This is just a short set of updates for my weekend projects, meant to keep me in the habit. I’ll write up a more complete version of these projects going forward. First of all, a new acquisition. My Anet A8 3D printer has proven to be, well, not the most reliable of gadgets. I still […]

I haven’t posted an update here recently, but I am (mostly) living up to my New Year’s resolution to spend at least 30 minutes a day working on a project. This has taken the form of some stupid but necessary chores (like fixing the broken pull cord on my lawnmower) but has mostly taken the […]

I spent a little time today trying to make the bare minimum code necessary for the ESP32 to connect to my WiFi network and synchronizing the time using NTP. It’s not really that amazing, but required a tiny bit of snooping around to figure out how to make it work. Archived here, just for fun. […]

If I was going to port my ISS code to the ESP32 using the ESP-IDF framework, I’d need a driver for the SSD1306 OLED display.  It does seem like some people have been down this path before.  I haven’t tried any of the following, but a little quick googling revealed some promising links: https://github.com/yanbe/ssd1306-esp-idf-i2c https://github.com/imxieyi/esp32-i2c-ssd1306-oled […]

Over the last year I’ve spent a small amount of money and a larger amount of time accumulating a bunch of development modules from banggood. This began mostly with me getting some spare Arduino modules cheaply. Whereas an official Arduino might cost you $25 or so from Adafruit or Sparkfun, you can get a Geekcreit […]
