This is a Giant desktop LED. Its constructed to take a WEMOS D1 Mini and connects to the Adafruit IO service. I am using it to tell me when certain users I follow post on twitter by lighting up and in addition it has a push button so that you can cancel the alerts once you have seen them.
It started out as a copy of 3035829 , but the lens has been redesigned with a twist lock, the lighting ring now uses an NeoPixel 8 LED ring and is slimmer so as to look more scale. The base also incorporates a push button and there are bolt mounts so it can all be connected together robustly.
In addition there is now a version with a 128x32 OLED so you can also show status messages and last author post. Both bases are in the download and you can choose which one you want.

The lens and lens lip was printed with Sunlu transparent PLA which worked better than expected. Also it was only £17 a reel.
