Lego GBC EV3 Writer
Going above and beyond the call of duty, the YouTube channel 20100 shared this GBC EV3 Writer, which doesn’t just move balls from one container to the next, it sorts them by color—white and orange—and then releases and arranges them to spell out custom messages on a display tray. It’s even slower than an old ‘80s dot-matrix printer, but somehow that makes watching it in action even more captivating.
