Is it supposed to do that?
Figure it out as we go.
I've always been fascinated with the physical world. In particular, digital electronics and lighting. I also enjoy taking my time to understand why things work they way they do, which explains my (sometimes painfully) meandering journey to design and produce a better lighting control system.
Although I've received a formal education in electrical engineering, I've taught myself 3D object design, audio/video production, and coding in various languages. I am enjoying this journey.
Below, you will find links to my recent YouTube videos that document the various aspects of developing this illumination apparatus and my discoveries along the way. Here is a link to the whole playlist starting with the first video in December 2021: https://www.youtube.com/playlist?list=PL8fx2PasT3iDHbZt3daNV69Nn2KMNSdC5
I've also included a few links where you can find some of the source code I wrote for this project.

LED controller FreeCAD 3D model python code
In episode 25 we designed an enclosure in FreeCAD for the controller. Rather than using the graphical interface, we wrote parametric code in Python to create the 3D object. If you like to explore deeper, the button below leads to my Dropbox where you can grab the code.
Rotary encoder schematic
The circuit schematic from episode 16, in which we designed and built a 2-bit quadrature incremental rotary encoder, complete with de-bouncing RC filters to control the intensity of our digital illumination system. Here is the component list:
4x 51kohm resistor
2x 22nF capacitor
2x Schmitt trigger inverters (2 of 6 circuits on a single 40106 IC)
1x D-flip flop (1 of 2 circuits on a single 4013 IC)
1x 2-bit incremental rotary encoder (Bourns PEC16)
