I want to make a disco ball. I am thinking of just using a basketball
and gluing lots of 5/8 inch mirror squares to it. But the motor is what
I am not sure about. I know it turns quite slow. Just guessing, I'd
think it rotates about four or five full turns per minute. So I assume
the motor needs to be geared down.

I plan to mount the motor in a metal box, which I can attach to the
ceiling, and have a hook on the motor shaft for the chain that goes to
the ball. Or would it be better to use a solid metal rod, instead of a
chain?

Any ideas or suggestions ?

Bring back the 70's ! Smile

Maybe an AC synchronous motor.. you get get them in a few rpm.

There are plenty of posters here stuck in the 70s but they probably
hated disco at the time - "that's fag music!"

I would suggest the chain to make the unit more portable. Once it is in place it will stop swinging fairly soon. I'm sure once per minute will be fast enough. The effect is from a small change in angle causing the reflection of the light to swing past your eye. At any distance at all this will be very quick even with just 6 degrees per second. So a standard second hand drive should be about right.

I'd look for something lighter weight than a basketball. How about styrofoam? Coat it with something that won't dissolve the plastic or look for a hollow plastic globe. I would shoot for lightweight to prevent it being hard to drive. Even the mirror chips are going to weigh more than enough.

The old rotating Christmas tree light wheel motor. They were single
speed synchronous motors though. You want a variable speed setup
because a ball which can barely move is appropriate for one mood,
and one set to a disco song for a group of partiers would likely be
a bit faster.

You could always use an oven spit motor 4 rpm or thereabouts !

Amazon has disco balls. But why?

you probably need to do something to ensure the ball stays the same
size permanently - perhaps fill it with foam gap filler.

many people purchace foam balls or carve balls from foam.

Some microwave ovens contain a suitable mains powered motor. others have
a motor that wants some odd-ball voltage.

Do you run fans indoors? if not a chain, string, or wire would work.

unless your time is worth nothing go on amazon and order a ~$50 kit with ball motor and light

These motors are readily available. You could look for 1 RPM motor. If
you don't find any, you could get a barbecue motor.
I'd go for a step motor and a arduino for versatility.

I bought a small one at the dollar store for a few dollars. You can easily
find gear motors for a few dollars at Aliexpress.

I assume you'll be adding lasers and a fog machine. Or black light and bring
back the sixties.
