[Work in progress]
A 3D printed sphere with 576 holes for LEDs, and an additional one at the bottom for a micro USB connection. The circuit is a matrix of 24x24 LEDs controlled by a custom logic circuit and a microcontroller. It is controllable over USB by a Python script or by writing routines for the embedded microcontroller (Arduino/Teensy).
I've created a MATLAB script to generate the points so that they are as equally spaced as possible, This can then be copied into an openSCAD file to create the two hemispheres.
The 3D design needs a few final touches before being printed. The circuit has been designed and the components ordered. The remaining tasks are:
* 3D print parts
* Solder and test circuit
* Program microcontroller
* Finish Python GUI
