Media - esp32
I'd wanted to order a handful more ESP32 microcontrollers from Adafruit a few months ago, but they were entirely out of stock so I put my email address in to be notified when they were available again. A couple of weeks ago I got an email saying "The Feather HUZZAH32 is back in stock! There are 2997 available." I... think that might be enough, haha. I ordered three and they arrived today. One of the things I want to do is to rig up a physical button that will turn off the LCD displays that are attached to the Raspberry Pis in the lounge room which display the current temperature inside and out, as well as the time. Even though we run them at a significantly-lower-than-maximum brightness, they're still very bright when we turn all the lights off when we're going to sleep. They automatically turn off at midnight and come on at 8am, but sometimes I want to turn them off earlier, and also occasionally I'm up before 8 in the morning and instead of the temperature and time I'm greeted with black displays. Should be a fun little project!

I made an LED go blinky and fadey! (This is attached to my ESP32 running MicroPython because I'm more familiar with that than C++ on an Arduino.)

Woohoo, my two extra ESP32s arrived, and just in time for my four-day weekend! Going to be doing a bunch of mucking around with MQTT.

There we go, my ESP32/e-ink setup is done! This one is living in the office so we can see the current outdoor and indoor temperatures at a glance. I chucked the code up on GitHub because there was a bit of trial and error involved: https://github.com/VirtualWolf/featherwing-temperature-displayer. This is using CircuitPython not MicroPython, and there's fewer resources available and fewer people using it, it seems.

My additional ESP32 bits arrived today as well! I had to solder the headers onto the ESP32-S2 myself, and while it's not an amazingly neat job, I think it should get the job done.

Hell yeah, this weekend's project was recreating my Pi Sensor Reader (https://github.com/VirtualWolf/pi-sensor-reader) in MicroPython on my shiny new ESP32s! It's done (https://github.com/VirtualWolf/esp32-sensor-reader) and I've currently got it running and posting updates to a copy of my website running on the Mac mini, to test how reliable it is.

YAY my ESP32s arrived! They're smaller than I thought they'd be (and arrived faster than I was expecting, they only shipped from the US six days ago).
