Title：Wireless Toy Phone

|Concept / Overview|
|I would like to introduce how I made a wireless toy phone which I presented at Renesas Night 7. A “Secret Futuristic Gadget” appearing in an anime film inspired my creation. The basic idea was that you could talk from an even longer distance if you eliminated the wire or string connecting the tin can phones we played with in our childhood.
Of course, there are already many examples of instruments allowing us to converse from a distance without wires or strings or cables, including radios, transceivers, and cell phones. The point of my apparatus is that on their own, vibrations from one paper cup, i.e. your telephone, can reach another person’s paper cup, achieving a wireless result.

Avoiding use of a switch
Determining the tilt angle
Here is the circuit design for the wireless toy phone.
The area enclosed in the blue dotted lines is the base board and will be described in the next section.
I used a 3D printer to make a case in order to secure the paper cup and board. I have noted the STL data below but, depending on the size of the paper cup, you may not be able to use it as is. The data is based on a cup 8cm in height and 7cm in width.

Secure the base board with screws.
The power switch show pole out on the reverse side.
The universal board (shield) on top of the base board.
Attach the LED tape and piezo electric effect element on the paper cup and connect the jumper wires.
Set the cup above the universal board, connected the jumper wires, and the gadget is basically ready to go.
I like to fool around with electronic gadgets as a hobby.
I am one of the GR-SAKURA producers so most of my creations are based on Gadget boards.
