Wiring<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Both the light and the motor are wired to a barrel jack adapter that goes to the main AC power supply.<\/p>\n\n\n\n

CAD<\/h2>\n\n\n\n

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.\"\"<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

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.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

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.<\/p>\n\n\n\n

Assembly<\/h2>\n\n\n\n

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!<\/p>\n","protected":false},"excerpt":{"rendered":"
