This is the Bearing mechanism lamp! It's meant to make ever changing light and shadow effects. It can do this because you can change the lamp shades. Also you can combine a big and a small lamp shade together. Additionally they also turn around in opposite directions. This way you get endless different light reflections on your walls. In addition I have made different lamp shades to experiment with. You can use only one shade or experiment with different ones together. Also different colours give other effects. If you don't like my lamp shades, you can easily make one your own.
In total I have 4 different (big and small) lamp shades now. See pictures. You can print them flat on your printer and then roll them up and put them in the base ring. I had to make each shade in two pieces because not all people have big printers. You can connect these 2 parts additional with M3 bolts and nuts, but you may glue nail etc also :-) As an experiment I also made some lose trees and animals you can push in the rings instead of the lamp shade.
The light source are LED strips I got out of a cheap usb light. See picture. In my example I used 2 of them, but you can use 4 in total if you wish. The LED stript are mounted on a bracket with a pivot point so you can adjust the angle. This way you have more experimental options. These LED strips work on 5V so its easy to use.
This mechanism is powered by a little stepper and an arduino.
In the base of this model the print support is already included. This means you have to cut this away afterwards. See picture (it's the red parts)
Beware: there are two different sizes of cylinders for the bearing part : see picture.
This is a nice site but unfortunately I have more material I can not upload on this site. For a video arduino script & more foto's see Thingiverse
