Step Three: Repeat, repeat, repeat! For my large 16″ disco ball, I used one full sheet of each color plus about half of a second sheet for the orange and gold bands. Once you have added all the vinyl, your disco ball is done and ready to shine a rainbow all over your home. Make sure that you can easily turn the long metal shaft and the gears all move smoothly inside. If you can't move it easily, the motor won't be able to turn it either. Until I, Kara, bought my first disco ball, I never realized how much sheer joy they can bring to a room. That cascade of bright dancing lights when the sun hits is pure magic. So much so, that now I am now under the impression that everyone is in need of a disco ball in their home!

Sure, you can have a plain silver disco ball (I have two!), but with a little time and DIY prowess you can turn that plain disco ball into a rainbow one that actually reflects colorful balls of light. And look how pretty it is in all its rainbow glory. Then push the motor into hole in the gearbox and test it again. You should see the shaft moving like in the video: This instructable shows you how to make a solar powered rainbow disco ball! A tiny solar panel powers a motor that turns a few cut glass crystals in the sun. These project moving rainbows around your room! I’m sure by this point you all may think I am crazy to undertake a project of this time commitment for a disco ball, but seeing that rainbow of light across my wall totally made it worth it! Plus, how awesome would it look next to a rainbow glitter tumbler? xo. Kara You can also use a veroboard, or you can solder it all together with no board. In which case, have a look at the attached circuit diagram.Finally, fit the top of the gearbox on and push it together round the edges. This can be quite stiff, but look to see where each of the 3 pegs locate and give some good pressure there.
