LEGO Saturn V and Lunar Module Come to Life

Recently I decided to make a major update to this project, with the end result essentially being the same but all of the components and code being updated/replaced.

Why you might ask? Partly just-because, but also largely because my son has gotten old enough to be a big fan of LEGO and space (and I happened to have bought a second Saturn V a long time ago), so it made sense to redo mine and then have an easier way to duplicate it for him (as well as a variation for his younger sister). Major changes include:

• The base/mount for the Saturn V is now completely 3D printed and also includes LEGO connection mounts (allowing for a loose fit, or if you remove a piece from each engine, a VERY snug fit).

• Switched the MCx to an ESP32 and now use ESPHome for the code
• Added internal speakers (as well as the line-out I had before)
• Swapped a few components, as the originals weren't natively compatible with ESPHome.
• Milled my own PCB

I've updated the Thingiverse link with the new 3D models in case anyone wants to use them as well as uploaded the KiCAD files for the PCB. Here's the ESPHome YAML (mostly-done, but still a bit of a work-in-progress):

Since having originally created this project, I've discovered the amazingness that is Home Assistant.. I'm all-in on HA and am slowly including my homemade projects into it by adding the necessary code. I've uploaded the modified code to Github and renamed it since most folks probably won't care about this part.

If you aren't familiar with Home Assistant, check it out!

I created a mission control 'console' for controlling this project, and created a new project page for it. Check it out!

After a month+ of periodic removal and usage, the attachment point between the LEGO LM and the LM Mount printed piece got loose enough that the LEGO easily tipped. I adjusted the dimensions just a tad and it is now quite snug. All files on Thingiverse have been updated accordingly.
