Which bin do I have to put at the curb for collection today?
This notifier will tell you by coloring its lid in the color of the bin!
(In my municipality we have 4 colors: green = compost, blue = paper, orange = plastic, gray = all other.)
I saw the wheelie bin of Jigsawnz (https://www.thingiverse.com/thing:2247931) and this idea popped in my mind. Full description of the project is here: https://www.ewak.net/blog/2021/20210118-wastebin-notifier/
I hope this inspires you to create awesome things!
