I'm finally working on my chandelier again after finishing spring classes. Grad school is time consuming. I've written a few more visualizations for the TM4C Launchpad-based light cluster, most recently stars that twinkle on and off. It's definitely the coolest image we've had thus far.
Additionally, I've drawn up a custom MCU PCB that replaces the Launchpad. It's about the size of a postage stamp, uses a TM4C, includes all its own power conditioning circuity, and is powered and controlled by a USB cable that carries power and UART commands. As soon as that arrives in the mail, I'll figure most of the mistakes I made in its design, order a second rev, wait for that to get here, and then I'll have a nice clean custom controller for 16 strings.
