I read the message and really wanted to have such a thing! Tell me how you can do it.
Description from the Internet: Included are two "eggs" - one for each.
The principle of operation is quite simple: one person touches the "egg" - and at this moment the other person's device begins to sway, indicating that one person remembers the other. It works even if people are in different countries. How do I see the implementation myself:
Data is transmitted via wi-fi.
Since there are no buttons and interfaces, I can’t imagine how to go to Wi-Fi.
I think that you need a micro-USB port for charging and for connecting to a computer. That's through it, and you can configure access to wifi.
Need a mechanism for swinging. In general, there could be anything, as long as it was not sudden movements and not a “vibrator” (as in a telephone).
