With separate plastic, metal, paper, and glass recycling, composting, and pick up of all the rest, knowing which days to put out which bins can be complicated. Some have turned to high-tech solutions like Darren Tarbard's wonderful "bindicator".
I thought about making something similar, but decided that a high-tech solution isn't always the right one. Instead I made a clock, or rather a clock face. My rationale was as follows: the bin days don't change frequently so no need to call an API to get them, and anyway most councils don't have an API for this sort of thing. Also, I really didn't want yet another thing with a wall wart, or WiFi to configure, or code to debug. Not everything needs to be Turing Complete!
But you can buy cheap clock mechanisms where the hands go full circle in seven days instead of 12 hours. Something like this.
So, I wrote a bunch of code to produce an SVG (and PDF and PNG) for the clock face. The code is here. You end up with something like this which can be printed.
