I've noticed that some things can make the price suddenly skyrocket. Certain PCB specifications for one (though couldn't name anything in particular off hand). The one thing that caught me by surprise was that if I…
I was actually pleased with how cheap it ended up: less than $20 USD for the board + assembly + every component. I set ESPHome to use IDF under the hood, you can check out my full ESPHome config for this:…
That's exactly what I did :) and a convenient thing I realised afterwards is that the push-button function of the rotary encoder gives me the ability to turn the thing on and off with my foot!
Fair point, I hadn't thought to consider that aspect of the ESP8266. I mainly opted for the shiny new ESP32-C6 with the idea that I might one day set it up to use Thread instead of WiFi.
Hey, author here. There's a line in the digipot datasheet that says the voltage on the A/B/W pins must be within -0.3V to VDD + 0.3V. The fan's line for the wiper pin is 5V, which would fall well outside of that if I…
Hey, author here. That's correct. The potentiometer has 5V going through it, with a current range of 30-164μA, which fell within limits of the digipot. I opted to use the digipot instead of my own PWM because something…
For the sake of answering the parent question with regard to Chezmoi specifically: Chezmoi is a very comprehensive dotfiles manager. It can do a lot of things. More than any other I'm aware of. More does not necessarily…
I've found many of the devices can now be flashed with https://github.com/openshwprojects/OpenBK7231T_App
