This widget creates an animated themed ACKspace logo.
Created by xopr
Using this widget
To insert this widget, use the following code:
{{#widget:Logo
|image=/w/images/e/e9/ACKsmass_logo.png
|width=600px
|height=200px
|padding=8px
|float=right
}}
This will give the following result:
Notes
- it will display snow in December - March and will show Christmas lights between 7 December and 7 January
- image is mandatory, the rest is optional.
- it also must be written without protocol since colon (:) is not allowed, and may be relative, for example: //ackspace.nl/w/images/e/e9/ACKsmass_logo.png or /w/images/e/e9/ACKsmass_logo.png
- You must provide a unit for the sizes (i.e. px, %, etc.)
Also note that there is a chain of browser extensions and apps within the espixelflut github repo:
- FlutLogo app connector extension.crx: the extension that listens to the UDP connector app and drives the logo "LEDs" (source available, but it needs a static ID for the connector app)
- FlutLogo UDP connector app the app that listens to UDP ART-net packets and connects to the browser extension
- FlutArt: an ART-net app that can be used to control lights (which also works on the browser extension)
Note that if you want to use the LED sleeve python code from bitlair, you have to provide a different listening port to avoid conflicts, like this:
./fire2.py port=0 addr='[("127.0.0.1",6454)]'
