Here is a new Tamagotchi project inspired by the Android retrogame boOp I created Size : 3.96 x 5.60 x 4.17 cm. Material: Natural Full Color Sandstone. The goal is first to make it a classic Tamagotchi, the 'B' shaped button to control it (food, hug, etc...) It will change color depending on its mood using an RGB diode I'm adapting the 3D file to accommodate batteries and a switch. The robotic version will include: an attiny85 plugged into a homemade pcb, two diodes for the eyes, an RGB diode controlled by the ATTiny to change the color according to its mood, a tilt switch (shock detector) to manage when it is lying down and sleeping. I even foresee him dreaming ;). Then I plan another prototype that communicates with Wifi (ESP32 probably). Note: the robotic version requires iterations at the 3D Printing level, in electronics (PCB) and in code. I therefore sell the 'outburst' non-robotic version to finance the development of the robotic version.
