Twitter man and mechanic James Brown made a demonstration out of lego. For this, he used a 2-by-2 chamfered block and a 3D-printed copy of a small OLED panel of the QT1306P82 type. It is powered by the STM32F030F4P6 processor with Cortex M0 core, 4 kilobytes of RAM and 16 kilobytes of flash storage.
The self-designed PCB still needed some major adjustments like drilling a hole, soldering a wire through the board, and breaking the ground layer. Unfortunately, the resolution is not high enough to display text legibly, but it shows how flexible OLED technology is. Perhaps the Danish building block manufacturer will decide in the future to replace the notorious stickers with adjustable OLED panels.
