Saving Water Using LEDs
Brilliant!Congratulations on: 1) Recognizing a real-world problem. Water is a very precious resource, and water-wastage a huge problem which only makes an already desperate situation worse.2) Approaching the problem with practicality and cost in mind.Avoiding the natural tendency most of us would have had, namely to reach for the Arduino and have that control the led's. Instead, looking for, and finding, a cheap, reliable and simple way of showing how full, or empty, a rooftop tank is by using a minimum of easily-sourced parts.3) Bringing a touch of genius to bear.Problem solved simply, cheaply and (semi)permanently, doing your country, and others, a real service.This is probably the best Instructable I have seen here yet as regards potential World Impact.I hope you win by a country mile..
I use Vaseline on the legs of our hens to treat (kill) Scaly Leg Mites, an awful little creature that can cause the girls great pain. A thick coat of Vaseline smothers the Mites, killing them quickly. Repeated treatment, as part of a cleaning regime keeps them at bay too.
