Engineer James Brown from New Zealand in June demonstrated a project of a miniature monitor made of Lego parts.
He played Doom on it, using a compact monitor to display the image. Now the enthusiast has shared the details of the updated project.
The Lego monitor has a 72x40 pixel OLED screen and features an STM32 microcontroller with a 48 MHz Arm Cortex-M0 processor and 16 KB flash memory.
Brown was able to design a circuit board that took up the space between the monitor and the front surface of a Lego part only 0.1 mm wide. He placed all the major components on it and sent his design to the board manufacturer, paying $40 to make it.
