 publish the stuff here — this is mostly cargo cult code that has been hammered
 into some semi-working form.

+The code behind my https://xenoworld.de/2017/01/18/blink.html[fluorescent light demo].
+
+=== humidity-led-indicator/
+
+Code for a small project which uses a humidity sensor (DHT22) and an
+APA102-RGB-LED to indicate if the current humidity is in an acceptable range.
+*red* means it is too dry, *blue* means it is too humid, everything else is
+something between yellow-orange and green.
+
+It would also switch off the LED if it was too dark in the room, so it would
+not annoy me at night.
+
+At some point I will polish that code and move the whole thing from breadboard
+to a more fixed setup. All components are here, but I haven't gotten around to
+doing it yet. I'm targeting some ATTiny, though.
+
+The original file name was `sketch_humidity_cargo_cult.ino`, so take that into
+account…
