Over the last 2 weeks I have learned how to use the 3D printers in the ITLL, learned more about the electronics side of things, bought all my parts, and designed the majority of the frame and control panel. I’m going to try to finish the CAD this week so I can prototype and test soon. Below are some screenshots of what I’ve been working on.
This is the central disk that will house the LEDs. The motor with a gear will be inserted on the top disc and the bottom disc’s circular extrude will house the ground wire and will go through a bearing. The small holes on the side are for the LEDs and the larger extrude cut on the top face is so I am able to disassemble it.
Here are 2 views of the bottom half of what I’m calling the truss frame. The top will house the small dc motor, the bottom will house the bearing mount and counterweight, and the left side will house the slip ring. I’m still figuring out how to attach the larger dc motor on the right side to rotate the truss frame. The extruded cylinders are for screws to secure the 2 halfs together.
This is the top half of the truss frame. The 2 smaller extrudes are to secure the motor and the larger extrude is just to cover the motor housing.
This is what I have so far with the overall assembly. So far it weighs 0.8 ounces and has a volume of 1.07 inches. Since this is so small and everything has to be very precise I will be prototyping this on the Lulzbots and for the final product I will pay to use the better printers in the ITLL.
Moving forward I have a good amount of CADing left to do, I need to buy a few more parts, design the control panel, and finish the circuitry.
