This weeks update is a bit more then I figured. I got quite a bit completed on the building of the globe. As you will see I created the base for the globe, top part to support the north end of the globe and have the LED's attached. I am trying to see if I can make it more 3D by giving it depth with a second row of LED's on the inside of the globe. This way I can produce 2 pictures at 2 different depths at the same time. As always, anyone want any of the .dxf files for this project please ask, I will send them out!!
Below are pictures of the globe so far:
Outside row of LED's
Inside Row of LED's
Support post in the bearings
I had to firgue out how to power the RPi and the LED's. Since the globe is spinning, I can't just run the power cord to the hardware for obvious reasons. I plan on using the bearings as the power connection. One for the positive and one for the negative. I will attach one half of the wire to the outside of the bearing and the other half to the inside. Hope it works!!
Below is a very short video of the globe turning (By hand) no motor is hooked up yet.
