LEGO Orrery Gets A Real-Time Drive Upgrade
An orrery is a beautiful type of mechanical contrivance, built to demonstrate the motion of heavenly objects. LEGO happens to offer just such a device, built using its Technic line of blocks, shafts, and gears. Only, it has a serious limitation—it has to be cranked manually to make it spin the Earth around the sun. [Görkem] set out to fix this glaring oversight with some good old-fashioned hardware.
The setup removes just five LEGO pieces from the original design, eliminating the hand crank from the mechanism. In its place, [Görkem] installed a NEMA 17 stepper motor, paired with a custom PCB mounted on the back. That carries an ESP32 microcontroller and a TMC2208 stepper motor driver set up for silent drive. Rigged up like so, the orrery can simulate the motion of the Earth and Moon around the Sun in real time. There’s also a knob to track back and forth in time, and a button to reset the system to the correct real-time position.
The final build looks great, combining the LEGO Technic parts with some chunky electronics and 7-segment displays that make it a wonderful techy desk decoration. Down the line, [Görkem] hopes to offer a plug-and-play kit to others who wish to duly animate their own LEGO orrery sets (set #42179).
We love a good LEGO build around these parts. We’ve featured everything from parts sorters to functional typewriters in the past.

@liaizon and this BTW is why the platforms that compose the Fediverse can and are used also by fascists and their friends (Gab, “Truth” Social, etc) yet those instances are NOT part of the Fediverse.

@artemis Sometimes, some people don't want to see. And there is no person more blind than the one who doesn't want to see. But, no, that doesn't excuse them.
