Automatic rotating base for moon lamp (LED kit)

A motorised rotating base for your moon/Jupiter or other globe lamp.

It's compatible with Tom Fullen's SVS NASA Moon Globe and RynosaurusRex's Jupiter (printed at 150%) or any other globe model provided the opening at the bottom is between 60mm and 110mm.

I also have a version without a motor (you can rotate by hand) which you can find here.

The model is designed around the readily available tiny but strong N20 motor which is found on eBay or AliExpress. These motors run between 3-12v and are available with various gearbox configurations to suit the required RPM of the project. This model is based on the 30RPM@6V gearbox which drives a 110 tooth bevel gear with an 8 tooth pinion gear. This results in approximately 2 rotations of the globe per minute when running at 5v.

The speed can also be controlled by the potentiometer which drops the voltage and RPM - on the lowest setting it's near silent and very slow moving.

PARTS LIST

• Bambu LED lamp Kit (From Bambu Store, or AliExpress)
• N20 micro motor (I used the 30RPM@6v version AliExpress)
• Potentiometer / speed controller (AliExpress)
• 4 short lengths of wire
• Soldering iron and solder

ASSEMBLY

See GIF below for basic instructions

WIRING

The wiring is pretty straightforward thanks to the potentiometer and the LED puck which has 5v and ground pads available.

Double check the potentiometer wire order as yours may differ to mine.

The LED USB cable neatly clips into the underside of the base.
