I made a night/morning/wakeup light using an array of 9 neopixels (hand-soldered).

Code is at ... on/neolamp

  • I had to power the Neopixels off 3.3v, on account of a large voltage difference between the 5v power supply and the 3.3v data channel [1]
  • I am crunched for memory on an ESP8266, even with all my frozen byte code! Any new features I add will basically require an ESP32.
I will post a blog about this, once I get some free time (never).
