Just finished mine, based on @makai work published here Air Quality Sensors + E-Ink Display using ESPHome.
I had to rotate the screen because that’s the space I had on the wall. Also changed a few data fields
and positions because of the sensors I am using and from a designed prospective.
The frame was DIYed from red oak, powered AC power with a small USB adapter.
