First things first, fantastic job by @Geokscott. I found his design perfect for replacing some of my 28BYJ-48 stepper motor blind automations. I like him had issues with those motors being strong enough for my larger blinds.
This is a quick remix to make cutting off the bottom tab of the servos a bit easier and cleaner. It holds the servo in place and has a guide for a small saw to trim. My saw blade is ~0.7mm thick, so the slot is sized at 1mm - with the goal of minimizing wobble and keeping a nice flush cut.
I have also included a simple “tray” which holds a 70mm x 50mm breadboard and friction fits within the blinds. I used that to mount my ESP32 (using an external antenna), as well as a buck converter (12v to 5v re-using my 12v adapter) and some other pinouts which I was using for other sensors (e.g., mmWave radar) which I have stashed in the blinds.
Lastly, I am also uploading my modified YAML which I built on top of his original. I converted it to display a proper “cover” entity in Home Assistant, as well as two additional “switches” to: invert or reverse the direction of the tilting, as well as reset the blinds (rotate fully both directions)
