Computer crafted from traditional LEGO bricks and powered by RP2040 with a miniature OLED display.
LEGO
Played with LEGOs in the 1980s? You probably remember that your spaceman had a computer screen brick for control. Sadly, these bricks were as basic as they come – just small bits of plastic without any actual computer parts or dynamic display functions.

By the end of 2022, it might not be possible for NASA or any of the private space companies that have arisen to construct your LEGO rocket in its authentic size.
Embedding a Miniature OLED Screen and RP2040
Nevertheless, James Brown (AKA Ancient) on YouTube was able to make this small display functional by connecting a tiny OLED screen and the RP2040 in a block with an angular shape.
In order to achieve miniaturization, the PCB is designed using four interlocking sections that fit together like a brick when combined. Aside from very small computing and display components, this is the key.
Accelerometer
Afterward, an accelerometer was added using extra wiring. All four sections were connected through soldering with assistance from 3D-printed jigs and the screen setup was examined to make sure it functions outside the brick.
Assembling with 3D Printing
Brown utilized a 3D-printed assembly and LEGO rods to embed the circuitry into a new resin-cast computer screen brick, proceeding from there.
The outcome is a dark, transparent brick that sits on top of an authentic LEGO power brick, letting the display feature moving outer space illustrations.
Touchscreen Technology
You can also tap the raised parts of the bricks to interact with the screen and change what it displays.
