thingiverse

This Orrery is motorized and includes an illuminated Sun, Moon Phases, Moon Declination, a Sidereal Pointer, Seasons, Days of the Year, a North Star Pointer, and an Hours Wheel. There is a short YouTube Video Here: https://youtube.com/shorts/rH0CS2QWO1Y (Note: Thanks to Feedback from Markus, I have updated the Instructions to .doc file. Thanks to Thingiverse the instructions are now the last file in the stack). It is based primarily on the excellent work of Dr. Phil. His work was the primary inspiration for this Orrery. See his work at: https://www.instructables.com/Sun-Earth-and-Moon-Model-Tellurion-Orrery-With-3D-/ (Note: Copy and Paste the Link in your Browser. The Link is correct but will show up as broken in Instructables probably because of the -/ at the end not being part of the link.) This Orrery has a variable speed drive, as well as forward and reverse switch. It is a 6 volt system with batteries on board so it is portable. Much of the construction is assembled with set screws so it is easy to assemble and disassemble.
