What kind of motor to use for a Disco Ball

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

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

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

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

Amazon has disco balls. But why?

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 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.

actuators used in the RC robot realm.

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.
