My domestic refuse collection is based on three separate bins, each of which has to be emptied at a different frequency (some every two weeks, some every week). Throw into the situation public holidays, which seem to shift the rota by a day (sometimes) and you can imagine how confused I am (not to mention mired in unremoved rubbish).
Today’s invention is therefore a simple battery powered lamp with a timer attached. Each year, the council would supply a list of rubbish collection dates which would be entered into the timer (ideally from a passing council operative’s bluetooth phone).
When a given bin requires to be moved onto the street for emptying, the attached lamp is illuminated.
(Or. the binmen could just do what they used to and wheel the bins out themselves).
