In this video we review the Orrery made by JK Brickworks of the Earth, Sun and Moon. FREE Instructions for this have been made available by Jason Allemann in the link below. We’ll cover off some of the gearing, key parts and slightly modifications we’ve had to make to get it working from the limited parts selection we have in our collection. This was done for one of our kids school projects and was a huge hit.

Excerpt from Show Notes:
G’day Everyone, Matt Elder of Family Bricks and in today’s video we are going to review this LEGO Orrery of the Sun, moon and earth by Jason Allemann Instructions for this are freely available from JKBrickworks. We’ll cover off some of the gearing, key parts and slightly modifications we’ve had to make to get it working from the limited parts selection we have in our collection. This was done for one of our kids school projects and was a huge hit.
Overall was great to put together an if this is your thing, and /or the kids have a science project in the ballpark, definitely recommend giving it a go. It really helps kids to visualize and understand different orbits and what rotates around what. Also helps for kids to learn key rotation times, like the earth going around the sun in 365.25 days. Of course, anything in LEGO seems far more engaging and tactile, so really hit its mark as a learning objective.
Instructions are pretty spot on if you get out the pieces for each step as you go. While the hand crank is fun for the first couple of turns, you really do need some sort of motor setup to get full value and appreciation out of it. Really recommend making sure you have all the main gears as modifying it on the fly can get tricky depending upon what you are missing.
Great to put it together and really enjoyed it! Having quality instructions like the ones provide really makes a difference. Jason has a huge variety of moving / kinetic instruction models on his website, some free, some you need to pay a token amount for. There are a number of his I would like to build in the future, maybe the actual working safe. What catches your eye, what should we build next?
That’s all from us here at Family Bricks. If you are wondering if I’ve ever made my own moving/kinetic works, be sure to check out my LEGO Scenario standard such as this Star Wars one. Otherwise here are some other videos
