Barista or Painter? Part 2
Testing the old manual method for comparison.
The result is clear: the traditional method works fine for the walls, while the spray setup is much better for the ceiling and corners.
The tech part? That small box contains a NodeMCU v3 and a DHT22 temperature and humidity sensor, installed in 2018.
Today I am also a painter. But I am a Barista and a nerd every day 🙂
