I want to create a stream of water that emits only a droplet of water, waits a few milliseconds, and then continues. The important thing is that I need to create a visible gap between drops.
Considering the desire to have droplets created with a consistent size and shape (asked in this question), how would one go about creating a stream analogous to a morose-code-stream of droplets?
I'm considering having a solenoid valve connected to a tube pointed downward, where capillary action holds the water in place. The solenoid releases the amount equal to one droplet of water. What I'm having trouble with is making the drops look semi-uniform as they fall.
Here is an artistic rendering of what I'm trying to accomplish:
