Schematics

Wiring

With immensely valuable help from Zeke, we wired the circuit for the light and motor. A driver was added in-line with the LED to limit its power usage, as it got incredibly (dangerously) hot when unrestricted. Additionally, the LED was attached to an aluminum post using a thermal sticker to act as a heat sink as well as the structure holding the light inside the main lamp.

Both the light and the motor are wired to a barrel jack adapter that goes to the main AC power supply.

CAD

The t-piece, motor cap, and base need to be 3D printed, and so I have started to CAD them using Solidworks. Currently, I have the t-piece and motor cap designs finished and am working on finding the best way to print them.

These two pieces will be connected by a nylon band that will sit in the groove and drive the t-piece to spin. The t-piece will be held in place by a bearing which will be connected to the outside of the case.

Art

Drawing from my main two inspirations and previous prototypes, I have finished carving the main shade piece using a Dremel tool (which was much more effective than hand-carving). I still need to finish drilling all of the through holes, clean up the split at the bottom so the bottom piece (not pictured) is easier to reattach, and then paint.

Assembly

The last piece I still need is the shroud that goes around the light and is spun by the t-piece. I have ordered some clear plastic dome pieces that should arrive shortly, and once they come in I will just need to finish printing the necessary parts and assemble!

    Awesome update! Still not going to use a thermostat just for additional safety?
