the speaker with cardboard so that it stands at an angle that fits your face. My circuit board was too big for the mic to be right by my mouth, so i just had it face straight up. Use tape to hold all this together. Good luck customizing the cardboard to fit your phone. This is the most varying part of the whole project.
Step 4: Make the Base
Make a box out of cardboard for the base. I put triangles with chinks cut out of them into the sides of the box to help you put the phone on the receiver. on my phone, the the theing that hangs the phone up is right above the keys. I put a piece of cardboard right where the "hang-up mechanism" goes when i hang up the phone. Now when i put the phone of the receiver, the phone hangs up.
Step 5: Try It!
Plug it in and call it with a cell phone. Good luck!
