Let's make an LED sign that runs on water!
It can be powered by 1 single drop of water, a dead 1.5V battery or a fresh new AA battery.
The circuit diagram is shown within the video. The build makes for an energy efficient DIY project.
In testing, the LED's will run for many hours on a single drop of water, basically until the water evaporates.
Delightfully, the circuit did run on New Years Eve and was flashing away under the TV as we enjoyed fireworks displays from around the world.
