ESP8266 Tamagotchi

What is it?

ESP8266 Tamagotchi is a electronic pet from the 90s. It can eat, shit, sleep and everything else that pet should do.

Key component of the board is a Wemos ESP8266 mini board, that is connected to SSD1306 OLED screen with 128 by 64 pixels resolution (which is plenty, considering 32 by 16 resolution of the original)

I designed it to assemble it together with my 6-years old son. End result is nostalgia filled handheld toy.

Main features

  • Wemos D1 Mini MCU board
  • Custom motherboard with step-up voltage converter
  • SSD1306 I2C OLED screen
  • 3 push-buttons
  • M2 harness that keeps it in one piece
  • Dual AAA Battery holder
  • Buzzer
