DIY Modder Powers Microcomputer with Stirling Engine
TL;DR. A Reddit user developed an off-grid microcomputer, running retro games, powered by a custom miniature Stirling heat engine that generates just 150 milliwatts of power. - The steampunk-inspired device integrates an ESP32 C3 microcontroller, an OLED display, and a 16-key keypad. - The project took about a month to design, build, and program, featuring custom 3D-printed parts and laser-engraved wood. - Its primary function is to operate simple applications like Tetris, Snake, and Pong on extremely low power.
- A custom-built microcomputer operates entirely off-grid using a miniature Stirling engine for power.
- The device features an 80 MHz ESP32 C3 microcontroller and can run retro games like Tetris with only 150mW power consumption.
- The creator spent a month designing and constructing the steampunk-style computer with custom and repurposed parts.
