A computer with an OLED display is in this 2×2 nub terminal block.
When it comes to LEGO or clamping blocks, many of us suddenly have childhood memories. How nice it was or is to build a differential or an indestructible crash car from the many colorful stones – more on the latter another time.

There is almost nothing that cannot be somehow recreated with LEGO. This is exactly what the inventor James Brown took up when he came up with the idea of creating an OLED display with clamping blocks based on an original LEGO brick.
Now he goes one step further and doesn’t just build a large replica of the display with terminal blocks. Rather, he constructs his very own LEGO brick with an integrated mini OLED panel. But it’s best to see for yourself:

However, Brown has not only integrated an OLED display into the transparent, angled 2×2 terminal block. In order for the panel to be able to display anything at all, there is also an ARM-based microcontroller in it.
As soon as the blue LEGO brick, reminiscent of a computer terminal, is placed on a conductive element, the mini-computer starts up and displays lines of text that appear to be based on code in their form.

This is how the OLED LEGO brick was born
Brown has made its own mini board for this and equipped it with an ARM Cortex M0 microcontroller. The latter has enough power and sufficient integrated flash memory to feed the 0.42-inch OLED display with text. The screen has a resolution of 72 x 40 pixels. The energy also comes from an old Lego 9V block with conductive knobs.
Incidentally, Brown made the terminal block himself with a 3D printer, which is why, strictly speaking, it is of course not a LEGO brick. The protected brand name LEGO
is now used by many as a generic term for all terminal blocks. Speaking of LEGO:
